Waste to Energy

aftermath of plague in 1994 there was a change in the
attitude and approach of the Surat Municipal Corporation
and the citizens and the recent Swachh Sarvekshan 2019
brought Surat some happiness though the city could not
push itself to be among the top 10 cleanest cities in the
country, the city remained in the 14th position as in the
previous year. But the problem remains in Waste disposal
and not collection.
Waste generation in Surat:
Over the years municipal solid waste has increased from
865 MT in 2002 to nearly 1800 to 2100 MT in 2017.
The Problem                                                    Incineration is a waste treatment process that involves
