Carbon footprint

Environmental effect

 

Leather produces a few environmental impact, most notably due to:

 

The carbon footprint of farm animals rearing

Use of chemical compounds inside the tanning technique (e.G., chromium, formic acid, mercury and solvents)

Air pollution because of the transformation system (hydrogen sulfide at some point of dehairing and ammonia in the course of deliming, solvent vapors)

 

 

 

One estimate of the carbon footprint of leather items is zero.51 kg of CO2 equal in step with £1 of output at 2010 retail charges, or zero.71 kg CO2eq consistent with £1 of output at 2010 industry costs.[9]

Water footprint

 

One ton of cover or skin usually produces 20 to 80 m3 of waste water, such as chromium stages of a hundred–400 mg/l, sulfide stages of 200–800 mg/l, high ranges of fats and different solid wastes, and excellent pathogen infection. Producers frequently add pesticides to defend hides for the duration of transport. With strong wastes representing up to 70% of the moist weight of the original hides, the tanning process represents a large pressure on water treatment installations.[10]
