The "manufacturing cost" of degradable plastics has become the bottleneck of development, and the price is up to 4.8 times that of traditional plastics

China has a complete range of degradable plastic products, including starch-based plastics, PBS (including PBAT and PBSA), PLA, PHA and PCL

The cost of degradable plastic products in my country is high

Substitution process hinders big

As the government's emphasis on plastic pollution continues to increase, China's degradable plastics industry has ushered in rapid development, and various products are relatively complete

From the statistics in the table above, except for starch-based plastics, the average selling price of other degradable plastics is 1.

Relatively low cost of PLA and PBAT

It is expected to become the mainstream product of the future industry

PLA is a polymer obtained by polymerizing lactic acid as the main raw material

PLA has relatively low cost among biodegradable plastics

PBAT is generally produced from aliphatic acids and butanediol by means of petrochemical or biological fermentation

From the cost structure of PBAT, the unit consumption of raw materials is 8993 yuan / ton, accounting for 71.

PLA and PBAT have good performance, the cost is relatively low among the current types of degradable plastics, the economic alternative is good, and the industry has great potential for development

Excellent performance of PHA

The future application space is expected to be further expanded

PHAs degradable plastics are intracellular polyesters synthesized by a variety of microorganisms.

Among the many degradable plastics, PHA has the most special degradable method, and the product performance is also very good

Due to the high production cost, the application range of PHA is relatively limited.

Epilogue

Overall, product performance is not the bottleneck for the development of degradable plastics in China, and the manufacturing cost is the key factor that determines whether degradable plastics can be marketed to replace traditional plastics
