APPENDIX 2

Summary of the winning projects :

(A) PRIMARY LEVEL


3rd Prize S$1,000


Water Conservation Unit (WCU)

Daryl Lo Yin Keong, Shaun Lim Hsien Yang, Clifton Mathias Yeo Wei Keat

Project Summary

Our proposed Water Conservation Unit (WCU) is a wire-mesh structure that can be used for bus stops, pavilions or even covered walkways. When rainwater falls on the layers of wire-mesh that formed the roof, they would drip through but would eventually drop to the sides. Light would also go through. When the water drops to the side and as the structure is tilted, it would drop on a large pot of plants. To prevent the plant from drowning, the water would drip through a pipe attached to the pot and would be channeled into either a drain or a storage tank.

Merit Award S$500


Greenwave Proposal Jeremy Eu Zai Hao, Jeremy Wee Pang Ching

Project Summary

For water management, we thought about the underground reservoirs as there is limited land space in Singapore to build reservoirs. We could dig holes on the roads and cover the holes up with a metal cover with holes because metal is strong. There will be holes as the rainwater will flow down a pipe and it will lead the rainwater to an underground reservoir. The water will then be purified and then send to our homes to do washing, bathing and drinking but the water will have to be boiled just in case the water is a bit dirty. For air environment, we think that if there was a fan at the back of a car, it might reduce air pollution, but the motor has to be removed. The fan will need batteries and the fan must be strong enough to push the car forward and backward. There will be holes at the back of the car so that the wind will be able to push the car backward and forward. There is another fan behind the first fan because one is for reversing and the other fan is used for moving forward. There will be three buttons to control the speed of the car.

Jurong West Primary School

Removal of arsenic via phytoremediation using silver and brake ferns cultivated by tissue culture

Tang Hor Tyty, Teh Jie Xiang, Yeo Xin Ying, Chua Cheng Yong, Tan Ying Jie

Project Summary

Phytoremediation is a safe and inexpensive means of removing toxic chemicals from the soil through the use of plants. According to research done, the brake and silver ferns have the ability to uptake arsenic. Arsenic is a proven human carcinogen. The purpose of our project is to do an extension of the project started in mid 2003 where silver ferns and brake ferns were cloned using tissue culture method. The focus is on increasing students’ awareness of arsenic in the soil due to usage of fertilizers and pesticides as well as the method of using hyperaccumulating plants such as ferns to remove them. The tissue culture method allows the students opportunities to see the purpose of advanced techniques in helping to combat pollutants.

(B) SECONDARY LEVEL


2nd Prize S$4,000

Anglican High School

Saving our earth's water Teng Jin Zhi, Boo Chiu Suen, Alena Low Lixiang, Khoo Say Yien

Project Summary

Our project aims to create awareness among the public to keep our water clean from domestic waste. We will be focusing on how and what we can do as an individual to save our water as well as the understanding of how it affects people. By finding out the effects and causes of water pollution, we hope to achieve better awareness among public of the negative consequences that will result and thus, to improve the situation by educating them our ways to reduce water pollution. Our team came up with an interesting board game to promote and create awareness on water pollution. Together, hand in hand, we hope to save our Earth’s water.

3rd Prize S$2,000

Plants in Bishan Park 1 (1.4km jogging track)

Wong Hui Min, Teo Cui Fang, Ng Xian Hui, Heng Choon Kim, Choi Sin Yi, Ling Ming Quan, Tang Zhen Liang, Serena Ong Yu Ting, Yu Xue Ping Eileen, Eunice Tan, Ching Wai Ji, Lim Liang Wei, Wardchart Jim Randura, Reshmi Rai

Project Summary

To enhance the public’s knowledge of plants at Bishan Park 1 labeling them with attractive signboards and a brochure. This involved exploring the 2.4km jogging trail in the park and identifying the plants. National Parks Board will verify the plants identified before creative signboards are made and mounted in front of the plants. An educational brochure on this trail will then be produced.

