Do you know the significance of using biodegradable plastics?

Plastic is a major invention of the 20th century, and it is also one of the common chemical products. We can see it in every aspect of life: express packaging, takeaway boxes, supermarket shopping bags, plastic bottles, etc.

Plastic can replace many materials, and is convenient to use, store and transport, which has promoted the rapid development of express delivery, takeaway and other industries. However, plastic bags will not degrade for hundreds of years and have a great impact on the environment. White pollution has become a world-recognized environmental problem.

According to statistics from the Plastics Committee of the China Plastics Association, our country uses about 3 billion plastic bags every day, which means that each of us is responsible for the pollution of 2-3 plastic bags per day. But at the moment, we’ve reached a point where we’re very dependent on plastic.
In order to get rid of this predicament, our country has already started to act. Published recommendations on plastic pollution control, which mentioned that non-degradable plastic bags should be banned in various places and activities. This is a policy that people look forward to! A small step for China to reduce plastic, a big step for the world to reduce plastic!

The “Opinions on Further Strengthening Plastic Pollution Control” (hereinafter referred to as the Plastic Restriction Order) issued in January 2020 prohibits or restricts the production and sales of products including disposable plastic shopping bags and tableware, and sets an exit time.
The rapid elimination of a large number of disposable non-degradable plastic products has led to a rapid increase in the production capacity of substitutes in a short period of time. Among them, biodegradable plastic bags are a good example and the focus of everyone’s attention.

As the main raw materials of biodegradable plastic bags, PLA and PBAT, a professor predicted that by 2025, the annual production capacity of these two major biodegradable plastics in China will increase from about 100,000 tons and 300,000 tons in 2020 to 1 million. tons and more than 7 million tons, reaching more than half of the global production capacity.
The development of biodegradable plastics has been slow in the early stage. The main reason is that the production cost is high and the promotion is not enough. However, with the ban on the import of foreign garbage in China since 2018, the industry trend has changed significantly.

In the past, a large amount of plastic waste from overseas developed countries was exported to China and other regions, which actually solved the huge external costs at a small cash cost; while China has borne additional external costs, and the burden has become heavier and heavier.
In order to solve the serious waste problem, China has banned the disposable plastic using. European countries have also introduced various policies to address the plastic problem, and the country has become more and more strict, so biodegradation The plastic industry has entered an explosive period, and polylactic acid (PLA) and PBAT are promising materials among them, opening up a new field of environmentally friendly plastics in China.

In the future, starting from the innovation of Chinese standards, biodegradable plastics will integrate the hard-core technologies of international standards, national standards, group standards, and enterprise standards to achieve petrochemical material innovation, non-ji material substitution, and bio-based and biodegradable plastics. In addition, thousands of sails are competing to replace plastic step by step, solve white pollution, and benefit mankind.
