Compost is composed of organic materials derived from plants and animals that have been decomposed largely through aerobic decomposition. As compost is rich in organic matter, it can be recycled to be used as a fertilizer or in soil amendment. Compost is also a key ingredient in organic farming. Composting does not only offer the obvious benefits of resources efficiency. It also generates useful products from the organic waste that would otherwise have been sent to landfills.

The process of composting is not that complicated as it only requires gathering of organic matter and waiting for the materials to be broken down by microbes into humus after a period of time. The process of composting has been practised in home, in farms and even in a large scale by cities.




Aims and objectives
1.    To promote students’ interest in science through investigating the important parameters affecting the process of composting.
2.     To cultivate students’ creativity in developing small-scale composting equipment.
3.    To nourish the existing biology and bio-technology curriculum through a set of activity-based learning.
4.    To raise students’ eco-awareness in food recycling and promote “Green Life”.
