Utilization of Tannery Flesh Waste for Production of Sustainable Leather Coating Substance

The leather tanning industry is one of the most polluting industries because it generates a gigantic amount solid, liquid, and gaseous waste. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing clouds dust, keratin wastes. Flesh generated from tanneries during processing, especially in sheep liming. These skin-flesh contain significant fat content, which being wasted dumped open areas or at dumping sites. As result, this flesh waste disposal has created major environmental problem. This research aims to extract sustainable functional substance that can be used for imparting aesthetic properties (polishing) product. In research, calculated was washed, de-limed, cut into small pieces solvent extraction using Soxhlet apparatus hexane as solvent. Chemical analysis extracted showed saponification value ranging 189 192. values indicate triglyceride, lubricant. However, when applied products like shoes, surface an increase their (lustre, gloss) giving excellent polishing results. acid value, melting point, density, viscosity stability making promising impart functionality usage material. could replace synthetic, functional, materials overcoming challenges posed by process.
