Gaseous pollutant can take the form of sulphur dioxide, nitrogen oxide and many others. These could lead to deterioration in Singapore's air quality. The team's proposed strategy to combat air pollution is to remove the gaseous pollutants by either chemical or physical means.

Two main objectives of the team's experiment are firstly, to look into the possibility of using orchid roots as a natural membrane to remove sulphur dioxide and secondly, to review and study the effects of chemically enhanced orchid roots for the removal of the sulphur dioxide.

Singaporeans produce tonnes of waste everyday, which is incinerated, polluting the air and filling landfills. Much of this waste produced is biodegradable such as food waste and dead plant matter and these could be put to better use through composting. Composting is a relatively new idea in Singapore and if implemented, could potentially lead to several benefits and more importantly, could contribute towards protecting our environment.

The team designed a prototype of an economical composter for use in their school, using plant matter to produce humus, which could be used as a fertilizer for gardening in the school. The use of humus as fertilizer could also reduce the school's costs in the purchase of fertilizers for gardening.

Due to convenience and for hygienic reasons, many people prefer to use disposables materials. This project proposed to balance the modern needs of people and the environment protection. Trees protect our environment by preventing soil erosion and provide shelter for plants and animals. It also exchanged oxygen and carbon dioxide to renew our air. Hence, trees need to be protected as they are used to make the wooden disposable chopsticks throughout the world.

To save wood, this project designed and created a two part chopsticks, 2/3 recyclable and 1/3 disposable. This method could save 66% of the wood. By only using 33% of the wood, the replanting program can be sustained for long term use.
