Leather making, leads to creation of solid wastes like fine leather particles, residues from chemical discharges and large pieces of leather cuttings, trimmings and gross shavings, fleshing residues, solid hair debris and remnants of paper bags. The re-use or safe disposal of solid waste and sludge generated by tanneries is a big challenge
Tannery solid waste constitutes about 50-60% of fleshing, hair and other organic matter; 35-40% is chrome shavings and splits. The solid waste is then dumped at municipal landfill garbage sites causing serious public health and environmental hazards. The solid waste from the tanneries contains flesh, hair, chrome shavings, splits and other organic matter. At present, the common practices among tanneries is to dispose of the solid waste to landfills or dump them in empty fields. A large amount of the waste generated by tanneries is also discharged in natural water bodies without any treatment. This not only causes environmental hazards but is also a great risk to the public health.
