NTPC, India’s largest integrated energy company, has partnered with Delhi Jal Board (DJB) to use sludge produced in DJB’s sewage treatment plants (STP) to help reduce carbon emissions.
The waste sludge was torrefied and fired from NTPC’s unit 4 Boiler in Dadri. This innovative green technological solution converts STP sludge into energy in an environmentally friendly manner, reducing CO2 emissions.
Sewage treatment plants in the Delhi NCR alone produce up to 800 MT of sludge per day. The disposal of this sludge is a significant challenge because it contributes to pollution. It also poses a serious threat to the health of those who live in the surrounding area. Sludge combustion in the boiler reduces net CO2 emissions, water and land pollution, and paves the way for waste to be recycled and converted into energy in an environmentally friendly manner.
NTPC is taking a number of steps to make its energy portfolio more environmentally friendly, with the goal of having 60 GW of renewable energy capacity by 2032.
The company’s total installed capacity is 68,881.68 MW, with 23 coal-fired, 7 gas-fired, 1 hydro, and 19 renewable energy projects. NTPC has 9 coal-fired, 4 gas-fired, 8 hydro, and 5 renewable energy projects under JV.
