China's plastic processing industry strives to "plastic" a new pattern of green and high-quality development

Professor Wen Zongguo of the School of Environment, Tsinghua University, director of the Circular Economy Industry Research Center, the team has studied plastic waste management and other issues for many years and achieved results.

"Plastic waste management is one of the important environmental issues facing the world at present, clarifying the metabolic mechanism of plastic packaging and identifying alternative paths for material recycling is a basic scientific issue to promote green and low-carbon packaging and control environmental leakage rate." Wen Zongguo said that for more than 10 subdivided packaging materials, the establishment of localized environmental impact scientific data to support the ecological design of green and low-carbon packaging; More than 10,000 empirical tests have been carried out to accurately characterize the rule of urban 500 meters grid waste; The application of high-definition photography and spectral image recognition algorithms, the development of plastic packaging waste intelligent sorting technology...... Small takeaway packaging waste, in this way, the study is clear, and the waste packaging in life has become a research topic of great research value and a solution is given.

All sectors of society from different levels in the endeavour to solve the problem of development, as the whole industry how to find the right direction, comprehensive improvement? The Outline provides a timetable, a road map and binding targets:

The plastic processing industry should fully implement the green development strategy of the industry, seize new opportunities, respond to new challenges, and adhere to ecological priority and green development. It is necessary to promote green upgrading, promote energy saving and consumption reduction, reduce environmental pollution, strengthen green design, promote recycling, scientifically promote the application of degradable plastics, and pay attention to green regulations. To promote the construction of green circular economy parks and other aspects of nine work, to achieve steady improvement in energy efficiency, continuous decline in carbon emission intensity, industrial green development energy level, plastic processing industry energy efficiency steadily improved. It is planned that by 2025, the carbon dioxide emissions per unit industrial added value of the plastic processing industry will be reduced by 18%, and the energy consumption per unit added value of the enterprises will be reduced by 13.5%.

How to achieve goals with high quality? After a lot of in-depth research, Zhang Chonghe put forward four suggestions:

First of all, to overcome key technologies to promote the transformation and development of plastics industry. Standard international advanced, keep up with the forefront of science and technology, in the new energy functional application of membrane materials, solvo-free environmental protection materials, waste plastic high-value utilization, high-function engineering plastics and other key areas, organize technical research, and strive for international leadership. It is necessary to vigorously adopt recycling technology, promote the ecological construction of plastic processing, concentrate the strength of the industry, and carry out innovative research on plastic functionalization, lightweight, precision, ecological and intelligent.

Secondly, accelerate the transformation of technological achievements and promote the comprehensive transformation and development of the plastics industry. It is necessary to give full play to the leading role of experts, academicians and universities in innovation, build an integrated platform for industry-university-research and application, promote integrated innovation of industry-university-research and application, and form a collaborative system of R&D and transformation among enterprises, universities and institutes. It is necessary to build a comprehensive service platform, smooth channels for the application of achievements, integrate the innovation chain, industrial chain, human resources chain, and capital chain, and promote the application of scientific and technological achievements in a holistic manner.

In addition, we will strengthen low-carbon ecological manufacturing and promote the green transformation of the plastic industry. It is necessary to speed up the construction of a waste recycling system, promote the research and development and application of advanced technologies for energy saving and carbon reduction, strengthen the use of new green functional materials, strengthen the recycling and utilization of renewable resources, promote new technologies and products that can be recycled, easily recycled and degradable, reduce application costs, and increase the supply of green products. It is necessary to promote the upgrading of green chemical plants, accelerate the research and development of low-carbon product technology, strengthen the research of ecological degradation mechanism, build a carbon footprint accounting system for the whole life cycle of plastics, and cultivate new business forms and models of standardized recycling and recycling. To promote the green transformation and development of plastic processing industry with low-carbon and ecological technology.
