1. Chemical materials
Waste grease is made into leather fatliquor and degreasing agent; cow hair can be directly used as a protein-based finishing agent after controlled hydrolysis, with good brightness and resistance to polishing. It can also be used directly as an anti-adhesive agent for embossed ironing. Ox hair can be used as a modified material for cross-linking and grafting of polymer materials after controlled hydrolysis. Cow hair can also be made into collagen-modified coating agents, such as acrylic, polyurethane and butadiene.
2. Other fields
Blue leather fiber can be made into regenerated leather and non-woven fabrics; leather edges are hydrolyzed and spun into hygroscopic collagen blended fabrics; hair is directly used into wool spinning, Carpet making, felt making, brush and brush making. Leather solid waste can also be made into pet toys and chews, as well as high-grade protein and refined collagen. Leather solid waste is mixed and polymerized with synthetic polymer materials to make degradable plastics, and combined with fiber materials to make degradable lunch boxes, etc.

Notes on leather and scraps:
1. All genuine leather has the smell of leather; artificial leather is highly irritating. The smell of plastic.
2. The leather surface has no pores, which is an important feature for identifying the authenticity of leather.
3. If the corners are cut off and burned, there will be a smell, but it is not the smell of burnt hair.
