Pollution control board issues closure order to Deepak Nitrite's unit in Hyderabad

Deepak Nitrite Ltd (DNL), the Vadodara-based manufacturer of organic, inorganic and fine chemicals, has received an order from the Telangana State Pollution Control Board (TSPCB) for closure of one of its three manufacturing units situated at Hyderabad.

Deepak Nitrite manufactures DASDA (diamino stilbene disulfonic acid), a chemical used in the manufacturing of optical brightening agents (OBA), at its Hyderabad facility and the unit, for which order has been received, is a processing unit. The company’s DASDA production will be affected due to the TSPCB’s order.

The company said that it is taking all the necessary effective steps to correct the anomalies pointed out by the TSPCB authorities in the manufacturing system in the said unit at Hyderabad facility. “Very best efforts are being put to get the closure notice revoked within a week or so. There will not be any major impact on service to DASDA customers. The week long interruption in production will not have any major impact on the optical brightening agents production also, as adequate inventories are available,” said Deepak Nitrite in a BSE filing yesterday.
