Characterization of Enzyme-Treated Eco-Friendly Iron Tanned Leather

Tanning is the process of converting putrescible raw hides and skins into non-putrescible leather. The most common chrome tanning process is not eco-friendly at all. But the increasing demand for leather leads us to find an eco-friendly tanning process. Therefore, the elimination of pollution due to the use of chrome and dyeing material is a matter of concern here. The primary objectives of this study are the reduction of pollution from using chrome and dyeing materials in the tanning process and their impacts on human life as well as the environment. In this study, different types of iron salts, combinations of different iron salts, and iron with chromium salts are used for tanning and no dyeing material is used to give color to the leather. On the other hand, various types of enzymes were applied for the completion of the beamhouse operation. Finally, the physical and thermal properties of various tanned leather were summarized to propagate an eco-friendly new tanning method.
