Leather

Leather tanning involves the use of many chemicals. Hence the effluent from the tanneries is highly toxic for the environment. We, at Sheong Shi Tannery, first treat the effluent in our in-house pre-treatment plant, segregating the suspended particles and the dissolved particles from the effluent and then sending them onwards for further treatment at the Common Effluent Treatment Plant run by the Calcutta Leather Tanners’ Association.

 

 

The design of the tannery building has been done in the shape of a “U”. This has been done to increase the surface area of the building thus enabling better ventilation. And presence of large windows allows ample sunlight to come and light up the work-place.
