Chennai to bio-remediate Kodungaiyur and Perungudi dumpyards

The Chennai Corporation has finalized a proposal to bio-remediate Kodungaiyur and Perungudi dumpyard at a cost of Rs 1,250 crore. The New Indian Express reports that the proposal is likely to be reviewed by the Chief Secretary soon, following which, officials expect the remediation to start by next year. The civic body has scrapped its earlier plans of landfill capping since it was perceived to be unscientific.

Tenders have reportedly been issued to set up four bio-CNG centres to convert organic waste from both dump yards into bio-compressed natural gas. Four more bio-CNG facilities will be set up next year.

Civic authorities are also planning to use incineration and pyrolysis to tackle the landfill waste. Meanwhile, to process dry waste, the civic body has signed a Memorandum of Understanding (MOU) with cement factories. Dalmia cements gets 300MT of dry waste, plastic, and other burnable items daily.

As part of the remediation process, the civic body is set to create 100 acres of temporary dumping in Kodungaiyur and 50 acres in Perungudi.
