Sinopec Tsinghua University released a research report on degradable plastics

On September 26, the "Research Report on Environmental Impact Assessment and Policy Support of Degradable Plastics" jointly researched by Sinopec and Tsinghua University was officially released
.
The "Report" draws the material metabolism map of degradable plastics in China, proposes for the first time that the degradable plastics with degradability as the core are compared with the traditional plastic evaluation index system, and analyzes the feasible use path
of degradable plastics from multiple dimensions of social economy.

The report answers the urgent problems in the field of degradable plastics
.
For example, whether degradable plastics have better environment-friendly characteristics than traditional plastics, whether the alternative of degradable plastics to traditional plastics can achieve the role of plastic environmental leakage control, and what are the use scenarios of degradable plastics
.

The "Report" believes that there are structural contradictions in the current use of degradable plastic products, and it is necessary to face up to the application scenarios of degradable materials and the effective layout
of production capacity.
It is necessary to focus on the application of key scenarios, reduce the high-cost layout of degradable materials, the abuse of application scenarios and the development of low effects, and focus the use of degradable plastic products on the field of
direct environmental leakage.

The "Report" proposes that in the existing terminal treatment facilities, degradable plastics and traditional plastics have little difference in environmental impact, and it is necessary to clarify the whitelist of degradable plastic application scenarios, and the use of plastic products with direct environmental leakage as the premise for
the formulation and introduction of degradable plastic alternatives in various places.

The "Report" suggests that based on the actual operating time of China's industrial composting and anaerobic fermentation processes, the degradation time evaluation index of degradable plastics should be corrected, and the degradation time of industrial compost should be adjusted to 30 days, and the degradation limit time of anaerobic fermentation should be adjusted to 40 days
.
At the same time, from the perspective of the application of degradable plastics is to solve the problem of environmental leakage, if there are degradable environmental conditions, the substitution of
degradable plastics can be given priority in those areas where the film residue film recycling industry is not perfect.
