Almost half of existing secondary forests will become new developments over the next 10-15 years (CNA, 2020). The loss of habitat forces wildlife into urban areas, leading to human-wildlife interaction. With RVRC being located beside Kent Ridge forest, there is higher likelihood of human-wildlife encounters. In order to educate and build confidence in RVRC residents as first responders in wildlife encounters, we aim to provide accessibility to information required in handling human-wildlife interactions. QR codes were pasted on residents’ doors. If residents encounter animals in their rooms, they could easily scan the code to obtain instructions on safe handling of wildlife. Survey results indicated an increase in respondents’ confidence in animal encounters from 43.1% to 77.8%. 75% of residents were more likely to respond correctly in human-wildlife interaction scenarios. To continue educating future residents, we plan to collaborate with RV Forestore Interest Group and the Office of Housing Services.

Improper waste disposal and high waste generation of disposable masks have spiked and adversely exacerbated environmental issues since the onset of COVID-19 both globally and locally. Educating and advocating for reusable mask usage would help reduce disposable mask waste. Education with the engaging activities would foster effective learning and change among RVRC participants. Hence, we utilize a two-pronged approach through conducting an educational workshop and supplying reusable masks to change perceptions and reinforce the wearing of reusable masks instead of disposable masks.

We designed a face-to-face workshop comprising i) a pre- and post-workshop and review survey; ii) distribution of free reusable masks iii) discussion of benefits of reusable mask usage. Our findings showed that 90% of workshop participants continued wearing reusable masks the month after the workshop. Hence, our multi-pronged approach has proven effective in promoting reusable mask usage in RVRC residents.

Water supply in Singapore is limited and PUB aims to lower water consumption, and an understanding of water use habits would be useful to implement conservation measures. Our objectives were to evaluate the effectiveness of water thimbles and posters in helping residents save water. We carried out our implementation at two floors by: i) installing thimbles and water meters in their pantry taps ii) pasting water conservation posters informing residents that thimbles were installed iii) conducting surveys to understand residents’ tap usage iv) conducting observations and interviews regarding differences in tap usage.

Thimbles reduced flow rate by ~50%, but total water consumption was hardly reduced despite their installation. Interviews revealed that perceived time spent using the tap was unchanged, though data and observations said otherwise. Thimbles and posters were not proven to be effective in saving water. Residents likely required more direct changes in their water usage habits to save any meaningful amount of water.

There is a need to address Singapore’s high levels of water consumption. While RVRC residents are cognizant of the impacts of water scarcity, they are unaware of how they can contribute to water conservation. Hence, our objective is to encourage collection of cold water which are wasted while waiting for the water to warm up before their shower. Firstly, we found out residents’ showering habits through focus group discussions and surveys. We then developed a prototype that provides the option to funnel cold water from the shower into a bucket. Lastly, we investigated their willingness to collect water through a focus group discussion. Our findings showed that a total of 464.96L of water was collected from approximately 207 showers during the 2 weeks of implementation. Hence, the prototype proved effective in encouraging the collection of unused water during showers, raised awareness about water conservation and made water available for reuse.

Building construction and operation contributes to 39% of global carbon emissions (IEA, 2019). Active control measures to reduce these emissions tend to have a higher carbon footprint than passive design solutions. Our project examined the impact of 3M solar films in enhancing occupants’ thermal comfort and lighting conditions in RVRC tower block. We selected four pairs of rooms with clear variation in direct sunlight exposure, to conduct a comparative test. Quantitative data for parameters affecting thermal comfort (temperature, radiant temperature, relative humidity, air velocity) and light illuminance level was collected. We also conducted interviews with occupants (n=8) to understand their perceived thermal comfort. Data indicated that the treatment rooms had lower Wet Bulb Globe Temperature than control rooms, with a difference of up to 0.94°C. Based on our interview results and data analysis, we concluded that the installation of 3M solar film was effective in enhancing occupant’s thermal comfort and lighting conditions.

Academic Advisor: Ms. Sadaf Ansari

Textile waste is a serious issue in Singapore due to the rise of fast fashion and a “throwaway” culture. Cultivating a habit of reuse is important to mitigate this problem. Inspired by similar past GEQ projects, our objective was to design and test a platform for NUS residents that facilitates the exchange of clothes, and enhances the receptivity to wearing second-hand clothes. We chose a digital tool to make the process convenient and flexible. We designed a group chat with a embedded Telegram bot that allowed users to buy and sell their clothes. It also allowed us to track the number of transactions. During the initial launch period of 7 weeks, more than 60 participants actively used the platform. Our survey results indicated a parallel decrease in users frequency of purchasing new clothes. Hence, our digital second-hand clothes exchange platform was effective in reducing textile waste among NUS residents.

Liquid soap use has skyrocketed in the APAC market in recent years. Its manufacture and use carries a high environmental footprint, while its plastic packaging directly contributes to increased waste. To mitigate this trend, our project aimed to raise awareness about the negative environmental impacts of liquid soap and promote the use of bar soap as an alternative. We designed an interactive workshop (n=21) with three key objectives: i) enhance knowledge about the detrimental environmental impacts of liquid soap; ii) engage participants in DIY bar soap making; and iii) compare commonly used brands of soaps as liquid and bar versions. We collected data from our workshop participants, and also followed up with them three weeks later to check if there was any change in their choice of soap versions. Our results found 95% of the workshop participants were willing to use and encourage others to use bar soaps, demonstrating a change in their attitude.

In land scarce Singapore, solid waste disposal is becoming a prevalent issue. As Singapore’s sole landfill is predicted to be filled by 2035, it is crucial to enhance awareness on the importance of reducing solid waste and to provide useful means to do that. Our group created and tested a digital platform to promote the sharing or donation of hostel essentials amongst NUS campus residents. Based on our preliminary findings, the key features of the Telegram channel allowed residents to i) post items to donate or loan, ii) sieve potential wanted essentials, and iii) receive information about reducing individual solid waste. Our channel garnered 51 unique subscribers and 7 successful transactions over a four-week period, from RVRC and CAPT. Based on results of our surveys and interviews with users, we concluded that the channel succeeded in spreading awareness and providing a platform for residents to share goods.

Academic Advisor: Ms. Sadaf Ansari

The high volume of waste generated from single-use plastic carriers for takeaway drinks is a prevalent issue in Singapore. To mitigate this waste, our project objective was to design and test a DIY sustainable alternative for takeaway drink carriers for RVRC residents. Our cup holder prototype is made primarily from upcycled clothes waste. We first conducted a performance test for our prototype to measure factors such as strength, durability, drying speed and flexibility in use for different drink sizes. Following this, we conducted a feasibility study with our target audience – high frequency consumers of takeaway drinks. After a three-week trial, results showed that the frequency of cup-holder use by the participants in our trial increased gradually while their use of plastic carriers dropped more than half. Hence, we conclude that our prototype could be a a sustainable alternative to replace single-use plastic carriers for takeaway drinks.

Food wastage is a pressing concern worldwide. Within RVRC, accumulation of unaccounted and expired food in refrigerators produces large amounts of food waste. Our objective was to enhance the current food labeling system in RVRC fridges through digitization, while providing a convenient platform for food sharing, thereby reducing food waste. We implemented a Telegram bot that i) logs items placed into fridges, ii) reminds users near expiry, and iii) stores a database of shared food items that users can access. Within the two blocks where we did the pilot implementation, there was high uptake (52% of residents), and consistent engagement with the bot. Fair levels of sharing through the bot also demonstrated significant potential of a convenient sharing system in reducing food waste. We conclude that the bot has application in RVRC pantries beyond the pilot, as it successfully enhances the food labeling system and reduces food wastage through sharing.

Both single-use plastic bags and tote bags pose significant environmental problems. From our pre-survey, we concluded that laziness and inconvenience were the main reasons that hampered our participants from reusing their existing bags. Our objective was to increase both the convenience and reuse rate of tote and plastic bags in NUS, to lengthen their product lifespan. Learning from past GEQ projects, we designed and placed self-operating stands at two different locations on NUS campus. Our stands allowed both donation and taking of tote and plastic bags. Over a three-week trial period, 59 tote and 45 plastic bags were taken by campus users. A total of 50 tote bags and 40 plastic bags were donated at our stand. Thee results indicate that our stand was able to successfully increase the life-cycle of used plastic and tote bags.

Academic Advisor: Ms. Sadaf Ansari

The large amount of e-waste generated in Singapore, together with a low recycling rate, poses a serious environmental issue. Lack of awareness and information regarding e-waste recycling locations contribute to the low recycling rates. Our project aims to tackle these two issues using a digital solution, with the objective of increasing the convenience of e-waste recycling for Singaporeans. With Telegram’s growing user base among Singaporeans, we designed a Telegram bot that presents customised information about the the nearest and most suitable e-waste bins to users, based on their specific location and e-waste item. During the one month launch period, 360 unique users across Singapore utilised our bot. Of these, 113 indicated that the bot had helped them to recycle e-waste, while 90 users stated that the bot would help in future efforts to recycle e-waste. This data highlights the efficacy of our bot to enhance ewaste recycling, and we are currently in discussion with NEA for integrating our bot with their website.

Lack of awareness of proper recycling methods is a key factor in Singapore’s low recycling rate. Hence, inculcating knowledge about plastic recycling is important, especially at a young age, to enhance the recyling rates long-term. Research has established that interactive games are often more effective in sustainability education for children, as compared to structured learning. Therefore, we created and tested a card game for children aged 9-12 years, to enhance their knowledge of plastic recycling. The game was part of an interactive workshop conducted in a school setting with the target age group. Participants were able to understand and retain the knowledge about plastic recycling, with a 35% increase in correct answers after the workshop. The results proved that our workshop and interactive game design are useful tools to enhance and promote awareness about plastic recycling.

Food wastage, one of the biggest contributors of greenhouse gases, is increasingly pervasive in Singapore. RVRC’s dining hall discards on average, 5.28kg of unserved cooked rice from trays daily. We aim to alleviate rice wastage by upcycling the unserved rice into a desirable consumable product for RVRC students. We formulated an easy-to-follow recipe to produce tasty bread made from white and brown rice and proposed the recipe to the dining hall caterers for serving during breakfast. We surveyed students regarding its appearance, taste, and its desirability in comparison to the store brought bread currently served by dining hall. Our rice bread was well-received by RVRC residents, demostrating that our recipe produces a desirable product and could effectively tackle rice wastage in the long run. We will be sharing the recipe with the dining hall committee to discuss ways of serving rice bread made from leftover rice in the dining hall.

Academic Advisor: Dr. Chua Siew Chin

In Singapore, more than 50% of plastics cannot be recycled due to contamination.Our survey of 75 NUS students also found that most students did not rinse their plastic containers before recycling. Hence, we aim to decrease plastic contamination and raise awareness on the importance of rinsing plastics bottles/cups before recycling. To this end, rinsing devices were placed near recycling bins to increase the convenience of rinsing plastics. Posters were placed to educate users on the importance of rinsing plastics before recycling. A survey (n=77) and contamination counts were done throughout the implementation to quantify the completion of our objectives. Our survey reported that 70% of subjects are “likely” or “extremely likely” to rinse plastic bottles/cups with our device, and the contamination rate was reduced by 46%. Both are statistically significant (p<0.01). Therefore, we conclude that increasing convenience for rinsing plastics can effectively improve rinsing rates, thereby reducing plastic contamination.

The Reusable Bag Library, a reusable bag sharing initiative by NUS SAVE to reduce plastic waste, was largely underutilised and unsustainable. Our objective was to address the limitations of this initiative and make the initiative more sustainable to increase the usage and return of reusable bags in the long run.

Using our redesigned sharing system, we launched our project at UTown FairPrice with i) attractive booth and poster designs; ii) booths at each RC; iii) labels with reminders of returning the bags, and iv) system to track usage of bags. With the redesigned booths, 61 bags were used over 3 weeks, a 307% increase from NUS SAVE’s initiative. With the addition of booths at RCs, the return rate also increased from 24% to 47.2%. Hence, the combination of more eye-catching booths with a convenient return system was effective in improving reusable bag sharing initiatives in NUS.

Academic Advisor: Dr. Chua Siew Chin

Singaporeans produce on average 1.011 million tons of paper waste every year, yet 67% are unaware of the non-recyclability of soiled paper packaging, hence leading to improper recycling and contamination of recycling bins. Given that soiled paper packaging cannot be recycled, our objective was to come up with a sustainable and convenient method in order to repurpose non-recyclable waste paper. We investigated optimal mushroom growing conditions to design an efficient DIY mushroom growing kit using waste paper bags from RVRC’s dining hall, and conducted a workshop to assess the resident’s receptivity towards these kits. We determined that waste paper bags were partially successful as a substrate for mushroom growth and 86% of the workshop attendees, after using the kits themselves, were willing to do it again. Hence, our DIY mushroom growth kits are effective in repurposing non-recyclable food-soiled waste paper.

Ugly fruit wastage occurs at every stage of its life cycle. This significantly contributes to fruit wastage, which together with vegetables amounts to half of the food wastage in Singapore (Judith Tan and Vanessa Liu, 2020). The root cause of this is the “beauty-is-good” mindset, resulting in cosmetic filtering. To tackle this issue, we aim to shift RVRC students’ consumer demand which is expected to encourage Dining Hall vendor to minimise fruit wastage and hopefully suppliers, in the future. A blind test juicing booth was conducted to persuade RVRC students that ugly fruits are just as tasty and nutritional as appealing fruits. From our surveys and focus group discussions, we found out that our booth has influenced RVRC students to consume ugly fruits, which justifies our recommendations to the Dining Hall vendor to consider accepting and serving ugly fruits in the near future and the long run.

With the extensive generation of used beverage cartons (UBCs) globally and the inefficient UBCs recycling system in Singapore, it is crucial that the end-of-life of these packages are addressed appropriately. As hands-on activities are more engaging than structured teaching, our objective was to develop interactive educational sessions where RV residents are able to learn and adopt upcycling in their daily lives. Firstly, educational posters were put up around RVRC. Secondly, we held a 2-hour interactive workshop consisting of i) pre- and post- workshop survey; ii) informative presentation on carton materials; and iii) instructions to guide participants to craft a flower pot from UBCs. From the survey results, 84.6% participants expressed their willingness to continue up-cycling UBCs after the workshop. Participants’ upcycled reations from the workshop and exposure to our posters serve as reminders to upcycle, hence inculcating the habit of upcycling UBCs among RV residents.

Forgotten food in fridges has always been one of the main reasons for food wastage in Singapore, including RVRC. Increased awareness of food left in fridges can reduce food wastage. Hence, our approach aims to make food stored in RVRC’s fridges easily trackable while increasing student users’ awareness of when their food expires. We conducted and created i) a pre- and post- implementation survey to understand food wastage patterns; ii) a telegram bot with a food expiry reminder system; iii) boxes to compartmentalise the fridge for residents. We aim to determine the effectiveness of the implementations through i) user feedback and results weekly surveys over the course of one month; ii) data on wastage levels from the monthly fridge cleaning exercise. we believe that through a thorough analysis of the experiment, we will be able to conclude which implementation is more effective in reducing food wastage in RVRC’s fridges.

Waste management has always been a challenge in Singapore due to lack of landfill space. The widespread usage of single-use packaging, especially when coupled with low recycling rates, is unsustainable. Our objective was to test the feasibility of a long-term zero-waste snack store in NUS, and measure its effectiveness at (i) reducing single-use packaging consumption and (ii) changing consumer attitudes toward packaging. We conducted a pre-survey to gather information about RVRC students’ consumption habits and snack preferences. Our store was then operated for 4 weeks in RVRC. It was unmanned, sold loose snacks sourced from zero-waste suppliers, and required customers to use their own containers at purchase. We then conducted a post-survey to measure if habits had changed over the duration. According to the data collected to-date, there was sustained interest and purchases throughout the project duration, suggesting our success in reducing packaging waste generation.

Climate depression is a fatalistic attitude towards climate change which can lead to adverse emotions and attitudes towards actions towards conserving the environment. One main reason is the high exposure to negative news and reports on climate change. Our team aims to address this problem amongst youths through social media and setting up a website highlighting positive news and achievements in addressing climate change. After participating in our workshop and viewing our Instagram page, over 50% of our participants are more knowledgeable about climate depression and are more aware of positive measures and solutions done to solve climate change. This strongly suggests that social media and online resources can have a positive impact on addressing climate depression.

There has been a steady increase in plastic and microplastic waste creation in Singapore. We wish to tackle one facet of this issue by encouraging RVRC students to use more reusable containers when taking food. We did this by improving the washing facilities in RVRC and conducting an educational campaign.
We upgraded the block A pantry by i) installing a tap extension to make washing more ergonomic; ii) improving the pantry environment by using air fresheners; and by iii) replacing synthetic sponges with organic ones (loofahs). We also conducted an educational campaign through i) posters in the pantry, ii) messages in RVRC chat groups and iii) workshops. In doing so, we found that there was a marked improvement from 1-3 to 3-5 daily users of the washing facilities. Thus, we found that a combination of better facilities and understanding has proved useful in encouraging the use of reusable containers.

Nature Deficit Disorder has been on the rise given Singapore’s fully urbanised population. While visiting nature trails, youths do not have much learning experience and are thus less engaged with nature, which reveals a growing disconnection between youths and nature. Our group intends to bridge this disconnection through our mobile application, Trailmix.

Trailmix, targets a segment of Sungei Buloh Wetlands Reserve (SBWR). To test the effectiveness of Trailmix, we designed a pre-post-survey to evaluate the 4 components of connectedness to nature: knowledge, interest, importance, and attitude towards nature at SBWR. Participants first did a self- exploration trail and took the pre-test survey afterwards. Participants then went on either a Trailmix guided trail (experimental) or with an actual tour guide (control). Comparisons between the pre-post survey scores revealed that Trailmix was effective at enhancing the nature trail experience, with comparable results to an actual tour guide.

A survey we conducted found that RVRC residents generated high amounts of PET waste and had poor recycling habits. Our objective was to raise awareness of repurposing as an alternative to disposing PET bottles. We adopted a holistic approach for our project which consisted of i) a repurposing workshop; ii) an exhibition of repurposed objects; iii) tutorial video and iv) Instagram account. Through a pre- and post-workshop focus group discussion, we concluded that the workshop was successful in changing the perception towards repurposing. However, analysis of our post-project survey showed that the effectiveness of the three components ii-iv were limited by the scale of our implementation. Hence, we recommend the repurposing workshop as an effective way to encourage repurposing in RVRC. However, the exhibition, tutorial video and Instagram account will require more extensive outreach to effectively complement the workshop and ensure the long-term continuity of our objective.

RVRC’s monthly food wastage was about 1209kg, or approximately 20kg per meal. Food wastage has been a persistent problem in RVRC. We aim to investigate the effectiveness of peer support on encouraging students to reduce their plate wastage. We recruited five groups of students to participate in our project. From pre-campaign focus group discussions, we gauged their general attitudes and behaviors towards food waste, allowing us to better tailor our peer support techniques. During the three weeks of campaign, participants were tasked to motivate each other to reduce their plate waste through a peer support system. We collected data on the amount of plate waste for two dinners weekly. Furthermore, we provided weekly “dinner table topics” to actively engage the participants in the peer support system. A post-campaign discussion was carried out and the responses indicated a positive impact from peer support in reducing food waste.

Electrical dryers consume substantially more energy than other household appliances. Past projects tried to eliminate dryer dependency, but their results showed continual dependency on dryers for laundry in RVRC. Therefore, we aim to reduce the electrical consumption of dryers by educating RVRC residents on its high consumption through informative platforms – Instagram, stickers on dryers and posters, and to discourage high heat usage by using lower heat whenever possible. We conducted a pre- and post-campaign survey, set up a notebook for residents to record users’ dryer heat setting throughout the campaign and conducted a series of focus group sessions. From our results, i) usage of high heat has decreased significantly; and ii) majority of our respondents have learnt something from our campaign. Hence, educational posters and stickers on dryers proved effective in raising awareness of electrical consumption of dryers, and resulted in users opting for lower heat setting where possible.

Laundry contributes to a huge amount of water usage globally, yet many Singaporeans (RVRC residents included) do not do their laundry on full load. Our objectives were to analyse laundry habits and behaviours of RVRC residents, raise awareness about the importance of full loading their laundry, and examine changes in laundry habits of RVRC residents after our intervention. In order to fulfill the objectives of raising awareness and analysing laundry habits, our approach comprises i) a pre- and post-survey; ii) an educational poster; iii) a weighing scale for residents to assess and increase laundry loads over time, and iv) a focus group discussion. We found out that many residents were aware of the importance of washing on a full load. However, many do not practice washing on a full load due to personal reasons. Overall, our intervention was effective in raising awareness and helping us better understand the laundry habits of residents.

While environmental problems remain a serious issue, many people do not regularly practise sustainability. One of the reasons might be a lack of knowledge of sustainability. Research has showed board games to be effective in teaching about sustainability, our objective is to develop an educational board game for RVRC student participants, to reinforce their knowledge of sustainability and provide everyday solutions to environmental problems. We adopted the board game ‘Terra’ and conducted 3 gaming sessions. Our methods comprised i) a game session; (ii) a pre-quiz and a post-quiz testing participants’ knowledge of sustainability; and iii) a follow-up survey asking for feedback and lifestyle changes supporting sustainability. Quiz results showed that  average pre- to post-quiz scores improved by 21.9%. Also, 88.9% of participants provided positive reviews of the game. 82.4% of participants reported living a more sustainable lifestyle afterward. Hence, the implementation of an educational board game proved effective in reinforcing students’ knowledge of sustainability.

Human toxicity impact from disposal of metal strips within face masks is extremely high. With Singaporeans using more than four million masks daily, coupled with a low recycling rate, there is strong potential for recycling of these metal strips. As digital marketing is one of the most effective tools for engaging a wide variety of audiences, we aim to harness the power of social media to cultivate stronger consciousness of metal strip recycling.

We created an Instagram account with project-related, educational and empowerment posts. We also set up collection boxes across RVRC and gave the metal strips collected away to be reused. With over 1500 impressions on our Instagram account, over 200 metal strips collected and a change in RVRC residents’ mindsets over the course of our campaign, we had achieved our objective. Hence, tapping on social media garnered notable results in cultivating the recycling habit amongst RVRC residents.

27,000 trees are cut down daily and are chemically processed into toilet paper which generates significant water and carbon footprint (Braun, 2017). Our project aims to educate Singaporean households, by using youths as a proxy, that toilet paper generates a high environmental footprint, and increase their willingness to switch to a bidet as a more sustainable and effective alternative. Through a 10 week Instagram campaign, we designed i) comic strips featuring our mascot, Biddy to encourage discussions surrounding toilet habits and ii) infographics that provide bite-sized information. 76% out of 25 followers have expressed positive interest in exploring the use of bidet or have already begun incorporating it into their daily lives. As a result, our engaging storyline paired with educational graphics have proved to be effective in raising awareness of the bidet as a sustainable alternative to toilet paper.

Air-conditioning is widely used in Singapore due to the year-long hot weather. However, aircon consumption requires a large amount of energy and is the second highest source of greenhouse gas emissions in Singapore. To tackle the lack of accessible substitutes to air-conditioning, our project aims to develop an alternative cooling solution to help nudge users to work in a warmer environment. We created an eco-friendly air-cooler using reusable materials, and reached out to youths via a i) 5-day challenge for user acceptance and ii) DIY workshop for experiential learning. Our prototype managed to achieve a temperature of 25.7˚C — a decrease of 2.7˚C. Participants of the 5-day challenge gave much positive feedback and expressed their willingness to continue using the product. Hence, the prototype is effective as an alternative sustainable cooling method and our users have successfully accepted working in non-air conditioned rooms through the 5-day challenge.

Due to the Covid-19 pandemic, the number of food deliveries spiked in the past year both globally and locally, resulting in an increase in food delivery trips and hence, an increase in carbon emissions and plastic wastes. Focusing on Ridge View Residential College, our project objective is apply the concept of food order coordination to reduce the carbon emission and plastic waste. The purpose is to reduce the number of separate food deliveries.

We created a Telegram channel and used the polling function to collect the individual orders from subscribers and combining them into one mass order. This resulted in the reduction of the number of deliveries and plastic bags and straws used. On average, we managed to reduce the carbon dioxide emissions by 1400g (including plastic bags) per mass delivery. Statistical results proved our project is effective in reducing carbon emission.

Infrequent plastic recycling in Singapore has resulted in large amounts of plastic wastage, adversely impacting the environment. An effective strategy is essential to promote plastic recycling. Our objective was to utilize these unwanted plastics to create a meaningful art piece, visually reminding RVRC residents of the repercussions of excessive plastic wastage, motivating them to recycle regularly. A visual approach, coupled with physical involvement generates lasting results.

We hosted a hands-on art workshop complemented with other implementations; i) a pre & post-workshop interview and survey, ii) designated plastic-collection booths, iii) creation of a collaborative artwork, and iv) Instagram page for publicity. Through interpretation of survey and interview results, 83% of our audience experienced increased motivation to recycle more often, which resulted in a 60% increase in plastic recyclables collected. Hence, the combination of our interactive art workshop, exhibition, and publicity proved effective in motivating residents to practice plastic recycling more frequently.

Many RVRC residents tend to use disposable containers when taking away from YIH canteen, which generates massive amounts of waste. Our objectives were to help them visualise the differences in the impacts of using disposable versus reusable containers and to persuade them to switch to the latter.

We designed a 30-minute interactive workshop that comprised a pre- and post-workshop and review survey, a presentation and a Kahoot quiz. We also put up posters and created a Telegram group to remind RVRC residents to bring their containers when taking away food. After the workshop, 30% of the 20 participants of our workshop started using their reusable containers at least 50% of the time when they take away food from YIH canteen. This shows our method had some positive effects in promoting the use of reusable containers to take away food.

Wastage of food in communal fridges has been a persistent issue in Ridge View Residential College (RVRC). With convenience for residents in mind, we implemented a multi-pronged approach of 1.) Food Sharing System (FSS), which comprised of labelling stickers to indicate food items that residents want to share and a telegram group chat to facilitate food sharing; 2.) Fridge-inventory mobile applications to remind residents of their food.

From our findings, the food waste mass in the treatment levels were on average consistently about 30% lower than that of the control levels. Around 60% of the residents from treatment levels made use of the FSS but were not as receptive to the fridge inventory application. Hence, we conclude that the FSS was an effective solution due to its convenience and practicality for reducing food waste from communal fridges, and has the potential to be sustainable with a few modifications.

Singapore generated 930,000 tonnes of plastics in 2019, of which only 4% was recycled (NEA, 2020). Liquid soap packaged in plastic bottles generates plastic waste which is not easily recycleable. Our project aims to encourage Singapore’s youths to switch from liquid soap to bar soaps to reduce plastic waste and carbon footprint. We delivered a 30-minute interactive workshop to address key concerns of bar soaps among the audience, a social media campaign to raise awareness on relevant issues, and a 3-week bar soap trial to help the audience form a habit of using bar soaps. After the workshop, participants’ misconceptions decreased by more than 80% decrease and 75% of the participants were willing to try out bar soaps. Our social media campaign and bar soap trial also received positive feedback. Hence, a combination of workshop, social media campaign and trial use proved effective in promoting bar soaps among Singapore youths.

Globally, the fashion industry is responsible for 10% of global carbon emissions (UN Environment, 2019). In Singapore, 1 in 3 people throw away clothes after wearing them just once (Yougov, 2020). Our survey amongst youths (n=60) showed that 60% purchase clothes out of impulse. Our project aims to reduce clothing consumption by changing perceptions and purchasing habits amongst youths. We created an Instagram account to educate youths with regular posts highlighting impacts of fast fashion and tips to reduce buying. A series of hands-on activities over 21 days aimed to change perceptions on clothing consumption. Additionally, a workshop was conducted to educate on impulsive purchasing habits and promote sustainable clothing. 84% of our 238 instargam followers reported that they will reduce clothing consumption in future. 94% of our workshop participants reported that they will choose sustainable clothing in future. Hence, the awareness campaign was effective in changing youths’ perceptions towards clothing consumption and purchasing habits.

In 2019, 744,000 tons of food waste was generated in Singapore, with only 18 percent of it being recycled. This indicates that more than 500,000 tons of food waste was left unrecycled on a national level, making this a concerning issue. By leveraging on social media and a website, we wanted to reach out and teach creative ways to turn fruit waste into edible food products. We designed a website to showcase some of our recipes using fruit waste and an Instagram page to engage with the younger audience. Pre-and-post taste test surveys for our products were also deployed in order to ‘convince’ consumers to adopt these new habits. By tapping on youths and technology, many individuals are now aware of how they can do their part against fruit waste in Singapore.

With the rise of the Covid19 pandemic, hygiene has become a more significant issue for many countries aiming to limit the spread of the virus. Our objective is to evaluate the effectiveness of promoting desk sanitizers made of fruit peels. Our project uses zoom and in person workshops to allow us to share with participants advantages of using fruit peel sanitizers and assess their opinions and gather any concerns they may have. Results show that 63% of them are not aware of the fruit wastage problem but 74% of them are willing to try using the fruit peel sanitizers. Hence a combination of zoom workshops as well as blogs for RVRC residents might prove to be useful and alleviating their concerns and promoting environmentally friendly desk sanitizers.

Meat consumption generates a significant carbon footprint, accounting for 14.5% of global greenhouse emissions (FAO, 2020). This necessitates the search for alternative protein sources such as crickets as they are high in nutrition and environmentally sustainable. However, these are not widely accepted due to low awareness and aversion. We aim to increase the awareness and willingness in youth in accepting entomophagy. We created an Instagram page, sharing the nutritional and environmental benefits of entomophagy. Hands on workshops were conducted to enable participants to try out cricket flour products. After both workshops and our Instagram campaign, our surveys showed a 92.6% increase in awareness of the nutritional benefits and a 93.2% increase in willingness to consume cricket flour-based foods. Hence, the combination of our workshops and Instagram page has shown to be effective in increasing the awareness and willingness to consume cricket-based food amongst youth.

Showering contributes to the highest water consumption out of all daily activities in Singapore. Thus, strategically targeting to reduce water consumption via showers will aid water conservation immensely. Realizing that simply raising awareness is ineffectual in enacting changes in showering habits of RVRC residents, our objective was to develop an audio-visual reminder that actively alerts users to stop showering within a stipulated time. We installed a shower-alarm device that activates a combination of flashing LEDs and an alarm buzzer to serve as the audio-visual reminder. This was accompanied by i) pre- and post- implementation surveys; ii) Posters to raise awareness; iii) DIY Kit for users to build their own shower-alarm device. Within the 2 weeks of device implementation, the average shower duration of participating RVRC residents was reduced by 27.3%. Hence, utilising our device along with the physical/digital posters successfully influenced RVRC residents to reduce their shower duration.

Household food waste is a prevalent issue in Singapore, mainly generated from leftovers and expired food items (Liu, 2020). Similarly, food waste in RVRC stems from excess meal enhancements (perishable) and packaged food items (non-perishable) being discarded unconsumed (n = 73). Our project aims to reduce these categories of food waste. We installed a central collection point at two pantries, supported by a Telegram Bot and channel, for residents to share food in a timely manner instead of disposing it. Our pilot test conducted for 4 weeks successfully redirected over 90% of food items left at our station (n = 54). Residents identified convenience and anonymity of our digital platform as key factors that alleviated their initial hesitation towards food sharing. Given the high adoption rates and effectiveness of our solution, we aim to convince the college to adopt it long-term.

Inconvenience is a crucial factor in Singapore’s declining domestic recycling rate (NEA, 2019), with 82% of RVRC students (n=76) citing it as a reason for not recycling regularly (AY1920G20B, 2019). Our project aimed to address this by providing an opportunity for waste segregation, so as to enhance the recycling rate in the RVRC dining hall. We targeted the waste from grab-and-go items during the breakfast service. We installed separate recycling bins for drink cartons and sandwich packaging, over three weeks. This effort was supported by an awareness campaign targeted at the residents. We collected a total of 95 juice cartons and 78 plastic sandwich containers. Of the estimated 840 such recyclables generated from residents dining in, our project successfully diverted 173 (21%) of them. Hence, our placement of recycling bins in a suitable location, along with the publicity campaign, has indicated it as a successful strategy to increase recycling rates in the RVRC dining hall.

The increasing global trend in the consumption of bubble tea has led to an increase in the waste generated from used tea leaves. Our project attempted to mitigate this issue of waste by reusing tea leaves to craft sustainable scented candles. Our preliminary survey of RVRC students found that 69% (n = 57) of respondents were receptive to using scented candles made from upcycled used tea leaves. We collected used tea leaves from bubble tea shops in NUS to make scented candles and invited 40 RVRC students to use and test them. We gathered comparative feedback about the candles through surveys, and also interviewed selected students. 88% participants gave positive feedback about using our scented candles, which lasted an average of 12 hours each. We conclude that upcycling used tea leaves into scented candles, instead of throwing them, is a possible alternative that minimises the environmental impact of tea leaves.

Research indicates that sustainability education from a young age is associated with increased environmental consciousness in the future. Environmental footprint and Earth Overshoot Day are relatable measures of an individual’s impact on resource consumption, and we saw an opportunity to spread its awareness to primary school students. We designed and conducted a workshop highlighting ways for P5 students to understand, measure and reduce their individual environmental footprint. The workshop incorporated interactive components tailored specifically for the target age group. Our results indicated that 92% of the workshop participants displayed an enhanced understanding of individual resource consumption and its implications for “Earth Overshoot Day”. Participants also deemed the workshop contents to be relevant in integrating with their school sustainability education syllabus. The most important measure of the workshop impact was its effectiveness in rallying a change in the students’ daily lives, as documented by the students themselves.

