The waste to energy plants make use of the waste unfit for recycling and composting. The most common waste to energy technology used in India were Refuse Derived Fuel (RDF), biomethanation and waste incineration. Pallavaram and Tambaram municipalities are jointly setting up TN's first waste to energy plant based on RDF technology in Vengadamangalam at a cost of '100 crore along with an organic compost yard. The proposed plant would generate 2.9 mw of power a day from 300 tonnes. "In the first phase, the work on a transfer station cum material recovery facility using technologies to generate RDF and organic compost at the processing facility were completed. The work on plant will be completed in a year," a Pallavaram municipality engineer.
