The ash generated from Waste-to-Energy Plants contains heavy metals and unburnt toxic chemicals which contaminates the underground water table.

To dispose of the ash produced by the WTEPs in Okhla and Tehkhand, the Municipal Corporation of Delhi (MCD) has constructed an ESL facility in Tehkhand.

The amount of trash (ash) to be disposed of daily is 100 tonnes, and this ESL has a capacity of 9.23 lakh cubic meters.

ESL is projected to live for 6.5 years, according to MCD.

Following the filling of ESL, MCD will begin looking for other land and in Delhi, land is an extremely valuable resource.

Consequently, bricks and other materials that can be used in construction operations must be made from the ash produced by all of Delhi's current waste-to-energy facilities.