Energy consumption has been increasing over the past years. 90% of Singaporeans have access to smartphones and switching to Energy Saving Mode (ESM) is would help to reduce energy usage. We aim to increase the number of Ridge View Residential College (RVRC) residents using ESM, raise awareness about its potential to save energy and reduce e-waste, and determine the most effective method in encouraging ESM usage.

We created a poster, video and telegram channel to educate and encourage more RVRC residents to adopt ESM. The effectiveness of our methods were quantified through a pre and post survey involving the same respondents. We also interviewed 18 individuals for their opinions on ESM. After implementation, we expect to see an increase in frequency and number of RVRC residents using ESM. Hence, a combination of our methods proved effective in increasing RVRC students’ ESM usage, with video being the most effective method.

In Singapore, only 4% of plastic is recycled (NEA, 2020), largely due to plastic contamination and inappropriate plastics in bins. Our project chose to focus on the latter. Our preliminary data showed that 81% (n=72) of RVRC residents were aware of proper recycling habits. However, our recycling bins contained large amount of unrecyclable materials, rendering items in the bins unrecyclable. Our solution aims to reduce inappropriate and non-recyclable plastics in our plastic recycling bins, which would in turn increase the success rate of plastic recycling in RVRC. We created a prototype bin which had a deterrence layer to reduce disposal of inappropriate plastics, and a filter that had a 98% success rate of retaining larger plastics, while eliminating smaller unrecyclable plastics. This was supplemented with posters with clear messages to remind people of recycling etiquette. Hence, we believe that our prototype can increase the number of recyclable batches of plastic.

Meat consumption has been normalized in Singaporean youths as they consume up to three to five times more meat than is environmentally sustainable. This creates a significant carbon footprint. Studies have shown that nudging is an effective way towards behavioral change especially when combined with other informational tools. As such, we embarked on a social media campaign and developed a mobile application to function as tools to nudge students towards pursuing meat-reduced diets in a seamless and sustainable manner.

Our mobile application mainly includes i) nearest vegetarian stalls locator ii) push notifications iii) nutritional tracker iv) vegetarian recipes recommendation. With the use of mobile application and social media platform, focus group participants expressed greater interest and ease in pursuing meat-reduced alternatives. Hence, nudging students through the use of mobile application and social media platform proved effective in changing students’ behaviors towards meat-reduced diet.

COVID-19 has made masks an integral part of life. High usage of single use disposal masks led to an alarming rate of disposal, leading to land and water pollution and affecting ecosystems. Our group aims to educate youths on the detrimental environmental impacts of using disposable masks and encourage usage of reusable masks by teaching them a fast and easy method of making their own reusable masks.

We started an Instagram campaign to post educational infographics and organised both physical and Instagram live workshops to raise awareness of the issue and teach them how to make reusable masks. Our workshop survey showed that 83.4% of respondents had an increased understanding of harmful effects of reusable masks and continued to make reusable masks after the workshop. Hence our Instagram campaign and workshops have been effective in altering youths’ behaviours to become more environmentally conscious.

Undergarments and masks are daily necessities. The high usage and disposal rates of these two items bring about consequences to the environment. Our group seeks to educate residents on the adverse impacts of bra and mask disposal and empower them to repurpose unwanted bras into reusable bra masks. Essentially, we hope to push the boundaries of conventional ways of upcycling.

We designed a 30-minute focus group discussion comprising (1) a pre-and post-discussion survey, (2) a time-lapse video, and (3) a discussion on the consequences of bra and mask disposal. We also created an Instagram page for further outreach. Through our discussion session, 76% of attendees were more willing to partake in upcycling efforts in the future, and 80% of attendees claimed to have a heightened awareness of the environmental consequences. Hence, a focus group discussion is effective in achieving our objectives.

Plastic consumption is a pervasive issue in Singapore, with the use of plastic bags being deeply ingrained in the daily lives of many Singaporean households. As such, we aim to promote upcycling as a means of reducing plastic consumption. We will do this through a public awareness campaign, to raise awareness on the issue and help them take their first step in upcycling. Our campaign has three phases – Social media posts to appeal to our target audience, educational workshops on upcycling old clothes to tote bags as a plastic alternative, and finally a pilot study to gauge the effectiveness of our campaign. Educational workshops were able to promote upcycling as 80% of participants reported knowing how to upcycle their unwanted t-shirts after going through the workshop. Hence the use of hands-on workshop and video tutorials effectively aid in promoting a “pro-upcycling” mindset thus reducing plastic bag usage among students.

Academic Advisor: Ms. Sadaf Ansari

The e-commerce market has been growing globally, resulting in increased use of plastic packaging such as poly-mailers. In Singapore, poly-mailers end up in the waste-stream as they are not recycled. Our project addressed this issue by ‘closing the loop’ – collecting used poly-mailers and extending their lifespan as packaging materials through reuse. First we identified and set-up collection points in RVRC, and then we created an educational video to raise awareness on the proper steps to collect poly-mailers. To ‘close the loop’, we collaborated with an external partner for the reuse of the collected poly-mailers. Over a four-week implementation span, 87 poly-mailers were collected; which equates to more than 50% of the residents who had ecommerce packages delivered during this period. Therefore, our project has successfully tested the feasibility of a ‘collect-to-reuse’ solution to divert used poly-mailers away from the waste stream.

The long-term environmental impacts of single-use plastic, coupled with Singapore’s limited landfill capacity, highlight the urgent need to reduce plastic waste. For RVRC students, one simple way to mitigate this problem is to use lunchboxes instead of single-use plastic containers when doing takeaway. However, our preliminary survey indicated that most students do not adopt this solution due to inconvenience of washing the lunchboxes by hand. Our project addressed this problem by designing and testing a dishwasher prototype as a more convenient alternative. First, we measured the prototype’s effectiveness based on three key design criteria: hygiene, time required to wash, and water consumption. After making required design adjustments, we invited RVRC residents to test our prototype. Based on the results collected during the implementation phase, we found that our prototype was effective in all three criteria, and was also identified by residents as a more convenient alternative to wash reusable lunchboxes by hand.

The proliferation of ecommerce has contributed directly to an increasing trend in packaging waste and its resulting water and carbon emissions. Given that RVRC residents do not reuse ecommerce cardboard boxes, our objective was to implement a two-part system to encourage its diversion away from the waste/recycle stream, into the reuse stream. First, we set up collection points at carefully chosen locations. We conducted a poster and digital publicity campaign to raise awareness about our initiative, with a focus on Tuesday and Thursday – parcel collection days. Within 3 weeks, we collected more than 7kg of reusable cardboard boxes. For the second part of our project , we established a collaboration with an external partner. The collected ecommerce cardboard boxes were handed over to them for reuse. Our project results demonstrate that a significant number of ecommerce cardboard boxes in RVRC can be successfully redirected towards reuse, thereby minimising their environmental footprint.

Singapore is facing a rising demand for single-use drink containers. The lifespan of these items could be lengthened to reduce consumption of other ready-made products. Our preliminary survey results (n=108) indicated that most students (65%) consumed drinks from these single use containers multiple times a week and do not dispose them properly. Another survey was conducted to gather opinions about glass repurposing. Majority found our repurposed glass product attractive. Hence, our objective is to raise awareness of upcycling these single use drink containers among NUS students. We designed a website and a 40-min online workshop with surveys. During this workshop we engaged 35 NUS students to raise awareness about upcycling single use drink containers. The results indicated that majority of the students found the workshop effective in raising awareness about upcycling. Hence, our interactive workshop, website and repurposed product display proved effective in raising awareness about upcycling among NUS students.

Using store-bought dish soap could harm the environment in various ways, ranging from plastic waste from the bottles to deforestation caused by the production of palm oil, which is the soap’s main ingredients. An environmentally friendlier alternative would be to ferment fruit waste in order to make an enzyme-rich cleaner, which is suitable for daily use. Our project seeks to spread awareness through workshop and distribution of enzyme cleaner samples across RVRC’s pantries.

We conducted a 30-minute soap making workshop which consisted of a quiz and a post-workshop survey, demonstration of the enzyme cleaner as an environmentally friendlier alternative to commercial soap, as well as hands-on cleaner making activity. The fruit enzyme cleaner has been proven to be fun and easy to make during the workshop. Moreover, during the demonstration process, participants also agreed that the cleaner could effectively wash out oily dishes.

Singapore is experiencing an exponential surge in concentrations of microplastics in its natural environment, with pernicious concomitant ramifications on public health and marine life. We aim to raise greater awareness concerning the detriments of microplastics, in particular, microbeads in commonly used Personal Care Products (PCPs) and gauge the receptivity of RVRC residents to microbead-free alternatives.

We put up posters elucidating the deleterious effects of microplastics and conducted a giveaway for microbead-free DIY facial scrubs, complemented by informative e-brochures and videos expounding on the ease of making said scrubs. Pre- and post-giveaway surveys and a focus group discussion were subsequently conducted to determine receptivity to microbead-free alternatives. 90% of respondents had heightened awareness of microbeads in their PCPs while 97% were receptive to using microbead-free alternatives.

These awareness-raising initiatives were indubitably effective in helping students understand the detrimental effects of microbeads whilst promoting suitable microbead-free alternatives.

Our choice of food has a significant impact on the environment, especially in terms of the greenhouse gases emitted during production. However, our preliminary survey results showed that NUS students do not practice sustainable eating habits. Inspiration for our project was drawn from Duolingo’s leaderboard system as a form of motivation for increased performance. Therefore, we conducted a two-week observational study with a tracker and leaderboard system, to examine whether such a method of positive persuasion would encourage students to eat more sustainably. A scoring system was also designed to quantify the sustainability of common food ingredients. We updated participants daily on their scores for the day, to enable them to track their progress over the course of data collection. Our results concluded that the leaderboard system was successful in influencing more environmentally sustainable eating habits.

Water security is an essential issue in Singapore due to the energy-intensive desalination process, limited water resources and increasing demand. Given that rainwater is highly accessible in Singapore, our objective was to use rainwater as an alternative water source, specifically to mopping, thereby conserving and reducing consumption of potable water and energy in cleaning activities.

After identifying the most efficient location for rainwater harvesting, we designed and installed a rainwater harvester that filters, stores and dispenses rainwater. We executed a trial where cleaners would dispense the collected rainwater for mopping Block C’s ground floor. We interviewed the cleaners and OHS, and obtained positive responses. We found that the collected rainwater is of sufficient quality to ensure the cleanliness of the floor and conserves tap water simultaneously. Hence, we believe that using filtered rainwater is an effective and sustainable way for cleaning in the long run.

Contamination of plastic bottles is a significant issue in Singapore that prevents them from being recycled properly. Uncapping of plastic bottles and pouring away residual liquid within is crucial for reducing contamination. Gamification could motivate environmental protection, so we developed an interactive game board targeted at university students to promote the uncapping and emptying of bottles in a fun and engaging manner.

We designed an interactive Plinko board comprising of colourful elements and lights that users may drop their bottle caps into. The bottle cap would then randomly land in different reward zones. The board also directed players to recycle their plastic bottle bodies in the recycling bin directly besides it. With the presence of the Plinko board, the average recycling rate increased by 19.3%, and the average uncap rate increased significantly to 64.9%. Hence, gamification proves to be effective in promoting recycling and uncapping among RVRC residents.

The lack of natural resources makes sustainable living a priority in Singapore. However, youths remain ignorant and unmotivated towards sustainable living. Given that youths spend a significant amount of time on online platforms, our objective is to tap on their interest in games and social media to promote sustainable lifestyle through raising awareness, cultivating interest and providing incentives. We designed a competitive pet-raising game application that tracked the sustainability actions of 52 players and rewarded the players according to the reduction in their carbon footprint. We found that on average, 65% of players continued to play the game after 28 days, and that players showed greatest improvement in plastic bag refusal, with the tracking of electricity and water habits being the most popular. Hence, an engaging game application acting as a habit tracking device could encourage youths to lead sustainable lifestyles.

Recycling reduces the waste sent to landfills and conserves the natural resources as well as the environment. However, there is a lack of recycling habits in Singapore, where household recycling rates have hovered around 20 percent since 2005. Our objective is to promote recycling habits through bringing the idea of recycling closer to our target audience, the RVRC residents. We designed compartments to be placed into the room bins of residents, as well as a poster to educate residents on the correct recycling methods, so as to prevent recycling contamination. Before the project, 15.8% of the 19 participants recycle at least once a week. With the presence of the compartmentalization in the bins, 78.9% of them recycle at least once a week. As such, the presence of the compartmentalization of the bins, along with the educational poster on recycling contamination, has been effective in promoting the right recycling habits.

Infographics broadly use appeal to pathos (the guilty conscience), logos (use of statistics) and herd mentality (social comparison), to communicate and persuade the readers. Although used extensively by agencies such as the Ministry of the Environment and Water Resources to encourage a more sustainable lifestyle, the effectiveness of these infographic is yet to be determined. Given the excessive use of disposable cups by patrons in NUS food and beverage outlets, which contributes to the 473 million disposable plastic items used yearly by Singapore, our project compared the effectiveness of pathos, logos and herd mentality appeal to raise awareness and promote patrons of Li-HO at YIH to bring their own cups (BYO), thereby reducing plastic wastage. We found that although the pathos appeal poster attracted more attention, the number of BYO patrons did not increase. This indicates the ineffectiveness of infographic to promote more environmentally sustainable behavior.

Singapore has high water consumption per capita and 45% of it comes from usage. 10% is from the water basins and 16% is from flushing toilets by volume. We aim to reduce the water usage in flushing toilets. Our objective was to make an effective product that recycles water basin greywater to flush toilets, with no changes to their toilet usage. We measured the ability of our product to save water by measuring the amount of time it took to empty our greywater tank and conducted a survey on the receptiveness of our product and supplemented it with a focus group discussion to obtain details on their opinions on our product. 95% of people were satisfied with the ability of our product to save water, 77% reported no changes to their toilet use and our product can save 32L per day. Thus, our product recycles greywater effectly and is convenient for the user.

Global temperatures are increasing and people are using more cooling devices to keep themselves comfortable, translating to increasing electricity usage. To target this, we constructed a sustainable alternative that people can use to conserve both energy and material resources. We collected recycled materials such as styrofoam boxes and plastic bottles to make our prototype. Coupled with a handheld fan and ice cubes, our air cooler lowers the temperature of the environment and cools the user. Other than measuring the room temperature, wind speed and humidity, we also conducted interviews (n = 16) to survey user experience and to investigate if RVRC residents will use our device. From the results gathered, we conclude that our air cooler was reasonably successful as a majority of respondents gave positive reviews and demonstrated a willingness to substitute conventional cooling devices with our prototype (68.8% of respondents).

Proper electronic waste (e-waste) management is one of Singapore’s main priorities, given the rising generation of e-waste and its harmful effects on the environment. Teenagers aged 13-17 lack knowledge on proper e-waste management but are highly exposed to electronic devices. Our objective is to develop a game kit to educate teenagers on managing e-waste responsibly in fun yet effective way. We designed a game kit consisting of a card game and a lesson plan. The gameplay is followed by a facilitated discussion guided by the lesson plan, which aims to further increase understanding of responsible e-waste management. To determine the effectiveness of our card game, we conducted pre-game and post-game surveys on a sample of teenagers. A 40% increase in correct answers was observed in the post-game survey. Therefore, the combination of the card game and lesson plan proved effective in educating teenagers to manage e-waste responsibly.

Food waste due to cosmetic filtering of ‘ugly foods’ – misshapen or bruised produce, has increased the annual total food waste in Singapore from 606,100 tonnes in 2009 to 763,100 tonnes in 2018 (NEA, 2018). According to the Electrolux Survey (2019), 25% customers do not pick ugly produce. Our survey of NUS students (n=55) identified price as a key factor, in line with the Electrolux Survey results – nearly 50% respondents were willing to purchase cheaper priced ugly foods. Our project objective was to test these findings. We set-up a booth in NUS to sell normal and ugly bananas, priced differentially. Data collected from two days of sale found that 56% customers (n=60) purchased ugly bananas. 90% customers also indicated that they would purchase ugly foods from other sources at discounted prices. Our findings confirm that lower prices can incentive consumers to purchase ugly foods, and mitigate the problem of food waste.

The rising trend in bubble-tea consumption has contributed to increased use of single-use plastic cups. The Singapore Environment Council found that Singapore uses 473 million kg of single-use plastics (2018). Our survey of RVRC students (n = 135) indicated that 62% drink at least one cup of bubble-tea daily, and 7% drink more than 3 cups a day. Our project piloted a possible solution to reduce this plastic waste, with 12 volunteers from a sample of high-frequency bubble-tea drinkers. We provided them re-usable tumblers, tracked their use over 4 weeks, and collected qualitative feedback. Participants gave largely positive feedback about adopting a reusable tumbler, and data indicated a drop in their average weekly bubble-tea consumption by 28%. Both these results support our project objective, and indicate the need for an extensive study to determine if reusable tumblers can be adopted on a larger scale to limit the use of single-use plastics.

Increasingly, countries around the world are experiencing water stress (UNDP, 2019). Despite this, the average Singaporean uses 50% more water than in most developed cities (Biswas, 2017). Our project focused on the water wasted at RVRC push-taps – we measured that push-taps in the old block toilets have a flow time of 6 seconds, compared to the PUB recommendation of 3 seconds, causing an estimated waste of 5500 litres water in Blocks A and B. We tried to reduce the flow time by placing zip-ties at the circumference of the push-taps, limiting the taps’ depression. We measured the amount of water wasted at two toilets for one week without zip-ties and three weeks with zip-ties, and compared the data. Our findings indicate a saving of 2.7 litres of water per tap, proving the efficacy of the zip-ties in reducing water wastage. We have contacted NUS OES to consider this implementation for other locations on campus.

Singaporeans use 1.76 billion plastic items yearly, recycling only about 6% of it. This results in emission rates of over 100milllion kg of CO2. Hence, our project aims to reduce plastic consumption by providing a sustainable alternative to plastic detergent bottles and encourage the recycling of plastic bottles. We implemented i) a communal detergent dispenser in RVRC tower block laundry room; ii) a plastic bottle recycling programme allowing users to exchange plastic bottles for detergent from the dispenser; and iii) a campaign that educates RVRC residents about the issue of plastic waste and the carbon footprint from plastic production. With our dispenser, we save approximately 162 detergent bottles every semester, which adds up to 106kg of co2 savings a year, whilst incentivizing students to recycle and reduce plastic consumption usage. Hence, the combination of our detergent dispenser and recycling program effectively reduces RVRC’s carbon footprint and boosts recycling rates.

97% of local primary school students surveyed (n=60) lack knowledge about ecosystem resilience. Understanding ecosystem resilience is essential because a collapse of ecosystems will cause humans to lose access to natural resources. Cultivating awareness of ecosystem resilience early can nurture students to adopt more sustainable lifestyles. Games are a more engaging form of learning as compared to structured teaching. Hence, we hope to use a card game to teach primary school students ecosystem resilience. We designed a 1-hour session with 15 students consisting of i) a pre- and post-survey; ii) a focus group; and iii) our “Eco-Web” game. From our pre-and post-surveys, there is a five times increase in correct answers for the question asking for the definition of ecosystem resilience. This suggests that students have successfully learned the concept of ecosystem resilience. Hence, “Eco-Web” is useful in teaching primary school students the concept of ecosystem resilience.

Due to climate change, water resources are increasingly becoming scarce. In RVRC, where the concept of water sustainability is emphasized upon students. As such, the habit of conserving water must be cultivated within RVRC. With this in mind, we can reduce our water wastage in daily lives through the usage of the ShoWash Machine. Through our ShoWash Machine, water usage can be tracked and reduced accordingly. It also provides a more convenient way as compared to the manual shoe washing that requires people to bend down to scrub their shoes. With this in place, 66% of the water used in regular shoe washing can be saved and 74% of our respondents agreed that our project could save a lot of water. Hence, the ShoWash Machine is shown to help reduce water wastage.

Academic Advisor: Ms. Sadaf Ansari

The overall domestic recycling rate in Singapore is 20% (MEWR, 2018), and only 60% households recycle their trash on a regular basis (NEA, 2019). Our survey found that recycling participation in RVRC residents (n=50) is 30% – less than half of the national recycling rate, and that inconvenience and lack of recycling knowledge are the primary causes. Furthermore, during a spot check, we found 4 of 9 recycling bins contaminated. Our project aimed to tackle these interconnected problems by testing a specially designed compartmentalised bin, with visual aids to allow easy sorting of trash. Our bin re-design was based on the residents’ survey feedback. The re-designed bins were provided to 12 randomly selected residents, and their use was tracked over three weeks to collect data on recycling. Our findings indicate a significant increase in the rate of recycling and a decrease in rate of contamination among participants, showing the effectiveness of the newly designed bin.

Fast fashion is one of the most polluting industrial sectors (Anguelov, 2015). Yet, 25% Singaporeans throw away more than ten items of clothing and awareness of sustainable fashion brands is low (YouGov, 2017). Our survey results for NUS students indicated that 80% respondents (n=73) were willing to switch to more sustainable fashion brands, but 75% lacked knowledge. Our project had two aims – to identify the critical metrics for measuring fashion sustainability, and to bridge the knowledge gap about sustainable alternatives among university students using Instagram. Fabrics and dye were identified as the two strongest markers of fashion sustainability. Using t-tests and multiple linear regression to analyse data, our results indicate that we successfully raised the awareness of fast fashion alternatives. More specifically, knowledge of fabrics and dye emerged as key predictors for increased awareness. Moving forward, we aim to further build the Instagram channel for NUS, and use it to start a sustainable fashion interest group in RVRC.

Singapore generated 949,300 tonnes of plastic in 2019, of which only 4% was recycled (NEA, 2019). Given the significantly low percentage of recycling, our project tackled the root of the problem – use of single-use plastics. The objective was to test receptiveness to a weekly ‘plastics-free day’ at the RVRC Dining Hall, that otherwise uses 200 plastic-pieces daily on average at the Grab-and-Go counters. We collaborated with the caterers to publicise and implement the project across four weeks, to reduce the use of plastics in the Breakfast service for items such as sandwich boxes, juice cups and plastic bags. Results from our field research and survey responses showed that most respondents were supportive towards, and even wanted the initiative to happen more frequently. Hence, we can conclude that the project serves as a successful feasibility study and provides a good start to implementing similar initiatives in future.

Repurposing is essential to reduce the amount of waste put into landfills and the amount of virgin materials used to make new items. Our objectives were to raise awareness and initiate a repurposing habit through engaging participants in a hands-on activity of creating exfoliators from spent coffee grounds.We created a general survey to gauge the current perception of repurposing within the RVRC community and to validate our research. We also ran 30-minute long interactive workshops compromising of a pre-survey, a sharing session on repurposing and a post-survey. Lastly, we had a follow-up with the participants from our focus groups to check for any change in repurposing habits. Through this process, we saw a growth of awareness in 95% of our participants. However, only 25% of our participants showed signs of adopting repurposing habits. In conclusion, a one time-off intervention can raise awareness but remains insufficient in inculcating a new habit.

Food security is essential in Singapore as less than 10% of its food is locally produced (Tortajada, 2016). Bread, amongst other staples, is most commonly discarded (Ng, 2017). Since large quantities of perishable bread are served in the Dining Hall, we targeted bread wastage. Repurposing is innovative in transforming potential waste into something useful, so our objective is to educate and change mindsets on the consumption of leftover bread.

A three-pronged approach comprising i) baking workshops with pre and post-workshop surveys, ii) dissemination of infographics including recipes and debunking myths about leftover bread through communication platforms and iii) collaboration with the Dining Hall to transfer leftover bread from breakfast to pantries was adopted. Through this approach, 63% of the leftover bread was consumed. The amalgamation of numerous baking workshops, dissemination of recipes and placement of breakfast’s bread in the pantries proved effective in reducing bread wastage in the Dining Hall.

Waste management is a priority in Singapore because of the limited space in Semakau landfill, predicted to be full by 2025 (MEWR, 2019). However, 70% of Singapore consumers order food delivery at least once a month (Lim, 2019), with 49% consumers aged 18-34 years (Cheng, 2018). Similarly, our survey results found about 77% of RVRC students (n=100) order supper more than once a week. Our project aims to test a solution to reduce the food packaging waste by providing an alternative in-house supper option. During our widely publicised supper event offering affordable snacks for purchase, students were required to bring their own container to reduce plastic waste. Data collected from the event indicates that 94% of RVRC residents preferred to order in-house supper as compared to other supper alternatives. Our findings have been shared with the incoming student council for adoption the next academic year, to reduce RVRC’s collective waste footprint.

In 2018, Singapore generated almost 950,000 tonnes of plastic waste (NEA, 2019). Pulau Semakau landfill is projected to be filled up by 2035 (MEWR, 2020) at this rate, and reducing single-use plastic waste is therefore crucial. Our project objective was to test the receptivity to providing dine-in customers the option of reusable cups, at NUS foodcourts. We collaborated with the Fine Food drink stall vendor in UTown, for conducting a two-week pilot. Reusable cup uptake numbers were tracked from the vendor’s billing. Data was also collected from consumers using surveys before and after implementation. The calculated break-even point was achieved within 2 weeks of the pilot; the environmental impact of 75 reusable cups was balanced by the disposable cups saved. We have shared our findings with NUS OES, that clearly demonstrate that providing reusable cups for dine-in customers at food courts can be adopted as a sustainable solution to reduce single-use plastic waste.

Single-use plastics, justified by the industry due to perceived effectiveness in extending the shelf-life of food (Schweitzer, 2018), cause global environmental problems due to wasteful and small-format packaging, and low recycling rates (IEEP, 2019), and in Singapore too (Hwee Min, 2019). To address this concern, we operated a Zero-Waste Store in NUS. Our project serves as a feasibility study and pilot test for a store to be implemented in collaboration with NUS SAVE. Prior to execution, a sensing survey (n=150) was conducted to gauge receptiveness and identify popular packaged food items. Sourced from zero-waste suppliers, our store operated for a week at a campus location with high foot traffic, implemented zero-waste packaging, and charged wholesale pricing. In a post-purchase survey (n=110), 97% customers indicated willingness to buy from zero-waste stores on campus, and 91% mentioned that the store increased their awareness of food packaging waste. These findings, and high volume of sales, indicate high receptiveness towards the implementation of zero-waste stores in NUS.

The textile industry is one of the top three contributors to carbon emission in the world. Based on our survey done on 31 undergraduates, 64.5 % of our respondents wear fast fashion items and own at least 3 pieces shirts from NUS events. Most of these were disposed of after being worn a few times. Our project seeks to raise awareness of textile wastage in undergraduates through workshops and social media. We conducted interactive upcycling workshops for 31 undergraduates and launched a social media campaign on Instagram encouraging undergraduates to upcycle their worn clothing and reduce disposal. After attending our workshops, 92.3% of our participants will continue to upcycle clothes and 90.3% of our Instagram followers state that they know two ways to upcycle. This suggests that the combination of workshop and social media is effective in educating undergraduates on upcycling.

Despite an abundance of green spaces locally, there is a growing disconnect between youths and Mother Nature. To enhance their attitudes towards nature and wildlife, it is critical to educate youths with knowledge that will pique their interest and appreciation for the environment. This objective was achieved by directly immersing youths amidst Nature with the implementation of experiential learning. Our group designed a birdwatching tour comprising of pre- and post-tour surveys, a digital e-book containing unique features of birds and plants, and a Kahoot quiz. After the tour, Instagram and YouTube were utilised to sustain participants’ interest. Data analysis of our survey results have shown a general improvement in comfort, attitudes and knowledge level for the participants post-tour. Therefore, by conducting a guided tour which placed emphasis on experiential learning and through supplementation with social media platforms, our project achieved success in increasing participants’ interest for nature and wildlife.

Plastic wastage is a perennial problem throughout the world. In Singapore, of the 1.76 billion of plastic items used, only 6% are recycled. As students staying on campus, we wanted to understand the extend of plastic wastage coming from our soap bottles and packaging, as well as find out the feasibility of implementing a refillery system in RVRC. We executed our plan in two phases i) voluntary survey and ii) a series of soap distribution trials. Our voluntary survey found that 68% of RVRC students bought new soap bottles upon finishing, and that 500ml of soap lasted 1.5 months on average. Furthermore, our series of trials saw a total number of 112 RVRC students collecting from our distribution. Therefore, we find that our execution had achieved adequate results in proving RVRC students’ susceptibility to a soap refillery.

Urbanisation causes decline in suitable bee habitats, threatening the bee population essential to our ecosystem. Our objective is to improve the quality of bee habitats within NUS by implementing artificial nesting sites. Field surveys were carried out around NUS, where we observed and noted the bee species around the area. This is followed by the construction of artificial nesting sites using bamboo sticks and drilled-out wooden planks. Weekly checks were conducted on these bee “hotels” for the presence of bee activity. 12 bees in 3 families found through observation only, some bees might not have been spotted. Currently, no bees have been observed to use our bee “hotels”. Possible reasons include bad weather, lack of time and other animals such as spiders nesting in the bee hotels. Still, through our survey, we can conclude that urban structures are regularly used by Singapore’s solitary bees as nest sites.

A minor change in the average Singaporean’s diet would be sufficient to ensure long-term food sustainability (Deloitte & A*Star, 2019). This project attempted to raise NUS students’ awareness of the impacts of their food choices through a scenario-based web game. The game includes familiar and relatable choices from various canteens in NUS. These choices were assigned scores based on LCA and users were informed of their environmental consequences. A sample size of 60 was chosen, out of which 30 students played the game and 30 acted as a control. A test was then administered to gauge the awareness of the different groups, with the experimental group scoring 17% higher. A hypothesis test was used to determine the statistical validity of the test results. The test showed there was a significant improvement in test scores of users who played the game (95% Confidence), confirming the effectiveness of our implementation.

Although Singapore has a relatively high recycling rate, most of this plastic waste does not end up being recycled due to contamination. Bad recycling practices will end up piling plastics in landfills, which will soon run out of space. It was found that the majority of RVRC students cited inconvenience as the reason why they do not wash their plastic bottles. Our project objective was to build a prototype that helps to wash plastic bottles efficiently. We have designed and constructed a prototype that includes a rinser that washes plastic bottles within seconds. Using our prototype, 96.8% of RVRC survey respondents found it more convenient to wash their plastic bottles and increase in 50.6% of the respondents who are willing always to wash their plastic bottles before recycling. Hence, proper equipment that enhances convenience proved effective in encouraging people to recycle correctly, reducing the amount of recyclables being disposed of as wastes due to contamination.

Plastic waste is a pressing issue in Singapore due to a shortage of landfill space, with disposable plastic packaging of cosmetic samples being a significant contributor to plastic waste. Thus, we aimed to develop a sustainable alternative to the packaging of sample products to reduce plastic waste, measured through stakeholders’ receptivity of the sustainable alternative and consumer satisfaction and product feasibility. We used a preliminary survey to collect insights and consumer preferences, conducted two rounds of focus group discussions and multiple interviews with stakeholders to measure receptiveness and satisfaction. The high overall receptiveness of our prototype was 82.3% in the FGD and our prototype had potential development as feedback from all five of our industry interviewees. Given the estimated reduction in carbon emission as well as high consumer receptivity, these prove that SAMpills will be effective in reducing plastic waste if used by the cosmetic industry.

Renewable energy sources are underutilised in RVRC. Based on an interview with OHS, we concluded that the root causes of the aforementioned situation are inaccessibility to renewable resources and the lack of awareness among the residents. Thus, it is important for us to promote the use of renewable energy sources in RVRC. Study lamps are commonly used amongst the residents, therefore our objective was to create a sustainable and environmental-friendly study lamp to raise awareness among RVRC residents. We conducted a survey and focus group to assess whether RVRC residents would be receptive to using our product and encourage them to consider solar energy alternatives for appliances. We conducted the focus group to corroborate the findings of our survey results. 87.1% of the surveyed residents were willing to switch to a more sustainable study lamp. Thus, it shows that RVRC community is receptive of LumiSolaris.

Most local universities emphasize sustainability education, but students may not be inclined to voice their ideas or discuss sustainability during lessons. Collaborative game-based learning can supplement the current education model to prompt students to have sustainability-related discussions in a fun and engaging manner. We conducted our research by surveying university sustainability educators to collate professional feedback on collaborative game-based learning and playing our sustainability card game, 99 Problems, with university students who had enrolled in sustainability modules. Pre- and post-surveys were conducted to collate students’ opinions on the game and current sustainability education. 73% of students shared that they would prefer playing our game both in and out of the classroom as they felt more inclined to engage in sustainability discussion after gameplay. Hence, an interactive card game that promotes discussions and sharing of ideas proved to be effective in enhancing the students’ experience in learning about sustainability.

Reducing food wastage is a priority in Singapore due to a lack of landfill space, and the upcycling of spent coffee grounds help to alleviate this. Our objective is to create a whiteboard duster casing by mixing both waste coffee grounds and waste polylactic acid (PLA) to upcycle spent coffee grounds, ultimately reducing the amount of waste entering the landfill. We designed a new whiteboard duster to replace traditional whiteboard dusters and invited students to focus group discussions to i) test the product and ii) to obtain feedback and insights of the manufacturing process, and iii) to see their willingness to use our dusters instead of traditional dusters. Our product was complimented for being user friendly and sustainable, as the calculated carbon footprint for our duster is less than that of the original duster. Hence our product, if implemented widely, can help reduce food waste while being sustainable.

We conducted a 2-day workshop titled “Let’s eat, Kids!” for preschoolers aged 5-6 years old, introducing them to food wastage. Each age group attended the workshop on different days. Before conducting the workshop, we visited the Childcare Centre to gather more information and find out more about the food wastage situation there. Firstly, we interviewed the teachers to know more about the students’ eating habits and learning activities. Next, we conducted focus group discussions with the students to know more about their knowledge about food waste. After we collected the data, we made a storybook, interactive booklets, puppets, puzzles, colouring and stickers for our workshop. We conducted a pre-and-post workshop focus group discussion with the students to ensure that our objectives are met. To measure the effectiveness of our project, we conducted interviews with the teachers before and after the workshop on the amount of food wasted.

