Abstract
Most of the traditional tanning processes do generate wastes. These impact the environment in various forms including residual water with harmful pollutants, non-degradable solids as well as hazardous emissions and unpleasant odours. The present study examines an easy alternative method to the traditional vegetable tanning process at an industrial level to minimize pollutants. The new method is based on tanning eliminating common salt and significant reduction in water input. The advantages from the environmental point of view for the new method are substantial. There is 75% reduction in water input, 25% energy consumption reduction and 100% reduction in chloride discharge when the new method is adopted. The properties of leathers produced by the new process have comparable physical, chemical and organoleptic properties.
