In its status report on the bioremediation and bio-mining process at three landfills in Delhi, the Central Pollution Control Board (CPCB) has informed the National Green Tribunal (NGT) of several lapses. As per the report, despite trommel machines being used to screen legacy waste, the segregated waste is not being picked up, leachate is still seeping underground and the solid waste management guidelines are not being followed at Okhla, Bhalswa and Ghazipur sites.
The Times of India reports that CPCB said waste stabilisation through bioremediation was currently only being practised at Okhla where bio-culture had been sprayed. However, fumes were still being generated while moving the waste, indicating that the process was yet to be completed, it added.
The CPCB submitted this report in compliance with an NGT order of November 2019 following reports of leachate from the landfills contaminating the groundwater and was also seeping into the Yamuna.
