●  The global plastic restriction и plastic ban policies continue to advance, и 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 и are expected to become the largest category in  the future

Plastics are widely used in production и life с excellent performance и 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%, и the annual consumption of plastics will reach 700 million tons in 2030. In the natural environment, it generally takes 200-700 years to degrade, и there is a large amount of waste plastics.

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

Use degradable plastics to reduce garbage pollution. In January 2020, the China Development и Reform Commission's "Opinions on Further Strengthening the Treatment of Plastic Pollution" clarified the time point для 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, и 2.6 million tons of take-out packaging every year.

With the rapid development of express delivery и takeaway businesses, the demand для plastics continues to grow. для 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 с technological progress, large-scale production, cost reduction, и 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 и molding, и excellent biocompatibility. Currently full

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

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