Preparation of Regenerated Leather from Tannery Solid Wastes: Geno-Corium

Regenerated Leather Geno-Corium from Tannery Solid Wastes

• The solid waste such as chrome shavings, or chrome-free shaving waste, or ground crust or finished leather trimming waste, or buffing dust is thermos-chemically (alkaline) hydrolyzed, followed by enzyme (protease) treatment optionally.
• The composition for calendaring is prepared mixing the hydrolyzed solid wastes with cross-linkers, acrylic syntan, dye and synthetic fatliquor and plasticizer.
• Calendaring using the composition prepared is done over a coat of synthetic film formed on a release paper.
• Finally, reinforcement with synthetic or natural fabric is done by pasting the fabric over the film, to make the Regenerated Leather Geno-Corium.

• It is a sustainable solution for utilizing solid wastes from the leather industry and the used/discarded leather products as well.
• This novel process of making regenerated leather not only provides a fool-proof solution to an environmental problem but enables the industry to secure significant financial returns.
• Geno-corium leather is suitable for all the applications as that of leather. Suitable for manufacturing of shoes, life-style products and garments.
• Tested for physical properties & found to meet the requirements.
• This process technology is not associated with generation of wastewater or solid waste
