| Abstract |
The first industrial revolution of polymer materials, which ended in the 1970s, created the polymer world. The ongoing second industrial revolution may bring the polymer material industry into the "circular economy" mode, which is a rare opportunity for China's polymer science and industry to achieve leap-forward development. This article summarized the research progress of our team in the chemical and physical recycling of waste polymer materials, including high-temperature pyrolysis of waste polymer materials to olefins, straw and other waste biomass pyrolysis to hydrogen-rich synthesis gas, upcycling of carbon fiber reinforced composite, and a new method of high-temperature solid-state polymer grafting. The advantageous application fields and development prospects were also discussed. Finally, a new polymer "circular economy" development model was proposed. In the model, waste polymer materials and waste plastic oil will become feedstock for ethylene industry. The products obtained by cracking the feedstock can be separated into different chemicals, among which, ethylene, propylene etc. can be polymerized into brand-new polymers by existing petrochemical technology and equipment. Meanwhile, biomass materials, such as plant oil and straw, can be supplementary to this circular process as feedstock. This new model can not only help the polymer industry get rid of the reliance on fossil materials, but also solve both the "white" and "green" problems of polymers at the same time. [GRAPHICS] |
