Tanning technology does not need water to help protect the environment

India's Central Research Institute of Skin (CLRI) has announced a breakthrough, tanning technology that does not need water in the process of skin treatment , in the hope of saving rivers from being polluted by wastewater. containing toxic chromates and sulphates mixed in more than 170 million liters of water every day.

CLRI, part of the Council for Scientific and Industrial Research (CSIR), has applied for the technology patent in 2014.

This technology helps save water and protect the environment.

Now, the institute has a "product" and a " tanning process" that does not need water and salt, thereby saving water and protecting the environment.

CSIR-CLRI B. Chandrasekaran director said, about 50 liters of water are needed to treat 1kg of animal skin.

This is the amount of water needed to wash the amount of salt used by the tanners in the early stages to preserve the skin and the amount of waste water after treatment is toxic.

CLRI's patented technology uses conventional drum tanning instead of using lime water with additives.

This saves water and reduces solid waste from lime and other chemicals.

Chandrasekaran said this technology helps reduce about 90-95% of wastewater.

Currently many tanning companies around the world are approaching CLRI to buy the technology.
