What Are Biodegradable Materials?


Polylactic acid (PLA) is a biodegradable polymer material prepared from biomass material by high technology. PLA has excellent biodegradability. After being discarded, it can be completely degraded by microorganisms in the soil to generate CO2 and H2O without environmental pollution

PLA is made from corn, potato and other starch-based biomass or straw cellulose as raw materials, fermented to produce lactic acid, and further purified and polymerized to prepare high-purity PLA, which is environmentally friendly, non-toxic, antibacterial, flame retardant and good biocompatibility. It can be completely biodegradable under normal composting conditions. With the largest output, the widest application range, the highest cost performance and the closest to petro-based polyester in the world, PLA will account for 70-80% of the market share of biodegradable material.
