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.

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: 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.

AY1819G44 – “Generating a reliable source of pico-hydroelectricity in campus”

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.

Academic Advisor:  Mr. Lim Cheng Puay

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: Dr. Chua Siew Chin

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.

Academic Advisor: Dr. Chua Siew Chin

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.

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.

Academic Advisor: Prof. Adekunle Adeyeye

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

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.

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.

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.

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.

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.

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.

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.

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

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.
