New Delhi: In an endeavour to reduce the carbon footprint, the  NTPC Ltd, India’s largest integrated energy company, has come together with Delhi Jal Board (DJB) to utilise the sludge produced in the sewage treatment plants (STP) of DJB.

The torrefied waste sludge was fired from NTPC’s unit 4 Boiler at Dadri. This green technological solution is an innovative way to convert STP sludge into energy via environment friendly means to reduce CO2 emissions.

In Delhi NCR alone, the STPs produce up to 800 MT of sludge per day. The disposal of this sludge is a major challenge as it contributes towards environmental pollution.

It also poses a major threat to the health of the people residing around the area. Firing sludge in the boiler will reduce net CO2 emission, and water and land pollution and will pave the way to utilize the waste and convert it to energy in an environment friendly manner.

The NTPC is taking various steps to make its energy portfolio greener and plans to have 60 GW capacity through renewable energy sources by 2032.

The total installed capacity of the company is 68,881.68 MW having 23 coal-based, 7 gas-based, 1 Hydro, 19 renewable energy projects. Under JV, NTPC has 9 coal-based, 4 gas-based, 8 hydro and 5 renewable energy projects.