The study lamps are not fully sustainable for the environment. The electrical energy used by the lamps is generated from fossil fuels which are non-renewable sources of energy. As fossil fuels are limited resources on earth, it may deplete even more in the future as the demand for electricity increases. Hence, our project objective is to transform the energy use of the lamps to become more efficient. We designed a new lamp that will reuse light and heat energy from the lamp to promote plant growth. We experimented and found that there is a 10 grams increase in the mass of the plant in the presence of the lamp as compared to without the lamp. We have conducted focus groups to receive further feedback to improve the lamp. We aim to encourage the use of sustainable lamps within the campus as even small efforts contribute to protecting the environment.

Environmental initiatives are centered around younger populations, and the elderly are marginalized. They are an equally important sub-population, with lifestyles involving numerous interactions with others. Our project addresses the lack of environmental stewardship provided to the elderly by organizing workshops to raise awareness of sustainability and promoting ways to improve their lifestyles. We researched elderly pedagogy to create an effective lesson plan. To evaluate our project, we created pre/post surveys to understand the conceptions of environmental sustainability, ensuring the elderly can contextualize our lessons to their daily lives. The project is carried on a pilot sample, and we sought advice from teachers at elderly centers about the efficacy of our lesson content. Comparing the surveys, that the elderly reported a greater understanding of environmental sustainability, and were able to contextualize our lesson to our lives. Feedback from the surveys highlighted that our lesson content was engaging. Our lessons can be implemented on a broader scale, where various elderly educators can apply our ‘textbook’ material to conduct lessons, using it as an independent model.

The study lamps are not fully sustainable for the environment. The electrical energy used by Ridge View Residential College (RVRC) prides itself on its natural beauty and emphasis on sustainability. However, stakeholders considered the barren slope at Block-E as unaesthetic and unutilized (dead-space). Furthermore, there was a lack of biodiversity in the area. Hydroponics provided a good solution for the uncultivable land. Growing plants would increase biodiversity and improve the dead-space of the slope concurrently. Our team designed and installed a NFT hydroponics system, where we successfully sprouted two varieties of lettuce. We evaluated the system through a focus group. Participants were agreeable that the project met the objectives spelt out, and that they would like to see more such systems around RVRC. Not only did biodiversity at the slope increase by growing lettuces, insects such as bees were also drawn to the plants. Our system proved to be unique way to improve biodiversity, while simultaneously tackling the issue of dead-space in RVRC.

There is a necessity to tackle clothing wastage generated by fast fashion in Singapore due to low recycling rates and our inability to accommodate future textile waste. Our objectives were to engage, educate and encourage youths to purchase second-hand clothing instead of first-hand, such that unwanted clothes will not end up as excess clothing wastage.

Following the AMO (Ability, Motivation, Opportunity) framework of changing behavior, we designed a 3-step approach comprising i) an interactive face-to-face survey; ii) using Instagram as an educational platform; and iii) a second-hand clothes bazaar. After the bazaar, our 61 participants displayed a 46.4% increase in willingness to incorporate second-hand clothing into their wardrobe.Hence, our 3-step approach of motivating youths through our interactive survey, giving them the ability to access second-hand clothing and an opportunity to purchase, proved effective in changing the purchasing behavior of youths.

Human-wildlife encounters do occur in RVRC due to our proximity to the secondary forest. Residents are largely unaware of measures to take when encountering wildlife in distress. Our project employed an engaging video platform to education residents on proper procedures to take when encountering such wildlife, allowing for the easy proliferation of information throughout RVRC. It aims to inculcate the mindset of ensuring the well-being of animals, instead of treating them as pests to be exterminated. We also designed a refresher workshop that would reinforce Resident Assistants (RAs) and Senior Retention Program (SRP) students with the knowledge on responding to such encounters. We found that a majority of our respondents learnt response measures and gained an appreciation for wildlife from the video and workshop. Thus, the combination of the video platform and refresher workshop to key personnel was effective in equipping residents with proper wildlife encounter measures.

A woman typically produces 200kg of plastic waste, due to the usage of disposable menstrual products, in her lifetime (London Assembly, 2018). However, this issue was rarely discussed due to stigma. Our project aims to increase awareness and inform young women on sustainable menstrual products, and hope to nudge more into using them. We adopted a two-pronged approach to engage our audience. In the direct approach, we hosted focus groups to provide an avenue to share information and for women to clarify their concerns. We also launched an Instagram campaign to generate interest and engage a wider audience. In both approaches, we work to inform the audience and provide information on sustainable alternatives.

Our results show that our focus group participants gained a 60% increase in knowledge of menstrual products. There were also 25 purchases of sustainable products among our 184  Instagram followers. These suggest that our approach is effective.

Ethical consumerism refers to the purchase of products that are ethically produced and are not harmful to the environment and society. Unethical products such as fast fashion and palm oil products make their consumer part of the environmental impact. Our survey showed that youth are significant consumers. We hope to design an educational game which teaches the consequences of unethical consumerism. This is a 30-minute interactive game that immerses the players/students in a storyline where they will make decisions that will directly impact the survival of our Earth, as well as educating them on affairs related to sustainability issues. Upon comparison with our control group (Lecture), the participants of the game gave more positive responses on how our game increased their awareness and knowledge about the given topic, as well as how the gameplay, storyline and immediate feedback were effective in their learning, which indicates that this project is effective.

Food waste constitutes one of the biggest waste streams in Singapore, generating 763,000 tonnes of waste in 2018. This includes processing waste such as brewer’s spent grain (BSG) from beer production. While other countries are able to repurpose BSG into animal feed, our survey of local breweries found that BSG was thrown away due to Singapore’s lack of animal farms. We also found that consumers in the youth category do not know processing food waste can be repurposed.

Our project aims to educate youths about repurposed food waste using BSG through a taste-test and an Instagram campaign. 74% (n=51) of respondents showed improved knowledge of BSG after the taste-test and 88% (n=51) had increased awareness of using repurposed food waste in food preparation. A direct hands-on approach and the use of social media has proved effective in engaging youths on the issue of repurposed food waste.

Singapore’s climate action plan (2019) states that transport accounts for 16% of the total greenhouse gas emissions in 2014. Private car services such as Grab now have at least 26,000 more vehicles than taxis(ST 2017). Our project aims to reduce its impact by encouraging carpooling in residential college students when they hire Grab cars. We used a Telegram bot that group students via ride-hailing services and connect students that are intending to travel to the same location to carpool together. This can reduce emission by 75% as compared to when the ride was taken alone. With the feedback from 60 RVRC students, 93.5% of the students indicated that they will use our telegram bot service again. Hence, we are confident that the implementation of our platform is well welcomed within the RVRC community and will definitely lower carbon emissions.

In the Zero Waste Masterplan introduced by MEWR, electronic waste (e-waste) was identified as one of 3 high-volume waste streams, with only 6% of e-waste generated in Singapore recycled and the rest improperly discarded. As e-waste is not generated regularly, we investigated if a once-off collection drive in NUS would be more effective than bins placed at certain locations permanently. We also assessed the outreach effectiveness of various targeted publicity method for the collection drive. We held two collection drives and surveyed participants on the reach of different publicity method. We found that emails were the most effective, with 85.7% of donors indicating that they came down due to the emails sent. After two days of collection, we amassed 287kg of e-waste, more than the annual average amount collected by one RENEW bin. This shows that once-off collection drives is more effective than the regular e-waste recycling bins on campus.

With publicity in mind and college reputation at stake, the environmental impact generated by one-off events such as NUS open-day is often neglected by stakeholders, causing unnecessary use of resources and waste. We aim to reduce this waste in future open-days by implementing an electronic platform alongside physical open day, giving the audience a choice on the medium they wish to engage with. We analysed the effectiveness of RVRC e-open day 2020 and implemented a live chat in addition to other measures taken by the official e-open day team. By analysing quantitative and qualitative data, the e-open day measures were found to be successful in conveying information that our target audience wanted. This is supported by 20 interviewees. However, due to limited outreach and publicity, e-open day was less known to the public as compared to physical open day. Therefore e-open day cannot completely substitute physical open day.

Cutting down on the usage of heating systems for laundry can reduce Singapore’s carbon footprint by eliminating the unnecessary production of carbon dioxide. Our preliminary survey indicated that many RVRC students use hot water for laundry due to misconceptions and the lack of knowledge regarding cold wash. Thus, the objective of our project is to encourage RVRC students to actively switch to cold-wash through an educational approach. Our campaign consisted of i) a life-sized exhibit and colour-coding system and ii) a sticker labelling system to measure students’ choices over a two week period. We conducted pre and post exhibit surveys and followed up with a group of students to complement the observational studies. We found that the proportion of students who use cold wash increased by approximately 30%. Hence, education paired with the constant reminders prove effective in encouraging RVRC students to switch to cold wash for laundry.

Fast fashion is a global problem; clothes are being purchased and discarded in record quantities, resulting in a build-up of textile waste and encouraging unethical garment production practices (Morgan & Birtwistle, 2009). Our project aimed to use digital technology to raise awareness on the environmental consequences of fast fashion, and to create a platform for our target audience to take action. We created a Telegram channel where we posted curated information regarding environmental and social impacts of fast fashion. In parallel, we also coded and launched a Telegram bot as a platform for people to sell their unwanted clothes. Results from pre – and post-surveys indicate that channel subscribers benefited from increased awareness. Transaction data from the Telegram Bot indicated successful translation of this awareness into action for trading used clothes. Together, our two-pronged approach was effective in making generation Z Singaporeans more aware of environmental consequences of fast fashion and take action.

Despite the ease of composting, fruit waste is incinerated in Singapore. This breaks the nutrient cycle, leaving the loop open and ending the movement of valuable mineral nutrients (Elser and Bennet, 2011). Singaporeans consume 72 kg of fruits per person annually (Singapore Food Association, 2018), of which roughly 20% ends up as waste from fruit peels and cores. Information provided by the RVRC Office of Housing Services and the dining hall caterers indicated that students contribute to approximately 6000kg fruit waste each academic year. Our survey of RVRC residents (n=49) found that 52% were unaware of this problem and possible solutions. Our project aims to raise awareness and encourage residents to reconsider their fruit waste disposal habits. We conducted a workshop comprising of interactive games, informational videos and direct engagement. Data collected from the workshop indicated the success of our project in increasing awareness of the need to close the nutrient loop and to adopt alternatives to binning fruit waste.

Despite the fashion industry contributing 10% of global greenhouse gas emissions, one-third Singaporeans dispose clothing only worn once (YouGov, 2017). Our project targeted NUS students who belong to the age group that is the leading contributor to this problem. An initial survey (n=102) found that 95.5% respondents are unaware of the negative impacts of fast fashion. Our project has two aims, to increase awareness of the negative impacts of fast fashion, and to make known local sustainable alternatives. To achieve these, we produced and disseminated two videos to our target audience. Data was collected using pre and post-video surveys, to measure the effectiveness of our videos. Results indicated an increase in the perceived level of awareness by 30% about the negative consequences and alternatives of fast fashion. Our findings confirm that educational videos are an effective solution to disseminate information to teh youth and heighten their awareness of the consequences of fast fashion.

Plastics are amongst the top ten common pollutants in the world. Singapore uses an alarming 473 million disposable plastics annually, the majority being takeaway food containers (SEC, 2018). Within RVRC, our preliminary survey (n=63) showed that 90% of respondents frequently take-away food in single-use plastic bags. Hence, our project objective is to develop an alternative for plastic food packaging using biodegradable gelatine to reduce plastic consumption and, thus plastic waste. We conducted a focus group discussion with students and an interview with the caterer to gather feedback on how to improve the flexibility of our gelatin plastic and understand their receptivity towards our prototype. If implemented in the Dining Hall, it could potentially replace 150 plastic packagings a day, 900 packagings a week and 31,500 packagings a year. In this way, we could help reduce plastic packaging and the reliance on disposable plastics in RVRC.

Laundry dryers in RVRC and other residential colleges generate significant amounts of lint that end up being disposed of. To reduce the amount of lint being disposed of,our project aims to upcycle lint into a useful product (cardholders) that is frequently used by many RVRC residents. Additionally, we want to improve the user-friendliness and durability of our lint cardholders, which would ensure the sustainability of our product. We conducted two Focus Group Discussions (FGD) and post-discussion surveys to gather feedback from our users. The first FGD was to gather input on ways we could improve our lint cardholder prototype. The second FGD was to collect data on whether the previously-raised issues had been resolved. Almost all respondents have indicated a significant improvement since the first prototype. Hence, our project  shows that it is possible to reduce lint waste by upcycling it into a useful and sustainable everyday product.

The excessive usage of treated tap water in community gardens is not ideal since tap water treatment in Singapore is energy-intensive and consumes large quantities of chemicals and materials. The objective of the project is to provide community gardeners with a reliable, low cost and water-conservative rainwater harvesting system to complement or replace their existing water source. Our designed system could 1) integrate with the current roof drainage systems; 2) provide gardeners with easy access to high capacity water tanks; 3) filter collected water to allow usage in current irrigation systems. Our focus group, comprising community gardeners from Bukit Batok Cosy Garden, is receptive to the idea as our water collection system could sustain gardens for up to 1 week per full high capacity tank. Hence, we conclude that the construction of this system would act as a useful alternative water source for community gardens.

Singapore produces around 60,000 tonnes of e-waste a year (NEA 2018), making e-waste disposal a significant issue. Our survey also found that most youths are unaware of what constitutes e-waste and its proper disposal procedures. Our project aims to use an educational board game to educate youths about e-waste and proposal disposal habits. The game was tested with 32 youths and compared their knowledge retention with a control group. Both pre-surveys and post-surveys were organized to quantify the increased knowledge on E-waste of our target audience. We found that youths who played the game scored an average of 71.7% for knowledge retention compared to the control group which scored 50%. This demonstrate the effectiveness of using board games to impart knowledge on sustainability issues such as e-waste usage and disposal.

One third of Singapore’s food waste is contributed by ugly food. This is attributed to Singaporeans’ misconceptions and lack of knowledge on these aesthetically unappealing foods. Aimed at educating youths on what defines ugly food and increasing accessibility to them, our project attempts to encourage youths to purchase ugly food, thereby reducing food wastage.

We conducted an exhibition and compiled a map of ugly food retailers. Our exhibition aims to increase knowledge about ugly food and where to access them, encouraging consumption. Our map enables NUS students to locate ugly food retailers near campus, making it easier for students to commit to purchasing ugly food. Up to 70% of those who attended our events have shown increased awareness and willingness to consume ugly food. From our data, increasing knowledge and accessibility of ugly food is an effective way of reducing ugly food waste problems in Singapore.

Microplastics (small plastic pieces less than 5mm) is a significant source of marine pollution. Brandon et al (2020) estimated that there is now 8.3 million pieces of microplastics per cubic meter of ocean water. Chemical additives of microplastics can release toxins which can harm marine life. They also cause bioaccumulation of toxins in humans, and can lead to health problems such as infertility and cancer. The Small Things Big Impact project aims to mitigate the environmental and human impacts of microplastic by raising awareness on the prevalence and impacts of microplastic and encouraging youths to consider environmentally friendly alternatives to facial washes containing microbeads. Through a series of workshops and social media campaign, the team managed to engage at least 60 youths in understanding this and to consider more sustainable facial product options.

In Singapore, a growing coffee market generates an increasing volume of spent coffee grounds (SCG). Our project aims to 1. establish the effectiveness of SCG to be re-purposed as body scrubs, potentially replacing environmentally harmful mircobeads; 2. encourage RVRC students to try making these body scrubs, hence extending the life cycle of SCG. We produced two types of body scrubs with SCG, and improved the first version based on trial and feedback provided by a focus group of 17 RVRC students. Thereafter, we conducted a workshop to pitch and distribute version two of the body scrubs to the focus group for testing again. The focus group rated the second version of the two scrubs as more effective (T-test: p=4.19×10-5 and p=1.09×10-8), and were open to making such scrubs on their own (Chi-squared test: p=2.06×10-5). Hence, focus group testing and a workshop proved effective in encouraging RVRC students to re-purpose SCG.

Proper recycling is essential to reduce resource use, but improper disposal of items such as disposable plastic cutlery, soiled food packaging and plastic packaging with foil into the local recycling bins has resulted in a staggering low 4% recycling rates of plastics (NEA,2018). Our project aims to increase awareness of proper recycling among Ridge View Residential College residents, and introduce the concept that recyclables are not trash, but have a purpose and afterlife. We replaced the plastic recycling bin with our self-designed transparent shelving system, which improved the visibility of what can be recycled and deter disposal of soiled items. We quantified the amount of plastic recycled pre and post implementation and surveyed the residents. Our results showed that although the total amount of plastics collected had decreased, the contamination had also reduced significantly, which would ultimately result in more clean plastic items being recycled.

Product life cycle thinking (LCT) by consumers could promote recycling of used products to minimise resource use, but the lack of awareness of LCT by Singapore consumers hinders policies to effect a circular economy. Our objective is to increase awareness of product LCT through engaging hands-on activities. We created a card game to educate players on the life-cycle of consumer goods, which can be used in workshops, classes or at home in a fun and enjoyable way. We held several workshops to play test our game with university students, and included a pre- and post- gameplay survey to evaluate game’s effectiveness. In our pre-gameplay survey, 62.5% of participants indicated little to no knowledge of the life-cycle of consumer waste products. Post game, 83.4% of participants indicated an increase in their knowledge of product LCT. Therefore, the use of an engaging game is effective in promoting awareness of product LCT.

The textile industry is a major contributor to environmental pollution and the youth of today contributes to textile wastage in Singapore through uninformed and poorly thought out fashion decisions. Since game-based learning is highly effective in instilling knowledge, our objective is to develop an interactive and educational game highlighting the different areas of textile waste and to promote conscious clothing consumerism, where youths learn to make environmentally-friendly decisions throughout the purchasing process. We designed a 30-45 minutes board game of choices and deception, TexStyle, for 3-5 players, who completed pre-, game and post-survey. From the post survey, 91.9% of respondents found the game effective in giving them a better understanding of conscious clothing consumerism and 65.9% were willing to practice it. Hence, the educational board game not only instils information about textile wastage, but also persuaded players to consider upcycling, hence proving the effectiveness of our strategy.

Singapore consumes immense amount of energy and every individual is responsible. Targeting tertiary students, this project aspires to reduce their energy consumption through education and raising awareness. We designed a board game to educate students, as games are more captivating as a teaching medium, and compared the retention in knowledge of the 32 players with 32 students who only read a descriptive essay. Pre- and post-surveys tested knowledge gained from the two teaching mediums and the data was analysed using a paired T-test. We found that 80% of students sampled expressed more inclination to modify their behaviours to reduce consumption. More students who played the board expressed that they were likely to change their habits than those who read the essays. Engaging students with games thus prove effective in educating and raising awareness of tertiary student, which could in turn motivate them to reduce energy consumption.

Food wastage, one of the biggest contributors of greenhouse gases, is increasingly pervasive in Singapore. RVRC’s dining hall discards on average, 9.28kg of unserved cooked rice from trays daily. We aim to alleviate rice wastage by upcycling the unserved rice, using minimal additional resources, into a desirable consumable product for RVRC students. To promote the cause, we simplified the production process to attract other students to undertake upcycling themselves. We formulated an easy-to-follow recipe to produce tasty crackers and conducted surveys i) on students to assess desirability and ii) on House-committee members to gauge their response to the production process. Our crackers were well-received by RVRC residents and House-committees showed interest in personally carrying out the production process, finding it easy-to-follow and meaningful in reducing rice wastage. Therefore, our recipe which produces a desirable product, is easy to implement and can effectively tackle rice wastage in the long run.

Reducing high domestic water consumption has been an important priority of Singapore’s water conservation efforts (Tortajada and Joshi, 2013). In a typical Singaporean household, showering, flushing, kitchen and laundry contributes to a significant proportion of water use (Tan, 2016). In particular, laundry contributes to 19% of domestic water consumption, and a significant proportion of it is due to water wastage from underloading the washing machine as more water is being used than needed (Kruschwitz, Karle & Schimtz, 2014). Our survey findings revealed that a significant number of RVRC residents wash laundry on a reduced load, resulting in significant water wastage. Thus, to address this problem, our group will develop a manual washing machine prototype, the Washing Cycle, that serves as an alternative to wash small laundry loads with less water. Our prototype adopts a top load design to avoid water leakage and is powered manually and thus does not use any electricity. We evaluated our prototype using 3 criteria: water efficiency, spin efficiency and stain removal (Alonso et al., 2017; Merediz, 2009). Focus groups were also conducted to assess the user’s experience for our prototype during our trial run. Finally, the results obtained were analysed to provide future recommendations for further expansion of the project.

Over the past ten years, the food waste recycling rate has been stagnated between 10%- 16%, with significant portions of food waste still being incinerated (NEA, 2018). Composting can be used as an effective method to recycle daily food waste from Singaporean households (Khoo et al., 2010). Upon conducting a preliminary survey, our team has discovered that most households dump their food waste indiscriminately, with many respondents citing smell and lack of composting knowledge as their primary reasons for not composting. The experiment aims to provide an effective and efficient method of composting tailored towards alleviating concerns regarding performing composting indoors. Our group will explore two types of composting methods, black soldier fly larvae, and blue Malaysian worms. Using specific amounts and types of food waste, we will reach a conclusion regarding which method is best suited to the household environment. We promoted these methods to households through the distribution of instructional materials to increase the composting knowledge of our target population. Finally, a post-experiment survey was conducted to measure changes in individuals’ perceptions and receptiveness towards adopting composting practices at home, which was used to gauge the effectiveness of our project.

RVRC as an environmentally friendly college has many greeneries in the college. To maintain the lawn and the plants, gardeners need to use a manual watering system, watering them manually on a regular basis using a water pipe. According to Kodukula, Prasad & Charles (2005), the manual watering method may cause inefficient water usage. Water is a scarce natural resource, especially in Singapore. Our project aims to introduce a way to reduce water usage with a more efficient method, specifically on the RVRC lawn. After analysing the disadvantages of the existing method, we had created a new smart irrigation system, which can measure the moisture level in the soil and turns on the light indicator when the soil hits a certain humidity level. The amount of water used by the smart irrigation system is compared with the amount of water used by the manual watering system. The data collected from our observation has shown a significant decrease in the amount of water usage when the smart irrigation system is compared to our initial quantitative measurements of the manual irrigation system. However, this observation is limited to the RVRC lawn and is only representative for those particular biogeographical conditions. Hence, further improvements in the future in covering larger scope of area is highly suggested.

Academic Advisor: Dr. Florence Ng

The phenomenon termed “Fast Fashion” refers to the rapid rate at which clothing are produced by fashion companies, resulting in transient clothing trends that change every few months or even weeks. This encourages irresponsible clothing consumption habits which therefore results in severe environmental consequences. Our project investigated the extent of irresponsible clothing consumption habits amongst NUS students and their degree of awareness of sustainable clothing consumption practices. We conducted a survey on NUS students to investigate the degree of awareness on the topic of responsible clothing consumption habits and used the data collected to develop a mobile application that aims to bridge this knowledge gap. Our survey results have shown that NUS students not only practice irresponsible clothing consumption habits such as the impulsive buying and resultant disposal of excess clothing but has low awareness of how to change these unsustainable habits. This is shown quantitatively by the data collected. The mobile application developed therefore serves to take advantage of the tech-savvy and technology reliant nature of NUS students to increase the awareness and convenience of practicing sustainable clothing consumption habits. A focus group was then conducted to test the feasibility of the application by gathering feedback on how to improve user satisfaction and to better understand what would incentivize users to download and use the application. Feedback gathered was used to improve the functionality and appeal of the application.

Academic Advisor: Dr. Florence Ng

The improper disposal of huge amounts of plastic waste has caused serious environmental issues around the world. Disposable plastic cutlery, one of the sources of plastic waste, has significant negative impacts on marine wildlife, because disposed plastic cutlery in the ocean is frequently ingested by marine animals, which can cause their death (Wilcox et al., 2016). Disposable cutlery is widely used because of its convenience and low cost, and consumers usually do not have another option apart from plastic cutlery when taking away food. Our project thus aims to promote edible cutlery as an alternative to plastic cutlery within Ridge View Residential College (RVRC) and test students’ receptivity to it. To achieve this, we came up with our own recipe for edible cutlery, and there were a total of three rounds of testing. In the first two tests, we examined the edible cutlery we made in terms of usability, taste, and quality, and we also invited our friends to try our cutlery. Based on the feedback we collected, we made our third batch with two flavours, Italian herbs and vanilla. We then brought the cutlery to students in the dining hall and conducted a post-survey to collect their feedback. The results of our post-survey shows that students were generally receptive towards our edible cutlery and more than half of them were willing to continue to use it. They also gave valuable suggestions on how to improve them. Looking forward, we could implement our project throughout NUS.

Academic Advisor: Dr. Florence Ng

In Singapore, the use of air-conditioning is responsible for 24% of its electricity consumption (Abdullah, 2017). As the nation’s energy usage grows, its carbon footprints grow larger and become more harmful than before. This results in disastrous impacts on our environment, including rising temperatures and sea levels (MEWR, 2019). The issue becomes even more problematic upon the realisation that electricity wastage is still an ongoing problem today. While efforts to encourage conservation through social nudges have been present, they have generally been unsuccessful as there is still a high amount of electricity wastage, given the unpredictability of human behaviour (Houde, Todd, Sudarshan, Flora & Armel, 2013). Hence, this project aims to explore the effectiveness of alternative methods to conserve electricity, namely automated technology. Relating the observed issue to Ridge View Residential College, our initial survey found that an astounding 66.7% of respondents witnessed the air-conditioner left running while unused in the lounges three or more times per week (n=52). With this number in mind, we implemented our solution that automatically switches off the air-conditioner by connecting it to bidirectional infrared sensors that detect human presence and absence in the lounge. After comparing the amount of time by which the air-conditioner was observed to be left on unused before and after our solution was implemented, we concluded that electricity wastage has been reduced, with the sensors in place. Hence, we put forth the recommendation to shift future conservation efforts to technological-based methods in order to effect real, effective change.

AY1819G53- “Reusing Greywater”

Chng Kai Yi Kimberly, Choo Run Kang Neville, Foo Chuan Yew, Jin Jin, Nicholas Lowie

Academic Advisor: Dr. Florence Ng

The need to conserve water rises as pressure on water supplies increase due to rising demand from population and economic growth (Grafton, et al., 2013). In particular, Singapore’s water demand of 430 million gallons per day, is expected to double by 2060. Hence, there is a need to manage water consumption to ensure supply meets demand (PUB, 2019). There have been many nationwide campaigns in place to reduce water consumption. Among them, are initiatives promoting the reuse of greywater from washing machines for non-potable purposes such as toilet flushing. Lack of widespread adoption however, may be due to perceptions of health effects or belief that using recycled water represents a decreased standard of living (Bakare, et al., 2015). Our project explores the possibility of reusing greywater by assessing the quality standard of greywater in RVRC before and after treatment by simple filtration. By collecting greywater from washing machines within RVRC and the use of a simple filter with activated carbon to remove undesirable physical and chemical substances, we aim to compare the contents of the filtered greywater with raw, untreated greywater using a complete water analysis test kit to evaluate its viability for reuse. This will be analysed through the greywater quality guidelines set by PUB and parameters such as pH and total residual chlorine. The effect of treated greywater on plant growth will then be quantified to certify that it is clean enough for non-potable reuse like irrigation. Our projected findings would be that plants will be able to successfully grow when watered with the treated greywater. Through greywater recycling, less water would be wasted, reducing total water consumption within the college.

Singapore is currently facing 100% light pollution (Robert, 2016). Excessive artificial light at night leads to light pollution which endangers biodiversity by distorting animals’ night habits like reproduction and migration (Hölker, Wolter, Perkin, & Tockner, 2010). Previous research done by G.Eisenbeis and Hanel (2009) covered how the type of light source and the spectrum of light would affect the insects’ behaviour towards artificial light sources but there is little research done on the effects of how light orientation will affect the insects’ behaviour.  The objective of our group is to replace RVRC lights to a more insect-friendly light. We will be investigating the objective by experimenting the combination of colour of light and orientation of light source that will have the least impact on insects. The aim of the project is to test the different light colours- white, blue and amber and the different orientation of light source upwards, downwards and downwards (cone shape). The prototype will trap the insects that are attracted to the light bulb and the number of insects trapped will be counted. Lesser number of insects trapped will indicate that the combination is less harmful. From our experiments, we have found that the light orientation of downwards (cone shape) and white colour light has the least number of insects trapped on the sticky tapes. Therefore, we can conclude that the combination of downwards (cone shape) and white light is the least harmful to the insects.

Academic Advisor: Dr. Florence Ng

Given the undesirable and unsustainable future of Singapore’s current energy supply, there is a need for an alternative energy source like wind power to replace our heavy reliance on unsustainable energy sources like Natural Gas (Energy Market Authority. 2018). This project aims to determine the feasibility of installing wind turbines in RVRC to power up a 20000mAh power bank. We are going about this project by building our own version of wind turbine using low cost, recycled materials such as water bottles and umbrellas. Initial testing of our prototype involves putting it in a controlled environment of using a fan to blow at the turbine at a constant speed of 5m/s which is higher than the actual average wind speeds. Since results may vary between the controlled experiment and the actual experiment as there are variables like weather that will affect the wind speeds and its consistency, we decided to test the prototype at RVRC (Ridge View Residential College). We tested out the average wind speeds using an anemometer at 4 different locations, on different timings throughout a week, we identified that the RVRC Tower Block Level 8 balcony as the optimal location for installing and testing our wind turbine. Further testing is needed to account for variations in the yearlong weather patterns and the different monsoon seasons which have different wind directions that can affect the results of our experiment.

Academic Advisor: Mr. N Sivasothi

Excessive plastic usage especially by single-use plastics like plastic bags and plastic cups has led to excessive plastic waste around the world (World Economic Forum, 2016) and Singapore’s contribution is more significant today (Channel News Asia, 2018). With the increased incidence of ‘Bring Your Own’ campaigns, we hope to extend this to single use plastic carriers. We identified staff and student consumers of LiHo drinks in NUS as a target audience for the adoption of a BYO cup holder to replace the free plastic carriers issued by LiHo. We found that 58.3% of students (n=48) are not aware of sustainable alternatives to plastic carriers. But some 75% are willing to use reusable cup holders. With a small number of   reusable cup holders, we examined consumer receptivity to the adoption of this alternative.

Plastic waste is a major global problem. In Singapore, only 6% of 815,200 tonnes of plastic waste  was recycled in 2017 (NEA, 2017). Based on ZeroWasteSG’s (2016) estimate, some 30-70% of total plastic waste were single-use disposables, such as takeaway containers.Our project “Saving Waste with CONTAINSIL” aims to reduce material wastage by NUS consumers with single-use utensils with an alternative design. This will integrate fork/spoon into takeaway containers and be perforated ao as to be easily pushed out of container lids. 88% of 86 respondents indicated that they have takeaway meals between 1 to 5 times a week, and most indicated these were for rice dishes, which the design thus targetted. 90% also indicated they do take plastic utensils, reflecting a high demand.  Most (90%) also expressed interest in our idea. based on our calculations on the monthly use of containers within NUS canteens, this design could lead to a reduction of some 245 kg of plastic waste per month.

Academic Advisor: Mr. N Sivasothi

In Singapore, food waste comprises of the highest portion of solid waste composition (Bai, 2000).  A component of food waste is “ugly food”, or food which is deemed unattractive and thus “not saleable” (de Hooge et al., 2018). For ugly food to be redirected from food waste, it must be accessible to potential consumers. Here, we seek to  persuade online grocers to sell ugly food to improve its accessibility and convenience. We first participated in an SGFoodRescue rescue event, to gain insights into the wasteful disposal of fruits and vegetables in Singapore. With high volume and affordability, we directed efforts at approaching major online grocers such as Redmart and NTUC. This did not elicit a response, while amongst small grocers, only UnPackt responded initially. We concluded that interest in the viability of ugly food consumption first requires a boost, so we compiled a video of undergraduate responses towards ugly food through blind taste tests and interviews. With this video, we will revisit the issue with online grocers, environmental activists and sustainability-centred social media accounts to boost consideration of the issue.

AY1819G47 – “Reducing soya by-product wastage through repurposing of Okara”

Dong Haiping, Tong Jia Heng, Kezia Kew, Liao Meng, Shawn Ho

Academic Advisor: Ms. Wong Kah Wei

Okara is the waste by-product of soybean, derived from the production of soya products such as soymilk and tofu. Okara wastage is a significant issue in Singapore, with almost 10,000 tonnes discarded annually. Therefore, the overall objective of the project is to identify new ways to repurpose okara to reduce its wastage. The initial method was to develop a prototype DIY mushroom growing kit utilising okara. This was done by substituting okara as a component of the growing substrate, taken from a commercial kit developed by Kin Yan Agrotech Pte. Ltd. Various technical issues were encountered in the primary testing stage, and changes made during secondary testing did not effectively solve these issues. Requiring further research, it was concluded that using okara to grow mushrooms might not be an easy, viable option of repurposing okara. The second method was using okara in baked goods. This was done by modifying online recipes of vegan okara chocolate brownies, thereafter holding a focus group session for demonstration and taste test. According to post-session surveys, tasters had generally positive comments about the brownies, and they agreed that the baking process is simple and easy-to-follow. Therefore, it was concluded that using okara for baking is a suitable, viable option of repurposing okara.

Academic Advisor: Ms. Wong Kah Wei

Inculcating proper waste management habits among Singaporeans is of paramount importance as the landfills will be filled by 2035. Despite continuous efforts to integrate environmental education into the formal education system, many are still unaware of proper waste management methods and do not recycle regularly.

