The Corporation’s first bio-methanation plant, constructed at a cost of Rs. 90 lakh at Veeranam is expected to generate 400 units of electricity every day and serve the needs of three corporation buildings in the area.

Work is in progress to construct three plants to covert the biodegradable waste into electricity at Veeranam, Suramangalam and at Erumapalayam. Under the Integrated Urban Development Mission (IUDM) 2013-14, the plant was established at a cost of Rs. 90 lakh with the State government’s contribution of Rs. 81 lakh and corporation’s contribution of Rs. 9 lakh. The plant has the capacity to process five tonnes of waste per day.

Of the 320 tonnes municipal solid waste generated everyday in the city, more than 60 tonnes of biodegradable solid waste, including vegetables, banana trees and others, were disposed at Chettichavadi. Vegetable waste generated at VOC market is over 50 tonnes everyday and hence, it is the main source of raw material for the plant. By processing the waste, methane-rich biogas will be generated that will be used for tube lights and other electrical items at the Animal Birth Control (ABC) centre, for operating lights and motors in the nearby water tanks and public toilet in the area respectively.

Engineers said 1,250 tube lights, each 40 watts, can be operated for eight hours everyday using the power generated from the plant after considering transmission and distribution loss. Since, existing lights are converted into LED lights, the power from the plant could be used for more buildings, they added.

Construction of compound wall and flooring is expected to be completed in two weeks, after which the plant will be operated. Currently, trial run is in progress at the plant.
