India, Jan. 9 -- The National Green Tribunal (NGT) has flagged serious lapses in Delhi's solid and liquid waste management, observing that its 2023 order directing the state government to submit regular and verifiable compliance reports had not been followed for a considerable period.

Highlighting the scale of the problem, the tribunal noted that while Delhi generates around 11,000 tonnes of solid waste daily, it has the capacity to process only about 8,000 tonnes, leaving nearly 3,000 tonnes untreated each day. Similarly, of the 792 million gallons per day (MGD) of sewage generated, treatment capacity stands at only 704 MGD, with nine sewage treatment plants (STPs) found to be non-compliant with prescribed standards.
