What is the Eco-leather?

In the strict verbal sense of the definition, the term "eco-leather" has no formal meaning. Eco-leather is basically the attempt to produce leather with a minimal environmental impact and to give it an Eco-friendly label. 

Eco Leather

The manufacture of leather does have an environmental impact, in as much as in the manufacturing process, not all the inputs end up in the leather. Also when leather is disposed of the product becomes a waste material.  What seems to have happened is that the gauge of a leather's "eco-ness" is measured by the absence of certain restricted chemicals, such as banned azo dyes, PCP, chrome VI, formaldehyde and an increasing list specified by brands; or the method of tonnage rather than any consideration of the real environmental impact.