Thus, our project aims to engage children aged 4-6 in activities that will raise their awareness on the importance of proper waste management. As young children require auditory and visual engagement to internalise concepts effectively, we utilised books, skits, and games to teach them the importance of recycling. The children also learnt about upcycling through craft activities where they made toys from recyclables.

To examine the effectiveness of the strategies employed, we assessed the change in children’s awareness by noting their behaviour and responses and surveying the parents and interviewing the teachers before and after the activity. Based on our findings, we recommend similar methods to increase the sense of environmental stewardship among children.

Academic Advisor: Ms. Wong Kah Wei

Experiential learning is the process of learning through reflecting on doing. There is an alarming lack of awareness on environmental issues amongst youths in Singapore today, and education is key to curb the issue and spread awareness on the environmentalism movement.

In our project, we aim to enhance the most enjoyable learning activity used in GEQ1917 to increase students’ learning of sustainability. Current activities were solely used to garner interest in the topic. After surveying RVRC students and their experience using learning activities applied in GEQ1917, our findings showed that 48.5% of respondents enjoy games the most. Thereafter we created a transferable lesson plan with elements of gamification and improved upon the gaps in implementation of the preferred learning activity (Go-Fish Game).  We conducted trials on non-RVRC students selected from a mix of faculties. A focused group discussion was held after the lesson to assess their knowledge on the topic. The results showed a considerable improvement in the achievement of learning outcomes. Thus, we recommend incorporating more of such elements in any educational programs which have the purpose of enhancing student’s learning in sustainability.

Chen Bo Han, Ji Yuxuan, Liu Huiyi, Shi Wen, Su Haotian

Academic Advisor: Mr. Lim Cheng Puay

In Singapore, 95 percent of energy is generated from natural gas, a non-renewable resource while only the remaining 5 percent is sourced from renewable sources, such as solar energy. Hydropower is traditionally neglected in Singapore due to the lack of a waterbody as a sustainable resource. However, research on harvesting rainwater to generate electricity through micro or pico generators has provided an alternative approach to hydropower. Singapore’s tropical geographic location provides plenty of rainfall, with 190 days of rain, and mean annual rainfall of 2165.9mm. This is an area for hydropower generation that has the potential to be tapped on.

This project seeks to evaluate the feasibility of generating electricity from tapwater as a supplementary energy source on a smaller scale of Ridge View Residential College (RVRC). Targetting taps used for watering the RVRC garden, we will test the water flow through a pico-hydropower turbine to obtain voltage produced. This data will finally be compared to the voltage required to power common appliances.

Artificial lighting contributes to up to 25% of a household’s electrical consumption while creating excessive light pollution. We aim to half the amount of electricity consumed by LED lights in the rooms in RVRC. We conducted a trial with 20 RVRC students by removing one existing LED tube in their rooms. After a week, we conducted another survey to assess how this change has impacted their productivity and living condition. Most residents did not observe any significant difference in apparent brightness and are content with 1 LED tube. We hope that the results would aid students in making a more informed and positive decision by removing one of their light tubes to save electricity and reduce e-waste.

Consumers are straining landfills with massive amounts of waste and incessantly buying products with significant carbon and water footprints. Motivated by a stagnant recycling rate in Singapore, we have launched a Telegram peer-to-peer trading channel for NUS students and staff. On this platform, members can list items for donation and claim items already listed via simple messages. A survey conducted to gauge the receptivity of students to such a platform yielded promising results as over 80% of respondents showed interest in donating or using second-hand items. A large proportion of respondents also reported disposing of various usable items every semester, signaling the potential of such a platform. While similar trading platforms already exist, our project differentiates itself as it increases the accessibility of such a service by implementing it in a popular messenger application. Since the launch of our Telegram channel, we have facilitated multiple item transfers and amassed over 50 members. All claimants indicated that they were satisfied by the condition of items received and if not for this platform, 75% of them would have gone on to buy a similar new item elsewhere. Reinforcing our promise of convenience, all transfers were made in RVRC and were completed at least 18 hours faster than the fastest transaction on the pre-existing trading platform. We have successfully met our objective of sparking joy through the sharing of used items and fostered an awareness of the potential of item upcycling.

Academic Advisor: Mr. Lim Cheng Puay

Food waste in Singapore has risen by over 40% over the last decade, amounting to over 800,000 tons per year. However, only 16% of this volume of waste is recycled. Thus, there is a need to increase the food waste recycling rate through innovative and inexpensive means. Black Soldier Fly (BSF) waste processing is a growing area of research due to their ability to eat up to 4 times their size, low cost, and space efficiency. The aim of our project is to increase youths’ willingness to adopt Black Soldier Fly food waste recycling in their respective homes. Our group conducted a pre and post survey on youth aged between 15-30 years on Instagram, with an educational campaign between the release of both surveys.  We also created a prototype of a small scale BSF food waste recycling kit and conducted focus groups to test its feasibility as a household recycling system. We received feedback from BSF researchers on our prototype which enabled us to create a more efficient and feasible system. Our survey findings have shown that educating consumers on how the BSF process occurs results in an increase in receptiveness to adopting BSF recycling. More research and information is needed to be shared among the public before we can effectively implement BSF recycling on a larger scale.

Singapore produces an alarming 60,000 tonnes of electronic waste (e-waste) annually, making us the second largest e-waste producer in the Southeast Asia region. The average Singaporean produces 11kg of e-waste annually. Unfortunately, only 6% of the total e-waste produced in Singapore is being properly recycled. According to NEA Survey, 60% of Singaporean consumers said they do not know or are unsure of how to recycle their e-waste. E-waste is normally traded in/re-sold, thrown away passed to delivery men. There are harmful effects of e-waste on both the environment and human health, due to toxic metals found in phones such as lead. With our preliminary survey, we realized that the lack of awareness is a key reason exacerbating the growing problem of e-waste. As such, we set up an e-waste booth in UTown in NUS to raise awareness of this issue. We liaised closely with external organization, namely a recycling company ViroGreen, who provided us with banners and an e-waste recycling bin, and a phone assessor Next Telecom Pte Ltd. At the booth we put up educational posters, banners and the recycling bin for participants to drop off e-waste. The on-site phone assessor provided a price quote to participants who wish to sell their old phones. The life cycles of such phones will be prolonged as these phones are once again circulated and used, showing participants that everyone can play their part in reducing the amount of e-waste generated.  More than 200 people participated at the booth in the two days, and they were made more aware of e-waste.

According to National Environmental Agency, approximately 800 tonnes of food waste was produced in Singapore in 2018 and only 16% was recycled. Food waste is also predicted to continue to increase with the growth of Singapore’s population. However, even with elaborate food waste strategies, the issue of food waste persists and majority of the food waste contributed by households could have been prevented at the beginning. Households are also found to be one of the main contributing factors to increasing food waste. Our project aims to nudge changes to households’ behaviours by raising awareness of cooking with food scraps, and studying households’ receptivity to cooking with food scraps. We created a consolidated web page that consists of self-created videos, text recipes and supplementary videos to showcase ways to cook with food scraps. We then assess viewers’ level of understanding and receptivity to cooking with food scraps through a feedback survey. Our results shown that majority of the respondents found our web page to be useful in raising their awareness of cooking with food scraps. Majority of the respondents are also receptive to cooking and consuming food scraps. In short, the use of video and text recipes on a website appears to be a feasible approach to increase household’s awareness and receptivity of cooking with food scraps, which would alleviate the problem of food waste in Singapore.

Academic Advisor: Dr. Chua Siew Chin

95% of Singapore’s electricity is generated using natural gas. While natural gas gives Singapore a stable and well-connected electrical grid, it is unsustainable due to the high environmental and energy cost in extraction. Solar energy as an alternative to natural gas has been implemented in recent year. However, hydropower research in Singapore is still in its infancy. According to Meteorological Service Singapore, it rains an average of 167 days a year and much of the rain is heavy. Furthermore, Singapore has 8000 km of drains, rivers and canals. These gives Singapore a lot potential in harnessing hydropower from rainfall. Our group aims to examine the feasibility and efficiency of hydropower generation using Singapore’s rainfall, with minimal modifications to existing infrastructure. In particular, our project focuses on generating power from the rainwater harvesting system deployed by newly built HDB flats. We assembled a prototype with a small hydro turbine, water hose and a funnel to examine the effects of various parameters on the efficiency of hydropower generation. From the data collected and studies done on Singapore’s infrastructure, we examined whether hydropower from rainfall collected by buildings would prove to be a viable supplement to Singapore’s energy supply. While its prospects initially seemed promising, much remains to be developed and researched on, for the results from our experiment falls short of our expectation. However, it is still possible that hydropower generation from rain fall could be integrated into buildings and underground drainage systems to generate electricity on a larger level.

Food systems contribute to 19% – 29% of global greenhouse gas emissions caused by humans (Vermeulen, Campbell, & Ingram, 2012). However, food consumption and greenhouse gas emissions are often not associated with each other. From a survey we conducted, there is a general lack of awareness on the carbon footprint of food consumed by consumers in Singapore. Hence, we decided to use carbon labels to encourage consumers to pick food choices with smaller carbon footprints. Similar to a nutrition label, a carbon label highlights the carbon footprint of a food item, which is the measure of the total amount of carbon emissions accumulated over the life stages of a product (Wiedmann & Minx, 2008). We implemented it in the RVRC Dining Hall and compared the amount of consumption between different food items in the week before and after. We also created a survey on the side that imitates the addition of a carbon label to measure the general public’s response to a carbon label. By comparing the before and after findings, we found that the labels were able to cause a slight change in consumption, encouraging the RVRC residents to pick the options with a smaller carbon footprint. Similar results were found in our survey, leading to our conclusion that a carbon footprint label can slightly influence food choices in a positive way. Further implementations in Singapore should investigate utilising carbon labels on a larger scale to obtain more significant results.

Academic Advisor: Dr. Chua Siew Chin

While landscape designers often try to incorporate green spaces in urban landscapes, they are usually done with the intention to green the area for human benefits, and often neglect the habitability of wildlife. Research has shown that sound and light pollution can harm the wildlife ecosystem psychologically, mentally and physically. It is important to consider the anthropogenic effects (light and sound) because of human activities from these urban landscapes to figure out the best conditions for wildlife survivability in nearby vegetation. Our project focused on the NUS campus, and measured the damping effect of vegetation with incremental distances from nearby buildings to vegetation. We researched on the acceptable range of anthropogenic effects that wildlife can tolerate, and juxtaposed it against the data we have collected to find an association between foliage density and its damping ability. With these information, future campus infrastructure designers can better plan their project such that buildings are placed at a comfortable distance from the vegetation with minimal impacts on wildlife. Foliage density was classified into sparse, normal and dense using a Secchi Disc, a method modified from aquatic sampling. Light and sound data were measured with incremental distances of 5 meters up to 25 meters away from buildings using a REED environmental meter and datalogger. Our results concluded an overall decrease in light and sound data with incremental distance. A more comprehensive research can be incorporated with our project findings for landscape designers to plan their future projects.

In 2010, toilet paper accounted for fifteen per cent of the world’s deforestation (Robbins, 2010) and yet, we observed that many people are still unaware of the extent of deforestation and pollution of water bodies that comes with it. In 2018, an average Singaporean used 7.5kg of toilet paper, and this number is set to increase (Statista, 2018). Our project aims to look at the perception and awareness of RVRC residents on sustainable toilet paper. At the same time, increase their knowledge on the environmental issues and alternatives of toilet paper through campaigns and a trial. Using Ridge View Residential College (RVRC) as our case study, our quantitative survey showed that there is indeed a lack of awareness on the environmental problem surrounding toilet paper. Additionally, respondents also scored low on the awareness of alternative toilet paper that are sustainable and currently available in the market. Our group launched awareness campaigns including a trial and informative and experiential posters across RVRC. Our post-campaign survey indicated an increase in awareness and interest in sustainable toilet paper among the target audience. The results of our project can help suppliers of sustainable toilet paper to refine their marketing campaigns towards university students in Singapore.

In the increasingly high-profile battle against food wastage, a prominent culprit would probably be surprising to many—schools. Data collected by past GEQ groups (GEQ Group 31, 2016; GEQ Group G01-B, 2017) demonstrate that a noticeable percentage of food waste come from school meal plans, with an estimated 15% of the meals prepared in Ridge View Residential College (RVRC) being thrown away because they are unserved. As such, our group aims to design a solution to better match meal demand and supply in RVRC through the development of a digital platform that allows residents to pre-indicate their meal choices. Our methodology comprises an online survey evaluating user receptivity towards our mobile application, as well as a beta testing period in weeks 10 – 11. After which, we will analyse the findings from our beta test in order to evaluate the feasibility of our prototype. Preliminary results indicate that an overwhelming majority of RVRC residents were open to the concept of a new and more efficient mobile app system where they could pre-indicate their meals up to 7 days in advance. This entails that there is an existing market of users who would be willing to participate in our trial tests and thus drive adoption in the future. However, due to the time-intensive nature of our mobile application development, we will only be able to do our evaluation in week 11 and therefore will only be able to draw conclusions later in the semester.

Paper wastage is a perennial issue in Singapore. 1,144,800 tonnes of paper and cardboard waste were generated in 2017, of which only 50% was recycled (National Environmental Agency [NEA], 2018). Despite Singapore’s efforts, the paper recycling rate has remained around 50% since 2005 (NEA, 2016), indicating a chronic problem with paper recycling. As the flagship university in Southeast Asia and a major consumer of paper, the National University of Singapore (NUS) offers a promising testbed for sustainability solutions addressing the paper wastage problem. Our project explores the circular economy approach in ameliorating paper wastage among students in NUS. Based on our analysis of the data gathered by AY16/17 G03-A, we conclude that there is potential demand for an online peer-to-peer marketplace where students can monetise their used notes and contribute to environmental sustainability at the same time. Capitalising on the popularity of the smartphone application Telegram, a chatbot was developed to serve as a decentralised peer-to-peer marketplace for students to buy and sell academic resources. In addition, a pilot test and an end-user survey were conducted to gauge students’ reception of our project. Through drawing upon the data we obtained, we understood that we must be cognizant of consumer preferences, product differentiation, and the idea that addressing the awareness-behaviour gap is crucial in promoting tangible improvements for campus sustainability. We hope that our project would be useful for further exploration in the implementation of efforts towards achieving campus sustainability.

Academic Advisor: Prof. Adekunle Adeyeye

Reducing food waste in higher education institutes is worth investigating because food wasted in such institutions is significant. We aim to launch our measures in RVRC and eventually expand to other residential colleges in NUS if they are successful. Our goal is to tackle food wastage through both a digital platform and physical measures, by reducing both the amount of food that is cooked but not taken by diners, and the leftovers generated by diners at the end of meal services. We obtained data from caterer Chartwells on the amount of food waste before and after our trial, and conducted a survey on food waste patterns in RVRC to determine the main causes of food wastage. In the survey, nearly half the respondents mentioned that they fail to finish the food on their plate “sometimes” or more frequently. Of those, over half cited portion sizes being too large as a main reason for their plate waste, while over 75% indicated that quality of food was also a factor. Based on these results, we implemented strategies to tackle both significant causes of wastage. We developed a Telegram chatbot to provide an improved channel for diners to provide feedback on their meals. We also introduced a self-serve rice station for diners to adjust their rice portions based on their needs, and allowed free takeaway of meals during the end of a meal service to reduce leftovers. Our trial produced promising results for self-serve rice stations as an immediate means of reducing food waste, and for the Telegram chatbot as a way to improve the quality of dining hall food, thereby reducing wastage caused by diner dissatisfaction.

Plastic straws affect more than 700 marine species and are estimated to be found in 90% of seabirds and sea turtles. The 2015 video of the sea turtle with a plastic straw stuck up its nose sobered many into the fact that plastics in our seas are taking a toll on our marine species. Closer to Singapore, the introduction of straw bans has been widely regarded as a step towards a world consuming lesser plastic. However, there are still cases such as the iReject campaign in NUS that was highly criticized upon its launch. This was surprising given that university students are supposed to be aware of the environmental impacts of plastic straws. From our survey targeted at NUS students and staffs, we found out that 69.7% of respondents are aware of the harms of plastic straws and yet continue to use them. Users still largely prefer the use of straws, and thus, our project seeks to create an environmentally friendly alternative: edible biscuit straws, which will be able to fulfill practical needs of consumers and their strong reliance while reducing its impacts on the environment as opposed to plastic straws. Our group created prototypes with the aim of achieving close functionality to plastic straws. Through various baking sessions, we tested the usability of different materials and how long they can last in liquids to better cater to the needs of the consumers. We managed to derive a recipe that makes straws of relatively good functionality. Results of workshops conducted also showed that the NUS community is generally receptive of and eager to try out edible straws.

Academic Advisor: Prof. Adekunle Adeyeye

Packet drinks are often favored due to their long shelf life and ease of storage, but come with attached plastic straws which are separate from the carton. These straws are often accidentally discarded and form a substantial part of marine pollution. Given the environmental threat that plastic straws are known to pose, our project aims to find an engineering solution to this problem by integrating straws into the structure of packet drinks, thus eliminating the need for external straws. To achieve this, we examined current packet drink designs before forming a preliminary prototype for our solution. After finalizing the design through an engineering design approach using various materials, we formed an improved version of the prototype using materials from a deconstructed packet drink to verify that it was feasible when using the actual components of current packets. A survey was then conducted on the general public. The quantitative data we subsequently obtained indicated a few key findings; first, that 74% of respondents used packet drinks more than once a year, second, that over 70% of respondents deemed straws to be necessary when consuming packet drinks and third, that 89% of respondents preferred our design over the existing one if both were available for purchase. Qualitative data was also collected to understand what consumers deemed to be limitations and areas of improvement for our design. Having improved on our solution based on this data, we now intend to approach manufacturers for feedback regarding the feasibility of implementing our design.

Fong Hok Shing Anson, Jelicia Lim Xin Yu, Spencer Kwan Junhui, Vaarsha Nair

Academic Advisor: Ms. Sadaf Ansari

With the rapid increase in Singapore’s urban density, greenery on walls and roofs is incentivized by the Building Construction Authority for the following reasons – it provides aesthetic relief, creates usable green spaces, and reduces Urban Heat Island effect by cooling ambient temperature (URA, 2017). New projects on the NUS campus incorporate such greenery to promote a sustainable campus. Our project assessed and raised awareness about the use of integrated greenery by NUS students who live on campus, with a focus on University Town residences. Our research identified three factors that impact greenery use by students; 1) awareness of location, 2) perception of these spaces, and 3) design preferences for these spaces.

The project adopted a three step strategy for primary data collection. The first was conducting field trips to measure current use – including observation and user interviews. Preliminary results indicated that green spaces, with the exception of Utown Green, primarily function as transit zones. The second step was to interview staff from the Office of Facilities Management (OFM) to understand operational costs and challenges of maintaining green areas. Our final step was to conduct a workshop with the target users in UTown.

The results from our workshop indicate that students are not aware about the location of these spaces, and that they would be willing to use the spaces if improvements were made such as the installation of lights or better landscaping. Our project concludes with specific recommendations to OFM to enhance greenery use in Utown.

Academic Advisor: Ms. Sadaf Ansari

With a rapid increase in population and consumerism, an unprecedented volume of plastic waste is entering our landfills and oceans. According to the World Wildlife Foundation (WWF, 2018), Singapore discards 700 million kilograms of plastic each year and less than 10% of it is recycled. Given a forecasted global production volume of 583.3 billion plastic bottles in 2021 (Statista, 2017), besides having an efficient recycling process, Singaporeans need to have a prudent mindset in using plastic.

Consumer habits need to change from the ground up and our project aims to shift opinion on the use of single-use PET bottles by engaging the student community in a work-with-plastics workshop. In preparation, we explored several different methods of constructing furniture out of used plastic bottles such as heating and fusing the bottles together with a hot gun, glue gun, heated grill etc. However, safety concerns like burns and toxic fumes ruled out heat based options. We finally chose a simple adhesive medium for ease of participants.

During the workshop, we educated participants on the 7 grades of recyclable plastic while making stools out of PET bottles. We measured the effectiveness of our workshop by conducting pre and post workshop surveys. Our results indicated that direct engagement in re-purposing used plastic bottles had a significant and meaningful impact on participants’ perception of the problem of plastic waste, and their individual contribtion to the global problem. We will explore a collaboration with OES to conduct such workshops for the NUS community.

Academic Advisor: Ms. Sadaf Ansari

Fifty percent of bacterial infections in Singaporean patients have become resistant to frontline antibacterial therapies. This is explained by the Antimicrobial Resistance (AMR) phenomenon or the evolution of ‘superbugs’. One of the main reasons for this is patients’ failure to complete the prescribed antibiotics. We found that this is due to a multitude of reasons, but we seek to focus on the one we find most urgent and prospective: forgetfulness. To ensure the sustainability of existing antibiotic treatments, we designed and fabricated a modified and personalized pill dispenser called “SmartPill” containing features to minimize incompletion of antibiotics due to forgetfulness.

We focused on a primary target audience of the Singaporean elderly (>65 years of age) as they account for the greatest proportion of antibiotic consumers of all age groups in Singapore. The key features of SmartPill include portability, visual aids, color, and reminders. The SmartPill’s universal 3D-printed design also allows it to be a phone case built for all phone sizes as it is aimed to be on-person throughout a prescribed course of antibiotics. Its features also help it stand out and serve as an active reminder to reduce incomplete antibiotic consumption due to forgetfulness. We conducted qualitative surveys with pharmacists and doctors at NUH and workshops to test our hypothesis that forgetfulness was the main cause of antibiotic misuse. Our pilot examined the elderly’s use and perception of the SmartPill dispenser over a few weeks of use. Our results found our target group to be strongly receptive to the use of our prototype.

Academic Advisor: Ms. Sadaf Ansari

The trend in using liquid soaps over bar soaps (Willingham, 2016) is harming the Earth increasingly as experts cite facts on how damaging liquid soap is through greater carbon footprint incurred and larger amount of waste generated (HKFP, 2016 & Drahl, 2018). Being a strategic platform for building a sustainable campus, NUS offers great opportunities for students to share their constructive inputs to our project. Our project explored the perception of NUS Residential College students and their awareness of the environmental costs of liquid soaps. We also tested if students could be encouraged to use bar soaps through the design and installation of a soap dispenser prototype, to ultimately encourage the switch to bar soaps use.

We chose RVRC as our test-bed. Qualitative surveys were carried out before and after the installation of our prototype to measure the change in attitudes of residents in using bar soaps. The results indicate that the majority of residents are aware of the adverse environmental impacts of using liquid soaps. The residents also highlighted convenience and hygiene as their main concerns for their continued preference of using liquid soap. Our data also indicated that most respondents were willing to switch to bar soaps if the prototype could address their concerns. We have recommend a more extensive pilot testing of the bar soap dispenser in RVRC, with OHS collaboration, to measure the impact of our idea in nudging residents to using bar soap as a sustainable alternative to liquid soap.

AY1819G25 – “Water Sustainability Education using Collaborative Learning”

Benedict Tjoeng Ruiyan, Lam Sophie, Lim Hao Xiang Sean, Low Zhen Hao Jefferson, Samuel Choy Meng Soon

Academic Advisor: Ms. Sadaf Ansari

Water demand in Singapore has been projected to increase, up to double of the current amount of 430 million gallons a day by 2060 (PUB). With the domestic sector being responsible for 45% of current water consumption (PUB), a reduction in household consumption is paramount to maintain our water supply. Existing literature suggests children form habits more easily and are more impressionable at the young age of 6  (Eccles, J.S., 1999). Our group aims to challenge the effectiveness of the “individual” paradigm by focusing on collaborative learning among preschoolers. Collaborative learning has led to increased efficiency in learning and higher achievement among students (Laal, 2012). We hypothesise that collaborative learning is a better pedagogical approach compared to individual learning. This would be done by measuring the degree of knowledge-retention and behavioural improvements of water conservation habits in preschoolers for both teaching methods.

To test this hypothesis, we conducted an experiment in the form of a workshop. The workshop was split into a test group and control group, focusing on collaborative learning and individual learning respectively. Pre-workshop and post-workshop data was gathered to measure the effectiveness of collaborative learning and individual learning. Results indicate a general receptivity of the target group to the activities of collaborative learning. Our data also indicated that this increased engagement was associated with better knowledge retention and development of water conservation habits. Our recommendation is for more extensive testing of this model to ascertain if collaborative learning can be implemented on a national scale for water education.

Academic Advisor: Ms. Sadaf Ansari

Globally, one-third of food produced for human consumption is wasted (Gustafsson, Cederberg, Sonesson and Emanuelsson, 2013). In Singapore, food waste is also a rising concern with an alarming 40% increase over the past decade (NEA, 2018). Strategies employed for the producer side of food waste have yielded positive results in tackling this issue (Oliver Wyman, 2014). In contrast, efforts expended on the consumer side to reduce their plate waste were mostly rudimentary and devoid of systematic evaluation (Barilla Center for Food and Nutrition, 2012). The purpose of our study was to augment the current strategies of plate waste reduction with choice architecture principles in the Ridge View Residential College (RVRC) dining hall.

Our preliminary field research and survey of Yale-NUS current plate waste monitoring system showed that individuals are more compelled to reduce their waste when comparative figures are presented. Therefore, we implemented a waste monitoring system in RVRC for three weeks that utilised norm-based messaging and community approach to nudge individuals to reduce plate waste. The system displayed an individual’s plate waste amount against two other comparative figures: a constantly updated average plate waste amount and the target plate waste amount for the community. Collected data showed that our system effectively

raised the consciousness of plate waste in the RVRC community because of significantly reduced overall plate waste. Based on the results obtained in our study, we recommend incorporating a comparative plate waste display across NUS campus dining halls to reduce food waste by students.

Academic Advisor: Ms. Sadaf Ansari

Bottled water is associated with many environmental issues: carbon footprint over its life-cycle, non-biodegradable at end-of-life, and pollution generated during disposal by incineration. Singapore has easy access to high-quality drinking water, and the problem must be addressed by a reduction in the consumption of bottled water. We surveyed NUS students to measure their bottled water consumption and understand their perception of water coolers and tap water on campus. The results identified mistrust in water quality from coolers/tap water and insufficient signage about cooler locations on campus as key issues.

Our group adopted a three-pronged approach. We addressed the issue of student awareness with informational posters as studies indicate that posters are an effective method for conveying knowledge and gaining audience attention (Rowe & Ilic, 2009). This was followed by an art exhibition at the RVRC Dining Hall, using single-use water bottles collected from RVRC bins to measure and creatively raise awareness of plastic bottle consumption rates within the residential college. Our final step was the design and launch of a prototype web application of water cooler locations within NUS campus, launched in conjunction with PUB World Water Day. It incorporates navigational features to direct students to cooler locations on campus. Our data indicates that students are willing to change their habits once the awareness gap about water quality is addressed. Student use of our mobile application was also very favourable and we are in contact with NUS Maps for an integration of this app for campus-wide use.

Academic Advisor: Ms. Sadaf Ansari

2 billion people worldwide live in rural areas without ready access to hot water, with over 67% of them relying on burning biofuels such as crop residues or manure for their energy needs. While crop straws are a renewable source of energy, burning them inadvertently produces more than 550 kg of CO2 annually, significantly contributing to global warming (Niu et al., 2017). Our project aims to bridge this energy gap by designing an off-grid solution for environmentally-friendly water heating especially targeted at users in tropical.

The key design features of the water heater we designed are ease of fabrication, portability, and economical. Our prototype circulates water from a storage tank through a network of copper pipes, which are heated when placed under direct sun exposure, before storing the heated water back into the tank. To test this, we built and tested our prototype over 4 weeks to measure water temperature change in a controlled setup. We followed this with a volunteer group experiment to measure user comfort levels of the temperature of the heated water using our prototype and compared it to results from the electric heater.

We found that our solar-powered water heater prototype was able to consistently heat water above the average comfortable hot water shower temperature of 42.8°C. Based on these results, we have shared our prototype with NUS OCIP and recommend field testing the heater during NUS student OCIP visits.

The plastic pollution problem is an issue that affects marine biodiversity around the world. It also has devastating impacts on land ecosystems and makes its way into the food that we consume. One of the ways to increase youth’s environmental awareness is by educating them on the severity of this problem and methods to reduce plastic waste. This research project aims to measure the efficiency of environmental education workshops for students, and test their ability to retain taught information when it is shared in an interactive workshop format.

We tailored an environmental education workshop regarding single-use plastic packaging, targeted at the Primary 3 students in Singapore. Pre- and post-workshop surveys were used to determine student attitudes and learning. The data collected from the surveys was be analysed using SPSS Anova t-tests at a significance level of 0.05. Based on our findings, we recommend that more extensive testing should be done to corroborate our results and determine if such workshops and teaching methods can be adopted by MOE for enhancing student knowledge about sustainability issues in Singapore and to positively influence student behaviour to be more sustainable.

The textile industry is one of the top three contributors to carbon emissions in the world, with Fast Fashion being one of the major factors. The trend for sustainable fashion solutions such as rental fashion has slowly been on the rise (Hooker, 2018). However, a previous GEQ project identified that the root cause for the failure of such sharing models was ‘the disparity between awareness and actions’ attributed to a lack of financial incentive (GEQ G11, 2016). Our project aims to measure the level of awareness among university students about the impact of fast fashion and investigate their receptivity towards rental fashion as a potential solution, when coupled with an inbuilt financial incentive.

We conducted a survey among NUS students (excluding RVRC), to assess their awareness of the environmental impact of fashion, and found that most respondants significantly underestimate the environmental impacts of fast fashion. We then volunteered at the EcoBank Bazaar national event to conduct a focus group analysis and identified key factors that impact receptivity towards sustainable fashion solutions such as clothes swapping and rental. Lastly, we interviewed leading sustainable fashion companies in Singapore such as The Fashion Pulpit and ClosetShare, who shared insights on the business challenges in the nascent rental fashion industry. Using the key indicators of our research, we piloted a formal clothes rental solution at RVRC. Our pilot test findings are concurrent with our research – that in addition to sustainability awareness, financial incentive is a key determinant of success for such fashion solutions.

Effective and sustainable last mile solutions in a transport systems can lead to reductions in carbon emissions by encouraging private car users to adopt public transport. In NUS, the shuttle bus system is a last mile solution which was supplemented by an e-scooter trial called GrabWheels. Our project examined the viability of GrabWheels as a safe, sustainable complement to the campus shuttle bus. We compared unit CO2 emission, efficiency and capacity of shuttle buses and E-scooters and made observations of the threat E-scooters posed to pedestrians, along two popular routes in campus. While E-scooters produce significantly less carbon dioxide than shuttle buses, they are only more efficient during non-peak hours. Parking space was inadequate at some stations, leading to pathway blockages. Most significantly, most pedestrian pathways are not wide enough to accommodate E-scooters alongside pedestrians. We conclude that while E-scooter have the potential to be an effective and sustainable complement, the problems posed in safety and parking areas need to be addressed.

Academic Advisor: Mr. Lim Cheng Puay

The issue of food waste is detrimental to the environment and “if food waste were a country, it would be the third largest producer of greenhouse gases in the world” (Royte, 2016). Furthermore, an estimated 40% of the food losses occur at the final consumer level consumed (Gustavsson, Cederberg, Sonesson, Otterdijk, & Meybeck, 2011). This issue can thus be mitigated through the collective effort of individual consumers. As consumers do not realize the level of food waste generated (De Coverly, McDonagh, O’Malley, & Patterson, 2008), it is therefore imperative to raise awareness on this issue and inculcate a culture of recycling food waste. Our project explored households’ awareness of food wastage and their methods of managing food waste through our survey on consumers (of various ages). 85% of the respondents discard their fruit peels instead of recycling them. In response to this, we conducted workshops to teach consumers how to produce a food enzyme solution. We reached out to RVRC residents and the members of the public and educated them on the uses of food enzymes and the method of developing a food enzyme solution. Results from the workshops showed that than 97% of our participants (n=76) were willing to recycle their fruit peels. The participants also became more cognizant of the existing food wastage issues. Moreover, respondents were willing to share what they learned from our workshops with their family and friends. Thus, this suggests the success of our outreach as participants are spreading the idea of garbage enzyme through word of mouth. In conclusion, we have successfully met our project objective of encouraging households to use garbage enzyme as a substitute for commercial cleaning agents, thereby demonstrating the possibility of up-scaling garbage enzyme making and thereby further spreading this idea to more people.

Academic Advisor: Mr. Lim Cheng Puay

We live in a society based on linear metabolism that has led us to deplete our resources at an unsustainable rate. Singapore has designated the year 2019 towards becoming a zero-waste country and a circular metabolism system can aid in this. Even in RVRC, a residential college based on sustainable living concepts, residents are still attuned to living in abundance with a throw-away mentality. Hence, this project aims to investigate the feasibility of producing fruit detergents created from fruit waste in RVRC, to implement the circular metabolism system.

The project followed a two-way data collection involving surveys and physical data collection. These allowed for the analysis of the amount of fruit waste generated in RVRC, and how feasible it is to substitute commercial detergents with fruit detergents. 50 participants partook in pre- and post- fruit enzyme exposure surveys to understand user engagement with the enzyme. A week-long study of the fruit wastage in the college dining hall was also conducted to estimate the quantity of fruit waste required to produce sufficient detergent for the RC.

The amount of waste collected from the dining hall per week is about 7.8 kg. By collecting the fruit waste for a month, we are able to make sufficient fruit detergent that sustains 600 residents for one semester. As such, the results have shown that there is potential in making a sustainable system that produces fruit detergent from the fruit waste in RVRC to substitute currently used detergents for all the residents.

