The methane gas plant at the Ghazipur landfill site is likely to shut down soon.
The plant was installed five years ago by the East Delhi Municipal Corporation in collaboration with GAIL, to capture methane gas from the solid waste at the dumpsite. However, the department recently found out that the capacity of the plant to generate methane and other gases reduced by more than 50%.
“Methane gas is generated with the decomposition of bio-degradable waste. But we have detected that the solid waste dumped at Ghazipur landfill site has turned old and decomposed completely. It is no longer useful to generate enough gases,” said Pradeep Khandelwal, chief engineer, EDMC.
He pointed out that the contract with GAIL for the methane gas plant was over two years ago. “We have already overused the facility so there is no point continuing with the same,” he said.
The EDMC has signed a memorandum of understanding with NHAI, the ministry of urban development and the ministry of surface transport for using the solid waste at the landfill site for widening NH 24.
The project also includes reclaiming 70 acres of land .“Work on this project will begin by April 2017 and then the gas plant will be of no use for us,” said the official.
Methane gas is highly flammable and found in massive amounts at landfill sites due to the mixing of different types of chemicals. The gas catches fire as soon as it comes into contact with oxygen.
The civic agency has been capturing this gas to generate electricity.The power generated is used for running equipments at landfill site.
“Initially we were flaring the gas in the environment, but last year, we installed a unit to generate electricity from the methane gas,” said a senior EDMC official.
