A Conventional technique of bovine hide preservation requires approximately 40-50% sodium chloride or table salt on raw hide weight or 95% saturated brine in case of wet salting. This salt resides in wastewater after the soaking process and generates a huge environmental pollution in the form of total dissolved solids (TDS) and chloride (Cl-) during leather processing. The current research has developed an antiseptic based hide curing formulation using 45% saturated brine solution which reduces 50% salt usage in compare to the traditional method. For hide preservation, it is essential to arrest microbial attack on hide as the main constituent of raw hide is protein which is very susceptible for bacterial degradation. The newly developed formulations have been found more effective in limiting microbial growth on cured hide than the conventional method preserving the bovine hide for more than 30 days. In-process analysis of cured hides during storage period reveals the compatibility of the alternative curing process. Post-leather analysis e.g. grain pattern, scanning electron microscopic images, mechanical properties and organoleptic evaluation reveal that the crust leather produced from alternatively cured hides are comparable to the control obtained from traditionally preserved hide. The efficacy of the alternative system is also assessed by monitoring the environmental impacts caused by the leather processing effluents on the basis of TDS and chloride content, total solids (TS), total aerobic bacterial counts in soaking liquor, Bio-Chemical oxygen demand (BOD) and Chemical oxygen demand (COD). The environmental advantages of the alternative hide curing method are determined particularly by 50% reduction of TDS and chloride content. Therefore, this new development will not only preserve hide through better protection from microorganisms but also offer improved conservation of the environment.
