The East Delhi Municipal Corporation (EDMC) today told the National Green Tribunal that it has started fresh waste bio-stabilisation with microbial technology at the Ghazipur landfill site here.
The bio-stabilisation process converts all organic matter into useful compost.
In a report submitted before the NGT, the EDMC said that in pursuance to the green panel's directions, it has adopted the bio-stabilisation process as a pilot project taking into account the results obtained in Bandhwari dump site in Gurugram-Faridabad and other places.
"The agency has mobilised its resources and started sprinkling of bio-culture on fresh waste, made windrows of new garbage and deployed men and machinery for the purpose," it said.
It told the NGT that it has provided slotted vent pipes at an interval of 100 feet apart for release of methane gas so as to avoid accumulation of landfill gas.
"The leachate so generated from the garbage is collected in a tank. The same is filled in suction-cum-jetting machine having capacity of 4,000 litre and transported to the tipping area for recirculation. This machine makes 4 to 5 trips daily," the EDMC, through advocate Balendu Shekhar, said.
The civic body informed the NGT that it has started excavation of old waste, which is segregated in a ballistic separator having a capacity of 20 tonnes per hour.
"EDMC is already extracting landfill gas from part of the landfill and till date over 32.78 lacs cubic meter landfill gas from 21 boreholes has already been extracted part of which has been flared and from part of which electricity to the tune of 15-20 Kilo Watt hour is generated with the help of micro turbine imported from USA," it said.
The matter is listed for hearing tomorrow.
The NGT had yesterday rapped the National Highway Authority of India (NHAI) for not lifting segregated waste lying at the Ghazipur landfill site despite specific direction.
It had slammed the NHAI over the slow pace of finalising a tender to draft an agency to carry out the segregation of waste at the landfill site.
The strong comments had come in the backdrop of the September 1 incident in which a portion of the 45 metre high garbage dump in east Delhi's Ghazipur had collapsed due to heavy rains, killing two people and pushing a car and three two-wheelers off the road, into a canal.
The tribunal had earlier come down heavily on the AAP government and the EDMC over the Ghazipur landfill collapse, saying "nothing can be more humiliating than people being killed under garbage hill."
The green panel had issued notices directing them to show cause why punitive action should not be taken against the Delhi government and criminal proceedings not initiated against the erring EDMC officials over the "unfortunate" incident.
