It has flagged ‘red’ 24 of these establishments as those are dangerously close to the world heritage site and polluting the soil, water and air of the world’s largest mangrove forest.
The levels of harms caused by the other organisations are also increasing heavily, the DoE says in a report it made following a High Court order.
According to the report, 92 of the 190 factories are situated in Khulna, 78 in Bagerhat and 20 in Satkhira. Out of these, 36 are closed now.
It had also asked the DoE to submit a report on the plants in these areas.
The bench of Justice Moyeenul Islam Chowdhury and Justice Md Ashraful Kamal heard the petition.
It also issued a rule asking the authorities why the new factories will not be removed, and the order for their approvals will not be deemed illegal under a 1999 government order that banned factories within 10km.
Mohammad Zakir Hossain stood for the petitioner, Sheikh Faridul Islam, chairman of Save the Sundarbans Foundation.
The deputy attorney general said the report would be presented at the hearing of the rule on May 9.
Speaking about the report, petitioner Zakir told bdnews24.com, “The 24 industrial organisations flagged red cannot remain within 10 kilometres of the Sundarbans in any way".
He said the Bangladesh Environment Conservation Act prohibits the existence of such structures within 10 kilometres of Ecologically Critical Areas or ECAs like the Sundarbans.
“The other factories’ impact on this area is increasing. The hearing on whether the court should order these factories to relocate will be held on May 9,” he said.
“But expert opinions will be needed for the hearing of the rule to find out how harmful these factories are,” he added.
