The trial incineration of 10 tonnes of waste from the Union Carbide plant in Bhopal, responsible for the 1984 gas tragedy, began on Friday afternoon in Pithampur, Madhya Pradesh. The process, ordered by the Madhya Pradesh High Court, is expected to take 72 hours to complete. The waste includes soil, reactor residues, pesticide residues, and other materials. The State Pollution Control Board says the chemicals in the waste have become "almost negligible" and there is no presence of methyl isocyanate gas. The incineration process is being monitored by the Pollution Control Board and broadcast live.
