Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing by up to 90 per cent compared to current toilet systems in Singapore.

Investigatory project: Alkyd Resin production from crude oil
Polymerization is one of the most important industrial processes. Resins and emulsion are two main classes of polymer. Alkyd resins are by far the most important class of coating resins. It is estimated that alkyd resins contribute about 70% to the conventional binders used in surface coating today. The popularity of alky resins as vehicle for coatings is largely due to their unique properties such as film hardness, durability gloss and gloss retention, resistance to abrasion, etc. impacted on them through modification with drying oil.

Investigatory project ideas : Land Fill gas to energy
Landfills are continuously producing and recovering landfill gas (LFG). Energy recovered from methane generated at a landfill displaces energy that is produced from fossil fuels, among other conventional sources of electricity.
