DCB has targeted to achieve 100% waste segregation at source by March 2027.The environment department said MCD has created 680 zero waste colonies so far. It has also identified 3,965 bulk waste generators so far and out of which 1,995 bulk waste generators are having onsite wet waste composting facility.The report stated that of the total 12,500 tonnes per day (TPD) of municipal solid waste generated under MCD’s jurisdiction, there is a gap of 4,659 TPD (37%) in processing capacity.However, the civic body has proposed creating an additional processing capacity of 7,650 TPD through six plants by 2028 to bridge the gap and meet future requirements. Of these, new waste to energy plants (WTE) at Narela-Bawana and Ghazipur with a capacity of 3,000 and 2,000 TPD, respectively, are expected to be completed by Dec 2028.Expansion of the existing waste to energy plants at Okhla and Tehkhand with additional capacity of 1,000 TPD each is targeted to be done by March 2027 and Dec 2027, respectively.
