CLRI project converts salt from raw hides

05/05/2017
Scientists at India’s Central Leather Research Institute (CLRI) have discovered a way to break down the salt left over from tanning processes into saleable elements, according to local press.

The salt has been building up at common effluent treatment plants and is difficult to dispose of, causing environmental problems.

Although still at a trial stage, the CLRI said the process to separate the waste into sodium chloride and sodium sulphate has reached the required purity and a pilot project is being launched at a salt farm in Bhavnagar.
