1st Prize S$6,000 Raffles Institution A collection of short children's stories - Terrestial Tales Samuel Tan Dao Ming, Manish Nair, Peh Shing Bo


Project Summary

The aim of our project is to create an educational book for children (aged 6 – 8) about wildlife, with illustrations and text. We chose children as our target audience because they are more impressionable and thus open to changing their daily habits and become more environmentally friendly. Altering the mindset of a younger target audience is also more significant as its effects will last for years to come.

Research will be conducted on endangered wildlife in Singapore. Following this, the information will be simplified appropriately to suit the target audience. Finally, the product will be created, incorporating an angle promoting positive sentiments about wildlife conservation.

Our compilation included five original stories encompassing the areas of overconsumption and wastage of non bio-degradable materials. These stories were modeled in part after long ‘ballads’ by Tim Burton and Roald Dahl, the latter who concentrated more on social problems through his numerous children’s stories.

Thereafter, our educational book will be tested out among children of the stated age group, and an analysis of its effectiveness would take place. The submission would consist of our research material, the educational book, as well as our effectiveness analysis.

Project Summary

Our project explores the effectiveness of constructed treatment wetland in treating greywater collected from toilet sinks. Our school has already set up a constructed treatment wetland, and we have had conducted tests and took readings to determine the effectiveness of the constructed treatment wetland in removing chemicals such as nitrates and phosphates, and also its effectiveness in removing pathogens such as coliforms. Other parameters such as turbidity, biochemical oxygen demand (BOD), total dissolved solids (TDS) and pH are also being considered for the analysis of the final water output. We want to show that the treated water from the Constructed Treatment Wetland (CTW) is clean and safe enough to be used for gardening (watering plants), for our fish ponds and for many other uses.

3rd Prize S$2,000 Bukit Panjang Govt. High School Recycling potato peels Kho Jie Min, Chua Kee Leng, Kong Qi Yuen, Ow Bao Yi, Cheng Heng Perng


Project Summary

Everyday, tons of potatoes are peeled and their skins are thrown away as they are deemed as useless and treated as rubbish. We wanted to recycle the potato peels into useful products. Potato peels, just like the flesh, contain high level of carbohydrates, minerals and other nutrients. This is perfect for ethanol production. By recycling the potato peels, we will fully utilise the potato peels as a whole without creating waste.

Our project consists of five semi-projects. Firstly, we fermented potato peel, which was blended with distilled water, into ethanol. The ethanol was used as pesticide. Secondly, we dried fibres that was sieved from the blended suspension and used them as plant fertiliser. Thirdly, the potato peels were left to dry naturally under the sun after washing. They were then grinded into flour which can be used to bake cookies or cake. Fourthly, we add ethanol to the sticky substances obtained when boiling the flour obtained in water, to make glue. Finally, after boiling and blending the potato peels, they were divided into two portions. One portion was left to dry under the sun and the other portion was grinded together with fresh grass and dried in the sun. Two different types of animal feed, one for pigs and the other for cows and other grass-eating animals were thus made.

We have successfully used potato peels to develop five valuable products, namely ethanol, fertiliser, flour, glue and animal fed. Besides reducing food waste, we have also reused and recycled potato peels.

3rd Prize S$2,000 Raffles Institution Green busTOPs Nigel Fong Jie Ming, Daniel Tan Wei Jie, Jeremy Sia Jia Rui, Marc Tan Jia Renn


Project Summary

This project raises the novel proposal of growing plants on top of bus stops in three possible configurations:

(1) growing creepers on a mesh
(2) growing plants in a soil layer, and
(3) growing plants in a bed of coconut husks as an environmentally-friendly substitute for soil

We then elucidate the detailed structure, suggest possible plants, and propose the maintenace requirements of each configuration.

The conversion of Singapore’s existing busTOPs into green busTOPs, together with related measures like public education and corporate adoption of busTOPs, so as to generate direct environmental benefits, and more importantly promote environmental awareness and action, and contribute towards urban beauty and identity. Initial cost, technical feasibility, and ease of maintenance may pose several problems to the wide-scale implementation, but we have shown that these issues can be easily mitigated, such that on the whole, they are insignificant juxtaposed against the benefits of green busTOPs.

We would strongly advocate the wide-scale implementation of green busTOPs. In today’s urgency of acting to promote environmental sustainability, green busTOPs will most importantly demonstrate fervent political will for this cause, and demonstrate how small actions can go a long way to overcome the tragedy of the commons, while at the same time generating a myriad of other benefits that in themselves justify the costs. We are optimistic that the message of enviornmental consciousness embodied by green busTOPs, if implemented, would start a ripple effect and eventually provide individuals and corporations with the moral and practical impetus to walk towards environmental sustainability.

