1.1. Composting
Composting is one of the oldest methods of SWM. Composting is the biological decomposition of
organic waste such as food or plant material by bacteria, fungi, worms and other organisms under
controlled aerobic (occurring in the presence of oxygen) conditions (5).
The demerits of this process are that – it is a very slow process and can only be to organic waste.
Segregation of solid waste is very difficult. Hence this process is not very fruitful.
