“This is the second time that the biomedical waste is being dumped in the same location. After frequent complaints to TNPCB, they cleared it. But it has been dumped yet again, and is lying there for a week. In the recent case, there is a bill along with waste but the officials are yet to inspect the place. The contractors, without taking the medical waste to the incinerators, are dumping them in empty plots and burning it overnight,” said Pughazhvendan V, an activist.
