Meanwhile, in Bhopal, nearly 230km (143 miles) away from Pithampur, activists argue that the disposal process is a distraction from much larger issues.

Since the disaster, the toxic material lay in the mothballed factory for decades, polluting groundwater in the surrounding areas.

More than 1.1 million tonnes of contaminated soil remain at the Union Carbide factory site, according to a 2010 report by National Environmental Engineering Research Institute and the National Geophysical Research Institute.

“The government is making a show of disposing of 337 metric tonnes while ignoring the much bigger problem in Bhopal,” said Nityanand Jayaraman, a leading environmentalist.

“The contamination has worsened over the years, yet the government has done little to address it,” added Rachna Dhingra, another activist.

Government estimates say 3,500 people died shortly after the gas leak, with over 15,000 dying later. Activists claim the toll is much higher, with victims still suffering from the side effects of the poisoning.

“Given Pithampur’s history of pollution, residents’ fears are valid,” said Mr Jayaraman.

Officials said they are only “dealing with the waste as specified by the court’s directive”.

But the reality of Bhopal has deepened the mistrust among the people of Pithampur, who are now prepared to take to the streets again to oppose the waste disposal.

Vegetable vendor Shivnarayan Dasana said the issue goes beyond the waste itself.

“It’s about survival – ours and our children’s,” he said.