Project Summary

Recycling of computer MOTHERBOARDS – When a computer reaches it shelf life, it is condemned by throwing it away or selling it to karang-guni man who will still thrown them away if there is no demand for it. By reusing the motherboards it will saves money and conserve resources. With this we hope we could spread the message of conserving resources and preserving the environment.

We felt that we could do something to renew the life of the motherboard especially most of the time the computer does not work is because of the had-disk and the monitor. The motherboard and its power supply is quite a hardy piece of equipment. We can savage the motherboard and try to reuse it. We know that from the internet, using a USB device, we could boot the computer and use it. There is no need for hard-disk with the newer technology. Using free software like Linux and openSource software we can try to reuse the old motherboard instead of discarding it away. We intend to make a wooden housing to house the old motherboards and relocate it in the Science Lab for students to use.

Project Summary

Presently, harmful and toxic chemicals such as chlorine and hydrogen peroxide are being used in the paper-industry for the deinking-process of waste paper. Such chemicals often pose as an environmental hazard as they contribute to water pollution, resulting in the deaths of aquatic life forms. Therefore, to counteract this pollution problem, our project focused on the study of a more efficient and quicker alterative to the use of harmful chemicals by replacing them with a more efficient method of enzymatic deinking.

Our project seeks to meet two objectives, namely to study the effectiveness of combinations of enzymes in deinking different grades of inkjet-printed paper as well as to work out a suitable combination of different enzymes for the deinking of different grades of inkjet-printed paper and determine the optimum conditions for the process. Our results show that there was a considerable decrease in brightness index of the reconstituted paper that had undergone treatment. Deinking was most effective when a combination of enzymes was used. Hence in our study, we have illustrated that enzymatic deinking is an environmentally friendly and effective way to recycle paper.

Project Summary

Tea is a popular beverage. Large amount of tea leaves are discarded, leading to the loss of precious substances such as caffeine, catechin and melanin which are still present in the waste tea leaves. Our project aims to recover these useful chemicals from waste tea leaves.

Results showed that all the 3 chemicals could be extracted from waste tea leaves. Yield of melanin was greatest while waste green tea leaves gave the greatest yield of all the 3 chemicals. Waste tea leaves were also successfully converted into black ink which can be used for painting or writing. Other ways of recycling waste tea leaves were also explored.

Our aim is to promote the awareness of 3Rs (Reduce, Reuse and Recycle), we came out with proposals suitable for recycling waste tea leaves at homes, schools and industries.

Merit Award S$1,000 Hwa Chong Institution Mangrove reforestation educational kit Lum Shu Hui, Lew Gui Qi, Shaina Neo Hui Min, Lydia Tiong Fang Min, Koh Wei Ling, Mavis Tan Qiu Yu


Project Summary

Our project aims to generate awareness of mangroves and the means to obtain reliable experimental data through outdoor experimentation. We purpose to do so by producing a portable and easy-to-use educational kit and related material to facilitate the acquiring of this information. We intend to target young children between the ages of 10-12 years of age. Through this project, we hope to foster these children’s interest in the conservation of the environment so that they may play a more active role in protecting it, as well as equip them with the necessary knowledge to become active stewards of our environment.

Thus, we can make quiz cards, which may include riddles, crossword puzzles, mangrove-related frequently questions and fun facts!

Also, we can create pictorial storybooks containing various short stories which are interesting for school children to read. This would appeal to booklovers and also to Primary 1 to 3 children who prefer reading pictorial to wordy books.

We understand that Sungei Buloh Wetland Reserve has been very dedicated in increasing the exposure of mangrove ecosystem to young school-goers. Thus, we would like to work with them in such a way that students would be able to possess a greater understanding and knowledge about mangroves and how to go about protecting them. Captivating and educational trips to places such as this can be organized in conjunction with Primary Schools.

Merit Award S$1,000 Raffles Institution The Green Book Joel Soon Jia Yi, Poh Chu Yong, Gan Zi Jie, Varun Vijayraghavan


Project Summary

Environmental problems such as global warming, desertification etc. are rampant in our society today and are one of the greatest threats that our planet faces today. These problems arise mainly from ignorance regarding good green practices and environment conservation. We plan to educate children in primary schools about these issues in a fun an interactive way that is suitable for their age group.

The aim of our project is to :
- raise awareness about environmental damage to children through stories and an ABC charge
- educate children regarding green practices
- ensure that the product is attractive for children and parents will be willing to spend

Thus we brainstormed for possible methods to convey green messages to the target audience. Some of the medium which we could convey these messages were through visuals, aurally or through activity. We decided on using short stories and adaptations of fables as these are the best in captivating children’s attention. Even at adulthood, many still remember childhood fables and folktales they heard or read when they were young, thus these types of stories can be remembered most easily by children. We also decided to use a lot of pictures and illustrations in our books as pictures can be recalled very easily and make the book more attractive.

