Kolkata: National Green Tribunal orders segregation of waste at the source
To ensure proper and scientific disposal, the Eastern Bench of the National Green Tribunal (NGT) has ordered that waste be separated at the source and that compactors be used sparingly for a particular category of waste throughout the areas under the jurisdiction of the Kolkata Municipal Corporation (KMC) and other urban local bodies.
Experts in waste management have applauded the NGT decision following the case brought by environmental activist Subhas Datta.
Sadhan Ghosh, a waste management expert at JU, stated that waste segregation, composting of kitchen and market waste, and material recovery from solid waste would assist civic bodies in achieving “zero-waste” and eliminate the need for dumping at landfill sites.
the court’s bench B The NGT’s Amit Sthalekar (judicial member) and Saibal Dasgupta (expert member) noted that only 27 KMC wards practise waste segregation. Since there are 144 wards in the corporation, serving just 27 of them (18.8%) is insufficient.
Additionally, they claimed that the civic organisation had set up hundreds of compactors, which completely undermined the idea and process of waste segregation.
The total cost of damage from contaminated groundwater, pond water, and soil is estimated at Rs 7.3 lakhs for a dump site the size of Dhapa.
Since KMC has already begun biomining at the Dhapa dumpsite in accordance with the NGT’s directive, further harm to groundwater and pond water should be kept to a minimum and under control. At Dhapa, approximately 2.4 lakh tonne of legacy waste have already been extracted.
In accordance with the NGT’s directives, biomining has also begun at 78 of Bengal’s 107 legacy dump sites, including the Promod Nagar and Mollar Bheri dump sites on the city’s northern and eastern outskirts.
However, the central pollution control board’s ambient air quality standards (measured in terms of PM10) are exceeded by pollutants from the dumpsite, costing Rs 1.3 lakh in damage each month.
According to the KMC affidavit, KMC is paying an environmental compensation of Rs 10 lakh per month because they have not yet fully complied with the requirements of the SWM rule of 2016.
One of the main air pollutants is methane gas, which is produced by solid waste and legacy waste dumps.
KMC has made the decision to build a 300 TPD material recovery facility in Rajarhat on a 5-acre plot of land through a public-private partnership.
