The High Court later directed the Centre and the state that the toxic waste should be incinerated after tests at Pithampur in MP's Dhar district.

Later, the Supreme Court directed that the waste should be incinerated at the Defence Research Development Organisation (DRDO) facility near Nagpur. But, NGOs protested again in Maharashtra following which the state government expressed its unwillingness in court on the issue, he said.
