NTPC Ltd, India's largest integrated power company, has partnered with Delhi Jal Board to utilise the sludge generation in the sewage treatment plants (STPs) in an effort to reduce the carbon footprint.
Green energy is generated from torified waste sludge at Unit 4 Boiler of NTPC at Dadri, a coal-based power plant in the Indian state of Uttar Pradesh. Based on green technology, this solution is a modern way to generate green energy from STP sludge in an environment friendly manner, which does not emit carbon dioxide.
The sewage treatment plant in Delhi-NCR alone generates 800 tpd of sludge. Disposal of this sludge is a big challenge as it causes large amounts of environmental pollution. It is also hazardous to the health of the people living in the nearby areas. By firing the sludge in the boiler itself, the emission of carbon dioxide will be reduced, which will reduce pollution. At the same time, green energy can be made from waste using eco-friendly methods.
NTPC is taking various steps to green its energy portfolio and has set a target of achieving 60 GW capacity from renewable energy sources by 2032.
