Combination tanning based on Tara-Sodium metasilicate a new tanning

Based on the results and conclusions of this study, As indicated from the shrinkage temperature and physical measurements results it should be clear that leather can be made from the combination tanning system needs pH control during silica solutin preparation. There is scope to improve the strength properties of leathers tanned with tara-silica combination tanning system. careful pH controll is required for each parameter during silica-tara cobination tanning. To see the practical applicability of an alternative system of tanning, Awareness creation for leather industries and societies should be done so as to use sodium metasilicate and tara combination to reduce environmental impact due to chromium.Substitution of conventional tanning agent by sodium metasilicate and tara combination is one option by which we can remove chromium discharge from tanning effluent. Other tanning agents like plant extracts and minerals can be researched as a partial or whole substitute for Basic chromium sulphate that could efficiently tann the pelt and reduces the chromium and TDS discharge from tanning effluent.