Merit Award S$1,000

Nanyang Girls’ High School Is it really junk?: A proposed electronic waste disposal system

Deng Bowei, Vivien Chong Xin Yi, Thai Jiin- Shiuan, Tung Wanrong

Project Summary

Many of our household appliances are discarded in today’s “throw-away society”. These appliances contribute significantly to the increasing amount of waste generated everyday. Although a large proportion of discarded appliances are still functioning, people yearn for new products and willingly discard their obsolete products. This project reviews environmental problems raised by discarded household appliances, investigate the purchase, use and disposal of household appliances from the consumers’ and retailers’ perspectives, to provide quantitative research on product ownership, lifespan and routes of disposal of household appliances. This would help create a waste management plan that serves both consumers and retailers better.

Canberra Secondary School

A feasibility study of a rainwater collection tank in our school

Chia Yiwen Yvonne, Wong Lok Hang, Lim Yiwen Yvonne, Clarence Chew Wai Tuck

Project Summary

We are doing a feasibility study on the idea of having a “rainwater collection tank”. The objective of this project is to help our school cut down on its high utility bills. Firstly, we felt that the amount and quality of rainwater collected in Singapore would suffice rainwater as an alternative source for our basic cleaning needs. We did an analysis on how feasible this idea is and the results were very encouraging. Re-education is also another important aspect to reduce demand for water. We have also showed a variety of activities as to how this can be achieved.



Producing and marketing an organic ink

Tan Hui Hong, Cheong Shu Min, Lee Shi Min, Soh Yi Hui

Project Summary

We aim to develop an environmental-friendly white-board marker by changing the chemical solvents in common white board markers into organic solvents by extracting certain parts of plants. We decided to embark on this project because our teachers and friends find the odour from the school white-board markers intolerable. Research also shows that xylene which is commonly used as a solvent in white-board markers is harmful to health. We also package our white-board markers with slogans to encourage re-cycling, re-using and reducing.


Raffles Institution Handphone securing device

Yeo Wee Jin, Jarrod Tan Kah Hwee, Tan Cheng Yew Philip, Yan Cheng Jie

Project Summary

Students lose their handphones frequently and are not allowed to use a strap or pouch to secure their handphones in school. Hence, we designed a handphone securing device with a retractable string so that it can be kept in the pocket of student’s clothing. We make this device from used correction tape that many students are throwing away. The gears and casing of correction tape are used to make this device. The details of the device design and our findings on the cost of thrown away correction tape are detailed in our project.

Raffles Institution Natural filtration using water hyacinth

Foo Ming Qing, Brent Liu Jiankai, Lau Hui Ming Kenny, Soma Sundram Shivanesh

Project Summary

The aim of the project is to shed light on the filtration properties of water hyacinth and its potential use for sewage treatment. We conducted an experiment with two aquariums using water hyacinth plants to filter impurities from the aquarium water and another control aquarium using a conventional mechanical filter. The level of dissolved ammonia, nitrate, nitrite and pH level of both tanks were tested and compared.

(C) JUNIOR COLLEGE / INSTITUTE OF TECHNICAL EDUCATION/ CENTRALISED INSTITUTE LEVEL


3rd Prize S$3,000

ITE Dover Green Paper Lover Lee Shui Sing, Law Fook Sing, Engambaram, Mohd Muneer

Project Summary

In this digital era, paper usage and demand remains a problem which lead to a series of environmental issues like deforesting and changing of landscaping. To help reduce paper consumption, our team has developed a prototype to sort out paper that are still reusable from printer and photocopy machine. We hope this effort will encourage the development of more environmental friendly gadget and promote public awareness in saving the earth’s natural resources.

Merit Award S$1,000

ITE Dover Energy Recovery System Ang Ban Chong, Koh Lai Soon Kelvin, Loon Jinhui Steven

Project Summary

We are designing a device to recover some energy from an aquarium tank. This device consists of a small turbine which is connected to a generator. Pumped water from the filter will drive the turbine. The generated energy will then power some bright LED which will provide some light to the aquarium tank. This is a clean air system and will not cause pollution.


Catholic Junior College

Sustainable waste management in 'Green Schools'

Wong Wai Peng Hannah, Chiok Si Ling Aveline, Wong Li Qing, Xing Yimei Michelle, Hang Shu Min Celestine

Project Summary

Based on the present situation in our college, we have drawn up a more sustainable waste management system. We decided that the best way for any ‘waste management’ programme to be successful is through active participation. We tested out in our college by organizing an ‘Earth Week’ which was filled with many activities. From the results, we concluded that through awareness, waste management programme is more sustainable.