Academic Advisor: Mr. Lim Cheng Puay

The United Nations announces that the world is fast heading towards catastrophe on account of water scarcity due to insufficient water to satisfy growing water demands (United Nations, n.d.). In 2017, Singapore’s Public Utilities Board (PUB) reported that Singapore is expected to face tremendous water stress by 2040, with the current daily domestic consumption of 143 litres per capita. With the availability of potable water at a twist of a tap, it is no surprise that Singaporeans would hardly give any thought to conserve water. (Straits Times, 2016) Showering accounts for the biggest water guzzler in the household, accounting for 29% (MEWR, 2017), yet it is not notable that a minute less in the shower can save nine litres of water. (PUB, 2017). As such, the goal of the project is to reduce shower water consumption in Ridge View Residential College (RVRC) by incorporating audio cues placed in shower cubicle. It is hypothesized that audio cue is capable of inducing behavioural changes during showering which is similar to how background music affects shoppers’ behaviour. Water consumption is measured by means of a water meter and data will be collected over three weeks; a week with water meters only, a week with audio cues and water meter, and the third week without audio to investigate whether audio has indeed altered users’ behaviour at the shower.

Durians are huge delicacies in South East Asia, with Thailand and Malaysia being the biggest exporters of the fruit. Durians are also starting to gain attention in other Asia countries such as China. Due to this rising prominence, the demand is booming. Thailand, the world’s leading exporter of fresh durian, exports 402,661 metric tons of durian in 2016 alone. (UNCTS, 2016). This directly generates tremendous amounts of waste as on average, 70% of the durian fruit is inedible and thrown away (Cheok, 2016). When durian waste is incinerated or left to decompose, large amounts of methane gas is produced, directly contributing to global warming. Our project explores ways to mitigate such ongoing environmental damage, focusing on finding alternative uses for durian husks to end the life cycle loop of the fruit. We analysed the current life cycle assessments of durians and studied the chemical properties of the fruit, with the possibility of upcycling these contents to substitute disposable packaging in mind. Using NUS campus as a platform for our case study, we conducted a quantitative survey to examine 1) student’s perception and awareness towards the current issue of durian wastage and 2) their receptiveness towards biodegradable products made from durian husks. Our results highlighted a significant lack in awareness of the environmental damage caused by the above problem among consumers of durian. The respondents were also supportive of the idea of biodegradable packaging made from upcycling high fibrous fruits to substitute current plastic ones. Creating such a substitute will directly reduce the environmental impacts and simultaneously educate the public of the critical issue of food wastage.

Food waste is a growing concern worldwide, which poses a threat to the world economically, environmentally and socially (Costello, Birisci, McGarvey, 2016). As RVRC is a residential college which aims to build sustainable life, the food waste in the RVRC dining hall needs to be controlled. Our project asked the food flavor and the amount of food which RVRC’s dining hall provides so that we can find the main reasons why they waste food. Then we explored some suitable ways to reduce the wastage. First, we conducted a survey amongst residents to ascertain reasons for food waste and assess the feasibility of various solutions. Our results show that the main reasons for wasting food are the flavor is not suitable and the food amount is too much. More than half of students want to have the flavor of each dish to be presented on the label so that they can make a better choice. Also, nearly 50% of students will not choose the original size of food if the dining hall provides different size of food. We recommend the RVRC dining hall to write the flavor of food on the labels of each dish. Also, the dining hall can provide food as small, original and large size to give more choice for the student. Students can choose the food amount and flavor better and reduce food waste.

The recent coffee capsule wave has created multiple environmental concerns due to the intricate design of these capsules which have been proven to be hard to recycle. Our project seeks to educate and inculcate a more environmentally conscious consumer market by instilling a focus on extending the life of these single-serve products. Initial surveys were conducted to determine Singapore’s consumer preferences, market trends, and perceptions. The results highlighted a lack of industrial recycling programs and consumers’ disregard for the environmental impact such products cause. Based on these results, products were created that takes advantage of the pods material composition, shape, and structure. The final stage solution comprises of a workshop that leverages on direct education to participants and hands-on activities that will cement our ideas. Through this methodology, the proposed project is able to impart concepts of environmental awareness and alternative actions that can be taken by consumers to reduce the amount of waste created. Of the participants involved in the workshop, 96% (n = 24) have indicated a change in perceptions and attitudes towards their coffee pod consumption. This approach has thus been successful in meeting our objective of inciting attitude changes within households.

Academic Advisor: Mr. Lim Cheng Puay

Coastal cleanups are a highly effective way to remove marine debris and they play an important role in protecting our marine ecosystem. Meso-plastics (debris ranging from 5mm – 25mm) are of particular concern as they are readily ingested by marine life, travel and accumulate up the food chain, and eventually end up in humans. Furthermore, it breaks down into microplastic (<5mm ) with time which has more detrimental impacts. Hence, it is important that this group of marine debris is removed effectively. However, the act of removing meso-sized trash is an inconvenient and labour intensive process. It is also often not cleared by contractors nor collected by cleanup volunteers. Thus, our group aims to explore the use of tools for coastal cleanup participants and organizations to increase the effectiveness of removing meso-plastics which would otherwise be a labour intensive process. To test this out, we used a basket to pick meso-plastics during coastal cleanup sessions. Our prototype basket effectively helped us collect 800 pieces of meso-plastics within a fixed area and time frame of 20 minutes as compared to 150 pieces of meso-plastics collected by the traditional hand-picking method under the same conditions. The results show that our prototype works and the utilization of our tools greatly eases the process of removing marine debris. As a result, we hope to make our prototype part of the preparation package for all coastal cleanup organizations in Singapore to make the removal of meso-plastics more effective.

Academic Advisor: Mr. Lim Cheng Puay

The importance for Singapore to address the problem of water scarcity is hard to be overstated with Singapore’s restricted natural water sources and high-level water consumption, especially domestic water consumption during showering. An awareness survey within RVRC residents and experiments on water heaters in RVRC show that 722 liters of water were estimated to go down the drain without being used in RVRC every day. Our project aims to eliminate cold water waste while waiting for the water to get warm before showering. Our solution is to design an affordable and user-friendly water recirculation structure for the instant water heaters. Due to the lack of necessary certifications from PUB, only a prototype is built to test the theory. The result turns out that when the showering water is under 25℃, the water will be pumped back to the water heater to be reheated. When the water is above 45℃, the user can turn on the showering water-tap and hot water will flow out. Users can control the process with two switches. The whole cost for the system is 60 SGD. A post-survey investigating the public attitude towards the design shows that over 78.5% of respondents are willing to adopt this system. Overall, the system can eliminate cold water waiting time, and it is easy to use and affordable compared to existing households water circulating system.

Academic Advisor: Mr. Lim Cheng Puay

We aim to raise awareness of the importance of food security and wastage in Singapore among the younger generation. Food issues are significant, but relatively unknown and deemed less important in Singapore, given that Singaporeans have easy access to food all the time (Koh, 2018). As such, the main target audience was university youths, who have the highest potential to effect important changes in the future. With that in mind, an educational role-playing card game was developed, which would provide players with information on happenings related to food security and wastage that could endanger Singapore’s food source as well as tips on ways to contribute to sustainability in this aspect. After testing the game on 104 participants, 77% of the participants have gained more knowledge on the issues of food security and wastage, 64% indicated a greater interest and concern for this topic, and 78% felt that the game was engaging and fun. The game has successfully met the objective of raising awareness of the importance of food security and wastage in Singapore among the younger generation. In the long run, this game could signal the start of games as a novel way of educating students about food wastage and security.

Academic Advisor: Mr. Lim Cheng Puay

Many human-wildlife interactions in Singapore usually shows public ignorance in proper behavior and action when encountering wildlife. This conflict exemplifies a deeper problem of a lack of proper environmental education: people meet animals with improper behavior because of a lack of awareness of what they are, and how to deal with them.

At Ridge View Residential College (RVRC), which is located near a secondary forest, opportunities for human-wildlife conflict abound, making this problem more pertinent. Hence, our project aims to ​elevate the awareness of RVRC residents on what to do when an animal enters their living space​ and establish a college-wide ​Standard Operating Procedure for this.

Our initial survey findings highlighted that more than 75% of the respondents were not aware of how to safely manage an encounter with an animal visitor in their living area. Over 90% of respondents also indicated that they were interested in learning about the biodiversity in Kent Ridge and the protocols they should observe in these situations. Thus, we recommend providing an Animal Response Toolkit (ART) for RVRC, as the foundation for a new standard operating procedure. We propose holding workshops in conjunction with the ART, to better educate them on this knowledge. The workshops will be held in partnership with Animal Concerns Research and Education Society (ACRES). 2 such workshops had been conducted with promising outcomes.

AY1819G08- “Waste to Soap”

Gan Jia En, Kheng Yau Dong, Wang Heqiao, Tan Desheng

Academic Advisor: Dr. Florence Ng

Cooking Oil is an essential ingredient that is commonly used in food production globally, which in turn leads to a substantial consumption of cooking oil around the world. For instance, in 2016, 25 kg of edible vegetable oil was consumed per capita in China (Research and Markets, 2018). Due to the significant consumption of cooking oil, a substantial amount of used cooking oil (UCO) will be produced. Thus, our project aims to explore the idea of recycling of UCO by using it to produce soaps. Using UCO from RVRC Dining Hall, we have produced cold-process bar soap and liquid soap in a soap workroom of a local company known as Sugar and Spice. Followed by this is an interview with the dining hall cleaners to enquire about the commonly found stains on the dining hall table. We gathered that the common stains are usually drinks and sauces. We then decided to test out the UCO soaps on different type of sauces instead of drinks as sauces are more oily and hence is more difficult to be cleaned. From our evaluation, it was observed that the liquid soap and bar soap were reasonably effective in cleaning the stains. In particular, the cleaning effect of the liquid soap was comparable to a commercial kitchen cleaner which served as the control. We recommend that further research should be done to investigate the feasibility of producing the UCO soaps in a larger scale to augment its benefits towards the environment.

Academic Advisor: Dr. Florence Ng

Receipt wastage in dining halls across NUS is a wastage of resources and is not in line with NUS stated goal of sustainability. Furthermore, the presence of BPA in receipts could pose health risks to students through dermal exposure (Konieczna, Rutkowska, & Rachoń, 2015; Arbor, 2018). Therefore, our project aims to reduce receipt usage. We first explored student awareness of the potential health risks and environmental impacts arising from the use of thermal paper receipts in dining halls. With residential college members as our survey group, we conducted a quantitative survey to investigate the level of student awareness. Our results showed that student awareness of the health and environmental impacts was high. Students were also open to the replacement of the current receipt system with a more environmentally friendly alternative. With these results in mind, our group proposed that the current receipt dispenser be replaced with a token dispenser. These tokens will replace the receipts as meal credits. They will be made of plastic and will be reused across semesters, ensuring their environmental impact is minimal (Cooper, 2012). The token dispenser will be programmed using an Arduino mini computer and will be fabricated using a 3D printer. We then conducted a trial testing the performance of our machine. With the feedback from the trial, we were able to further improve our design, increasing its feasibility. Thus, we recommend that NUS could consider replacing the current receipt system with the coin dispenser.

Academic Advisor: Dr. Chua Siew Chin

The issue of food waste in Singapore is prevalent and increasingly severe. This city-state generated 791,000 tonnes of food waste, equivalent to the weight of over 3,500 MRT trains (National Environment Agency [NEA], 2018). Outreach initiatives have been implemented to not only raise awareness of the environmental and societal impact of food waste but also to educate the public on responsible food consumption. However, currently, these initiatives have mainly targeted children in the primary school level and above but not pre-school children. Existing literature states that children aged 0 to 6 years old have the brain capacity to absorb information quickly. Hence, good habits are best introduced at a young age to ensure maximum time for their formation and retention. Thus, our project aims to educate children in pre-schools regarding the food waste issue and to inculcate responsible food consumption habits. We conducted a 2-hour food waste education workshop, split into two 1-hour sessions, targeted at pre-school children. To measure the effectiveness of the workshop, we conducted two surveys and Food Poster. Our pre-survey after the first workshop indicates that an average of 10 out of 12 students understood the lesson. Our post-survey after the second workshop indicates the same results hence indicating their memory retained the lesson. Our Food poster collected data of the students’ meal behaviour for 2 weeks. The students did not waste food in any of their meals. We also interviewed the teachers, who state that the children are now motivated to not waste food.

Academic Advisor: Dr. Chua Siew Chin

Plastic waste in Singapore has been increasing in recent years, with disposable plastics being one of the main types of plastic waste (NEA 2019).2 One of the sources that accumulates plastic waste is the use of disposable cutlery when consuming delivered food. Despite their possession of reusable cutlery, most consumers lack the consciousness to decline disposable cutlery when ordering food. As such, our group aims to investigate how we may get NUS students to use reusable cutlery instead, adopting a three-pronged approach to do so. We collaborated with Al Amaans, one of the most popular supper stores among NUS students, and requested for them to verify if students on the line require disposable cutlery when receiving orders. The other two approaches include the development of  infographics which comprise social norm messages, and creating an additional step on supper order forms for students who opt to use disposable cutlery. Based on data gathered over the past three weeks, there has been a small but increasing proportion of students who reject disposable cutlery. These results offer an optimistic sign that the use of these prompts, reminders and messages may aid in encouraging such behavioural changes amongst NUS students.

Academic Advisor: Dr. Chua Siew Chin

Children’s toys are a large contributor to the plastic waste problem in Singapore. They are mostly made out of unrecyclable plastic, and consumed at a high rate. This is amplified by the fact that the toy market in Singapore is growing. Our project seeks to abate the environmental impact of toys by encouraging parents to make their own upcycled toys for their infants using household waste instead of purchasing commercial off-the-shelf toys. To achieve this, we created a guidebook and a DIY kit to help parents. We then test the receptiveness of parents to this idea through interviews, which are analysed with qualitative coding. We also measure the interest of infants in the toys that are created from waste materials using non-participant observation. Our results indicate that infants are generally indifferent to the upcycled toys in comparison to commercial toys. Parents also have a positive response to the DIY kit and guidebook, and suggested that they are willing to give upcycling a shot. This evinces that upcycled toys are a suitable substitute for commercial toys, and parents are ready to make their own upcycled toys. From our project, we hope to ultimately motivate parents to upcycle their household waste to toys by demonstrating to them the ease and benefits of doing so.

Academic Advisor: Dr. Chua Siew Chin

Food waste is Singapore’s fifth largest waste category and made up 11% of the 7.3 million tons of waste generated in Singapore in 2012. Pulau Semakau, Singapore’s only landfill, is expected to be completely filled by 2035 and this has created an urgent need to find a value-added use for waste products. Our group is focused on reusing fruit waste – in particular, fruit peels, which are usually discarded while the flesh of the fruit is consumed. By combining various citrus peels that contain pectin with fruits that contain oleic acid, we tried to create a biodegradable superabsorbent polymer (SAP) that, when placed in soil, enables plants to go without watering for several days. Adapting from a previous experiment (Nirghin 2016), lemon, lime, and orange were used as sources of pectin, while durian and avocado were sources of oleic acid. The effectiveness of the SAPs was assessed in three different ways: by measuring plant growth, soil moisture, as well as water absorption capabilities. We found that all our fruit peel SAPs were effective at increasing the water retention of soil. The challenge however was mould growth on the SAPs, which led us to conclude that the SAP method would only work in locations with low humidity such as an air-conditioned room. Our findings could prove useful among the gardening community in Singapore, who can create their own biodegradable SAP that aids in plant growth, while helping to reduce waste in Singapore by reusing fruit peels, which would otherwise be discarded.

Academic Advisor: Dr. Chua Siew Chin

Clothes cleaning consumes both water and energy, which amongst other negative environmental impacts, could lead to global warming and climate change. Yet, our preliminary survey shows that even in tropical Singapore, respondents are unaware of excess energy consumption at higher temperatures, and primarily select hot or warm laundry wash temperatures. As studies have approximated a linear correlation between electricity consumption and wash water temperature, selecting a lower wash temperature would reduce energy consumption. However, there are limited studies on consumer’s laundry habits and their preference for either a low temperature or high-temperature laundry wash program. Given that approximately 0.015kWh of energy, equivalent of 25 minutes of fan usage, can be saved just by switching from a hot laundry wash to a cold one, our project aims to promote energy savings through a two-pronged approach. Firstly, educational posters will be put up around RVRC to educate residents on the best suited wash temperature for their textile type and the benefits of washing at a lower temperature. Secondly, we would experiment with a laundry sharing program as a viable way to cut laundry energy use. The success of our approaches would be based on pre and post surveys and an observational study on the actual proportion of resident who adopt lower temperature for laundry. This project contributes data on the potential energy savings of different laundry wash temperatures, highlights excessive energy usage in the laundry process and encourage consumers to change their laundry habits and use reduced temperatures.

Academic Advisor: Dr. Chua Siew Chin

Microplastic pollution is a problem that threatens not just marine ecosystem, but also human health (Sharma & Chatterjee, 2017). Approximately 0.1 milligrams of microplastic particles are released by each gram of synthetic textile in each washing cycle (Hernandez, Nowack, & Mitrano, 2017). With this in mind, we investigated potential mitigation methods in reducing the concentration of microplastics in laundry discharge. We start by identifying potential factors that contribute to amount of microplastics in laundry discharge, namely type of laundry detergent and the “wear and tear” factor. Our experimental results verified the presence of plastic microfibers released by RVRC launderettes during washing of synthetic textiles. We hypothesised that using liquid detergent will cause less microplastic shedding compared to powder detergents and older clothes will shed more microplastic as time progresses. Hence, we propose using liquid detergents for laundry and wash synthetic clothings with the appropriate washing guideline to improve their longevity.

Industry Advisor: PUB

Water conservation is a critical issue globally but city-dwellers with access to cheap water may need reminders about conservation. Most student residents of RVRC agree this is important and would participate in a fun facts poster campaign or competition. We recorded water consumption over two weeks during a “do you know” poster campaign in Block D and the following week; and also at Block E as control. In Block D, the average daily water consumption was 1,670L during the campaign week and 1,430L the week after. At Block E, average water consumption remained at 2,000L/block over two weeks. Meanwhile, the strongest reaction by residents to the water rationing exercise in RVRC was “meaningful”, followed by “Inconvenient”. A longer period of monitoring would provide more reliable data.

Plastic pollution currently poses a serious threat to our natural environments, flora and fauna. A major contributor to this pollution are food service operations, even on tertiary education campuses. In this project, we investigated the reduction in the use of plastic bags used in RVRC dining hall by loaning out lunch boxes. The number of lunchboxes needed was estimated based on a survey conducted and data from the dining hall collected over a period of 6 months. The Lunchbox Rental Programme (LBRP) was executed from 5th to 9th March, and 12th March, between 8 -10:30 am. We found that lunchboxes rental did not effectively reduce plastic bag usage and inconvenience was the primary reason. We concluded that the habit of a convenient lifestyle is accountable for the excessive consumption of single-use plastic disposables. As a future consideration, the convenience that the proposed solution entails should be analysed before its launch.

Event Organisers provide door gifts as they think that event-goers want and expect it. However, observations of campus events point to disposal without use of many item types. In this project, we investigated the importance of door gifts in attracting event-goers and the possibility of reducing such resource investment and wastage. With an online survey, 169 event goers, aged 18-65, were evaluated for their views and preferences for door gifts. Event Organisers were interviewed to understand why they choose to provide door gifts and if they were willing to accept sustainable solutions. The results suggested door gifts are not a critical factor to event-goers in choosing to attend an event and Event Organisers were willing to consider sustainable solutions. With the trend of receiving door gifts, however, door gifts reduction, first through sustainable alternatives could be attempted gradually over time.

Empowering campus communities to participate in and influence decision-making processes that ultimately affect their lives is critical for sustainability (Cervoni et al. 2008). As NUS is at a strategic phase in setting up a sustainable campus, student input can and should be incorporated in meaningful ways. Our project explored stakeholders’ perception and awareness of ‘WaterSmart’ and sustainable landscapes to test a systematic approach for participatory design solutions on campus. Using the RVRC landscape as our case study, we conducted a quantitative survey to examine residents’ perception and awareness of ‘water smart landscapes’ as a sustainable alternative. Our results highlighted that staff prioritised functionality while students prioritised aesthetics. Sustainability was not a high priority for either stakeholder group. The respondents also scored low on awareness of sustainable alternatives. We recommend information sharing as a key component of the participatory design process for the successful implementation of campus infrastructure improvements.

Getting millenials to adopt sustainable food options, in spite of higher costs, is possible (Gibbs A, 2016). Our project tested this finding in NUS Residential Colleges, with our target audience being RVRC residents. Using a combined methodology of an online survey, a pilot test and an awareness campaign for adopting sustainable food options, we evaluated if consumers’ perceptions and behaviours coincide. Our awareness campaign included digital posters and WhatsApp reminders. Survey results ranked cost and taste of food over sustainability. We also found that between ‘health of food’ and ‘taste and cost of food’, the latter was more valued. This matched the perception survey results. However, the results of our pilot test conducted at the RVRC dining hall by offering sustainable menu options indicated otherwise. This contradiction could be due to many external factors. Our project provides some valuable insight about attitudes of students with regards to sustainable eating but it cannot be considered conclusive. We recommend a more extensive pilot test to obtain more meaningful results.

Travelling on the NUS campus can involve riding shuttle buses, walking, cycling etc. However, these options are coupled with the challenges of long distances, uneven terrain and tropical climate variability. Our project aims to study the feasibility of an alternative walking option, an elevated Forest Canopy Walk, around the ridge to promote walking and reduce transportation burden. In particular, our project focuses on determining the most viable access points for such a pedestrian link. Our methodology included field work to measure existing pedestrian travel times, analysis of campus topography and a visual inspection of the proposed access points for the loop. Student willingness to walk was a key criteria that we assessed, and substantiated from the work of our collaborating teams. Our feasibility study ended with positive results and we propose Science Building 4 (S4), Computing Centre 1 (Com 1), Central Library (CLB) and Ridge View Residential College (RVRC) as the four most viable access points for the elevated pedestrian loop.

Green spaces are varied, ranging from manicured gardens in urban towns to untouched primary forests. More importantly, wild greenery in unprotected areas are planned to be removed to make space for developments, destroying habitats and endangering many species of wildlife. Comparing between different perceptions of wild and manicured spaces, the lack of objection to such plans might be because wild greenery and its importance is not well appreciated. Hence, the project aims to raise the level of appreciation using a walking tour conducted around NUS. The appreciation level generally increased by 10% and carries potential as part of a curriculum.

Singapore alone consumes about 2.1kg coffee per capita and the spent coffee grounds (SCGs) produced brings about significant waste disposal issues. By tapping on its high nutrient and energy content, SCGs can be added into composts and be used to promote plant or fungi growth. To further minimise household waste, the group investigates the idea of creating modular mushroom growth kits using SCG and growing in containers made from household wastes (plastic bottles and milk cartons). The team also plans to find out optimum conditions for mushroom growth to occur indoors and share it with households.

Water security has always been Singapore’s priority due to its lack of natural resources. This project focuses on re-emphasizing the importance of water conservation by spreading awareness through the use of education materials. Literature has shown that water conservation habits should be cultivated early, and that children learn better with hands-on activities as compared to structured teaching. As such, we have narrowed down our target audience to pre-school children, and chosen the approach of an interactive workshop. The 30-minute interactive workshop comprises the of 1. a Pre-workshop, Post-workshop and Review Survey, 2. Water Saving Demonstration, 3. a Maze game, and 4. a Poster Pledge. Our review survey tested the effectiveness of our workshop by measuring the knowledge retention rate of the pre-schoolers, while our poster pledge will serve as a constant reminder for them after the workshop ends.

Whenever we go shopping for groceries, we place enormous amounts of emphasis on the appearance of food products, completely neglecting ugly fruits and vegetables, as though they are not nutritious. This behaviour is not only observed in consumers, but even food importers who reject food based on appearances. Our project examines the current state of ugly produce in Singapore and attempts to understand the general perceptions of wholesalers and consumers towards them. Through the use of surveys, observational studies and interviews, we aim to investigate the perceptions of Singaporean wholesalers and consumers towards ugly produce, as well as the possible effectiveness of pricing to influence consumers’ purchasing habits. From our study, we question the assumption that ugly fruits and vegetables are present in Singapore and emphasise that “ugly” is a highly subjective concept.

Greenwashing is the practice of making a misleading claim about the environmental benefits of a product, service, technology or company practice. A company may appear to be more environmentally friendly and advocate for sustainability, but all these may just be a façade. Greenwashing can do more harm than good if consumers purchase products that are not genuinely green, misleading them from supporting businesses or products that are actually environmentally sustainable. Are notebooks promoted as eco-friendly made from recycled paper? What is the source of this “recycled” paper? This project aims to identify the extent greenwashing among RVRC students and develop a campaign to educate students on the phenomenon of greenwashing. The project seeks to gauge students’ awareness of greenwashing, the different forms of greenwashing and to determine if students are able to link these to the impacts of greenwashing on the environment, consumer behaviour, and so on.

There is an estimated 450 eco-labels across 25 industry categories, labels indicating that a product is environmentally-friendlier compared to similar products in the market. However, how effective are these eco-labels in influencing consumers to purchase a product? This project aims to determine whether the presence of an eco-label on a product would influence NUS students to purchase it over a similar product without an eco-label. If so, how much more are students willing to pay for the eco-friendlier option? Do they even know what the eco-labels mean? Before these questions are answered, how many of them even bother looking for eco-labels on the products they buy? This project seeks to understand how the demographics of different students affect their purchasing behaviour and to create awareness to reduce apathy and ignorance among consumers. This is done to maximise the influence the eco-label has on increasing consumer’s purchasing behaviour.

To achieve these aims, we conducted a survey to assess students’ knowledge on the issue. Half of the participants have good knowledge but they do not actively decide to purchase SPOP. We then conducted a focus group discussion to investigate the reasons behind this lack of action. The results show that participants do not think their consumption of SPOP will alleviate the negative impacts of consuming non-SPOP.

Consistently high visitorship to Bukit Timah Nature Reserve (BTNR) is more than the capacity it allows. This proved to disrupt the wildlife and erode pathways at BTNR. Hence, our project aims to reduce visitorship among all demographics. However, it might be difficult to implement our project. Using data from research papers and visit history from NParks, we adjusted the visitor quota depending on the time and the day. Analysing our survey results, 54% of those surveyed were open to the idea of a quota on visitors. Our results offer a viable option for the consideration the management of BTNR.

Using tree branches as hiking support endangers users and the environment. Sharestix aims to provide an alternative for tree vandals to rent our hiking sticks instead of using branches from trees as hiking support. In order to test its feasibility, we rented hiking sticks for free during 2 weekends at BTNR and gathered their opinions. All 20 users resoundingly agreed that visitors will be discouraged from vandalism with the implementation of Sharestix and it had improved their climbing experience. While we cannot completely prevent vandals, the convenience of our stick sharing system can serve as a disincentive for vandalism.

Want Not, Waste Not is a project focused on establishing the causal relationship between aggressive marketing in supermarkets and food waste amongst Singaporeans aged 19 to 25 years old. Through researching extensive literature and our methodology, a positive association between products that are aggressively marketed, and products subsequently wasted by consumers is apparent. Our project aims to reduce the wastage of food by educating the consumers about aggressive marketing and its link to food waste in hopes that they don’t fall prey to these strategies. Through a simulation pilot study, we evaluated the effectiveness of our methods; gauging our respondent’s response to aggressive marketing techniques after implementing our education campaign.

Industry Advisor: UCI

The main mode of transport in NUS is the NUS Internal Bus Service, which some 69% of the campus community rely on to commute in campus. High passenger load/overcrowding during peak hours is problematic and difficult to resolve. The culmulative carbon emission from the estimated 31,200 trips per school semester is also significant. One approach to alleviate the situation is to encourage commuters to cycle as a means of getting around campus. However previous studies also show that implementing such schemes can be challenging. This project aims to assist University Campus Infrastructure in collating crucial information, namely time and elevation changes, on various possible cycling routes, which could be used as alternatives to buses or walking.

Academic Advisor: Dr. Chua Siew Chin
Industry Advisor: NParks

Despite losing almost 90% of the original vegetation, about 50% of Singapore today is still vegetated. This in part is due to Singapore’s efforts in promoting manicured parks. Manicured areas serve ecosystem functions such as lowering surrounding temperatures and also provide recreational facilities for park users. Our project examined how manicured areas in Singapore Botanic Gardens (SBG) affect human thermal comfort. We examined how relative humidity and air temperatures of two manicured areas that are 1. elevated, 2. close to water bodies, compare to a control that is an open manicured area with minimal shading. Our data came from datalogger installed at the three areas. We also conducted survey on thermal comfort of park users at the same sites and analyzed the correlations between the data with the user comfort data. Our results help to determine key factors influencing microclimate within the urban park and direct in future planting designs.

Academic Advisor: Ms. Sadaf Ansari

The sprawling NUS campus can be traversed using a combination of internal shuttle buses, bicycles and covered walkways. However, the steep forested ridge cutting lengthwise across the NUS campus increases travel time for pedestrian movement. Our project explored this limitation as an opportunity for a creative pedestrian solution by proposing a Canopy Walk across the ridge. Of the many variables that needed to be evaluated, we chose to focus on three – existing terrain, tree distribution and minimising disturbance to the ecology. We began work with generating a detailed terrain map for the campus using the Quantum Geographic Information System (QGIS). This was coupled with field visits to confirm the accuracy of the topography model as well as the tree locations and sizes. Using secondary data to extrapolate our findings, we finalised one potential route for the elevated pathway, and represented it using a physical model. Our design also assessed inevitable ecological/practical challenges, which would benefit from a more detailed study.

Recent research (Cairo, A. 2011; Mcmillin, J., & Dyball, R. 2009) shows that student-participation in driving campus sustainability endeavours leads to dynamic projects and increases overall campus commitment towards sustainability. Our team decided to verify if these findings were applicable to the context of the RVRC module GEQ1917. We explored past and current student projects for the module to identify key advantages and constraints faced by the students in the implementation of their sustainability projects. We constructed survey questions based on research literature regarding this topic, and deployed them to both students and industry advisors involved in GEQ1917 projects. We analyzed the results to obtain an overview of these projects, as well as chart trends in student commitment towards sustainability and key benefits and constraints within student implemented sustainability projects. Overall, our secondary research and primary data both corroborated that the main advantage of student involvement in sustainability projects is increased awareness towards sustainability, while the constraints of these projects ranged from a lack of interest to time limitations. We also noted that most projects led to an increase in overall student sustainable behaviour and commitment.

Marcia Lee Tjie Yi, Ong Jing Xiang, Tan Jia Yih Tiffany, Yeo Guo Hong, Zhang Ruichun

Academic Advisor: Ms. Sadaf Ansari

For thousands of pedestrians, undulating topography and less than ideal thermal conditions make walking along the roadside and sheltered walkways at NUS undesirable. Considering that the university is at a strategic phase in setting up a sustainable campus, increasing walkability would contribute significantly to that goal. Our project investigated thermal comfort on a variety of existing campus pathways. We measured airflow, temperature and humidity along the vehicle route and the ‘yellow corridor’. We mapped and compared this data to conditions in the Kent Ridge Forest to ascertain if the tree canopy significantly mitigates/changes the pedestrian experience with respect to thermal comfort. In our assessment, the forested ridge located lengthwise across the campus could provide a viable alternative walking solution, allowing users to travel on a route that significantly reduces walking distance and commute time. Based on our findings, we recommend that campus improvements for walkability should explore this potential solution in greater detail.

With increasing wildlife encounters due to rapid urbanisation, our project aims to increase awareness on the wildlife in campus so as to reduce human-wildlife conflicts. A ground survey was conducted to learn whether residents have seen or know the names of the animals around them. Our findings showed an appalling lack of awareness for them. Our campaign solution was to personify these animals, create infographics and engage RVRC residents with the iSpy Challenge. Our campaign showed a marked increase in awareness level, testifying the efficacy of integrative and personable strategies in bridging the gap between humans and wildlife.

Our project seeks to identify the incentives that encourage individuals in NUS to travel via cycling. We conducted a general survey on 276 respondents in NUS to identify the difficulties and incentives raised by the NUS community. Based on the preliminary results, we proceeded to carry out our Grab-Y-Bike (grab your bike) campaign emphasising on convenience and monetary rewards respectively. The campaign was a positive one, with a greater proportion having a preference for saving time as an incentive for cycling. Hence, rather than having an overarching biking campaign, a targeted campaign with emphasis on convenience is recommended for better results.

Food waste occurs in many stages of the food supply chain. Our project focuses on marketing practices in supermarkets in Singapore, and its relation to food waste. Focusing on marketing practices on non-perishable food items in supermarkets, we look to answer the following questions: Is there a relationship between marketing and food waste? Do the marketing practices spur consumers to purchase more than needed, and therefore result in food waste? Are there differences in responses across different age groups? We zoomed in to three marketing practices: (1) tags on price displays, (2) “Buy 2 Get 1 Free” promotions, and (3) large packaging.

Soil is one of the biggest terrestrial carbon sinks in the world. Knowledge on factors that contribute to the success of soil carbon storage has far reaching benefits for the environment in terms of mitigating the imbalance of atmospheric CO2. Our project seeks to contribute data to this emerging field by studying the relationships between the varying types of vegetation and the differences in levels of soil carbon beneath these vegetation.  Soils are sampled from various green spaces on campus, and analysed for total organic carbon and total inorganic carbon levels. Through the findings of our project, we hope to recommend the types of urban vegetation that are more efficient in sequestrating soil carbon to urban developers and planners, thereby maximizing the carbon storing potential of future green spaces in cities.

