A Kolkata company turns scrap leather into fertiliser

A factory in Kolkata uses scrap leather to make useful nitrogenous fertiliser.

Workers in the factory extract wet blue leather and recover a solid collagenic material containing high nitrogen levels, which can be used for the production of nitrogenous fertiliser. India’s import of nitrogenous fertiliser “urea” has been rising as farmers are demanding more to boost yields of staples such as rice and wheat, says Reuters.
