【Hot attention from Chemical Machinery Equipment Network ] According to data, more than 330 million tons of plastic are produced every year, 500 billion plastic bags are used every year, and about 1 million plastic bottles are sold every minute.
This number is expected to increase by two by 2050.
Times.
At the same time, there are some plastic garbage basins in the ocean, which affects the marine environment.

In this context, plastic pollution control has been put on the agenda.

In 2020, my country has strengthened its efforts in this regard.
It has successively issued the "Opinions on Further Strengthening the Treatment of Plastic Pollution" and the "Notice on the Solid Advancement of Plastic Pollution Control", etc.
, making it clear that by the end of this year, the The use of non-degradable plastic bags, non-degradable disposable plastic straws, and non-degradable disposable plastic tableware is prohibited in places such as supermarkets, bookstores and other places in cities specifically designated in the plan.

Plastic recycling and biodegradable plastics are currently two major ways to reduce the use of plastics.

Plastic recycling or degradable plastic?

　　The industry believes that as a renewable resource, plastic recycling can better reduce the waste of resources and energy.
Many experts believe that the solution to plastic waste is to greatly increase the amount of recycled plastic, not to develop and use biodegradable plastics.

　　In this regard, some experts oppose it and point out that most plastics are degraded and recycled, the number of times of recycling is limited, and the utilization efficiency and value are gradually decreasing.
The phenomenon that the growth rate of plastic recycling and utilization is much slower than the growth rate of plastic production makes it impossible to become the main solution to plastic pollution.

　　Plastic recycling as a buffer for degradable plastics

　　Fundamentally, the reason why many people disagree with biodegradable plastics is mostly the price.

　　data shows that,For plastic products to meet the degradable standard, they need to meet the requirement that the material can be turned into carbon dioxide, etc.
, can be composted and disintegrated, and the compost residue will not affect biological growth, and it must not contain heavy metals.
This puts forward higher requirements on the technology of degradable plastics.
Therefore, in the immature market, the cost of the degradable plastics introduced * will be higher, which affects the acceptance of degradable plastics by consumers.

　　The editor believes that whether it is plastic recycling or degradable plastics, it is an important way for my country to promote the treatment of plastic pollution.
The realization of plastic recycling can buy more time for the improvement of degradable plastics.
The launch of the "Problems and Countermeasures for my country's Plastic Pollution Prevention and Control" project a few days ago in Beijing is a big signal.
It is understood that the project will put forward strategic suggestions on the recycling and reuse of waste plastics, related forecasts, technologies and development trends.

　　"Full" degradable plastics will "occupy" the market in the future

　　It is not easy to implement biodegradable plastics.
It is mainly manifested in two aspects.
One is technical difficulties, application scenarios differentiation, and costs.
The shortcomings are urgently needed to be filled; the other is that biodegradable plastics need to be implemented in related policy formulation, legal protection, Industry standards, market supervision, and certification systems are gradually standardized.

　　In September 2020, the "Guidelines for the Classification and Labeling of Degradable Plastic Products" were released, and the biodegradable plastics industry has taken another step toward standardization.

　　According to the data, from the perspective of degradation effect, it can be divided into "full" degradation and "partial" degradation.
The industry generally believes that fully degradable plastics will occupy the market in the future, and "partially" degradable plastics will be launched on the market.
In this process, plastic recycling will play a greater role and work with degradable plastics to reduce waste plastic production.