Our research investigated the relationship between the density of the canopy cover and the recruitment of three secondary forest species in Singapore. We propose that the density of the canopy cover and the growth of secondary forest species is likely to be related, as the density of the canopy cover would affect the microclimatic variables of temperature and relative humidity, which in turn would affect the growth of the secondary forest species that we are interested in. We hypothesize that a denser canopy cover would result in a weaker understory regeneration of the secondary species. A better understanding of this research topic could be of significance to Singapore’s urban planners planning to incorporate natural growth and regeneration of secondary forest in new development and conservation plans.

Food waste is a growing concern in Singapore. In fact, food from households amounting to 200 million dollars is wasted annually. In addition, based on a survey by NEA, one of the top two reasons for household food waste is due to forgotten refrigerated food. Hence, we propose a phone app which comprises of five different features, which aim to specifically reduce refrigerator food waste in households. After conducting pilot tests using a prototype app, we gathered data on the perceived effectiveness and likelihood of usage of each individual feature through our survey. Furthermore, we conducted an interview with a senior representative from Cold Storage to gain insights about the food industry and to validate the feasibility of our app. With the favourable responses and feedback gathered, we have created a working and marketable Android app.

Food waste has become a prevalent topic of sustainability, having caused high levels of economic and environmental damage. Food waste occurs when edible food is intentionally discarded by consumers after they fail to plan their meals properly and store food till it spoils or goes past the expiry date. The biogas digestion machine was widely used in other countries such as the United States, India and Israel, as part of their local sustainability programs the concept was hardly known nor utilized in Singapore. Hence, We provide a solution to the increasing amounts of food waste in Singapore, by building a low cost Biogas Digestion machine. This machine could be installed within households to recycle food waste into usable biogas that could be used for cooking.

There is a significant economic and sustainable opportunity in reducing food waste by consumers. The aim of this project is to go beyond posters to make the consumer feel they are actively contributing to this reduction. Our group has created a Telegram Chatbot to encourage students to reduce food waste. This Chatbot helps to track data of each person such that they are able to view their personal and group statistics. It is hoped that by making participants more aware about the amount of food waste they generate, they will make a conscious effort to reduce their food waste. The food waste was manually measured, with avoidable food waste being separated from unavoidable, and the data was uploaded to a spreadsheet. Our group set a benchmark of 100g of daily food waste per participant and after 3 weeks of pilot testing, we hope that every participant will achieve this goal.

Since the arrival of dockless bicycle sharing systems in NUS, indiscriminate bicycle parking has become a nascent problem, posing potential safety hazards and aggravating clutter on campus. Currently, the onus has been on operators to remove indiscriminately parked bicycles. Our group’s review of current literature revealed a paucity of user-focused methods to reduce the likelihood of indiscriminate parking. We conducted a survey identifying lack of awareness of bicycle parking zone locations, and lack of motivation to park responsibility as key factors in users choosing to park indiscriminately. Thereafter, we designed two types of prototype signages to determine its effect on creating proper bicycle parking behaviour.

Singapore is well known as a Garden City because of our intensive urban greening efforts. Green spaces in Singapore range from manicured parks such as Singapore Botanic Gardens, to nature reserves such as Bukit Timah Nature Reserve. Each of these green spaces serve different functions, often with the users in mind. Often neglected is the ecosystem functions of these green spaces, which include mitigating urban heat island effect, storing carbon, regulating hydrologic processes and improving air quality. Unfortunately, the ecosystem functions of these green spaces might not be understood and hence under-valued by the public. Using Bukit Timah Nature Reserve and Botanic Garden as specific examples of natural and manicured landscapes respectively, this project seeks determine the public’s perception towards these green spaces, and their awareness of the different ecosystem functions provided by the two examples. Our findings reveal the public’s misconception on ecological functions and highlight the need to educate them on this.

The projected increase in global energy demand for decades to come has been a great concern for many, and it shows no signs of cessation. One possible explanation for this is the link to greater demand for air-conditioning for cooling of buildings. However, plants can be greener alternatives that also provide cooling effect to the surroundings. By taking temperature readings and comparing it across different proximities between building and greenery, our project aims to assess the extent of cooling effect greenery has on indoor temperatures. We aim to study the effectiveness of cooling on two types of greenery – green wall installation and natural forest. Our data from four locations across NUS generally show that the closer the greenery is to the building, the lower the temperature. Our findings fit in nicely with our expected outcome of proving that greenery nearby buildings can be a good substitute for air-conditioning.

The project focused on designing a World Water Day campaign to re-emphasize the importance of water to tertiary students staying on campus, with the tagline: “Make Every Drop Count”. Targeting students staying in Ridge View Residential College (RVRC), the project monitored the water usage between different blocks in RVRC, to determine the effectiveness of different campaign methods. We compared three methods: posters, instant and delayed feedback regarding students’ water consumption. Our project spanned across February to March 2018. We hypothesised that instant feedback will be the most effective campaign method as residents will receive timely feedbacks about their personal water usage, and this was reflected in our findings. After our project in RVRC, we hope to be able to introduce the best survey method to other Residential Colleges and Halls to promote water conservation in all NUS campus.

Academic Advisor: Ms. Sadaf Ansari

For a tropical setting such as NUS, ‘Thermal Comfort’ is the most important criteria that impacts student behaviour and perception of walking on campus. Adopting a quantitative framework of assessment, we measured trends in the airflow, temperature and humidity for three different ‘design conditions’. Two of these conditions exist currently – the uncovered pedestrian pathways along roads and the sheltered Yellow Corridor. This data was compared to conditions along an elevated forested setting – measured at the Kent Ridge Forest on campus and at the Hort Park Tree Top Walk. We analysed the data to determine trends – with a focus to ascertain if the tree canopy significantly mitigates/changes the pedestrian experience with respect to thermal comfort. Our results indicate some meaningful trends for temperature, while there were mixed results for humidity and wind speeds. Based on this, we recommend the undertaking of a broader study with greater variation in weather patterns to confirm our initial findings.

The NUS campus has several high maintenance low-use landscaped areas. Our project, a case study of Lovers Park (CLB, NUS), was aimed at identifying key design elements that can assist in transforming such spaces to high-value landscapes that are more relevant to user needs. Our field work used timelapse videos, to identify and evaluate space use patterns. Our initial results indicated that the park is under-utilised, possibly due to location and limited flexibility in its use. This was corroborated in an interview with a long-serving staff in CLB. Next, we quantitatively measured and analysed user perception of the park, and their receptiveness to alternative design solutions, through a survey. Results indicated weather variability, poor maintenance, and pests as key deterrents in the existing design. Our analysis also indicated that value-added functionality plays the determining role in the use of open spaces from a student perspective. We recommend that the design and purpose of outdoor spaces on campus should be re-directed flexibly to cater to evolving stakeholders needs.

Student requests for increased frequency of NUS shuttle-buses have been common in recent years, as evidenced in previously conducted GEQ projects. In line with NUS’s plans to create a sustainable campus, it is crucial to explore ‘greener’ alternatives to transportation, such as walking. Our project assessed the potential impact of improved connectivity and access to nature on increasing campus walkability. Our research identified three key criteria; 1) student perception towards walking on campus, 2) key determinants for campus walkability, and 3) students’ preferences for walking in nature as compared to built spaces. Data was collated through an online survey targeted at a convenience sample of NUS students. The survey also mapped students’ preference for transport around campus, current walking habits and willingness to increase walking on campus. This data provided a comprehensive overview and one of our key findings was that improved pedestrian network connectivity predicted longer walking distances and an increased likelihood of walking as a means of transportation.

Educating NUS students on the proper behaviour when encountering wildlife on the NUS campus through a workshop. The goal of the workshop is to increase students’ knowledge and raise awareness on the importance of three groups of wildlife (snakes, insects, birds) through interactive and engaging activities. Approximately 60% of the participants who attended the workshop learnt more about interactions with wildlife on campus. It is thus recommended to implement the workshop as part of the RVRC Programme, and possibly other residential colleges, to allow students to instil correct behaviours and responses when interacting with wildlife.

Coffee consumption generates significant waste as spent coffee grounds (SCG) are often incinerated and discarded in landfills. Little has been done to address the waste issue in Singapore, despite rising coffee consumption. Our project seeks to use composting as a means to reuse SCG. A group of home gardeners were surveyed and a majority (>70%) have open attitudes and knowledge about SCG composting. An experiment was also conducted using kang kong (Ipomoea aquatica) to determine the effect of SCG compost on plant growth. The results demonstrated the possibility of using SCG compost to grow plants.

Urban development tends to come at a high cost to the natural ecosystems, often resulting in loss of forests, biodiversity and ecosystem functions. One example of this is the disruption of the environment due to anthropogenic sound pollution. In this project, we determine the extent noise pollution is mitigated by surrounding vegetation and determine a suitable buffer distance between natural and man-made environments. Using Rifle Range Road as the experiment site, the noise level is measured at different distances from the main road into the surrounding forest, at different levels of forest densities. Comparing the findings to existing literature on the acceptable noise levels for wildlife, the project will attempt to determine a minimum buffer distance for sparse, medium, and dense vegetation, such that the anthropogenic impact on the surrounding ecosystem is minimized.

Urban development has contributed to a loss of forests, biodiversity and ecosystem functions. In Singapore, green spaces form half of the vegetation cover, whilst secondary forests form the other half. Researchers highlighted potential socio-cultural, socio-political and biodiversity impacts from the loss of secondary forests and how Integration of it into future landscape designs might reconcile development and forest conservation. Natural foliage is barely integrated in ecocentric landscape design. We shall investigate the amount of foliage/greenery needed to achieve optimum light conditions for wildlife protection. Previous study calculated that optimal night lighting level experienced by wildlife ranges from around 1×10^-4 on a moonless starry night, to 0.1-0.3 lux around full moon. However, in Singapore, light intensity of shopping malls is 10-20 lux. Results collected could be used to help landscape designers integrate secondary forests into future designs to protect nocturnal wildlife.

Research has established that campus landscapes can have significant psychological appeal and health benefits for students (Mascarelli 2009). The NUS Kent Ridge Campus is located amidst a dense urban setting and faces severe land constraints. Our project evaluated stakeholder use and values about the existing campus landscape to identify potential improvements. Using a literature survey, we narrowed the assessment criteria to three main factors: convenience of use, natural elements in the landscape and user-designer mismatch. Primary data was collected from a convenience sample of students in a two-step user survey, with a selection of campus photographs for three case studies. The first survey gathered insights on students’ attitudes and use patterns. The second survey gathered targeted feedback on improvement options using results of the first survey and are framed as recommendations for campus planning. Future research could explore differences across age, gender and field of study to develop a stratified understanding of stakeholder values.

Our project assessed built-environment criteria such as amenities, shelter, connectivity, distance and aesthetics with students as the target group. This is because they have higher walking needs and frequencies than staff, and form the largest fraction of stakeholders on campus. We identified two routes for our study based on their student traffic numbers. Both quantitative and qualitative responses were obtained by means of online and on-site surveys. Our results indicated that shelter was the most significant determinant, followed by the duration of walking and the presence of stairs. Among students who preferred the unsheltered routes, terrain and shorter travel distance were key criteria. Based on our findings, future campus improvements should assess student preference for shelter, level terrain and shorter walking distances for more impactful solutions.

Global awareness of sustainability has risen in recent years, but the uptake of sustainable behavior is lagging behind. More needs to be done in the field of sustainability marketing, with regards to understanding people’s motivations for adopting sustainable behavior. The millennial generation, who show high levels of environmental concern and form a large part of society, are prime for such marketing. Our project examined three core values that drive millennials to adopt sustainable behavior, using the platform of food waste at RVRC. First, we identified three critical millennial values as part of our literature review. We evaluated these criteria with a quantitative survey of students’ opinions on marketing techniques. Then, to test and verify our findings, we launched a marketing campaign at the RVRC Dining Hall, and measured the food waste levels before, during, and after our campaign. Lastly, we followed up with a post-campaign survey to ascertain students’ reception to our campaign. We have assimilated our findings into a meaningful understanding, to be shared with MEWR.

Academic Advisor: Mr. Lim Cheng Puay

Singapore is a highly urbanised country with 100% of her population living in urban areas. Despite this, there is still about 47% green coverage and primary forest and wetlands gazetted as nature reserves. We have a rich assemblage of flora and fauna, with still new discoveries made; more than 480 new species of plants and animals have been discovered in Singapore over the last five years (Lin 2017)!  This greenery was no accident. Besides its aesthetics and ecological benefits, green spaces have been touted to improve the psychological well-being of its users (Muscara and Saegert 2007). Yet green spaces are not uniform, they range from untouched primary forests to manicured parks and gardens found in urban towns. This project aims to measure how undergraduate college residents perceive green spaces around them and the extent to which the students are comfortable with ‘wild greenery’ as opposed to ‘manicured greenery’.

Urban spaces play a significant role in causing injuries and death to wild birds. The proliferation of highly reflective glass facades and extensive light pollution all contribute towards resident and migratory bird casualties worldwide.  Singapore, a highly urbanised metropolis, is located beneath the East Asia-Australasia Flyway, a major migratory route for over 3 billion birds. The impact of the city on the survivability of wild birds poses a significant threat to its populations. Understanding and mitigating the sources of urban bird mortalities is thus a critical component of maintaining urban sustainability. Save Our Skies is a citizen science programme designed to help with data collection on the issue of bird and building collision. The programme hopes to ultimately produce a robust set of data on the state of bird/building collision in Singapore, thus providing convincing arguments and useful observations in the push for bird-safe building design regulations.

This project aims determine the sources of marine litter in Singapore’s shores. In this study, by surveying a sample of Pasir Ris Beach, located on the east coast of Singapore, we were able to identify various origins of marine debris from January to March. Our data suggests land-based sources, such as convenience stores and supermarkets, as the main origins of the marine debris found along this stretch of the beach. This projects marks one of the first steps into a new method of tackling marine debris throughout Singapore’s shores

Food wastage has always been a problem worldwide but what we have come to realise is that Ugly Food is being wasted unnecessarily. Due to cosmetic reasons, imperfect fruits and vegetables do not reach the hands of customers and even if they do, consumers are afraid of how they look ‘abnormal’. Our team aims to tackle this problem at the consumer level, changing their mindset and showing them that these fruits and vegetables are perfectly edible although physically imperfect. By doing so, there will be a cascading effect on the supply chain, where the different middlemen would be more willing to not throw these fruits and vegetables away as there is consumer demand for it. We have done this by reaching out to a local farm in Singapore and working with them on a campaign.

This project aims to find out the trends in plastic bottled water usage among tourists in Singapore through a better understanding of their mindsets. From street surveys at tourist locations, we found out that convenience was a major factor motivating tourists to buy plastic bottled water instead of bringing their own water bottles to refill. The results also revealed that age was another major factor which affected water consuming habits. Surprisingly, the country of origin of the tourists had little impact on their behaviour towards plastic bottle consumption. Eager to find out more? Join us in discovering the reasons behind the behaviour of tourists which can hopefully provide us with potential solutions to reduce plastic bottle usage in Singapore!

The motivation of our project is to propose the best way to encourage awareness and behavioural change in millennials. Our project aims to investigate the effectiveness of existing sustainability campaigns in marketing sustainability to millennials, and to propose recommendations on the type of marketing strategies which will appeal to millennials. To do this, we decided to zoom in on raising the awareness of climate change in millennials, in line with the Year of Climate Action 2018, and more specifically on reducing plastic and paper waste. Based on our analysis of past and existing campaigns on sustainability, we came up with several initiatives targeted at RVRC students, namely posters, website, social media account, and a waste reduction challenge. From the feedback and data gathered from our campaign, we are able to conclude that the most effective marketing strategy points to direct engagement and peer influence, rather than social media.

Academic Advisor: Ms. Wong Kah Wei

Straws are given out with virtually every drink you purchase. Plastic straws are among the top 10 marine debris. More than 6 million straws were removed from coastal cleanups (Montgomery, 2014). Straws are made of petroleum plastics. The plastic straw production process contributes to global warming as well as fossil fuel depletion. Straws which are disposed end up in landfills and dumps which have a great impact on the environment. Straws that end up in the oceans pose a great threat to marine life who consume them by accident (Scher, 2016). This staggering amount of straws polluting the environment prompted us to find out the feasibility of reducing straw usage in RVRC dining outlets. To better understand our high straw usage, we plan to investigate the reasons students choose to use straws. This will help us decide on the best approach to tackling this problem. We intend to draft a survey to gauge the awareness among the RVRC students of straw usage. Based on the results, we would craft our strategies to most effectively discourage the usage of straws, starting with retailers where RVRC food vouchers can be used. Our group has narrowed down to target Royal Bistro as our industry partner due to their willingness to work with us on this project to become a more sustainable dining outlet.

Imagine an average National University School (NUS) student. He studies Arts and Social Science and lives at Ridge View Residential College (RVRC). He wants to participate actively in the NUS community. He just so happens to be wheelchair bound. Should this affect how the student participates in NUS? NUS strives to be an inclusive environment as evident in its infrastructure and services which support the needs of the wheelchair bound students. By comparing the functionality and effectiveness of existing campus infrastructure and services for wheelchair bound students, our project aims to determine if this existing support is sufficient for wheelchair bound students to be independently mobile in NUS. We will be critiquing the theoretical side of the issue through practical assessments. Our proposed methodology will include using pre-existing information and sources, social experiments, gathering of data through focus group discussions and interviews with current NUS wheelchair bound students, staff from Disability Support Office (DSO) in Office of Student Affairs (OSA) and Office of Facilities Management (OFM), NUS Enablers and RVRC. Our data analysis and insights will give our group more knowledge of the issue, thus, leaving us in a suitable position to recommend improvements to existing policies and infrastructure; and suggest alternative approaches. We strive to partner NUS stakeholders in creating a more inclusive campus in which all NUS students are empowered to actively participate in the community!

Universities provide students resources ranging from transportation to the use of paper. Paper is used in all aspects of academic learning, ranging from books to lectures notes and assignments. According to a study conducted at the Minnesota State University, approximately 2.4 billion pages of paper were used in an academic year. A third of the papers were discarded instantly, while the remaining were neglected. Apart from filling up landfills, paper also contributes to the release of Greenhouse Gases such as methane. Methane traps heat 21 times more effectively than carbon dioxide. In Singapore, 1.2 million of paper waste is generated of which only, 51% of it is recycled. With this worrying trend of paper waste, we decided to focus our project on recycled paper generated by RVRC students. The scope of narrowing our project to this local level is to manage the constraints of limited manpower and to collect data efficiently. Our project aims to incentivize the recycling of paper by showing how much money could be generated from recycled paper which is sold. The money collected from the sale could be used to sustain this endeavour. To test out our idea, we decided to use RVRC as a platform for research and data collection.We intend to create our own recycling points to improve the locations and frequency of bins. We will collect the recycled papers disposed by RVRC students to estimate how much paper could be collected regularly. We will quantify how much paper is disposed in bins through a weighing system. We propose to be the middleman between recycling companies and RVRC students. Additionally, surveys will be conducted prior and after the test run to gauge and obtain feedback on this initiative. With data analysis, we hope to draw insights to develop a conceptual plan to show how paper sold to recycling paper companies is an option to incentivize people to recycle paper.

Industry Advisor: Ms. Karen Ho Lye Ying (UCI, NUS)

Our project focuses on rain harvesting due to the increasingly scarce water supply and rising water prices. Singapore’s water treatment process is also high in cost and energy. Rainwater harvesting and direct usage can thus help to conserve potable water and reduce the cost for treating potable water. Although the Singapore government has lifted the ban on rainwater collection, rain harvesting is still uncommon locally, the Changi Airport being one of the few examples. Our group believe that there is potential in rain harvesting and wish to implement it in RVRC, to test the feasibility of the system in reducing water use in a small-scale setting. We also aim to educate and demonstrate to the wider RVRC community that rainwater harvesting is a viable method to supplement the existing water supply. This will be done through improving and customizing the current rainwater collection methods for specific usage. For our project, we positioned the water harvesting system at Block C and will use the water collected to water the RVRC edible garden. We will also be measuring the amount of rainwater collected using a water meter in order to quantify water inputs and outputs. To prevent debris and mosquito breeding, we installed mosquito nets at all the openings of our tank. We also plan to put up infographics and posters about our system around the college compounds in hopes of drawing attention to the rain harvesting system from the RVRC student population. Our setup will serve as a first prototype for subsequent rain harvesting systems in RVRC.

During a school year, NUS students eat a majority of their meals in NUS canteens. Currently, NUS promotes healthier eating by requiring canteen stalls to provide calorie information for each of their dishes. However, calories are just one part of health equation; a diet needs an array of nutrients in order to be considered healthy. While the Singapore Health Promotion Board has healthier choice labels and healthy plate options to help people make better diet choices, it remains difficult for people to make healthy decisions when eating out. Our group hopes to bridge the gap between the available information and the food decisions NUS students make, by narrowing down the options to a suggested weekly menu of healthy dishes. This project will provide a healthy meal plan based on the food dishes at the YIH canteen. We intend to use the Health Promotion Board nutritional guidelines as a baseline definition for a healthy diet. Following which, we will survey a sample of NUS students to assess their eating habits in terms of how often they eat out, and their main considerations for food choices in order to improve our meal plan. Then we will use consolidate the nutritional information from the Health Promotion Board and other sources, to construct meal choices that people could use for a week. After which, we will do a pilot study on how NUS students might respond to such a meal plan, and the extent that such a meal plan promote healthier meal choices among students. At the end of our study, we would conclude our findings and come up with possible extensions of this project.

Fossil fuels such as oil and natural gases are finite resources that are not only rapidly depleted, but burning fossil fuels is also detrimental to the environment. As such, there is urgency to switch from fossil fuels to renewable alternative energies. Among the various renewable energies, solar energy is deemed the most promising solution in Singapore, given the island’s tropical climate and small land space. However, renewable energy usage in Singapore is not widespread due the perception of high cost and greater inconvenience. In line with RVRC’s theme of environmental sustainability, our group intends to test these perceptions by studying the actual feasibility, in terms of cost and site’s suitability, of using solar energy within the college. Our project will evaluate the cost and site suitability of replacing existing conventional halogen light bulbs along RVRC walkways with solar-powered light-emitting diode (LED) light bulbs. Given cost limitations, our team will focus on small-scale implementations, targeting the replacement of a single light bulb with solar lamps, and measure the savings in cost and energy. We would then extrapolate the results to college-scale implementation. To evaluate the site suitability for solar panel installations, we intend to model the amount of sunlight exposure in different areas of RVRC using SketchUp, a software widely used in electrical industries and recommended by our industry advisor from SERIS.

NUS shuttle buses have always been a convenient transportation for students and staff to travel within the big university campus (150 hectares). For efficient movement between faculties, the bus are students’ only convenient transport option. Furthermore, with rising enrolment numbers annually, there is a strain on the internal shuttle bus system, which culminates in overcrowding and increased fuel consumption. To cater to the rising transportation demand, more buses can be added but it would result in worsening air quality. To reduce the pressure on the NUS internal shuttle bus service, cycling presents itself as a transportation alternative to buses. In this project we aim to determine the feasibility of cycling in NUS. For our pilot study, we intend to test if cycling is a feasible mode of transport in NUS. We will be looking at areas such as timing, distance and safety between designated locations. We will also survey participants after they have tried out the bicycles to obtain user feedback. It is hoped that this study can contribute to the planning of a sustainable transport facility in NUS.

Transport is a key sector that requires a more sustainable approach. 14% of all global CO2 emissions in 2014 were attributed to transportation (Environmental Protection Agency, 2014), a figure that is higher for developed countries such as Singapore. A similar issue is observed in the National University of Singapore (NUS), as students prefer to use the shuttle bus instead of walking. With a growing student population and limited transport infrastructure, this leads to issues like overcrowding of shuttle bus during peak hours and contribution to green house gas emissions. To resolve this problem, our group will design a mobile application aimed at helping students navigate around NUS campus. The prototype will be targeted towards Engineering students in the college, and the application’s effect on user behavior will be quantified using surveys administered before and after project implementation. Our group hopes to have a better understanding on the behaviors and attitudes with respect to sustainable transport and the relationship between infrastructure and behavior. It is hoped this data can be used in applying effective methods to encourage more students to consider walking in Campus.

Fast fashion is a phenomenon where apparel designs rapidly change to capture current trends. The high demand for such clothing is high, and greater consumption leads to higher disposal of these garments. In Singapore, only 8% of 156700 tonnes of clothes are being recycled in 2015. Textile waste is a significant environmental problem. Our initial studies indicate that current platforms for clothes recycling have low outreach. Therefore, we aim to explore reducing textile waste by clothing exchange through an online platform. The same platform will also educate visitors on the harmful effects of textile waste. A Facebook group was created to encourage people to trade and donate their clothes as well as to have greater awareness about the impacts of huge textile disposal. The group comprise of mainly young adults as they are the main age group that discard the most textiles. We are also collaborating with NUSSAVE to provide them with the donated clothes we collected through our platform. Success of the project will be measure through the participation rate of our Facebook platform and also by measuring the increase in awareness of textile waste through our education measures by conducting surveys.

Despite years of government-led efforts to promote recycling, the recycling rates in Singapore remain low. In recent studies, it has been found that one method of achieving higher recycling rates was to get people to come together to recycle, and make recycling a community-based activity. In light of this, our group decided to test if such a social event, Converge and Convert, could increase the recycling rates in Ridge View Residential College. We carry out our experiments on residents of Block A and B. Our event will be held at lounge A on Wednesdays on weeks 7 to 9, from 10pm to 11pm. During this event, Block A and B residents would bring their recyclables to the lounge. Our group would weigh and record the recyclables by their categories of plastics, paper and metals. To encourage participants to come for the event and to help nurture the recycling culture, the event will include mini games as well as an unknown prize to entice the residents. At the end of the events, comparisons would be made of the quantity of recyclables in the recycling bins at Block B, before and after the social events, to determine the project’s success.

Academic Advisor: Dr. Chua Siew Chin

Our Project “Straw Wars” aims to reduce plastic straw usage by providing alternatives to straws. Plastic straws are often regarded as disposal and insignificant. However, because they have a short lifespan of about 20 minutes, are widely used and non-biodegradable, plastic straws is actually one of the most common plastic waste and the top marine trash on Singapore’s coasts. While our preliminary survey on straw usage found that 66.9% of the respondents used straws because of convenience and not of necessity, it is likely difficult to alter people’s habits to not using straws. Thus, although it is hard to recycle straws, their demand would likely stay. Our group aim to replace straws with biodegradable ones. In our preliminary survey, our proposal of edible straws were well received by 70% of the participant. We will exploring two types of edible straws, one will be based on Gelatin or Agar Agar and the second will be flour based. We aim to distribute the straw prototypes and recommend our edible straws to users during the upcoming RVRC events. From there, we will be able to gather their responses and check their receptiveness towards our edible straws.

In Singapore, 7,673,500 tonnes of waste are generated every year, and a meagre 4,649,700 tonnes of waste are recycled (about 61%). This dismal statistic highlights the dire need for integrating Zero-Waste Schemes into existing Waste Management Systems. Especially on campus, the wastage of resources – food, paper and water, needs to be curbed with immediacy. In this project, we attempt to investigate the possibility of achieving a “Zero-Waste” Campus. Zero-Waste refers to minimizing the production of waste that needs treatment or landfilling. Hence, the adoption of a “Zero-Waste” scheme inherently involves the reduction in consumption and an increase in recycling efforts. We will be conducting a trial of the “Zero Waste Challenge” on a randomized student sample. This project has two aims. Firstly, to encourage individuals to discover environmentally friendly ways of performing day-to-day activities with the aim of producing zero waste during the course of one week. Through this, we hope participants will realise that it is possible to cut down on the waste we produce. Next, using the feedback gathered from participants from both pre-campaign and post-campaign surveys, we would pinpoint the difficulties that a typical student faces when trying to reduce the waste they produce on campus, and feedback to the school management on how it can better facilitate a zero waste lifestyle on campus.

Food security has been a long-standing issue in Singapore. With a dearth of local produce, Singapore is inevitably dependent on a large volume of imported fresh food. With no certain solution in sight, our group has decided to tackle the root cause of the problem – a lack of local produce. The scarcity and high lease-price of land in Singapore is undoubtedly a key reason that local farms are unable to expand their farms and increase productivity. Considering the issue of land scarcity, our idea is to promote farming in residential backyards with the use of an affordable and sustainable vertical farming system that is also easily constructed. With guidance from our industry advisor, we aim to create a prototype vertical farming system that is constructed out of recyclables and low-cost material. The prototype is designed to be suitable for mass production, making it accessible to all households. Inspired by IKEA, we will also design an instruction manual to aid buyers of our product in setting up their own vertical farming system. The main intent of these strategies is to make the product affordable, bringing our goal of having every Singaporean household to farm in their own backyard a step closer to reality.

The start of every new semester at National University of Singapore (NUS) sees new student residents moving into campus. This is typically accompanied by the discarding of previous residents’ belongings such as lamps, wi-fi routers, cooking utensils, irons and clothes. A large percentage of these discarded items are typically in good and re-usable condition, but are still consigned as waste. This trend is largely driven by a culture of convenience. Our project aims to take a simple step towards achieving a zero-waste society by reducing this source of preventable waste through a pilot test on Ridge View Residential College (RVRC) residents. The study categorises residents into three groups – local, international and exchange students. We believe that this classification effectively reflects their varied consumption and resulting waste habits. For example, exchange students typically purchase more new items than the other resident groups because they do not bring all items of daily necessity from their homes overseas. We will first conduct a survey and collect data from relevant campus agencies and the three RVRC student resident groups to identify the source and quantify the magnitude of waste. We will then review the impact of existing measures and suggest modifications and additional initiatives. Our main initiative is a system for reusing or renting commonly-needed items (such as hangers, stand fans, desk lights, room decoration, etc). Promotion of re-use of these items could be done through a bazaar at RVR Annexe or through an app. We will also explore the option of selling items to second-hand dealers or donating them to charities. To maximise effectiveness, our solutions would have to be convenient for the target student audience, thereby leveraging on their inherent culture of convenience.

Reusable bags, such as non-woven polypropylene bags and cotton bags, have been viewed as an environmentally friendlier alternative to single-use plastic bags as they can be made from recycled materials and are relatively durable. However, there is a lack of public awareness on the significantly larger carbon footprint left behind by each reusable bag as compared to that of each single-use plastic bag. In 2011, the UK Environmental Agency conducted a study on the environmental impact of various supermarket carrier bags and concluded that non-woven polypropylene bags and cotton bags need to be reused at least 11 and 131 times respectively to compensate for the higher carbon emission of each bag. In the National University of Singapore (NUS), reusable bags are often employed by student committees and organisations as a means to distribute freebies and pamphlets during school events such as the annual NUS Open Day. As a result of the high volume of such events on campus, students tend to receive and hoard a significant number of reusable bags with most of them remaining relatively unused. Therefore, we aim to maximise the use of each reusable bag owned by NUS students, because we see the need for all NUS students to set an example and take ownership of their own carbon footprint. Our group implemented a system in NUS where preowned reusable bags are collected, sanitized and then placed around the campus for reuse. We piloted this idea with the installation of ‘Feed Me’ reusable bag collection boxes in RVRC. This was followed by ‘Take Me’ reusable bag distribution boxes around the commercial areas of NUS, such as outside the NUS Co-Op. The results of our pilot will help to gauge if our idea can be implemented on a larger scale around other educational institutions in Singapore.

Green advertising refers to creative, or even interactive, designs that motivate behavioural change through various types of appeals, such as guilt and beauty appeal, aiming to steer consumers toward more environmentally-friendly behaviour. Since green advertising has not been a prevalent method in NUS, our project aims to evaluate its effectiveness in influencing consumer behaviour on the usage of paper serviettes in NUS bistros. Furthermore, this project focuses on a consumer-oriented, reductionist approach, because reduction is preferable to technological alternatives that have high embodied energy, which offsets any environmental advantage that technology claims to bring. Green advertising posters will be placed in three bistros for three weeks and compared against conventional infographic posters using the per capita rate of serviette consumption data. A quantitative survey questionnaire will be issued during the pilot test to the bistro customers to obtain their evaluation of the green advertisements. Qualitative feedback of the posters were also obtained. Through this evaluation, we hope to ascertain if green advertising is indeed effective in influencing behaviour and its possible implementation on a larger scale.

Using appliances contribute to the overall carbon emissions in electricity generation for Singapore. In RVRC, most of the clothing is dried using electrical tumble dryers due to lack of space and limited outdoor clothes drying facility. The reliance on tumbler dryers also contributes to the carbon footprint of RVRC and increased electrical bills. These necessitate the search for a more energy and cost-efficient method for laundry drying. However, alternative methods such as natural drying on available clothes racks are insufficient to accommodate all residents. As such, we propose a sheltered laundry drying facility, to promote the drying of laundry using natural wind. This aesthetically pleasing facility will have sufficient shelter for inclement weather, as well as a clothes line arranged in a rotational array to maximise space and accommodate more laundry. To speed up drying, the structure will be designed to capture maximum sunlight, and maximise wind and internal airflow. This structure would also be largely built out of sustainable materials. The successful use of this facility will greatly reduce reliance on electric tumble dryers, hence cutting down on energy consumption within the College. It also removes the cost of drying for the residents, and cuts down on energy bills for the College.

Textile waste poses a significant environmental problem in affluent countries. In Singapore, more than 150, 000 tonnes of textile waste was discarded with only 8 percent recycled. This project explores the growing unsustainability of the textile industry due to increasing textile waste and the reasons behind this, such as growing consumption and poor disposal habits. We chose NUS students as our target group because NUS students fit the profile of the largest consumer group (young adults) and hence contribute the most towards clothes wastage. Also, the reason why we’re holding this in NUS is because many students participate in existing initiatives like the Green Wardrobe and Green Bazaar. A preliminary survey on 230 NUS students during the Chinese New Year break concluded that our solution to target disposal habits should include monetary incentives and promote convenience in order to be effective. Hence, our proposed solution to reduce textile wastage is to bring the concept of thrift shops to NUS, which involves a combination of convenience and incentive to recycle. We hope that through this experience, more young adults will be more open purchasing used clothing and hence lessening the environmental impact of textile waste.

