The Ultimate Material for the New Age
-- Birth to Death of Polylactic Acid
1. The principle that biofabrication contributes to carbon neutrality
Develop biological industry, realize the utilization and transformation of renewable resources, change the "black gold economy" based on coal to the "green gold economy" based on living material processing, promote the development of agriculture by industrial means, replace the amount of oil and coal fossil resources, improve the atmospheric environment, achieve sustainable development, and become a model of circular economy.
2. Polylactic acid is fermented from corn, potato and other starch-based biomass or straw cellulose to lactic acid, which is further purified and polymerized to produce high-purity polylactic acid. It has environmental protection, non-toxic, antibacterial, difficult to burn and good biocompatibility, and can be completely biodegradable under normal composting conditions. It is considered as the main material to replace petroleum-based plastics (PE, PP, PVC, etc.) and petroleum-based chemical fiber (PET, PTT, PBT, etc.) in the future.
