[ Hot Focus on Chemical Machinery and Equipment Network ] On December 28, 2020, China’s total oil consumption control and policy research project held an online press conference and released a new report "China Plastics Environmental Footprint Assessment".
The report was written by the Beijing Institute of Petrochemical Technology.
It mainly analyzed the environmental impact of plastic products throughout the life cycle, and on this basis, put forward the goals, roadmaps, safeguards and expected benefits of plastic consumption reduction.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentThe report was written by the Beijing Institute of Petrochemical Technology.
It mainly analyzed the environmental impact of plastic products throughout the life cycle, and on this basis, put forward the goals, roadmaps, safeguards and expected benefits of plastic consumption reduction.
According to the report, if we continue to develop in the current inertial mode, by 2050, plastic production will consume 20% of oil, and the carbon emissions from production and use will account for about 15% of the total carbon budget (2 degrees Celsius scenario).
As an important plastic production and consumer country, my country has accelerated the production of primary form plastics since 1991.
As of 2019, the cumulative production of primary form plastics in the country has exceeded 1 billion tons.

The production and processing of a large number of plastic products will inevitably bring more waste plastics.
And what kind of bad impact plastic waste will have on the environment has become a social consensus.
From the perspective of environmental capacity, plastic has become "super waste".
How to further reduce the harm it brings has become a worldwide problem.

*As my country's ban on plastics has increased, "degradable" plastics have begun to be mentioned frequently.
However, degradability is not the same as 100% degradation.
Judging from the previously released " Guidelines for the Classification and Labeling of Degradable Plastic Products " (for trial implementation), the biodegradation rate has reached more than 90%.
We generally believe that this is a "fully" degradable plastic, but this type of fully degradable plastic is When compost, soil and other environmental conditions are degraded, a small part (ie less than 10%) of organic carbon contained in it will turn into biological dead bodies or mineralized inorganic salts.

It can be seen that degradable plastics are not the "*answer" to solve the pain points of plastic waste.
And facts have proved that "degradable" is not equivalent to low environmental impact.
In the report released this time, this point of view is also mentioned.
The essential carbon age of plastics, its position in the product chain, and the way of back-end treatment and disposal together determine the comprehensive environmental impact of its entire life cycle.
If the method of disposal is incineration, fossil-based degradable plastics are less environmentally friendly than non-degradable plastics.
Moreover, expanding the scale of waste incineration will not only harm public health, but will also increase financial burdens and waste of resources.

Moreover, expanding the scale of waste incineration will not only harm public health, but will also increase financial burdens and waste of resources.
Therefore, the importance of recycling plastic is more prominent.
According to the report, it is conservatively estimated that every 1 ton of waste plastics can replace 0.
67 tons of clean resin raw materials, thereby avoiding 1 ton of petroleum resource consumption and 1 ton of garbage incineration, and comprehensively reducing 5 tons of carbon dioxide.

The report believes that to promote the plastic economy from an open-loop linear model to a closed-loop circular model is a systematic change from concept, technology, management, production and consumption.
This puts forward the general idea of my country’s "plastic control" in the next 15 years: starting from the entire industrial chain from raw material production and processing to product sales, use and recycling, starting from the full life cycle environmental impact and risk control of the product, reform Mechanisms and systems to accelerate the development of a new economic model of recyclable, easily recyclable, and degradable plastics.

In addition, based on the research and analysis of the environmental footprint, the report puts forward the overall strategy of my country's "plastic control": classified management, reduction development, focusing on hot spots, and policy optimization and innovative development as the promotion and guarantee mechanism.
And further emphasized that my country’s future "plastic control" should seize hot spots such as supermarkets and catering stores, hot products such as plastic bags, disposable tableware, bundling and gift-type sales and packaging-type tying, and industry chain service guarantees Innovations include manufacturer packaging design innovation, takeaway tableware utilization model innovation, logistics packaging utilization model, and plastic recycling and classification innovation.
