vital that we use water wisely and should explore ways to ensure there is no water wastage either through public negligence or poor water system maintenace.
Water is precious national resource. Therefore, it is The project looks into two categories of water consumers. First the domestic and second the industrial category. Both systems primarily attempts to arrest water wastage. For the domestic system, the user would be able to detects water leakage easily and arrest water wastage. Avoid costly replacement of household items as a result of burst water pipes in an unattended house. Low cost investment under S$10 for a basic system. For the industrial system, the user would be able to: Monitor trends in Water utilization. Deter careless users who waste water deliberately. Arrest undetected broken underground pipes. Stop illegal tapping of water.

| Maintenance free solar irrigation system for gardens |
| Singapore Polytechnic |
| Augustine Ashley Santhanam, Thong Jie Ying, Ho Chia Yen |
Singapore is a garden city. Time, labour, water and resources have been expended in to make it green and attractive to visitors and a conducive living environment for all Singaporeans. It is the innate nature of many Singaporeans to play their part in beautifying their living environment. Many have tried their hand on keeping plants at their premises. Some were not able to sustain the daily routine of watering the plants. Some gave up due to their committed short stints overseas. Some have problems keeping the plants in a healthy state when the whole family go for a holiday. Our solar irrigatioin system is designed to address all these issues. It is specially designed with the Singaporean urban situation in mind, thus it requires as little set up labour and maintenace as possible. The system is both maintenance-free and environmentally friendly. Energy is tapped from the sun by using small solar panel and stored the energy in the lead acid battery. A DC pump is then used to pump the water to water the plants. The plants will be watered in the prescribed manner; specific times of the day and specific duration of watering.

| Conserving banded leaf monkeys (Presbytis femoralis femoralis) in Singapore: Exploring possibilities |
| National University of Singapore |
| Anbarasi Boopal |
The proposal to conserve the critically endangered Banded Populatioin Monkey found in Singapore, by augmenting the present small population with more individuals and captive breeding. The principal issues like non availability of habitat, low population numbers have been addressed in the proposal. Evaluation of already existing sites and identification of new sites have been done. Setting up of a banded leaf monkey centre, human assisted translocation of monkeys between two populations, use of assisted reproductive technologies have been proposed and discussed in the report.
Identification of new sites as habitats, human - assisted translocation between subpopulations to maintain genetic diversity, use of asisted reproductive techniques to support captive breeding and consider female-biased selection.

| Enhanced water broom |
| Ngee Ann Polytechnic |
| Marhayah Binte Jamaluddin, Desmond Choo Zhi Yuan |
The Enhanced Water Broom was fabricated to lighten the users work load while washing the floor. The function of the water broom is to spray wash the floor as well as brushing the floor at the same time. Normally, people will use water jet to spray the floor and use plastic broom to brush the floor after that. We believed that by using a normal water pressure through tiny openings are enough to bring out most of the dirt on the ground. The key features of the water broom are: Waterjet without electricity. Side guide to control and contain the debris for easy disposal. Rollers to make the room as mobile as possible. Ability to dismantle the broom and keep away when not in use. Brushes to scrub the floor. Low cost in production.

| Mosquito free roof gutter |
| Singapore Polytechnic |
| Ang Kay Khim, Lim Boon Teck, Ivan Tay Chin Boon |
Mosquito breeding grounds are often associated with the maintenace and stagnant water found in choked roof gutters. This project aims to study the maintenace and water stagnation problems in existing roof gutters and find solutions to reduce the environmental health hazards of mosquito breeding in roof utters. We have explored some innovative ideas to make the gutter easier to maintain and more importantly, free of water stagnation. We hope our mosquitoes free roof gutter could one day replace all the existing gutters, change the way these gutters are maintained and help to further reduce the numbers of mosquito breeding grounds for the environment protection.

| Conversion of food waste to energy |
| Nanyang Technological University |
| Vu Thu Trang, Huang He |
Accounted for 20% of the overall disposed waste in Singapore, however, only 7% of the waste was recycled while the rest was incinerated. To reduce the environmental problems caused by the incineration of food waste and to develop a new source of energy, the objective of this project was to develop a system which can convert food waste to fuel energy (biogas) in Singapore. The conversion process is done using the operation system developed in Nanyang Technological University, called the hybrid anaerobic solid-liquid reactors (HASL system). In the HASL system, methane production is enhanced and pollution is eliminated.

| Paper Multiplier |
| Temasek Polytechnic |
| Aldwin Su Duwen, Yip Yong Seng, Hee Zhen Zhen Lina |
The Paper Multiplier is a simple, low cost, hand-operated machine that recycles writiing papers directly into paper towels. I uses a pair of specially designed rollers to perforate and wrinkle a piece of paper to increase its surface area in order to absorb water or other liquid.
It is portability allows it to be used anywhere an anytime, for example at home, offices, industries and workshops.
This useful device saves the environment by reducing the paper wastage. It ensures that a piece of writing paper is fully utilized before being discarded.

| Recycling of used cooking oil to make soap |
| Temasek Polytechnic |
| Varinder Singh Bal, Toh Yi Da |
The improper treatment of used cooking oil from the catering industry can lead to water and soil pollution. This project aims to recycle used cooking oil to make soap. This would minimize waste treatment and disposal costs and conserve resources. The soap making process is environmentally-friendly as its utilizes used cooking oil as its raw material. This process would also reduce the detimental impact of used cooking oil disposal to t he environment. A pilot project was carried out in Temasek Polytechnic to collect used cooking oil from its canteens and convert them into liquid soap for use in dishwashing and floor cleaning.

| Carbon dioxide removals from car exhaust gas |
| Ngee Ann Polytechnic |
| Benedict Quah Chin Teck, Keith Fong Ri Sheng, Eugene Ng Pei Yong, Lim Wei Jin |
One of the main environmental challenges today is the avoidance of an anthropogenically induced climate change which can cause harm to human the ecosystems. To prevent this from happening, it was recommended that before 2100, the concentration of CO2 should be stabilized at 450 ppm. Fossil fuels account for 85% of world energy supply and it is used widely in the automobile. Therefor the aim of this project is to put forward a solution to remove or slow down the CO2 emission from car exhaust system.

| Fuel cell powered grass cutter |
| Ngee Ann Polytechnic |
| Shafiq Bin Sanip, Soe Min Htet, Brian Seah Chin Leong |
Our project is an attempt to exploit a number of technologies including solar, electrolysis, hydorgen storage and fuel cell which is known as in a renewable energy fuel cell system. This project uses hydrogen which is eventually used through fuel cell technology as an electricity source. The hydrogen in metal hydride cylinders are used to run the fuel cell. The fuel cell electrochemically converts hydrogen and oxygen from the air into water and electricity which is then used to power the lawnmower/grass cutter. The whole system does not depend on fossil fuel but hydrogen which is inexhaustible and renewable. It is also pollution free and environmentally friendly or "Green". Fuel cell will likely be a popular energy solution in the future.
