Solid waste can be of two types -- biodegradable or organic and non-biodegradable or non-organic. Whereas organic waste includes mainly kitchen waste, straw,
hay, paper and animal excreta, non-organic waste includes ash, stone, cinders, plastic, rubber and ferrous and non-ferrous metals.
The data collected by the National Environmental Engineering Research Institute (NEERI) from 43 Indian cities indicates that, due to the common practice of using fresh vegetables and fruit, the waste content of garbage in India is highly organic. It varies between 40-50 per cent.
