It is the separation of different type of waste materials like biodegradable and non biodegradable wastes.

Sanitary landfill:

Solid Wastes are dumped into low lying areas. The layers are compacted by trucks to allow settlement. The waste materials get stabilised in about 2-12 months. The organic matter undergoes decomposition.



Biodegradable matter of solid wastes is digested by microbial action or earthworms and converted into humus.

Recycling of Wastes

Agricultural wastes like coconut shells, jute cotton stalk, bagasse of sugarcane can be used to make paper and hard board. Paddy husk can be used as livestock fodder. Cowdung and other organic wastes can be used in gobar gas plant to provide biogas and manure for fields.
