In recent years, with the wide use of bio-based leather, there has been a continuous renewal of cactus leather products, mushroom leather products, apple leather products, corn leather products etc. We are also confronted with the recycling issue of bio-based leather, and the recycling technology of bio-based leather has attracted much attention in the field of sustainable development. Recycling technology is mainly dedicated to reducing resource waste, lowering environmental pollution and enhancing the reuse rate of materials. The following are some common plant leather recycling techniques:
1.Plant based vegan leather - mechanical recycling method
Mechanical recycling is the most common way to recover bio-based leather, which usually involves physical crushing, cutting, and grinding of waste bio-based leather to transform it into new raw materials.
2. Bio-based leather - chemical recycling method
Common chemical recycling methods include enzymatic hydrolysis, acid-base treatment, etc. By degrading cellulose, protein and other components in leather, they can be transformed into reusable materials or chemicals. The advantage of this method is that it can achieve efficient recycling, but it may face high costs and potential environmental impacts.
3. Vegetable leather - pyrolysis recovery method
Pyrolysis recovery technology utilizes high-temperature and oxygen-free conditions to carry out pyrolysis reactions, converting waste bio-based leather into gaseous, liquid or solid products. The residue after pyrolysis can be used as fuel or as other industrial raw materials.
4. Leather vegan- Biodegradable method
Some bio-based leathers have natural biodegradable properties and can be decomposed by microorganisms under appropriate conditions. By taking advantage of this characteristic, waste leather can be treated through natural degradation, converting it into harmless substances.
