Owners of zip, button and accessories dyeing/bleaching units observed fast here on Wednesday to condemn the sealing of many such units by Tamil Nadu Pollution Control Board (TNPCB) over the past few months on the charges of creating pollution.
The agitators were of the view that closure/sealing of about 150 zip, button and accessories dyeing units by TNPCB could not be justified as sludge generation was very minimal when compared to the normal dyeing operations carried out by the fabric dyers.
