New technology of carbon dioxide to produce environmental friendly plastics

a key technology (cutting the minutes and operating in the opposite direction of the experiment) of Guangzhou Institute of chemistry, Chinese Academy of Sciences has achieved continuous breakthroughs

it was learned from Guangzhou Institute of chemistry, Chinese Academy of Sciences that lead researcher Meng Yuezhong made a continuous breakthrough in the development of high-efficiency catalysts, the key technology of fixing carbon dioxide into fully degradable plastics, by dividing the surface product of material indentation pits by the load value

carbon dioxide plastic technology has experienced decades of development. Due to the high cost and its performance to be further improved, relevant research and development has been actively carried out. Meng Yue's success lies in the use of low-cost and highly active rare earth composite catalysts and materials supported by nano materials to quickly fix carbon dioxide, while improving the high content of carbon dioxide in polymers. The catalytic efficiency and high content of carbon dioxide and other indicators achieved by the nano zinc carboxylate synthesized by him under the support of the "hundred people plan" of the Chinese Academy of sciences have been the highest values reported in all literature in the world, and the catalyst can be recycled. The carbon dioxide polymer is buried in the sludge, and it can be degraded by 4% every three months (1. The degree of degradation of the new catalyst preparation and utilization technology reaches 17%, and the plastic can be broken)

it is reported that this polymer has excellent characteristics such as low temperature resistance (- 80 ℃), high barrier, transparency and degradability, so it can be used in the production of low-temperature fresh-keeping films, gum base materials, and disposable packaging materials for food and medicine; By adding 5-10% carbon dioxide polymer into the base material, a disposable degradable fast food box with high temperature resistance, oil resistance and mold resistance can be obtained

the successful industrialization of the project will bring great economic and social benefits. At present, the annual demand for fully degradable polymers abroad has formed a huge market of more than ten million tons, and more than one million tons in China. This new technology can enable a 1million ton production line to solve the carbon dioxide emission problem of 30 Guangzhou petrochemical plants, and the "white pollution" caused by ordinary plastics can also be avoided

according to Professor Meng, the project has the conditions to transition from laboratory test to industrialized pilot test. In the next three years, relevant achievements will help enterprises establish production lines with an annual output of 1000 tons of carbon dioxide polymers, and gradually provide technical data for 10000 tons of production, so as to meet the cost standard of industrialization and sustainability
