●  The global plastic restriction and plastic ban policies continue to advance, and the degradable plastics market is promising.

●  Polylactic acid: the rising star of bio-based biodegradable plastics, lactide restricts the effective expansion of the industry.

●  PBAT: Petroleum-based biodegradable plastics have obvious cost advantages and are expected to become the largest category in  the future

Plastics are widely used in production and life with excellent performance and low cost. From 1950 to 2015, humans have produced 8.3 billion tons of plastic products. Estimated global plastic consumption

It will grow at an annual rate of 8%, and the annual consumption of plastics will reach 700 million tons in 2030. In the natural environment, it generally takes 200-700 years to degrade, and there is a large amount of waste plastics.

It has threatened the health of wild animals and humans to a great extent. Therefore, in the face of huge amounts of white pollution, various countries actively promote plastic restrictions, bans, and development.

Use degradable plastics to reduce garbage pollution. In January 2020, the China Development and Reform Commission's "Opinions on Further Strengthening the Treatment of Plastic Pollution" clarified the time point for the ban on plastics. Short-term policy

Under the driving situation, degradable plastics are expected to achieve accelerated replacement. 

According to statistics, China consumes about 4 million tons of shopping bags, 2.46 million tons of agricultural films, and 2.6 million tons of take-out packaging every year.

With the rapid development of express delivery and takeaway businesses, the demand for plastics continues to grow. For these fields, degradable plastics are particularly suitable. Assuming a replacement of 10%, more than 900,000 tons can be added

Degradable plastic demand. We believe that with technological progress, large-scale production, cost reduction, and improvement of environmental protection concepts, degradable plastics will grow more than 10 times in the future.

Polylactic acid is a polymer material produced by polymerization of lactic acid as raw material. It has the characteristics of non-toxic, non-irritating, high strength, easy processing and molding, and excellent biocompatibility. Currently full

The annual production capacity of spherical polylactic acid is 240,000 tons, and the output is about 200,000 tons. The main consumption area is packaging materials, accounting for about 65% of the total consumption, followed by the biomedical field, accounting for about 65% of the total consumption.

26% of consumption. At present, the production of polylactic acid mainly adopts the lactide ring-opening polymerization process.
