The Department of Environment (DoE) here yesterday sued three more ship-breaking yards for polluting environment and not responding to its notices of clearance.
With this, seven ship-breaking yards have been sued within two weeks.
The DoE investigator Saiful Ashrab filed the cases with Sitakunda Police Station and the Environment Court.
The yards are Rahman Ship Yard and Mahin Enterprise (Ship-yard) at Modhyam Sonaichhari and Ambia Ship-breakers Private Limited at Madam Bibirhat in Sitakunda upazila.
The DoE investigator in the cases alleged that the authorities of the ship-breaking yards didn't respond to the repeated DoE notices that asked them to collect environmental clearance after ensuring protective measures against pollution.
The yards have been developed without environmental clearance or required protective measures and facilities for removing liquid and solid hazardous waste during cleaning and dismantling the ships, Saiful also alleged in the cases.
Saiful told The Daily Star that the cases have been filed against nine high officials of the yards, including their owners and managing directors.
