Carbon dioxide synthesis biodegradable plastic is expected to achieve industrialization

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. It was learned that on June 5, the signing ceremony for the cooperation of the project's industrialization experiment was held in Guangzhou.
It is reported that this kind of biodegradable plastic polymerized with 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 use of plastic packaging. White pollution". 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 high costs, the use of CO2 to manufacture plastics is still in a semi-trial stage in the world, making it 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 120g to 140g of CO2, and the content of CO2 per ton of new plastic reaches 42%. The CO2 gas extracted from exhaust gas can be comprehensively utilized and can be formed scientifically and rationally. Industry chain. The polyplastics produced by this technology can be produced by common processes, and can be processed into beverage bottles, fast food lunch boxes, and agricultural films. 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. Because of this high efficiency of plastics and reduced costs, it is expected to enter the market with 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 is extremely competitive. The extensive use of its own strengths and the strength of complete sets of equipment integration R & D, and complementary advantages formed by the Guangzhou Chemical Industry, will help speed up the process of industrialization of the results.