This will be in the form of “environmental Fables” that will contain stores that bring about the importance or saving our earth. There will also be an alphabetical chart that touches on global warming and environmental conservation.

Merit Award S$1,000 River Valley High School Where are the Herons? Cassandra Sim Li Ying, Lim Pan Yin, Low Gar Yim, Zoey Ang Zuo Yi


Project Summary

Through this project, we wish to find out the status of herons in Singapore whether the number has been decreasing over the years and whether it has become a rare species in recent years. Our main purpose is to promote the conservation of herons in Sungei Buloh Wetland Reserve and also in Singapore among secondary students by creating educational materials like brochures.

We had a heron survey to find out the awareness of people on herons. We decided on a sample size of 236 participants, which targets people of all ages and occupations. The proportion of males and females are made equal. The survey lasted for two months. We distributed the surveys in school and randomly selected a few students from each level.

In addition, we also conducted the survey with visitors in Sungei Buloh Wetland Reserve when we went there for the heron census. This allows us to have a wider sample size of audience and also helps to ensure that biasness were not introduced into the data, which will undermine the validity of the findings.

This survey is done for two purposes. Firstly, it is to find out if people have the awareness for herons, so as to enable us to come up with brochures later to increase the awareness and conservation ideas about herons. Secondly, is that we want to know whether anyone has seen any herons in any areas of Singapore. Our group is more interested in the survey results from mainly students. This is due to the fact that our target audience for our products are students.

Commendation Award S$500 Anglo-Chinese School (Independent) 12 Simple Ideas for Green Improvement in HDB Flats Loh Guo-yang, Kurt Lydon Dee Tanyu, Mervyn Lim Jun Rui


Project Summary

In this modern society where resources are scare, conservation of the environment takes first priority. We believe that the general population plays a pivotal role in helping the protection of the environment. Hence our project recommends changes in the HDB estate; this will not only save a large amount of energy but also raise awareness within residents on the importance of having an eco-friendly lifestyle. Through this, we hope to raise awareness within the entire general population.

Our 12 ideas we are trying to introduce are often SIMPLE in nature, infact, some are also cheap to implement, yet all these ideas bring about large savings in energy. The ideas presented are also often unobstrustive, that is, the residents are allowed to continue with their normal lfiestyle. By integrating residents with an eco-friendly lifestyle, we believe that this would encourage residents to further the cause of green protection.

Below is a succinct summary of our 12 ideas:

1. Louver Gates – To increase ventilation and decrease overall temperature.
2. Rooftop hydroponics garden – To decrease the temperature of building, and to act as a decorative area and lastly to foster bonds within the community.
3. Colour of HDB – To decrease the overall temperature of the building
4. Aluminium Foil lights – Prevents energy from being wasted and increases the intensity of indoor lighting.
5. Larger tiles – Reduces the time taken to wash bathroom tiles and reduces water wastage and pollution
6. Artificial intelligence lifts – Prevents wastage of energy though an algorithm system and prevents the wastage of energy on putting the lift to standby mode during ‘non peak’ periods.
7. Dual Waste Chute system – Allows residents to recycle at the convenience of their home, encouraging residents to recycle and reduce the wastage of resources.
8. Two-way Sink system – To save the residue water through a simple motor mechanism for other future use such as watering plants, this conserves water.
9. Reflective curtains – These curtains scatter and reflect heat away yet maintain the interior façade of the house, reducing the overall temperature.
10. Green lobbies – Increases air quality and becomes an area for rest and recreations.
11. Aluminum Fins with plants – Reflects heat and disperse rain hence window can be continued to be opened even during a rainy season.
12. Pay-per use Electricity meter – Reduces the amount of carbon emissions as residents are more conscious about that energy bill and reduce the need for paper bills.

Commendation Award S$500 Hwa Chong Institution Potato Peel as Natural Adhesive Hunter Phoon Wai Kit, Daryl Ho Ze Wei, Nicholas Ren-Jie Capel


Project Summary

Potatoes have always been an essential part of our diet, be it mashed, cooked or deep fried and are a very popular food item on the menu of many restaurants today. Due to high consumption of potatoes, large amount of potato peel is generated by restaurants, fast food outlets and industries. However, a large amount of waste is generated as the potato skins are not used. These waste potato peels contain a heterogeneous mixture of water, protein, fiber, and starch which can be recycled and reused.

