Short-Term Preservation of Hide/Skin as an Approach to Greener Process

The wet salting method, which is mostly used for hide or skin preservation requires approximately 40-50% of sodium chloride on raw hide/skin weight. All this salt falls into wastewater during soaking process and significantly increases pollution of the environment. Treatment of hide by sprinkling of dry mixture containing 5% of sodium chloride and 1% of sodium hexafluorosilicate(percentage are based on raw hide/skin mass)allows storage of the hide without putrefaction symptoms during 14 days when the storage temperature is 22±2oC. Leather produced from short-term preserved hide is not lower in quality comparing with leather produced from conventionally preserved by salting hide.
