Why recycle waste leather?
With the improvement of people’s living standards, the scope of use of leather products is also expanding. Every year, because of waste leather residue produced in the production process and because of breakage, old style and other reasons, various kinds of leather are discarded in astonishing amounts.

Facing this dilemma, studies have found that people can use waste leather to extract Remy A, recycled leather and feed collagen powder. Although we are very unfamiliar with these materials made from recycled leather, the materials made from recycled leather can save a lot of resources for life and growth.
Leather is the material we get from animal skin. The most common leather we can find in the market is cowhide, pig leather and sheep leather. Leather is widely used in our daily life because it is characterized by durability and flexibility. We can see products made of leather everywhere.