Starch has been widely used as adhesives. Adhesives are materials that are capable of fastening two other materials together by means of surface attachment. A well-known class of adhesives is based on starch and dextrin. They play an important part in industries, especially the packaging industry. This is due to their ability to adhere two substrates together to form materials that have greater mechanical strength. By bonding with starch based adhesives, most of the corrugated cardboards and packaging material we see today are made.

Starch and dextrin adhesives are commonly used because they are readily available, low in costs and easy to use upon water dispersion. This makes them the cheapest form of paper packaging adhesive that we can use in large-scale operations in the factory. Starch-based adhesive is highly versatile as well, as it can be customized to be used when it is hot or cold, and have a very slow curing rate which allows ample assembly time.

Project Summary

Our product is a website, Guni-Bay, that serves to bridge the connection between rag-and-bone men, and the general public, in order to faciliate the proper disposal of waste, including e-waste.

Furthermore, the website has the additional benefit that users or even the non-participating web surfer would be able to gain much information regarding recycling, electronic wastes, and related items. This would be catalyzed through the information library that the website hosts. Through this awareness-raising concept, we hope to be able to impact more people, thus promoting environmental awareness and contributions.

In this project, we seek to facilitate the communication between residential consumers and Karang Guni men so as to compensate the lack of convenience and motivation which recycling companies has. We seek to make transaction of items on Guni-Bay fast, easy and low-risk through efficient website layout, publicity and security features and precautions. We also seek to raise awareness of electronic waste and its disposal. Overall, this project aims to reduce the inconsiderate disposal of electronic waste by encouraging residential consumers to sell their electronic wastes to Karung Guni men.

Project Summary

We chose this title not only due to the pun of TOFU in the four initials of our title, but also to highlight how important Okara is in production of tofu as well as how it can be used even to a higher extent than what it is used now.

Through this projec, our objective is to convert Okara as a waste product into a main supplement of fertilizers that can be sidely used, so as to decrease the reliance on conventional fertilizers that are used presently as well decrease the run-off of Okara due to its wastage after the production of Tofu. To fulfill our objective, we embarked on our projects in the form of a survey, experiment. Through this, we formulated our product that would fulfill the objectives of our project, as well as bring a close to our project.

We embarked on the survey to find out the views of the common population of the use of fertilizer, and also tried to find out the various preferences on fertilizer of the Singaporean populace. The survey was conducted on 30 people of varying age groups. Finally, we basically found out that Singaporeans would prefer having a cheaper and more abundant source of fertilizer that would be easier to use and buy.

Encouragement Award S$200 Anglo-Chinese School (Independent) Producing Energy from Organic Materials through Winogradsky Columns Daryl Lo Yin Keong, Michael Sia Zhen Wei, Julian Brendan Tok Jun Feng


Project Summary

A windogradsky Column is a mixture of mud, water and a nutrient source, forming a ecosystem in which bacteria thrive. The bacteria in the column are interdependent on each other, in a process by which electrons are transferred, thus, it is possible to generate electricity. For our research, we intend to test organic material such as fruit peels and others which are commonly discarded, as a substitute for the nutrient sources of the column. This project thus will examine a new form of clean energy generation, while also contributing to and possibly helping to expand the recycling effort. The columns would also help to reduce use of dry cell batteries as they have the same functionalities, and thus, this also reduce the problems of elctronic waste.

Project Summary

Through this project our group aims to promote awareness about the destruction that mankind has wrought upon the earth and Mother Nature, through this poetry anthology. We also hope that the profits from sale of our poetry anthology can be used in the future to aid in mankind’s effort against environmental change. The poetry anthology consists of a wide variety of poems about our hopes, our concerns and our fears – with regard to environmental change. Although this poetry anthology is targeted mainly at teenagers and adults and how these groups of people can actually be agents of positive change, we hope that the greater message of environmental change will still be passed on to children and elderly alike. More broadly speaking, to fight environmental destruction, we need all – regardless of age, gender, nationality, race, religion etc. – to stand up, and to articulate in one voice, their wish for a sustainable future.

Project Summary

The main aim of our project is to tackle the problem of pollution (mainly land and water) and deforestation as well as some animals became endangered as a result of the above.

We focused on 2 major areas. Firstly, on increasing the population of some of these endangered animals - We have designed a nature reserve that would suit and provide natural living conditions for the survival of different species of endangered animal and allow them to produce offspring to ensure the survival of their species.

Secondly, on promoting the awareness of these issues to the public so as to get them involve in contributing to the prevention of deforestation and pollution – We have 3 solutions.

1) A website that will provide information about the endangered animals.
2) Through organising events, such as, Eco Festival and Eco Olympics, these will provide a wide range of different activities to cater to the different group ages.
3) Draw up lesson plans on poster to show various types of fun activities that can be used to educate children on the seriousness of environmental issues.
