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.

Industry Advisor: Sodexo

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.

Industry Advisor: UCI

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.

Academic Advisor: Mr. Lim Cheng Puay

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.

While the most recent Nielsen survey said that consumers in APAC were more willing to pay for a sustainable good/service as compared to those in North America and Europe, it is debatable if the willingness translates into actual buying by consumers, especially in Singapore. We conducted a study on whether students are willingness to pay a higher cost for sustainable as well as healthier menu options. Sustainable food options, could be low carbon, such as more plant based or reducing frequency of animal protein intake, supporting animal welfare, locally grown or raised, certified sustainable, and at the same time provide a well-balanced nutritional intake.

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.

Academic Advisor: Ms. Wong Kah Wei
Industry Advisor: Earthys

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.

Academic Advisor: Ms. Wong Kah Wei

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.

In 2015, Southeast Asian countries suffered one the worst haze. Since then, are Singapore consumers buying sustainable palm oil products to mitigate the haze?  This project aims to investigate if NUS students are purchasing sustainable palm oil products (SPOP). The project seeks to examine the reasons why NUS students may not actively decide to purchase SPOP. The project also aims to suggest ways to improve knowledge on the sustainable palm oil issue. 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.

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.

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.

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.

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.

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.

Academic Advisor: Dr. Chua Siew Chin

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.

Academic Advisor: Ms. Sadaf Ansari

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.

Bike-sharing programmes is a relatively new programme in NUS. To ensure its success, adequate resource allocation is required to support the bike-sharing scheme in NUS, one aspect being the implementation and positioning of additional bicycle stations. Our project aims to re-evaluate existing and proposed bicycle parking zones and propose additional suitable parking zones. To achieve this, our team worked on designing a matrix based on survey data obtained, and tested the matrix on UCI’s two newest stations to ascertain its effectiveness. We hope for this matrix to be a useful tool for UCI, and other organisations, in installing effective bike parking spaces.

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.

Water security has always been Singapore’s priority because of the lack of natural water resources. Our project aims to emphasize the importance of saving water in Singapore to children aged 5-6 years old. We will target this population in pre-schools, where children will be taught the importance of water in their daily lives as well as several methods in which they can conserve water at home. Our group has chosen to convey this message through a storybook, in which activities are included in it to allow students to have a more interactive learning. We have also come up with a teaching guide, to facilitate the teachers when using the storybook and activities during their lessons.

Academic Advisor: Dr. Chua Siew Chin

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.

The relationship between the built environment and walking behavior is well-researched through several empirical studies (Erwing R, 2010), especially due to its significance for creating sustainable urban solutions. 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.

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.

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.

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.

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.

Academic Advisor: Prof. Adekunle Adeyeye

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.

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.

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.

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.

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.

Academic Advisor: Mr. Lim Cheng Puay

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).

Academic Advisor: Dr. Chua Siew Chin

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.

Academic Advisor: Adekunle Adeyeye | Student Fellow: Kerk Jun Gang

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.

Academic Advisor: Sadaf Ansari | Student Fellow: Nicholas Tan

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.

Academic Advisor: Saif Khan | Student Fellow: Lee Juho

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.
