RESEARCH FIELD
Polymer materials exhibit outstanding comprehensive properties and find extensive applications across various fields of the national economy. However, their non-standardized treatment and lack of effective recycling technology result in a low recycling rate of waste polymer materials, serious environmental pollution, and great waste of resources.
In view of the world challenges faced by environmentally friendly polymers and recycling under the background of carbon peaking and carbon neutrality, the Research Center for Green and Low-carbon Processing and Resource Utilization of Polymer Materials promotes the green and low-carbon development of the polymer industry from the whole chain of source substitution, green and low-carbon processing, and waste recycling. The center establishes high-value utilization of biomass materials in solid phase and green and low-carbon manufacturing technologies for polymer materials, develops key technologies and equipment for green and efficient recycling of waste plastics, and helps realize the national “carbon peaking and carbon neutrality” goals, providing the world’s leading Chinese solutions for global plastic pollution control.
Led by Professor Wang Qi, an academician of the Chinese Academy of Engineering, the research team brings together outstanding talents such as the Yangtze River Scholar Distinguished Professors, leading talents in Scientific and Technological Innovation, Young Top-notch Talents of the National Ten Thousand Talent Plan, and Academic and Technical Leaders in Sichuan Province. It is a team with a reasonable structure and strong scientific research capabilities. The research team has achieved significant innovative results in the recycling of waste polymer materials and advanced processing of environmentally friendly polymer materials. These achievements provide crucial support for resource recycling, resource conservation, energy efficiency, and contribute significantly to carbon neutrality efforts.
In response to key challenges such as low resource utilization level of waste polymer materials and biomass materials, and lack of cost-effective and environmentally friendly polymer materials, the center plans to focus on conducting key technologies including high-value and efficient resource utilization of waste plastics, green and low-carbon manufacturing of environmentally friendly polyvinyl alcohol packaging products, and high-value utilization of cellulose-based biomass materials in the solid phase. The center aims to promote industrial application, build a recycling and utilization system for waste plastics, develop a green, low-carbon, and circular economy, enhance the prevention and control of waste plastic pollution, and help achieve China’s “carbon peaking and carbon neutrality” goals. Specifically, the main research directions of the center are as follows:
1
To address the problems of difficult secondary processing of cross-linked waste plastics and difficult separation and classification of co-mingled composite waste plastics, the center develops environmentally friendly waste plastics recycling technologies, combining advanced plastic processing technologies such as rotary extrusion, solid-state stretching, dynamic molding, and interface crosslinking to prepare high-value and high-quality recycled special materials and products. The center optimizes the structure of solid-phase shear milling processing equipment, improves production efficiency and capacity, and establishes the world’s leading key equipment for the large-scale processing of mixed waste plastics that is efficient, clean, and easy to implement locally.
2
The center establishes and develops green and low-carbon thermoplastic processing technology of polyvinyl alcohol with high performance, low cost, and environmental friendliness. This technology enables the co-mingled compounding and molding processing with biodegradable plastics and biomass materials, and helps produce new packaging products such as polyvinyl alcohol-based films and foams with high performance, multi-function, and environmental friendliness on a large scale. Additionally, the center achieves the safe landfill and environmentally friendly evaluation of polyvinyl alcohol-based packaging materials, and replaces existing non-degradable disposable plastic packaging products on a large scale.
3
The center develops new principles and technologies for solid-phase high-value utilization of cellulose, realizes microfibrillation and solid-phase utilization through shear milling and steam explosion, prepares high-performance packaging materials and products, and researches microfibrillation behaviors and multi-level structural regulation mechanisms. Moreover, the center achieves the co-mingled compounding of waste plastics and agricultural and forestry wastes such as wood powder, rice husks, and straw, as well as the regulation of phase domain structure, prepares high-value wood plastic products, and realizes high-value utilization of cellulose and lignin.
