Paper Title
Short-Term Preservation of Hide/Skin as an Approach to Greener Process
Abstract
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.