(D) TERTIARY LEVEL


2nd Prize S$6,000


Liquid & solid particles separator for ballast system

Tan Pei Wei, Lim Jia Jiunn, Wu Sheng Wei, Zhang Song, Chen Na

Project Summary

In the ballast (intake) water, there are many unwanted marine organism and particle. Transferring of those marine organism from one port to another port could cause harmful effects to the marine environment. The solid particles also cause sediment in the ballast tank. So we need to remove them before pumping them into the ballast tank. This project is a new separator device for ballast water system. It uses the theory of centrifugal force to remove larger solid from liquid, aiming to produce a practical which has high flow rate and higher efficiency for ballast water treatment. We have constructed a prototype of separator unit and assembled with other equipment.

3rd Prize

S$4,000


Water saving - hot water shower system

Han Ting Ting, Bay Sau Chuan

Project Summary

Our survey has shown that 70% of people in Singapore who use hot water shower would let the cold water run off till it becomes warm before bathing. We estimated that an average of 1 litre of water would be wasted per usage due to this bad practice. Based on a conservative figure of one-tenth of Singapore’s 3.5 million population taking hot shower once per day, there will be approximately 280,000 litres of pure water running directly into drains each day. To totally eradicate this waste, our system will only allow water run out of the tap/shower when its temperature reaches the user’s selected set point.

3rd Prize

S$4,000

Temasek Polytechnic

RoboGondola Cleaning System

Soong Chun Kai, Ong Say York, Tan Hui Fang, Wang Shaowei, Seow Shufen, Wayne Ng Weiren

Project Summary

For this Sembawang Shipyard’s Green Wave project competition, we demonstrated a conceptual design of a window cleaning system with steam cleaning technology to showcase cost effective means of water usage for washing and cleaning job. Using the Steam Cleaning technique will enable us to control water usage and reduce the splashing of dirty water during the cleaning process. This is in-line with ENV green objectives of Recycle, Reuse and Reduce.

Merit Award S$1,000


Living Canopy: Learning from the tropical rainforest

Wong Yen Loo

Project Summary

The proposal looks into the design of a roof system inspired by the tropical rain forest. The tropical rain forest represents lushness, fauna, shade and ecobalance. The Living Canopy is a roof system that provides the following benefits: - a) Shade b) Lush ambience c) Attracting fauna d) Collecting & recycling rainwater

Merit Award S$1,000


Cleaner discharge water from the kitchen sink

Zhang Yan Ling, Zhu Xiao Dao, Wei Hao Lin

Project Summary

The sink is a place where washing and food preparation takes place. Waste from washing and food preparation blocked the flow of water from draining off. For our project, we designed a device to catch the debris as the water flow down the drain pipe. The circular enclosed device has two internal strainers placed 180 degrees apart. One of the strainers is placed in the flow of the drain pipe and the other at the dry discharge pipe. The strainer in the water flow pipe will catch the debris. A manual external rod can be rotated to clear the debris at the dry discharge pipe.

Temasek Polytechnic

Energy recovery from hot air-con exhaust

Kenneth Lim Jian Long, Jovina Tan Si Yan, Nurul Huda Bte Hashim

Project Summary

Standing near to the compressor of an air-conditioning unit, one can feel the intense heat being omitted. This heat energy is thus wasted. The project aims to reuse this energy to heat up water for bathing purposes. A prototype is fabricated to prove the feasibility of this energy-conservation idea. It is found that a small window air-conditioning unit cannot generate enough hot water to take a bath. However, air-con units in large buildings are able to do so. It is hope that this concept can be implemented in buildings where air-conditioning and hot water are needed simultaneously, e.g. hotels.

CommendationAward S$500


Domestic Biodigester Kelvin Seet Chee Kiong, Chong Chon Hiong, Chin Soo Mun

Project Summary

The Singapore Green Plan 2012 stresses the need to venture into exciting and untried areas to ensure Singapore’s sustainability. It aims to recycle at least 60% of the waste and explore the different sources of energy. The project aims to help Singapore in achieving its goals. The Domestic Biodigester reduces the organic waste of household by anaerobic action. The digesting system consists of 2 main components; waste disposer and the digester. The waste disposer will pulverize the organic waste into small particles and feed into the digester for anaerobic decomposition. The whole system should sit nicely under the sink.
