At present, the global production capacity of biodegradable plastics such as PLA, PHA, PBAT, PPC is about 1000kt, with an annual growth rate of more than 20%. At this stage, how many companies in the world produce degradable plastics? What is the capacity situation? Hay Think will introduce you to PHA, dibasic acid glycol copolyester [PBAT, PBS, polysuccinic acid-butylene adipate (PBSA)], PPC domestic and foreign production enterprises and production capacity.
PHA is a large family of materials. At present, more than 150 different monomer structures have been discovered, but only a few are actually produced on a large scale.
Global leading manufacturers
Currently, global leading manufactuters that produce PHA mainly include Metabolix in USA,Kaneka in Japan, Biocycle in Brazil and Biomers in Germany.
China's leading manufacturer
In the field of PHA materials, China is at the international leading level.
NBTA Biomaterial Technology Co., Ltd. has a PHA production line with an annual output of 2kt; TJGY Biotechnology Co., Ltd.[Ranked second in the world in terms of technology and production capacity] currently has a PHA production line with an annual output of 10kt, and plans to build a 100kt-scale production line in Jilin. BJLJ Microbial Technology Co., Ltd. announced in December 2017 that it had completed the pilot production of the biodegradable material PHA. In early 2018, the company established a research and development center in Shenzhen and put it into operation. In 2019, it signed a strategic cooperation agreement with Tsinghua University and Sinochem International Lightweight Materials Division to use low-priced seawater as a substrate to realize the industrialization of PHA and possibly realize low-cost production technology.
Global dibasic acid glycol copolyester [PBAT, PBS, polysuccinic acid-butylene adipate (PBSA)]
The global production capacity of dibasic acid glycol copolyester [PBAT, PBS, polybutylene adipate (PBSA)] has exceeded 400 kt/year, and China’s production capacity has exceeded 200 kt/year. Although PBS and PBSA were developed earlier, but due to their own performance limitations, the market consumption is not as good as PBAT. At present, the global production of dibasic acid glycol copolyesters is mainly based on PBAT. Because of its high toughness, PBAT is used in large quantities in the production of various film products.

China's leading manufacturers
China's current major manufacturers of dibasic acid glycol copolyester raw materials include:
ZHWT Chemical Co., Ltd., GZJF Technology Co., Ltd., XJLS Chemical Co., Ltd., JHZL Material Technology Co., Ltd., and HZFX Technology Co., Ltd. In addition, many companies including NTLD Bio-New Material Technology Co., Ltd., GSMG Polyhe Environmental Protection New Material Technology Co., Ltd., YKKH Petrochemical Co., Ltd., CQHD Bio-Materials Co., Ltd., HBLR New Material Technology Co., Ltd., have a capacity under construction of more than 100kt It is expected that the total production capacity of PBAT and PBS will be around 250kt/year by the end of 2020. In addition, large group companies such as ZJHF New Materials Co., Ltd., TC New Materials Group Co., Ltd., LXJT Synthetic Materials Technology Group, and YTHX Chemical Group Co., Ltd. are also preparing for the construction of PBAT production lines. It can be predicted that PBAT will basically be able to Meet China's demand for biodegradation after the implementation of the ban on plastic pollution prevention and control.
PPC
