Extraction of elastin from tannery wastes: A cleaner technology for tannery waste management

During leather processing, most of the trimmed raw skins/hides are thrown as wastes which require solid waste management. In the present study, raw hide trimming wastes have been used as the source for extracting elastin. Elastin is extracted from raw trimming wastes through thermo-chemical treatment method using alkali pre-treatments. The physical characterization using differential scanning calorimetry showed the melting point at 104 °C....
