Biodegradable Vegan Leather
Najina Persimmon Leather
Limitations and Issues of Conventional Leather
Why do we need a new leather?
Issues of Natural Leather
Environmental Pollution & Animal Sacrifice
Production Process Issues
- ・Generation of massive wastewater and by-products
- ・Use of various hazardous substances including trivalent chromium
- ・Inevitable animal sacrifice (criticized by animal welfare organizations)
Disposal Issues
- ・Emission of hazardous substances during incineration → Air pollution
- ・Soil contamination during landfill
- ・Environmental hormone risks (phthalate plasticizers, organotin)
Issues of Synthetic Leather (PU/PVC)
Non-biodegradable & Chemical Substances
Environmental Destruction
- ・100% non-biodegradable
- ・Generation of microplastics
- ・Emission of toxic gases during incineration
Harmfulness
- ・Contains phthalate plasticizers
- ・Detection of organotin compounds
- ・Potential human health hazards
Issues of Conventional Vegan Leather
Limitations of Pineapple, Mushroom, Cactus, and Grape Leather
Non-biodegradable
- ・Plant-based fibers + PU coating
- ・Plant-based protein + PU mixed coating
- ・Use of chemical coating agents and binders
- → Eventually 100% non-biodegradable
High Cost
- ・Complex manufacturing process
- ・Expensive raw materials and technology
Unresolved Environmental Issues
- ・Difficult to recycle
- ・Greater environmental burden during disposal

Product Cross-section Comparison
Coating Layer Similar to Natural Leather
Najina products can adjust the total thickness according to fabric selection and surface coating layer thickness.
Natural Leather
- Resin layer thickness less than 0.15mm, too thin, resulting in reduced durability
Cause of
cracking or
peeling over time
Synthetic Leather
- Non-woven fabric + synthetic resin coating
- Resin layer thickness over half
Persimmon Leather
- Base fabric structure maintained
- Persimmon resin penetrates into fabric interior
- Durability and flexibility
