    Urban solid waste management refers to the planning concept with regard to proper disposal of solid waste generated in the urban areas. India suffers from a high burden of solid waste generated amounting to around 62 million TPA.
    Waste management is composed of the following individual processes:-

    1. Separation- This is generally carried out by the waste producers namely households, industries, other establishments at the point of generation. The waste is segregated into the following components-wet, dry and hazardous. the segregation is necessary to channelize the waste to wealth by recovery, reuse and recycle. The urban solid waste thus generated is handed over to authorized rag-pickers, waste collectors or local bodies.

    2. Collection- The local bodies are entrusted with waste collection, for the purpose of which they can include any other entity. The necessary infrastructure required for collection processes must be ensured by local bodies or waste generators.

    3. Treatment- Wet waste(biodegradable) will be utilized for composting/bio-methanation. Non recyclable waste will be utilized for generating energy either through Refuse Derived Fuel or by giving away as feed stock for making Refuse Derived Fuel using solid waste based RDF plant.

    4. Disposal- Solid waste remaining after the above processes will be dumped at landfill sites in an environmentally safe manner.
