Stage set for two plants to con­vert waste to en­ergy

De­tailed fea­si­bil­ity re­port to de­velop plants in Perun­gudi and Ko­dun­gaiyur com­pleted

The New Indian Express - - CHENNAI -

THE de­tailed fea­si­bil­ity re­port to de­velop two waste-to-en­ergy plants in Perun­gudi and Ko­dun­gaiyur to gen­er­ate power by pro­cess­ing 5,500 tonnes of mu­nic­i­pal solid waste from the city per day has been com­pleted, ac­cord­ing to P Mad­husud­han Reddy, Deputy Com­mis­sioner (Health), Greater Chen­nai Cor­po­ra­tion.

Speak­ing at the two­day event ‘Ur­ban Thinkers Cam­pus Roadmap to Zero Waste in Chen­nai’ or­gan­ised by the Madras Cham­ber of Com­merce and In­dus­try, Reddy said that the site would be re­claimed and fresh waste pro­cessed through the power gen­er­a­tion plants.

The 32-megawatt-ca­pac­ity plants will incin­er­ate the waste which reaches the land­fill to pro­duce en­ergy. The op­er­a­tional and main­te­nance costs of the plants at Ko­dun­gaiyur and Perun­gudi are es­ti­mated at `1,243.50 crore and `1,163.43 crore re­spec­tively over a 20-year pe­riod.

“We will be pro­cess­ing 100 per­cent­age of waste through the in­cin­er­a­tion plant,” he said.

Cur­rently, the city gen­er­ates 5,500 tonnes of solid waste and 600 tonnes of con­struc­tion and de­mo­li­tion wastes each day, which is be­ing taken to the two dump­ing sites, he said, ad­ding that of the waste gen­er­ated in the city, 60 per cent is biodegrad­able, 20 to 25 per cent re­cy­cled waste and rest 10 to 15 per cent has to be put to land­fill or for in­cin­er­a­tion. Once the plants are op­er­a­tional, the waste in the 200 acres site will be cleared, Reddy said.

It is learnt the wasteto-en­ergy plants will be im­ple­mented through pri­vate-pub­lic part­ner­ship mode. The projects will be im­ple­mented over a five-year pe­riod, and bid­ding will be based on the de­sign-build-op­er­ate­and-trans­fer model.

Reddy also said the Chen­nai Cor­po­ra­tion had set up lit­ter bins in seven or eight places across the city on pi­lot ba­sis and urged the peo­ple to dis­pose of waste in the bins. He said govern­ment or lo­cal body can’t alone clear the waste with­out the co­op­er­a­tion of the res­i­dents.

He also high­lighted how the Swachh Bharat cam­paigns were be­ing held in city on par­tic­u­lar sites, which are usu­ally kept spot­lessly clean by the Chen­nai Cor­po­ra­tion. “The is­sue with the or­gan­is­ers is vis­i­bil­ity. If they come to us we could sug­gest sites which re­ally re­quire to be cleaned,” Reddy said.

Of the waste gen­er­ated in the city, 60% is biodegrad­able, 20 to 25% re­cy­cled waste and rest has to be put to land­fill or for in­cin­er­a­tion. Once the plants are op­er­a­tional, the waste in 200 acres site will be cleared
