Powering a Greener Future
The conventional leather tanning technology is highly polluting as it produces large amounts of organic and chemical pollutants. Wastes generated by tanneries pose a major challenge to the environment. Anaerobic digestion of tannery wastes is an attractive method to recover energy from tannery wastes. According to conservative estimates, more than 600,000 tons per year of […]
Wastes originate from all stages of leather making process, such as fine leather particles, residues from various chemical discharges and reagents from different waste liquors comprising of large pieces of leather cuttings, trimmings and gross shavings, fleshing residues, solid hair debris and remnants of paper bags. Tanning refers to the process by which collagen fibers […]
Tanneries generate considerable quantities of sludge, shavings, trimmings, hair, buffing dusts and other general wastes and can consist of up to 70% of hide weight processed. Thermal conversion technologies by virtue of chemically reducing conditions, provides a viable alternative thermal treatment for tannery wastes, especially for chrome containing materials, and generates a chrome (III) containing […]
