Abstract

Improper treatment and disposal of municipal solid waste (MSW) and continuous increase in waste generation in India has increased greenhouse emissions as well as other pollutant emissions. In the present study, we analyse greenhouse gas (GHG) emissions from MSW management sector in India. We calculate GHG emissions for different treatment processes and then analyse the GHG emissions for waste management scenarios which reflect recycling, biological treatment and waste-to-energy (WtE). Our results show that annual GHG (CO2 -eq) emissions from urban MSW management in India is ~38 million tonnes/year out of which 94% is from open dumping alone. Increasing recycling to 50% from the current rate of 17.5% could reduce the GHG emissions by 17%. Similarly increasing biological treatment process, such as composting and anaerobic digestion, of biodegradable waste to 50% could reduce the GHG emissions by 12%.
