According to statistics, as much as 24 billion tons of carbon dioxide are generated every year due to the burning of fossil energy, about 15 billion tons are absorbed by plants during photosynthesis, and the remaining 9 billion tons remain in the atmosphere forever. In order to turn resource-rich carbon dioxide into waste, carbon dioxide copolymer-based biodegradable plastics have become a hot spot for development.
Wang Xianhong, a researcher at the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, told the China Science Daily that the main raw materials of carbon dioxide-based plastics are carbon dioxide, propylene oxide, and propylene. Among them, carbon dioxide is used in large quantities, with a mass percentage of about 40%.
In addition to the significance of resource recycling, environmental effects of carbon dioxide-based plastics make its advantages clear, Wang Xianhong said that because carbon dioxide-based plastics are aliphatic polyesters, they have 100% biodegradability and avoid secondary pollution of the environment by traditional plastic products.
