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.

| Water saving - hot water shower system |
| Ngee Ann Polytechnic |
| Han Ting Ting, Bay Sau Chuan |
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.

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.

| Living Canopy: Learning from the tropical
rainforest |
| Singapore Polytechnic |
| Wong Yen Loo |
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: -
- Shade
- Lush ambience
- Attracting fauna
- Collecting & recycling rainwater.

| Cleaner discharge water from the kitchen
sink |
| Ngee Ann Polytechnic |
| Zhang Yan Ling, Zhu Xiao Tao, Wei Hao Lin |
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.

| Energy recovery from hot air-con exhaust |

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.

| Domestic Biodigester |
| Singapore Polytechnic |
| Kelvin Seet Chee Kiong, Chong Chon Hiong,
Chin Soo Mun |
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.

Daylight is essential for
health and our daily activities. There are
instances in an architectural design there
are spaces that are too far away from the
source of daylight. The challenge is to bring
light from another space into the 'dark'
areas and minimize dependence on artificial
light.
Our team proposed the use of a device
that light-up dark areas like basement
carparks, long corridors without the use
of electrical energy. Light rods consisting
of a converging lens serve to harness and
diffuse daylight into the dark areas through
a silver or reflective lining within the
rods. The size can vary to facilitate the
extent of light required. It can be a web
or a path to light up the space and provide
a conducive environment.