While the importance of recycling has been instilled into the public’s psyche due to government efforts to increase recycling rates, incorrect categorisation of rubbish and recycled waste contamination still remains a pressing issue. Some possible reasons for the abovementioned problems include the failure to recognise labels on receptacles or limited cognitive processing as people multitasked and thus disposed their recyclables into the wrong recycling bins. Overtime, this may result in an increasingly polluted recycling stream and a costly downstream recycling process. This project aims to encourage correct disposal and recycling habits, which in turn reduces the rate of contaminated recyclable waste. We will conduct survey to identify the preferred mode of instructions on recycling lids that would help correct disposal habits. We target all three types of recycling bins available in RVRC – Metals, Plastics and Paper. Our survey would also test the awareness level that used food containers and plastic bottles need to be washed before disposal. To increase the salience of the bin, recycling compliance as well as the accuracy of items recycled, we will replace the lids of recycling bins with specialised lids that reflect the shape of the item meant to be thrown. For example, a bin meant for plastic bottles will have the outline of a plastic bottle on the lid. This way, consumers will be able to identify these bins from a distance, even if they were multi-tasking. Furthermore, recycling bins will also be fitted with pictorial instructions to facilitate correct recycling methods. Although recycling bins have become an omnipresent part of our lives, the right recycling habits and accuracy of items disposed play a crucial role in ensuring that recycling rates increase in both quality and quantity.

Our project explores the feasibility of bicycle sharing in NUS as an alternative to the NUS shuttle buses, which are often crowded during school hours. Bicycle sharing has gained popularity in school, towns and cities around the world. As there is no such system in NUS yet, we would like to find out whether such a system, if implemented in the local context, would be effective. We define effectiveness as the percentage of participants that display positive feedback towards the bicycle-sharing system. We will look at how frequently they use the system and more importantly, find out if the participants are willing to continue using it alongside buses. We will also look at the issues they encountered and hopefully use their responses to improve the system. Using quantitative data provided by MoBikes’ existing system, we will also assess user patterns and draw conclusions on whether the system is an effective alternative transport system to buses. A volunteer group of participants will take part in a 2-week pilot test. Participants will be given promotional codes for the MoBikes App so that they can use the MoBikes system for free. Four MoBikes docking stations will be installed in NUS during our pilot test and the participants will be required to use designated cycling routes. We will conduct a pre-test survey to gather data on the participants’ current main transport patterns. After the test, we will conduct a post-test survey to find out if they felt that the Bicycle Sharing system was a viable form of transport that could rival the shuttle buses.

Academic Advisor: Dr. Chua Siew Chin

In Singapore, the use of electrical dryers for drying clothes is a waste of energy considering the hot local climate. Our preliminary survey showed that many residents of Ridge View Residential College use electric dryers for drying clothes. This could in part be due to the lack of adequate communal areas for the residents to dry their laundry. Our idea revolves around the substitution of electrical dryers with the conventional clotheslines. This solution provides a practical way to dry clothes indoors as it is space efficient as compared to regular clothing racks. Being retractable, the clothesline will not obstruct the residents. The clothesline will also save $1 per dryer use for students. We also want to find out whether the availability of clothesline could cause a change in students’ mindset with regards to the use of dryers. We will be conducting a pilot test with tension rods in place of a retractable line to assess the feasibility of our idea for a college-wide adoption. In short, through our project, we aim to uncover new insights on dryer usage habits and to reduce the reliance on dryers.

Academic Advisor: Ms. Sadaf Ansari

Energy consumption, while vital to our modern day living, is a source of many environmental problems such as the burning of fossil fuels, which in turn produces vast amounts of carbon dioxide that contributes to climate change. Statistics indicate that several developed countries face the problem of unsustainable energy consumption, but the cause remains unclear in spite of ample publicity, education and established measures to curb energy waste. At an individual consumer level, it is posited that the crux of this issue lies in behavioural psychology, particularly in the field of habit formation. Our project aims to identify the key reasons behind unsustainable electrical consumption behaviour at Ridge View Residential College (RVRC). We will be conducting this through a randomly selected pool of respondents. The first step in the project is to survey the sample resident population on their current electrical use and their justification for their habits. The second step is to study their daily usage habits in-depth, in the form of logbooks to better pinpoint the exact challenges participants face in practicing responsible energy usage and mitigate inaccuracy of answers in the survey stage of the experiment. Finally, from the data collected, solutions fitting the current dynamics of the target population to combat irresponsible energy usage can then be crafted with greater effectiveness.

GEQ Group 27 AY2015/16 identified an interesting point regarding the role of convenience in promoting recycling habits in their project. As an extension of their idea, we seek to investigate if the converse would be true: would increasing the difficulty of disposing unsorted general waste encourage the act of recycling? Thus, our team is investigating the correlation between recycling and convenience during specific time windows. Additionally, we are looking into contamination rates of the recycling bins before and after our investigation. We will be carrying out our pilot study at one of the Blocks at Ridge View Residential College (RVRC) to check if raising awareness can contribute to a reduction in contamination and an increase in recycling rates. Keeping in line with RVRC’s vision of sustainability, our goal is to cultivate better recycling habits among residents. These habits, and the methods used to cultivate them, possess the potential to be scaled up in the future to include the rest of Singapore, fostering a positive culture of being proactive when it comes to recycling. In a nutshell, we feel that there is room for improvement when it comes to recycling. Rethinking and recalibrating the current methods in place, we intend to begin by centralising general unsorted waste disposal and revising existing recycling practices if required.

Academic Advisor: Ms. Sadaf Ansari

According to a National Environment Agency study conducted in 2015, Singapore had 785,500 tonnes of food waste with only 13% of the food waste being recycled. That implies that on average, Singaporeans are wasting 140kg of food annually. To compound the issue, Singapore’s food waste has increased by 47.8% in a decade. As a small nation, reliant on imported food, a staggering 13% of its food imports ends up as waste, creating an unsustainable scenario with grave environmental implications. For processed food, a large percentage of this food waste may often result from confusing food labels that are not correctly understood or interpreted by consumers. Our project decided to explore this problem in the context of residents at the Ridge View Residential College (RVRC). A large fraction of residents purchase and store foods incorrectly in their rooms or the common pantries. This often results in food waste, evident from the numerous management-conducted food clearing exercise done in the common pantries. Our group has identified the following two points as key reasons to why this issue is happening: (1) Lack of awareness and implications of the different type of food labels, and (2) Lack of awareness of the proper storage methods of different food types. Our study will conduct surveys to measure the current awareness of RVRC residents on both these factors. We will concurrently be carrying out a college wide campaign to raise awareness about food labels and food waste through posters and social media platforms. We will document our findings and explore if increasing awareness about food labels could be an effective solution to mitigate food waste.

Palm oil is pervasive in our daily lives: from the food we consume to the toiletries we use for personal hygiene. As palm oil can be used for various purposes, the demand for palm oil will definitely increase. A report by United Nations Environment Programme acknowledges that oil palm plantations are now the main reason for rainforest destruction in Malaysia and Indonesia. In 2013, Singapore experienced the worst haze outbreak as the Pollutant Standard Index (PSI) hit 400 due to smog blown over from forest fires in Indonesia. Since then, people are more concerned about haze. Purchasing a product that contains palm oil will be akin to supporting companies which allow uncontrolled deforestation. Our group would like to raise awareness among NUS students about this pressing haze issue. This is done through engaging dialogue sessions, workshops and educational visuals. With these, we hope that more will buy products with Roundtable on Sustainable Palm Oil (RSPO) label or products that do not contain any palm oil.

Social media usage has increased significantly around the world, with Singapore expecting to have around 3.2 million Facebook users by 2018. Such usage involves data centres which require a large amount of energy to function. Facebook data centres were responsible for emitting 649,000 tonnes of carbon dioxide in 2016. We hope to encourage users to reduce their social media usage, in particular Facebook, by exploring alternative ways to engage their time. Our execution consist of two phases. The first phase is to increase awareness of the impacts of data centres and social media usage. This is done through visual posters displayed in RVRC and also oral presentation in social gatherings. Volunteers joining our programme then take a pledge to reduce their social media usage. For the second phase, we will organise different activities, such as movie screenings or a board games session, and get participants to join us. Throughout the project, we will monitor the participants Facebook usage through a tracking application called My Data Manager. We hope that this programme will initiate a behavioural change and reduce usage of social media for our participants.

Academic Advisor: Dr. Chua Siew Chin

Recycling of plastic bags is largely inefficient and tedious, as both the production and recycling processes consume energy. Moreover, in Singapore, only 7% of plastic bags are actually recycled due to the poor recycling culture. A more direct intervention is to stem the use of plastic bags. To promote less plastic bags usage among students, our group proposes “No Plastic Bag, OK?”, a project in collaboration with the Subway branch at Yusof Ishak House (YIH). Food outlets at YIH are just a short walk away from Ridge View Residential College (RVRC) and are frequently patronised by RVRC residents. Yet, we have observed frequent usage of plastic bags by residents whenever they take away their meals, which is a wasteful practice, especially for such short trips. This unnecessary consumption of plastic bags results in high levels of plastic waste. Our group will primarily use pre- and post-implementation surveys to gauge the receptiveness of our project. We will also use collect data during implementation to determine the success of our project. In summary, we aim to decrease the plastic bag usage of patrons at Subway and to encourage the conscious choice of declining plastic bags.

NUS provides internal shuttle buses as the main mode of transportation for commuters within the campus. However, these buses become severely overcrowded particularly during peak hours. This issue will continue to exacerbate with increasing student recruitment. Should frequency of bus services increases to match the demand, the cost on man-hours, fuel consumption, labour, and other resources would be environmentally and economically unsustainable. To tackle the prevalent issue, we plan to implement a mobile application to encourage people to walk instead of taking the shuttle bus service. We also plan to create an algorithm that would allow students to plan their timetable on NUSmods such that their travel distance between classes is minimized. This would incentivize them to walk to their next class instead of taking the shuttle bus. To study what motivates commuters to walk, we plan to survey NUS students to find out the factors of consideration for their transport options. Our mobile application will then concentrate on such motivations to incentivise people to walk. In a nutshell, our research areas will involve three fields:

  1. What motivates people to adopt the different modes of transport?
  2.  Case studies of societies where the walking culture is prevalent.
  3. Study of existing/proposed ideas to encourage people to walk and why some of them failed.

Today two-thirds of Singapore’s land areas serve as water catchment areas, meaning that much of our urban surface water runoff ultimately is captured and recycled for our usage. Bioswales are green landscapes that could improve the quality of the surface water runoff, as they are designed to reduce the amounts of toxic pollutants in storm water. Bioswales are increasingly popular in recent years as part of Singapore’s green landscapes but not many people know about them, their purposes, nor their effectiveness. Our group aim to test the effectiveness of bioswales in cleansing the storm water. We will mainly be testing for pH as well as the presence of heavy metals like Lead, Aluminium and Copper, as a measure of water quality. Since testing the water collected after having gone through an actual bioswale is unfeasible due to safety precautions, our group is modelling 3 miniature bioswales to carry out the experiment. By planting rosemary, basil and mint respectively in a layering of gravel and different types of soil, we will be filtering storm water through these bioswales and testing the water quality before and after the process to check for improvement.

Academic Advisor: Ms. Sadaf Ansari

Water shortage is a crucial issue that is slowly becoming a global crisis. While Singapore currently enjoys water security, as our demand for water grows in tandem with economic growth and population, we need to be able to secure a sufficient supply for future generations. Moreover, studies indicate that people Singapore residents typically do not feel a financial pinch when it comes to excessive use and wastage of water, especially during showers. This is primarily because users do not know the quantifiable amount of water they use per day. We hope to address this awareness issue with the use of an interactive device that prompts ‘Seeing is believing’ and prompts action. Visual display devices cataloguing and indicating use have been proven to be effective in reducing water and energy usage in Australia. TAP for Water is a project to reduce water waste by Ridge View Residential College (RVRC) residents by targeting shower times as it is one of the activities that causes the highest volume of waste water. In addition to the visual display to increase user awareness, our idea also incorporates a tariff system where RVRC residents need to tap their matric card/concession card (with ID registration) to activate water-flow for shower. Our aim is to target and modify daily habits involving water waste through awareness of consumption patterns, that could be potentially charged to the user. We will conduct 3 separate tests:(1) Pre-Project Survey, to estimate the average showering time for both genders, (2) Pilot-Test Stage 1, to test the hypothesis that students will reduce their shower times if the actual duration of the shower and quantity of water used is is made known to them, and (3) Pilot-Test Stage 2, to test the visual display & tariff device and troubleshoot any technical issues when using the device. Based on a successful pilot of all three stages, we will make our recommendations to the Office of Housing Services at RVRC for adoption.

Our group aims to investigate if an increase in awareness about environmental impact of consumer habits could lead to a positive change in sustainable behaviour. As residents of Ridge View Residential College, our meal plan includes food options from Sarpinos. During the course of our stay, we have noticed a particular wasteful consumer trend at Sarpinos (YIH branch) – consumers prefer to order food in take-away corrugated cardboard boxes instead of paper plates, even when they consume the food in the covered spaces around the outlet. Our research shows that corrugated cardboard boxes have a much larger carbon footprint as compared to paper plates. This prompted us to tackle this problem of food packaging wastage for our project. We intend to conduct our fieldwork and encourage patrons to make the switch to paper plates in a 3-stage process. In the first stage, we will observe and tally the typical number of consumers who do opt for paper plates. In the second stage, we will display a poster prominently at the front of the store to motivate people to choose ordering on paper plates over cardboard boxes. In the final stage, we will request the Sarpino employees to assist by asking customers if they really need a box. We will monitor and document the trend over this 3 week period to find if there would be an increase in the uptake for paper plates due to the increase of awareness.

The current, unfavorable method of disposing food waste is incineration at landfills. This results in severe environmental impacts, such as the emission of greenhouse gases, which in turn contribute to global warming. Such impacts can be reduced by recycling food waste. However, in order to recycle food waste efficiently, it has to be separated from general waste such as tissues or disposable cutlery. Our project will investigate this idea by piloting waste segregation at common pantries in Ridge View Residential College (RVRC). Over a period of 2 weeks, we will document the success of waste segregation by placing bins for the separation of food waste and general waste. We will begin this effort with an awareness campaign at RVRC using posters to inform residents in the first week. In the second week, we will remove the posters to observe if residents continue to separate food waste without being reminded. On the whole, our project aims to see if we can cultivate a culture of segregating food waste in RVRC.

Food wastage where produce is rejected based on appearance is a significant problem. In Singapore, 300 tonnes of unsold food were discarded each month. The goal of this project is to encourage consumers to purchase aesthetically displeasing (or ugly) food, specifically oranges. This is done through short slogans displayed on posters. The posters will be placed directly above the baskets in which oranges are stocked in the NTUC Xpress at University Town on the NUS campus. We will attempt to quantify this change in attitudes by conducting surveys to compare orange selection habits before and after displaying the posters. We will also conduct on-site observations to see first-hand the effect of the posters on consumers. At the end of our project, we would like to observe positive changes in consumer’s attitude towards ugly oranges. Our long term belief is that these positive changes in consumer’s attitudes can go beyond our scope and be translated to general fruit selections and consumers islandwide.

Showering forms a significant amount of monthly domestic water consumption in Singapore households. Studies also show that reducing shower time by one minute can lead to significant savings in water usage. Our group aims to examine whether the time taken to shower can be reduced by installing shower timers in the shower cubicles used by the residents in RVRC. The shower timers consist of 5-minute hourglasses which are attached onto the walls of the shower cubicles on level 3 and 4 of RVRC Tower Block. Data on the usage of shower timer and showering time was collected over a period of 4 weeks using door-to-door surveys. Secondary data based on the water meter measurement of RVRC Tower Block in February and March 2016 and 2017 was collected to compare the difference in water consumption and assess whether the installation of the shower timer has led to a decrease in water usage. The project hopes that installing visual reminders has a positive impact on reducing water usage during showers.

Singapore is a highly urbanized country with very little land available for food production. Over 90% of our food is imported. Food security is a key concern in the light of climate change where our food supply might be disrupted. Urban farming, where edible plants are grown in buildings, has the potential to supplement an individual’s diet. Growing your own food also reduces the carbon footprint incurred in buying imported produce. Focussing on undergraduates living in residential colleges, our group engaged the RVRC community by issuing a Plant-It-Yourself kit, to be grown over the course of 5 weeks. This kit consists of seeds potted in recycled containers and a digital instruction manual. The two main criteria for success to gauge their change in mindsets are: (1) the level of interest of participants has increased, (2) they expressed interest in the continuation of growing their own food. We will gauge these through surveys which will be done at the start, middle and end of the project to evaluate whether there is a progressive change in mindset. We propose that opening mindsets of students can be the first step in making growing their own food a sustainable lifestyle.

Academic Advisor: Dr. Chua Siew Chin

With growing affluence, food waste is increasingly an issue in Singapore. Food waste can be classified into post-consumed and pre-consumed. Our group choose to tackle the issue at the pre-consumed food stage, because this will ultimately reduce the post-consumed waste. Based on our observations at various canteens and from previous group’s results, we realise that rice is the most commonly wasted dish due to a mismatch between the portion of rice served and the individuals’ appetite level. This problem can be solved by better matching the individual’s need with the amount of rice served by the vendor. We intend to implement a rice level chart where customers can specify to vendors the rice quantity that they want, thereby reducing the level of food waste. Our inspiration comes from the sugar level chart implemented by Gong-Cha, where customers have the autonomy to decide the sugar level they want. Our target stall is the mixed vegetable rice stall at Business/Computing canteen We intend work with the stall vendor to implement the more/less rice ordering system over a week, and thereafter, survey the students’ responses to verify the viability of our idea. We hope that our idea can encourage you to think twice about rice when you are eating out.

Due to its non-point source and trans-boundary nature, marine trash has been an unabating issue for Singapore’s coastlines despite many years of coastal cleanups. Their impacts on natural ecosystems such as mangroves go beyond mere unsightliness, to potentially damaging young mangrove saplings. Using Sungei Buloh Wetland Reserve (SBWR) as a case study, our project seeks to understand the flow of marine trash in Singapore. Specifically, we aim to trace the sources of marine debris found at the eastern mangrove coast of SBWR through the following:

  1. Take photos of the marine debris at the eastern mangrove coast.
  2. In a non-bias manner, collect all trash in a designated area and categorize them as “local”, “foreign” and “cannot be determined”

Our preliminary expedition suggests that a majority of the debris at SBWR belongs to Malaysia. Thus on top of more field work, we will also consider how distinct types of debris (e.g. glass bottles, food packaging) are carried to the eastern coast due to current movements (longshore drift, tide levels, monsoon wind direction).

Laundry detergent is an ubiquitous and indispensable household commodity. However, detergent use could cause serious environmental repercussions, as chemicals such as phosphates in detergents could end up in water bodies via the wastewater system. This could lead to eutrophication and harm aquatic life. Excessive use of detergent would thus exacerbate these detrimental effects, and yet our preliminary survey shows that among the student community, there is little consciousness of the appropriate use of detergent. With the aim of alleviating these harmful consequences of laundry detergent, our project strives to promote consumer awareness about these repercussions and encourage good laundry habits, through educating the RVRC community on appropriate detergent usage and dosage. Our project has two approaches. First, we will provide weighing scales and measuring cups in the laundry room for residents to weigh their laundry load and to measure the appropriate dosage. Charts will be put up to inform residents of the appropriate amount of detergent to use based on the weight of their load. Our second approach involves educating the RVRC community on the harmful effects of laundry detergent and provide tips to encourage a change of laundry habits. Also, we will promote the use of detergent with the Eco-green label. Educational posters will be put up around RVRC to raise awareness. Finally, the success of our approaches on survey will be based on survey responses from the RVRC community.

Our project ‘One Camp, One Tree’ addresses unnecessary paper wastage in the usage of hard copy indemnity forms. This is done by replacing the current hard copy forms with a secured online portal. By implementing this schoolwide, the project aims to save 30,000 sheets of paper. Hard copy indemnity forms serve to indemnify the institution from any injuries incurred by the participants during school activities. The online portal serves the same function and brings about additional benefits such as easier access and greater convenience for participants. Furthermore, it simplifies the data collection and collation process for the organisers. We have implemented a pilot test in Ridge View Residential College for the Coastal Cleanup event. The pilot test had a sample size of 120. After the pilot test, we collected qualitative data on the effectiveness and feasibility from the organising staff, as compared to previous sessions where the event was indemnified through the use of hard copy forms. It had garnered positive feedback from the organising team and they have adopted this procedure for subsequent RVRC events. We crafted a suitable administrative framework for organisations within NUS to adopt that would allow them to more easily use digital means for indemnity purposes instead of traditional hard copy. We then intend to promote the usage of this online platform in different faculties and residential colleges, and eventually implement it schoolwide.

In the past 50 years, a 24% increase of meat in the weight of food in the global diet has led to a 108% increase in biomass demand. The processing of livestock is considered more resource intensive (Bromberg, 2004) compared to meat analogues2 (Joshi and Kumar, 2015). Hence, the purpose of our research is to study the plausibility of introducing meat analogues into one’s diet to reduce meat consumption. Preliminary investigations through an online survey (125 respondents) reported that 98% eat meat as least once a day. Also, 61% were open to the idea of replacing actual meat with meat analogues. This was followed up with face to face interviews to affirm the authenticity of the online survey. The interviews paralleled the results obtained in the survey. Moreover, differing proportions of texturised soy protein, (20%, 40%), were tested through a blind taste test (42 respondents), in which its aim was to gauge the combination that replicated the satisfaction of real meat the most. The results showed that there was no significant difference between the taste of the food sample containing 20% of meat analogue and the control sample (100% real meat). A 20% replacement of meat with texturised soy protein, when extrapolated to the whole of NUS, would result in a reduction of approximately 25.5kg of CO2 per serving of meat consumed.4  In addition, above 88% of respondents accepted both 20%/40% of meat analogue in the samples given. With improved techniques of food processing, the possibility of a 40% replacement proportion might be more acceptable. These promising results create an avenue to (i) Conduct a taste test on a larger scale, and (ii) Collaborate with small F&B restaurants such as The Royals Bistro, to work out the feasibility of incorporating meat analogue into their menu.

In NUS, recycling bins are placed around the campus to promote recycling habits among students. However, based on two surveys conducted in Ridge View Residential College (RVRC), we found out that almost 70% of respondents rarely or never recycle. Among these respondents, the most commonly cited reason was inconvenience and laziness. As for residents who habitually recycle, the reason given by them was convenience. The contrast in response between the two groups has led us to investigate if proximity affects recycling rates. Currently, the recycling bins in the tower block are only placed at one end of each floor which makes it inconvenient for the residents whose living on the other end to do recycling routine. From the survey conducted, 82.4% of the sample residents in tower block had agreed that having closer recycling bins might motivate them to recycle more. Many studies include Folz’s experiment had also shown that residents are more willing to participate in recycling activities. Folz’s result had revealed that communities with curbside collection had higher participation rate than the communities with local drop-off, which is 45% compared to 25%. (Domina & Koch, 2002) Hence to find out the impact of distance between residents and recycling bins towards recycling rate, our group have reallocated the bins in tower block next to the lift lobby – a more central location – so that residents have equal accessibility to the bins.

Showering takes up about 29% of a household’s total water consumption, yet, a minute less in the shower can save nine litres of water. By changing one’s showering habits, significant amounts of water can be saved. Several initiatives by NUS that reduce water wastage include the use of water-efficient fittings and the installation of thimbles in taps. Events such as the InterHall Environmental Awards competitions were held to cultivate sustainable practices amongst hall residents. However, such efforts do not directly impact an individual’s water consumption habits. Our group aims to affect a change in individual shower time. Water meters that provides real time information to users have been utilized in households worldwide, whereby water consumption was reduced by up to 15%; as of 2014, people in England and Wales. We will be testing the effectiveness of water meters in a residential college setting by installing water meters in eight shower cubicles of RVRC. The dynamic feedback provided would decrease users’ showering time, therefore increasing water savings. Through this project, we hope to raise awareness of each individual’s water footprint in the shower and reduce their showering time over the long run.

Academic Advisor: Mr. Lim Cheng Puay

In a highly urbanized country with a 45-hour average work week like Singapore, coffee consumption is rapidly increasing. Coffee generates an average of 50 tonnes of grounds, which is incinerated together with other food waste. Besides the issue of the limited capacity of Pulau Semakau for waste disposal, wet coffee grounds present problems with waste incineration, as its incineration requires more energy. Our group aims to alleviate the problem by re-purposing coffee grounds for other uses. Through this, we aim to not just help to alleviate coffee’s polluting effect, but also create an alternative material for practical usages in daily life. By combining coffee grounds with materials such as beeswax, resin and we intend to create a material block that does not easily turn moldy, has certain tensile, strength, impact absorbent and hardness properties. To test for these desired properties, we intend to use equipment found in the engineering laboratories to obtain reliable tests and data through which we can evaluate our material. To further substantiate our material, we intend to use the same evaluation for other materials and compare that with our material to show that our material is feasible for adaptation into products.

Academic Advisor: Mr. Lim Cheng Puay

One source of plastic waste from students living in residential colleges will be that of plastic soap bottles. Of the 110 RVRC residents surveyed in our study, the average resident used 1.46 soap bottles in a semester. In RVRC alone, this means that its 650 residents produce approximately 85.4kg of plastic waste in a year. This presents a significant source of plastic waste which is present in all student residential areas in NUS. As such, our team is interested in exploring implementation of shared soap bottles within RVRC so as to minimize plastic waste generated. Ultimately, our study aims to reduce the residents’ usage of their own soap by 20%, from 1.46 bottles per semester to 1.17 bottles per semester. Our project is carried out in three phases. First, we collected crucial background information about the soap consumption habits in RVRC and the environmental impact of plastic waste. Data of these habits was obtained through an RVRC wide survey. Based on this data, we designed a pilot test for a shared soap system in RVRC, taking student preferences into consideration. Second, we will conduct the test for three weeks at E Block for one male and one female washroom. At the end of testing, we will gather data of soap usage and user response to predict the effectiveness of the soap sharing system if implemented throughout RVRC.

Academic Advisor: Dr. Chua Siew Chin

Food waste in Singapore has been steadily increasing. Food spoilage from excessive groceries contributes in part to the food waste problem. In RVRC, we observe that the communal refrigerators are often packed with expired food, leading to food wastage. Expired food remains in the refrigerator long past their expiry dates. The likely reasons for these expired food include owners forgetting about the products and their expiry dates, or being irresponsible in clearing the products. The excessive and spoiled food compromises the hygiene of the communal refrigerators and takes up shared space. We aim to create a system to change the wasteful behavior of the residents. Our goal is for fridge users to take more ownership of their purchased groceries. We proposed a reminder scheme for individuals to monitor their products and a food labeling system to instill responsibilities among users. We will conduct surveys to gather a general consensus about food waste and feedback on our proposed system from common fridge users. Subsequently, we will be monitoring selected fridges across RVRC to create an inventory and categorize expiring or expired food products. We hope to better understand the issue of food wastage and hence create a solution to unnecessary food wastage, starting from the fridges of RVRC.

Academic Advisor: Dr. Chua Siew Chin

Despite measures implemented by the National Recycling Programme for the past fifteen years, domestic recycling in Singapore has stagnated at low rates of about 20% from 2005 – 2015. Similarly, our group observed low recycling rates within various residences in NUS. In an effort to boost the recycling rates in NUS, we propose two methods to encourage people staying in NUS residences to recycle. The first method, inspired its success in other university campuses, involves better placements of recycling bins to enhance the convenience of recycling. The second involves the introduction of community incentives to encourage members to recycle. To demonstrate the feasibility of the second idea, we will assess its appeal among students, and prototype a program that could track students’ recycling rates. These two methods would be tested out in different phases at Raffles Hall and Ridge View Residential College. Conclusions on the effectiveness of the measures proposed would be drawn via a comparison of recycling rates in each location before and after the measures were implemented.

Academic Advisor: Dr. Chua Siew Chin

Our team aims to investigate the feasibility of establishing zero-waste supermarkets in Singapore. The zero-waste grocery store was pioneered by two Germany-based social entrepreneurs, and reduces food waste through allowing consumers to choose the exact quantity of food they want to purchase. It also eliminates the packaging stage of the food production process. Consumers are encouraged to bring their own containers and bags, and purchase food items based on the weight of the products. The Ministry of Environment and Water Resource reported that food and beverage packaging comprises one-sixth of all domestic waste in Singapore in 2016. Household recycling rates are also relatively low in comparison to other developed countries, and public education campaigns have been unsuccessful in engendering commitment to recycling. We hope that the zero-waste supermarket, geared at prevention of waste, rather than retroactive mitigation of the impacts of waste, will improve environmental protection in Singapore. In order to answer the question of whether or not zero-waste supermarkets are viable in the local context, consumer demand for such a shopping experience is an important concern of corporations considering the shift towards zero-waste. Hence we aim to focus on the consumer aspect by investigating consumer likelihood to patronize such supermarkets, should they be set up in Singapore. Our project comprises a survey of the local population on their current grocery-shopping habits, as well as their willingness to go “zero-waste”, and a detailed analysis of the survey results within the Singaporean cultural environment.

Public spaces provide the platform for social activities and are crucial for social interaction in a community. Our project aims to explore ways to maximize the utilization of public spaces in Ridge View Residential College (RVRC). Currently, public open spaces around Old Kent Ridge Blocks are largely underutilized. The few built facilities present, such as the BBQ Pit and the Amphitheater, are inadequate in attracting student use. We conducted a literature review to identify the factors influencing human interactions as well as possible features that could be adopted to construct attractive and socially conducive public spaces. Our project incorporates participatory design by the residents at RVRC as our methodological framework to accurately reflect the needs and preferences of the users while simultaneously instilling a greater sense of ownership for the communal spaces. The college population was first surveyed to identify the spaces of greatest interest and to gather information on factors influencing the use of public spaces. This will be followed by a focus group discussion to streamline data into concrete co-created designs and finalize implementation details for the construction of a feasible prototype. We will conclude our project with the submission of a set of recommendations to the RVRC Management for adoption consideration.

In the absence of air-conditioning in residents’ rooms, year-round high humidity in Singapore is the chief cause for Ridge View Residential College (RVRC) students experiencing discomfort. Our project will be focusing on a specific design solution to combat humidity and improve thermal comfort of residents in RVRC using environmentally friendly methods. We propose to design a cheap and low-maintenance DIY air-cooling device made of readily available recycled materials – cardboard and plastic bottles. These materials are ideal for a sustainable solution as as they are insufficiently recycled in Singapore. Our idea is inspired by the project ‘The Eco Cooler’™ that debuted in Bangladesh as the world’s first ‘zero-electricity™ air conditioner’. It eliminates the need for energy to run the cooling system, thus producing zero waste products. The mechanism adopts the Joule-Thomson Effect where a change in temperature occurs when air is forced through a narrow opening. For data collection, we conducted a trial in the high rise RVRC Tower and Old KR blocks for a week each, using our neighbour’s room as the control while testing it out in our own rooms. Results were analyzed when fans in both rooms were either operating or not operating concurrently to reduce confounders. After receiving feedback on our results from our Industry Advisor, we modified our design to tackle humidity instead and will be conducting further tests to measure and assess the impact of the device.

In 2016, households contributed about 15% of the total energy consumption in Singapore (Energy Marketing Authority, 2016), a marked increase from 9% in 2005 (Low Carbon Singapore, 2011). On the other hand, domestic potable water consumption has only decreased slightly from 49% of total potable water use in 2009 to 45% in 2015, in spite of local policies and campaigns to lower consumption. With these key statistics in mind, and in view of Singapore’s reliance on external sources of energy and power, our team decided to address this problem at the college level. The goal of this project is to reduce electricity and water usage in Ridge View Residential College (RVRC) through SustainaBoard -an electronic display which we will design to primarily feature real-time water and electricity consumption statistics of RVRC residents. We aim to use this device to test if raising awareness of the potential savings consumers can achieve can create the eventual inculcation of long-term sustainable habits. Based on the feedback and results from the pilot, SustainaBoard has the potential to be further improved to include more features. The scope of the project can also be expanded upon in the future through collaboration with the other residential colleges and halls to increase awareness of domestic consumption and to promote sustainable living on campus. Furthermore, this project can look into including the conservation of other non-renewable resources instead of water and electricity alone.

Clothes washing is an essential part of daily household chores. Our project aims to maximise water efficiency and reduce wastage in laundry practices. Studies have shown that consumers tend to underload wash cycles, suggesting that excessive amounts of water and electricity are used beyond the optimal number of cycles required. Given that each washing cycle in RVRC consumes 50.8L of water and 1.2kWh, the accumulative wastage over time and across the population is likely to be substantial. As past sharing economy models have been successful, adapting it into communal laundry system could create a more sustainable living environment. We propose laundry sharing as a method to improve the efficiency of each individual washing cycle. We will trial the laundry sharing initiative and the feasibility of a pay-it-forward culture within RVRC. Firstly, we will perform a pilot survey to collect data on the awareness of laundry water usage and interest on laundry sharing. Next, a trial run is conducted with survey results on preferences factored in. Water usage changes will then be analysed to determine the potential savings and possible limitations. Lastly, a post-trial survey will improve the feasibility of the project. This project contributes to improving water saving habits and alleviates water and energy consumption in the long run.

