Can we produce electricity from waste?

Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. WtE is a form of energy recovery.

How much electricity does waste produce?

The typical range of net electrical energy that can be produced is about 500 to 600 kWh of electricity per ton of waste incinerated. Thus, the incineration of about 2,200 tons per day of waste will produce about 1200 MWh of electrical energy.
