| Abstract | Manufacturing of leather, leather goods, leather boards and fur produces numerous by-products, solid wastes, high amounts of
wastewater containing different loads of pollutants and emissions into the air. The uncontrolled release of tannery effluents to natural water bodies increases health risks for human beings and environmental pollution. Effluents from raw hide processing tanneries, which produce wetblue, crust leather or finished leather contain compounds of trivalent chromium (Cr) and sulphides in most cases.