Day-lighting systems, which capture sun rays and reflect them into buildings, can complement existing lighting installations in buildings to reduce energy consumption. Our group will examine light pipes as such a day-lighting system to reduce electrical dependency, specifically on cheaper alternative materials compared to current commercial models. This will be achieved with qualitative analysis and research by consulting experts from the Building & Construction Authority and NUS. A quantitative study by creating an experimental prototype light tube system using a cheaper, reflective material, “Mylar” will be carried out. We will then compare various lighting systems (e.g., LED, ambient lighting, etc.) and evaluate of the efficiency of the alternative material proposed as well as consider possible sites of integration and implementation. We will also engage RVRC students about our product to understand end-user receptivity and response towards light pipes, and the feasibility of light pipes lined with the alternative material we have proposed. This is done through a visual engagement and recording their experience with the prototype we have constructed. Through these various approaches, we will determine the feasibility and potential of light pipes as a complement to existing lighting systems.

Printing of lecture notes and their eventual disposal is an environmental concern, as shown in a study done by University of Michigan, where they reported 1.5 million kilograms of paper waste was generated annually. NoteAbility is a student-driven initiative, where unwanted notes are collected from students, then re-distributed to their peers via an online platform. We hope to tap on the the potential of reusing unwanted notes, by passing them on from one cohort to another, instead of discarding after use. This platform will manage the balloting for the notes, and facilitate distribution. A pilot project will be conducted in RVRC, during which notes will first be collected from the students, then quality-checked, before eventual redistribution. Ultimately, this platform aims to reduce printing of new notes, by encouraging students to share their old ones. This brings about savings in resources required for paper production, printing, and paper waste management. We hope that this environmentally friendly practice of recycling lecture notes can be implemented at a larger scale after this project.

The academic curriculum at most faculties in NUS carries a high proportion of project work. This increases the likelihood of every student working on at least one, if not several projects during their studies. Project work not directly pegged to modules are also encouraged for student learning and experience, with NUS having a yearly Student Achievement Award that recognize these efforts. However, the conclusion of student projects at the end of an academic module or stipulated deadline tends to abruptly end work on them without prospects for continuation. This means that previously invested intellectual and financial resources are often wasted when the projected deadlines cause discontinuation of further development of student ideas. Titled ‘Project Match-Make‘, our team aims to bridge the pool of existing student-led projects with the students who would potentially want to work/continue on similar projects. This would ensure the long-term sustainability of such ideas and projects. Our project involves the development of a school-based platform that serves as a medium for students to publicize their ideas and recruit new talent, and to aid interested students in seeking out relevant existing project ideas in their field of interest. Our intended project audience is the NUS student body.

With expanding urban development, forests and agricultural land all across the globe are rapidly being replaced by buildings and skyscrapers. The density of urban development in cities with scarce land, such as Singapore, compounded by high rise buildings, leaves limited opportunity for greenery and landscape. This carries a wide range of negative environmental impacts, key among which is the Urban Heat Island (UHI) effect that changes the urban micro-climate with intense pockets of higher temperature and disturbs ecosystems in the immediate vicinity. The simplest method to combat this phenomenon is the reintroduction of plants and trees. Increasingly, this is being achieved in cities by the use of green walls, which are said to mitigate the UHI effect by decreasing ambient temperatures in the surroundings, while simultaneously improving biodiversity and user perception of urban spaces. Our project examines these attributed benefits of green walls as effective replacements of natural landscapes on the NUS campus, especially when considering their high installation and maintenance costs. We chose to test the efficacy of 5 different green walls at 4 locations around the NUS campus – VENTUS, FoE, SDE and Kent Vale Residences. We aim to assess the performance of these green walls with respect to their key projected benefits; reduction of ambient temperature around the walls, increased biodiversity on and around the wall, and positive human perception of the green walls as effective replacements of natural landscapes. We will be using a combination of fieldwork and surveys to collect our data for analysis.

Every year, about 65% of the global agricultural produce is lost or wasted. This is a severe issue as food production accounts for 65% of the global greenhouse gas emissions and requires extensive natural resources such as water and land. This waste is more prevalent in industrialized and medium-and-high income nations, such as Singapore. A key contributor to this waste is ‘Ugly Food’- raw produce that is rejected due to its poor visual appearance – like misshapen, discoloured or bruised fruits and vegetables. According to a survey done by Electrolux in 2015, about 83% of Singaporeans only purchase fruits and vegetables that look fresh and good, avoiding ugly food that remains largely unsold and is eventually disposed of. Their survey also showed that 75% of Singaporeans would consume ugly food if they considered it equally nutritious and delicious as other food. This shows a widespread consumer misconception about ugly food – assuming ugly food to be a source of contamination, of poor nutritional value, and a health and safety risk. Our project investigates the cause of these misconceptions in Singaporean consumers by conducting consumer surveys at NTUC FairPrice Xtra – a supermarket that sells ugly food. Our project also targets raising awareness by hosting an Ugly Food Day at Ridge View Residential College (NUS), that includes conducting a double blind test sampling of fruit juices of ‘ugly’ fruits vs normal fruits. The final aim of our project is to gather evidence to propose practical strategies to combat this problem, both on campus as well as beyond, by raising awareness and changing consumer mindsets.

Considering the many fruit juice stalls operated in cafeteria on the NUS campus, an abundance of fruit pulp is disposed of as waste daily. With large areas covered by landscape, significant leaf litter is also generated as waste. Composting can effectively bridge the life cycle of these easily bio-degradable wastes of fruit pulp and leaf litter by turning them into useful compost. Inspired by the setting up of the Edible Garden at Ridge View Residential College (RVRC), our project aims to explore the feasibility and pilot a a student-led sustainable composting system. We also aim to document our learning experiences in a booklet for sharing with other student groups on campus. Aligning with the goal of a student-led system, our project had three main considerations. Firstly, the composting period must not exceed the duration of a semester, since monitoring the set-up would be difficult during the long semester break. Secondly, the set-up should be easily implemented to allow subsequent student groups to take up and sustain the project. Thirdly, the system should run on little or no operating/maintenance cost, excluding initial setup cost, in order to be deemed truly sustainable. With these principal considerations, we chose to test bed the Berkeley Composting Method as the most suitable option that fulfills all three criteria; it has a short composting period of 3 weeks, requires a simple set-up procedure of 4 to 5 steps, and has no operational costs apart from initial capital. We conducted two separate staggered pilot tests, to rule out incidental variations and gauge the feasibility. We will be sharing recommendations for future attempts based on this.

Food waste is unsustainable and undesirable. Besides the meaningless squandering of natural resources, it causes significant and dire environmental impacts. Our team decided to continue a study done by Ridge View Residential College (RVRC) students in AY2015-16, which discovered that food caterers at NUS Residential College (RC) dining halls err on the side of caution and typically tend to over provide student meals to ensure that residents have sufficient food to eat with a wide variety of food choices. Our study found that this is further compounded by the caterer’s inability to correctly predict the number of students going for each meal, or the take-up rate for the different types of food. We found that these factors lead to a significant amount of cooked food being left unserved on a daily basis – often as much as 15%, as indicated by the caterer of the RC dining halls. RVRC will have its own dining hall in AY2017-18, and as future residents, our team focused on exploring a potential solution to reduce the amount of unserved cooked food, by allowing paying student diners to have ‘Self-served Seconds’ at each meal after the close of dining hours. In order to gauge operational challenges as well as student perception to our proposed solution, we pilot tested this idea during term time at the CAPT-RC4 Dining Hall. Our findings assess the success of this initiative by measuring the amount of servings wasted before and after the implementation of our pilot test. Our study also integrates this data with survey responses from student participants of the pilot test to give an overall measure of success of our idea and potential changes for future adoption at RVRC.

Our group conducted a survey on the energy consumption patterns in the student lounges at Ridge View Residential College (RVRC). The results, which polled 78 RVRC residents, showed that more than 75% of the respondents had observed lights, fans and air-conditioning left switched on when no one was using the shared spaces. Additionally, around 50% of the respondents admitted forgetting to switch off these appliances before leaving the lounge themselves. Using these results, our team demonstrated that the net electricity wastage could amount to as much as S$11000 every month. To verify our survey results and the resulting electricity waste estimation, we conducted further investigation with a two-week observational study on the student electricity consumption patterns in the Conference Room, Meeting Rooms 1 and 2 at resource@rv. This fieldwork was done anonymously and was targeted at frequent users of these shared spaces, i.e. residents who use these facilities more than once during the observation period. To follow up, these students were sent a personalized survey to investigate if their perception of their own consumption pattern was, in fact, consistent with their documented actions. These results were collectively analyzed to identify student electricity waste patterns in shared spaces, investigate possible reasons for lack of individual and collective responsibility and recommend effective improvements to the Office of Housing Services at RVRC for future implementation. Key among these recommendations is pilot testing of a matric card reader to activate electricity use, placing individual ownership of electricity consumption in shared spaces.

The use of plastic shopping bags is ubiquitous in Singapore’s consumer culture, with an estimated 3 billion bags used in 2011. Life-cycle analyses of plastic bags have demonstrated that their consumption exerts a heavy toll on the environment. Our literature review has validated the effectiveness of positive psychology (PP) in motivating behavioural change. We investigated if PP could be similarly applied in the composition of slogans to promote plastic bag reduction among RVRC residents. An online survey of 37 RVRC students was conducted where participants chose between slogans incorporating PP and without. The participants deemed slogans incorporating PP concepts to be more effective in encouraging plastic bag reduction. We also found that goal-based slogans were the most favoured across the PP concepts. Our results provide a glimpse into the psychology behind environmental slogans and may be used to help design future slogans and campaigns promoting plastic bag reduction.

As part of our efforts to reduce the environmental impacts of meat consumption, as well as the economic issues that is related to it, our group has researched extensively on the underlying reasons that discourages people from reducing their meat intake. We will be examining the impact of meat production and consumption, as well as the pattern of meat consumption among students from NUS (National University of Singapore) that has been collected through primary research. We have also collated interview data from the veterans in the Vegetarian Society Singapore. Using both sources of data, as well as secondary data sources, we formed hypotheses regarding the mindset of students in reducing meat intake. Following which, we conducted a focus group social experiment where we gathered the feedback of participants towards the alternatives of meat, such as plant-based protein sources, and also provided suggestions to help others reduce their meat intake.

Excessive food packaging practices generate large amounts of waste, with plastic packaging being detrimental to the environment and paper packaging not being entirely sustainable either. This project seeks to investigate the effectiveness of introducing alternatives and providing reminders to consumers towards achieving a reduction in food packaging usage. Lunch boxes were provided for a period of two weeks to a sample group of 20 students who were later surveyed for its usefulness. A Subway outlet in NUS was also contacted about putting up posters to raise awareness and dissuade customers from taking plastic bags. Results from introducing alternatives to consumers have been encouraging, while results from the engagement with Subway are pending. Should results be positive, the project could be implemented on a larger scale, and potentially help NUS take a step towards becoming a more sustainable community.

In this project, we will be exploring the possibility of achieving a paperless society in Singapore through reducing our reliance on paper. Contrary to popular belief, recycling paper is not sustainable as it is rather costly and environmentally degrading. Our project will be focusing on reducing print paper usage within the scope of NUS. This has been done through three phases: conducting a survey on 100 NUS students, interviewing staff in NUS printing shops and organising a social experiment on 15 NUS students. This will help us investigate in depth on the print paper usage of students, the aggregate amount of print paper used by the NUS community as well as the challenges students face in reducing their paper usage. The results of this project could lead to identifying possible solutions to reduce paper usage, which is the next step forward towards a paperless Singapore and a sustainable environment.

The importance of transport in today’s society cannot be undermined: it supports a country’s social and economic well-being. Unfortunately, the focus of transport policies on meeting utilitarian needs such as accessibility and travel time has resulted in other issues, such as air pollution and inefficient use of resources, being neglected. Hence the focus of our project: How to encourage the NUS community to adopt more sustainable means of mobility? After consolidating information from interviews with OES and OCA, our project decided to focus on walkability in particular: it was an area we could explore by ourselves. As many respondents to our survey indicated that knowing shortcuts would motivate them to walk more often, our group chose to disseminate such information. In closing, while it may only be a few routes at present, others can add to our work, and hopefully use it to encourage the walkability of the NUS campus.

40% of the water needed in Singapore is imported from Malaysia. With Linggiu Reservoir dropping to historic low levels, water sustainability is a major concern for our country. In NUS, RVR (Ridge View Residences) is one of the areas with highest WEI (Water Efficiency Index). Our project focuses on reducing water consumption in RVRC by changing behaviour and habits of students through an app that facilitates laundry sharing and reporting of problems for residents. Through surveys and research, we established the existence of the ineffectiveness of the report system and water usage doing laundry. By pitching our ideas to Living Lab, OFM and RVRC community, we came up with a design of the app and functions with cost benefits analysis to all shareholders. With the design aimed to promote usage of the app that will reduce water consumption, we are confident that it will be adopted in the future and allow us a step closer to achieving water sustainability.

The cost of food has been increasing annually and food wastage translates to higher costs for food suppliers and consumers. This project focuses on the causes of food wastage in dining halls, using the dining hall shared by the CAPT and RC4 in NUS as a case study. Qualitatively, the dining hall manager, caterers and students were interviewed to find out how the dining hall operates, the source of food wastage and difficulties in decreasing food wastage. Quantitatively, food wastage for dinner services were tabulated over a period of a week and compared to existing projections from the caterer. The results indicate that there are large fluctuations in take up rates for the various stalls and there is a difficulty in projecting the take up rates for each stall. Hence, a system to project the number of diners is key to alleviate this problem of food waste in dining halls.

A close inspection of the life-cycle-analysis of coffee shows that it is more that just a simple beverage. Coffee waste, in particular disposable cups, occupy substantial space in landfills and contribute to greenhouse gas emissions. Hence, our group advocates the use of reusable tumblers to reduce this waste. Our journey takes us through the lens of both managers and consumers to investigate the reasons for the poor usage rate of reusable tumblers despite monetary incentives. We surveyed 113 NUS students on their consumers’ coffee consumption habits and tumbler usage. Simultaneously, we conducted an interview with a manager of Starbucks in NUS to understand the challenges cafe owners face in implementing green initiatives. Through our research, we concluded that on the consumer side, convenience is the main reason hindering reusable tumbler usage and proposed several solutions. On the management side, a stronger willpower and a more proactive top-down approach is required.

We commenced our project by wanting to alleviate the food waste problem in Singapore. Singaporeans waste the equivalent of two rice bowls of food every day in a world where 1 in 9 people suffer from hunger. As such, our group aims to find out if popularising ordering options and monetary incentive would help to reduce rice wastage in our NUS canteen. We conducted multiple surveys and ground research to gather qualitative and quantitative results. In Semester 1, we found out that monetary incentive would encourage people to order less rice. (We assumed that when people to order less rice, less rice wastage would be incurred.) This semester, we pasted posters to raise awareness about food waste and the discount for the less rice option. Our study revealed an 18% increase in people ordering less rice largely due to an increase in awareness, which shows the viability of our hypothesis.

$200,000. That is how much NUS is wasting per year on lighting in common spaces. In this project, we explored how NUS could save electricity by investigating the effect of providing feedback on electricity consumption to residents. 3 posters with different design approaches were presented to 50 residents over a period of 2 weeks (13 – 26 March 2016), and investigated with a survey to determine their effectiveness. The results indicate eye-catching posters with real-time statistics on electrical usage are most effective. In conclusion, the way energy feedback is communicated can significantly impact the receptiveness of the recipients in prompting energy-saving behaviour.

Plastics are primarily produced from petrochemicals derived from oil and gas, and recycling plastics would help reduce the strain on Earth’s natural resources. Recycling can also be seen as a waste management strategy, reducing the strain on our landfills and prevents possible contamination of soils and water bodies. In 2014, the rate of recycling plastics in Singapore stands at 9%. Starting in RVRC, by increasing the number of recycling bins, we will make it more convenient for people to recycle by taking the bins to them and at the same time, start to cultivate the habit of recycling plastic bottles.

While technology usage is pervasive and obsolescence increasing, e-waste recycling amongst NUS students is less widespread. 75% of students do not recycle despite NUS’ recycling initiatives and the environmental and health threats loom ever more. Our project aims to find out how we can encourage more students to recycle e-waste. A literature review to understand determinants of recycling behaviour was followed by a survey of 154 students to gauge awareness and participation in recycling efforts. Based on this, informational flyers were distributed and a Facebook page about e-waste was launched. Our findings shows that 73% of students are willing to recycle if they know the consequences of improper recycling. For those who are aware, inconvenient access is a major inhibitor. We conclude that the university’s e-waste recycling will likely increase if NUS’ initiatives are augmented by awareness campaigns and improving access to recycling facilities.

With more than 90% of Singapore’s food needs being supplemented by exports, it is an undoubtable fact that self-sustainability is a big problem for our country and its food security. Limited land contributes greatly to our inability to manufacture our own food due to the spatial and ecological requirements of farming. The purpose of this project is to investigate the intricacies behind Singapore’s disability and methods by which we can alleviate the situation. In particular, we seek to examine the feasibilities of vegetarian alternatives to meat as a means to reduce the spatial and ecological impacts of meat farming. We are also aware of the entrenched consumer preference for food and have thus, decided on ways we can do to make the food more appealing to costumers. We hope that by doing so, we can take a small leap of faith in changing the consumer food preference in Singapore.

In 2015, the NUS Office of Campus Amenities recorded that it transports an average of 50,000 people around campus per day. Even with this efficiency, buses are overflowing with students. While increasing the number of bus trips seems to be a straight-forward solution, it might only worsen the problem due to the narrow roads and heavy traffic on campus. It also further contributes to NUS’s carbon emissions. With this in mind, we searched for a more sustainable transport alternative and collected the feedback on the willingness of NUS students and staff to walk as a mode of transport. Discovering that many are willing to go the distance if real-time information and a mix of modes of transport are offered, we focused on building a mobile application that will help NUS students to navigate their way around the campus, through the best permutation required by the student on each unique scenario.

Food waste makes up the second largest proportion of waste generated, at 22.5%, of which less than 15% is being recycled (NEA, 2015). Moreover, the amount of food waste generated has increased significantly over the past decade (NEA, 2015), and will continue to increase with greater wealth and an increasing population. As such, this project serves to look at ways to tackle food waste, in particular, food waste generated in the dining halls of the Residential Colleges in University Town. Food there is prepared beforehand and cooked in excess to cope with the possibility of a greater than usual demand. Food waste is thus a common sight, contributing to the waste generated in Singapore. This project explores the feasibility of bokashi composting and the use of a mobile application to both educate students about waste management and to help alleviate food waste in a sustainable manner.

The University years are a crucial habit-forming phase for students since it is the first time they stay away from a home setting and make their own food choices. Our group seeks to find out whether university students are eating healthily as they constitute the future workforce and are important in sustaining the nation’s development. We investigated the various factors that influenced their dietary habits to devise effective solutions. Of the 112 responses we received from 150 students across different disciplines, 94.3% are aware of healthy eating but there are still 44% skipping breakfast everyday and 12.7% eat fast food several times a week due to a preference for its convenience. Most importantly, 76.4% are unaware of any ongoing healthy eating campaigns in NUS. These findings imply the need to increase awareness and the availability of healthy food options, with incentives to promote healthy eating among university students.

Proper management of human-wildlife interactions is vital for sustainable development. This is especially true in Singapore, a small country with limited land space. The most well-known cases of negative human-wildlife interaction in Singapore are human-macaque altercations. Residents around nature reserves experience occasional home invasions by Long-Tailed Macaques (Macaca fascicularis) seeking food. Agencies such as ACRES and NParks responded with various outreach efforts, while AVA engages in culling. Culling in particular is an unfeasible and unsustainable long-term solution as macaques are important seed dispersers. The other measures, such as public awareness campaigns and monkey-proof bin installations are a much more sustainable means of addressing this issue. However, the effectiveness of these efforts has not been fully evaluated. In this project, we studied three of these measures and reviewed each of them. From our findings, we identified several issues present in these current implementations and proposed various methods to improve these efforts.

Singaporeans are huge consumers of technology where majority of the people desire and own the latest gadgets. Hence, devices quickly become obsolete and more e waste will be generated. The objective is to prolong the lifespan of these electronic gadgets as opposed to recycling them. A survey was conducted within Ridge View Residential College and the results indicate the lack of awareness and available channels to reuse their electronic devices. There is a common consensus to resell their items if a third party can help facilitate the process. Our solution: a mobile app. “Karang Guni” provides a convenient way to bridge sellers, 2nd hand dealers and recyclers together. All the sellers need to do is to enter their contact details and condition of their gadget. This quick and simple method enables potential pickup services to collect the items from them. Hence, we hope to increase the initiatives for reusing and recycling.

Food wastage is a serious problem in society that needs to be solved as it negatively affects society economically, environmentally and socially. Our project focuses on reducing food wastage through food catering events in Singapore. From our research, in NUS alone, 70% of catered food are being wasted on a regular basis and it is contributing greatly to the problem of food wastage. Foodjio is a mobile application that we have developed to help alleviate this problem. It works by collaborating with the organizer of food catering events to notify nearby users to travel down to help finish the catered food so as to reduce the occurrence of its wastage. Thus far, we have successfully developed the mobile application and it is undergoing testing on NUS users while undergoing a collaboration with ZeroWaste Singapore to plan to bring this application forward to the society at large in the future after successfully testing its practicality and usefulness.

Clothing wastage is a rising issue in Singapore. This is due to the fast changing fashion trends and low prices of clothes, which makes them easily obtainable. With more clothes being purchased, it leads to a domino effect of more being disposed. According to Technical Textile Markets, the rise in production in the fashion industry, has nearly doubled the demand for man-made fibers, especially polyester, in the last 15 years (citation). To add on, the recycling rate of textiles is very low at 11% (citation). Often, people are oblivious to such wastage.  Thus, we have decided to step in to increase the awareness of such wastage, in hope to reduce them. Our target audiences are the undergraduates and fresh graduates of National University of Singapore (NUS). To solve this problem, we came out with a two-pronged approach. The first being promoting the reduction of buying new clothes. The second would be to encourage the students to recycle the old clothes.  The success of our project would be evaluated based on increasing the number of recycled clothes.

It is important to conserve water is a resource-scarce country like Singapore. Statistics show that showering consumes one of the largest volumes of water daily. We investigated the effectiveness of campaigning in changing personal beliefs and attitudes of RVRC students by measuring shower volume consumption pre and post-campaign. A datalogger was installed in one toilet to record the amount of water used for showering. Posters with water conservation messages were put up, email and whatsapp reminders sent out to remind residents to reduce shower water consumption. Data concerning the amount of water consumed was also put up. Then, we collated data pre and post-campaign. Post-campaign results were encouraging as the volume of water used in showers have decreased steadily (1582.6L/day in week 1 to 372L/day in week 2).  However, during our campaign week, results were affected due to the installation of water pressure reducing devices by PUB. In conclusion, campaigning is indeed effective in reducing shower volumes in the long run.

Annually, more than 70,000 tons of waste glass is produced from the construction industry. Singapore either exports waste glass or dispose them into landfills given the absence of glass recycling plants locally. In this project, we investigated the steps required to adopt a closed loop system for glass use in the construction industry through recycling. A lack of policies to govern glass recycling and proper waste management at demolition sites has led to inadequacy in the efficiency of resource use for glass.  We investigated the status quo of glass usage and glass recycling in the construction industry. Studying the technologies and waste management techniques adopted abroad, we analysed its feasibility in Singapore’s context. It has been proven that usage of recycling glass in production of new glass reduces carbon emissions and contributes to greater product sustainability. Building codes governing practices of the construction industry can help create this closed loop system for glass in construction use.

Due to Singapore’s tropical climate, heavy rainfalls occur frequently resulting in flash floods. The implementation of Bioswales would slow down surface runoff to the drainage systems, hence reducing flash floods. Bioswales are suitable for NUS due to its undulating contour. They also contribute to the campus’ green space through functional and aesthetic means considering the campus’ proximity to Kent Ridge and Bukit Timah nature reserves. We aim to produce guidelines for building Bioswales with details such as the structural design, composition of the soil and the types of plants used. We also propose a retention tank to utilize the stored water for irrigation.  Our guidelines will be based on the studies of existing Bioswales in NUS. We would also identify other potential locations such as the area near LT11 at FASS. We envision Office of Facilities Management to build new Bioswales in NUS with our guidelines.

A green building is an environmentally sustainable building, designed, constructed and operated to minimize the total environmental impacts. In this project, we seek to investigate plausible solutions from the user’s perspective that can hopefully improve the energy efficiency and performance of green buildings in NUS in the long run. Based on our survey done within the NUS campus and secondary studies, we conclude that NUS users in general are not particularly aware of the concept of green buildings and this might have an implication on the overall energy efficiency and building performance of green buildings in NUS. Given that “significant progress in green buildings can only be sustained by understanding the changes to technology and the resultant user engagement with it”(Cole, 2003), we seek to examine plausible solutions based on existing technology that can sustain user engagement, so as to maximize the energy-saving potential of green buildings in NUS.

Due to increased fish consumption, practices of aquaculture have to be altered sustainably to feed this demand. We aim to investigate the likelihood of adopting sustainable practices of aquaculture and responses of consumers and fish merchants on shifting coastal fish farming to more sustainable means.Research was conducted on current approaches to aquaculture and concluded that change was needed on a national level. To ascertain consumer awareness we conducted surveys to deduce whether average Singaporeans would be open to supporting sustainable methods given that a premium or change in diet may be needed. We surveyed a total of 152 individuals across NUS and public. Results indicated that >70% of people surveyed (18-50) were unaware of current unsustainable practices and are keen to adopt sustainable means. We can conclude that it is likely for Singaporeans to embrace sustainable means of aquaculture, thus we should push towards generating awareness among Singaporeans.

In 2011, Singapore had 0.68 million tonnes of food waste, and only 10% was recycled. To put this into perspective, this means on average, each person in Singapore produced roughly 130kg of food waste in a year. In addition, the recycling rate for food waste has dropped from 16% in 2010 to 10% in 2011. We have over 90% of food waste still discarded. Initially we proposed a food redirection strategy that would collect potentially wasted food before being thrown away, and redirect it into different channels. Unfortunately, the pilot did not take off as we encountered numerous issues. Thus, we decided to investigate already existing food re-distribution channels provided by Food Bank Singapore and Food From The Heart to collect qualitative data on these existing system’s efficiency and effectiveness as well as evaluate its bottlenecks.

From our research, there were around 158,600 tonnes of textile waste generated in Singapore in 2014, of which only 11% are recycled. Our project investigates the recycling habits of RVRC students and actions on their unwanted clothes. Our pre-drive survey has obtained 50 student responses and showed that there are about 20-40% of students who wear less than 40% of their clothings. Also, 92% and 45% of respondents respectively are willing to donate and exchange unwanted clothes. Through this project, we focus on raising awareness of the importance of recycling unwanted clothes in RVRC. We conducted a clothes swapping drive on 18 February 2016 and 30-40 people turned up for the event. From the survey, we learnt that there is awareness present on reusing or recycling of clothes. However, we found that this does not necessarily translate to action. This may be due to the lack of incentives present.

Our project aims to address the sustainability of elderly care in Singapore. Current statistics show more Singaporeans retiring and a shrinking number of Singaporeans entering the workforce (due to our low birth rates). Our Old Age Support Ratio (OASR) is projected to fall to 2.1 in 2030, which is an indication of the ratio of able-bodied Singaporeans per dependent elderly. Not only will this problem lead to slower economic growth, it will also put a greater strain on the nations finances, with more welfare privileges given out to the elderly and less working adults paying income taxes. We seek to target the elderly who are living in areas with high elderly density. Our group will be focusing on active ageing and how it will promote healthy life expectancy. By doing so, the elderly become more independent and less reliant on other, which will in turn improve the sustainability of eldercare.

Due to global warming, global temperatures are rising. This worsens the urban heat island effect in highly urbanised environment. Due to building developments in NUS, vegetation is removed, creating more hotspots. To complement the roof gardens plan for buildings, we explored using creeper system on the bus stops near hotspots. This will increase greenery distribution, which will lower the temperature of the surroundings. Creeper system is remarkably simple and reduces the overall building and maintenance cost. Large scale deployment of green roof on lightweight structure is made possible. From the surveys conducted, there is a large support. However, awareness has to be raised on the advantages. Although some temperature data was collected from a similar setup, further isolated trials would need to be conducted to confirm the effectiveness of reducing ambient temperature. If successful, there could be an expansion of ideas to other platforms to increase the overall green coverage.

The DCP is a system which distributes thermal energy in the form of chilled water from a central source to a large bulk of consumers. It serves as an alternative to current air-conditioning systems in commercial buildings, which consist of individual chiller plants. In this project, we looked into the feasibility of the DCP as a future system of air-conditioning for commercial developments in Singapore, based on factors including economic costs, environmental impact, energy efficiency and government policy. As part of our research methods, we conducted interviews with key stakeholders, participated in site visits to existing DCPs, and surveyed existing literature on the subject over a duration of three months. From our research, we have arrived at three key learning points which can serve as an impetus for further developments in the study and implementation of district energy systems.

Incentivizing participation in public events, especially student activities on campus, is most commonly achieved these days through the distribution of freebies and ‘goody bags’. As first year students in NUS, we have thus far attended only a few student events but are already the proud owners of 4 goody bags each that currently reside at the bottom of our closets. The bag’s content were sorted and trashed upon at the end of the event because these items hardly come in useful beyond the event. The goal of our project is to scale down this mindless trash generation by designing and creating a digital branding platform since the smartphone ownership within the student bodies is high. This can be extended to other institutions, business organisations and on a national level, such as National Day Parade since “goody bags” are often the main lure for crowd.

Autism is a lifelong developmental disability that affects how a person interacts with other people (NAS, 2016). Caregivers of autistic individuals experience financial burden and emotional or psychological distress (Shu, 2009). In this project, we investigate the feasibility of an online platform in ensuring the sustainability of caregivers. The platform aims to facilitate interaction and allow caregivers to educate themselves, by providing access to the latest information on autism, all these while maintaining anonymity. To obtain feedback on the feasibility of our proposed solution, caregivers are surveyed to find out about their challenges, mindsets, and their needs. One improvement was to alter the target audience as we lack relevant skills to effectively assist autistic individuals. We discovered that we are in a better position to meet the needs of autistic caregivers. It was reported that a centralised information repository would help guide parents to provide better care for their dependents (Foo, Yap & Sung, 2014). Hence an online centralised information repository would cater to this demand.

Diesel buses, including NUS shuttle buses, emit fine particles (PM2.5) which are harmful to human health. In this project, we investigated the PM2.5 impacts of NUS shuttle buses and related health effects. Measurement of PM2.5 concentrations was conducted at University Town bus stop during peak (6.00pm to 7.00 pm) and non-peak (2.30pm to 3.30pm) periods for five days. During each period, we used DustTrack, an air quality monitor, and collected 24 data sets with an interval of 2.5 minutes. After applying humidity correction for raw data, we did statistical analysis to find the difference between the level of PM2.5 for peak and non-peak periods. The difference is not significant. Results for the PM2.5 impacts of NUS shuttle buses are inconclusive and further study is needed.

Combined Cooling, Heating and Power (CCHP) is a well-established method of power generation that can improve efficiencies from 59% to 88% (Liu et al., 2014). Despite this, CCHP systems are still not widely utilised in Singapore. Hence, this project seeks to examine the issues hampering the uptake of CCHP systems in Singapore. A site visit was initially conducted at GlaxoSmithKline’s CCHP facility. A meeting was also arranged with the National Environment Agency (NEA) and the Economic Development Board to discuss the formulation process of green policies and their current uptake trends. Issues such as high capital investment costs, low current oil prices and the need for high cooling and heating demands, and legal concerns were raised. Upon evaluation of these issues, we question if more efforts can be made to incorporate a push factor in policy-making to encourage greater adoption of CCHP in the long term.

Urbanization is currently increasing on a global scale, with world urbanization levels predicted to increase to almost 70% in 2050, increasing the isolation of agricultural land. This poses the issue of a lack of agricultural self-sustainability, especially in cities that do not produce crops, such as Singapore, which imports 90% of its food. In many cities, urban farming is becoming more popular as a solution, and our project aims to study the feasibility of running an urban farm on a rooftop. Our project will be an investigation in the scope of the NUS campus, assuming it to be a city , with the proposed rooftop sitting on S1 building at the science faculty. We will explore the aspects of the accessibility and safety constraints of the rooftop, green roof types, economic sustainability of the farm, and possible systems of maintenance which will involve students so as to promote social benefits.

The convenience and availability of plastic bags in Singapore has resulted in serious environmental issues such as the release of harmful greenhouse gases and threat to marine life. In this project, we carried out a “Free from Plastic Bags Day” to assess its possibility as a long term implementation in NUS. A survey was conducted from 11am to 7pm (on 16 March 2016) at Utown NTUC and UTown Guardian to gauge customer response towards the initiative. The results indicate that 95% and 70% of customers from Guardian and NTUC respectively are willing to support the initiative. With these data, the “Free from Plastic Bags Day” was executed (on 31 March 2016). Towards the end of the event day, short interviews were conducted with the respective store retailers to assess possible difficulties faced should a long term implementation be effectuated. All data collected was then consolidated and analysed to conclude possibility of banning single-use plastic bags and the continuity of such initiatives in NUS.

As a country that is highly dependent on importing food from overseas due to limited land and natural resources (approximately 90% of the food Singaporeans consume is imported [1]), continually innovating for solutions that will improve our food supply is imperative. Agri-Food & Veterinary Authority of Singapore (AVA), has ventured into high-tech agriculture to boost local production. According to the 2014/2015 annual report for AVA, 12% of the total leafy vegetables were produced locally [2]. Production of vegetables locally involve methods such as soil cultivation and hydroponics. Furthermore, 80% of the leafy vegetables produced locally are from soil cultivation [3].

Our team studied the challenges of growing organic vegetables locally as compared to importing it from overseas because the market for organic products has grown over the years [4]. We were able to determine the challenges that local producers face in growing organic produce.
