The tanning industry is one of the pillar industries of the country and at the same time one of the more polluting industries. Due to the complexity of the raw materials used and the complexity of the process, the by-products produced by the tanning industry are also complex and varied. And because the raw materials are mostly petroleum-based substances, the exhaust gas generated by the complex composition, volatility, and has a strong odour.
