“…Leather manufacture involves the following unit processes viz., soaking, liming, deliming, pickling, tanning, post-tanning, and finishing, where tanning is considered as one of the important process, 3 that protects the leather against environmental effects such as microbial degradation, heat, sweat, or moisture. 4 Vegetable tanning is the oldest tanning process in the leather sector, even though chrome tanning has gained prominence in leather manufacture ever since its discovery by Prof. Knap in 1858. 5 Today 90% of leather is manufactured using chrome tanning system mainly due to its high stability to wet heat with a shrinkage temperature of about 110 C, but the chrome tanning agent is under constant scrutiny due to low uptake of Cr(III) salts which is released in tannery effluent, and also exposure of Chromium bearing wastewater is harmful to human beings and animals, because of the biotoxicity of Cr(III) salts under certain ligand environment.…”
