A biodegradable plastic that uses nanotechnology to efficiently catalyze the synthesis of CO2 has been successfully developed by the Guangzhou Institute of Chemistry, Chinese Academy of Sciences. To make the project industrialized as soon as possible, Guangzhou Guangzhong Enterprise Group plans to invest 30 million yuan to participate in the construction of a new 3,000 tons/year degradable plastics production line. On June 5, the signing ceremony of the project industrialization test cooperation was held in Guangzhou.
The biodegradable plastics produced by the polymerization of CO2 and propylene oxide can replace the fast-food packaging containers widely used in the market, which not only solves the environmental problems caused by CO2, but also avoids the "white pollution" caused by the use of plastic packaging. ". Although as early as 1969, Japan had an annual production capacity of 3,000 to 4,000 tons of CO2 polymer, and South Korea is now also planning to build a production line with an annual output of 3,000 tons. However, due to the high cost and the fact that the properties of the resulting plastics need to be improved, manufacturing plastics with CO2 is still in a semi-trial stage in the world and it is difficult to carry out large-scale industrial development.
Dr. Meng Yuezhong of Guangzhou Institute of Chemistry and others have been working on the research of "efficiently catalyzing CO2 synthesis of biodegradable plastics by nanotechnology" for several years. The principle is that CO2 and propylene oxide are copolymerized under the action of nano-supported catalysts at a certain temperature. And under pressure, to produce a fully degradable plastic - polycarbonate. At present, the project has achieved a major breakthrough. Each gram of catalyst in the laboratory can catalyze 120-140 grams of CO2, and the content of CO2 per ton of new plastic reaches 42%. This makes the CO2 extracted from the exhaust gas available for comprehensive utilization and can be scientifically reasonable. Industry chain. The plastics produced by this technology can be produced by common processes and can be processed into beverage bottles, fast food lunch boxes, agricultural films, etc. The project has reached the international advanced level.
According to the relevant person in charge of the Guangzhong Enterprise Group, the pilot test of this project can be completed quickly, and industrialization can be implemented after a detailed industrialization plan is formulated. Due to the high efficiency of this plastic synthesis and reduced costs, it is expected to enter the market at a price of 20,000 yuan/ton, which is much lower than the current market price of 35,000 yuan/ton for biodegradable plastics, and it is highly competitive. The extensive use of its strengths in the production of petrochemical machinery and equipment and the strength of integrated equipment research and development are complementary to the advantages formed by Guangzhou Chemical Industry, which is conducive to accelerating the process of industrialization of this achievement.
