Abstract

The tannery business is one of the essential areas in today’s global economy. However, on the other hand, this industry has its own peculiar culpability for huge pollution loads on the environment. The prime challenge is managing waste generated during the leather manufacturing process; thus, the tannery industry is becoming a growing concern. Recent technologies that use negative-valued garbage as a feedstock to generate energy or value-added products could be a game-changer in the current nonrenewable dependency. This review outlines different routes for converting tannery waste biomass into a gamut of marketable products and energy to pave the way for sustainable biorefinery development avenues. The primary organic resource is “collagen”—a natural protein present in the skin hides that can be transformed into different leather composites such as adhesives, adsorbents, and renewable fuels such as biogas. This review provides comprehensive information about circularizing the waste-to-wealth economy with futuristic perspectives and opportunities.
