CHENNAI:
Leather industry has undertaken research to develop technologies that would value-add to quality of leather and also contribute in reducing environment pollution.
The Central Leather Research Institute (CLRI) is working on the use of enzymes to help reduce use of chemicals.
Advanced Enzyme Technologies Ltd (AETL), a leading manufacturer of enzymes and pro-biotics has developed enzymes that can partially replace some chemicals used in processing of hides and skin to produce better quality leather in terms of grain structure.
“Our enzymatic process does not degrade hair, so the hair can be recovered from the water. Water can be recycled and reused. They are very specific to the substrate and are not as chemicals which act harshly irrespective of the substrate. Enzymes will work specifically and give better grain structure,” according to Managing Director C L Rathi.
The company has received patent for the leather process and it is named “eco-friendly wet blue manufacturing,” he said.
Total replacement of chemicals presently is not possible, Rathi said.
“some chemicals or salts are necessary to bring about the necessary textural and other changes in hides. Enzymes will co-work with such chemicals to give improved effect,” he added.
Use of enzymes is advantageous in improving quality of leather and environment, moreover cost wise it would be similar to chemicals, he said.
