Building a PPC production plant enables manufacturing fully biodegradable eco-plastic using CO₂ and propylene oxide as raw materials, which reduces greenhouse gas emissions and dependence on fossil fuels. Compared with PLA, PPC boasts higher strength, superior flexibility and lower production cost; it can supply low-molecular polyols to replace petroleum-based products, while high-molecular PPC can be made into barrier films and injection molding materials for packaging and agricultural sectors.
