Advancements in Tannery Waste Management

Summary:
The discharge of solid waste and wastewater containing chromium is the main environmental problem. Chromium is a highly toxic compound and the dumping of chromium containing material is in most countries restricted to a few special dumping grounds. Reduction of chromium discharge is therefore essential. Emissions into the air are primarily related to energy use, but also the use of organic solvents and dyes causes emissions into the air. It is the case that only 50% of raw hides and skins actually make a successful transition to leather and, in many instances, all the rest go to waste. Research projects have aimed at reducing waste and creating more of a closed loop. This would involve…
