Bio-based PBS (polybutylene succinate) has more development prospects. Domestic production capacity is small

Polybutylene succinate (PBS) is a high molecular polymer with a milky white appearance, odorless and tasteless, excellent mechanical properties, good heat resistance, almost insoluble in water, methanol and ethanol, and can be used in a variety of processes for processing. Because it contains easily hydrolyzable ester groups, PBS can be decomposed by a variety of microorganisms in nature and enzymes in animals and plants, and is eventually decomposed into carbon dioxide and water. It is a biodegradable plastic with excellent performance.

In 2021, the global polybutylene succinate (PBS) market will be approximately 1.51 billion yuan; it is expected that from 2021 to 2026, the global polybutylene succinate (PBS) market will continue to grow at an annual rate of approximately 14.9%. With an average compound growth rate, the market size will reach about 3.02 billion yuan by 2026. With economic development, global production and sales of plastic products continue to grow. Ordinary plastics are difficult to degrade and are harmful to the environment. Biodegradable plastics have attracted attention. PBS is one of the products with the best comprehensive performance among degradable plastics, so the market is growing rapidly.

According to the“Bio-based PBS (Polybutylene Succinate) Industry In-depth Market Research and Investment Strategy Suggestions Report 2022-2026” released by the Industrial Research Center It shows that according to raw materials, PBS can be divided into two categories: petroleum-based PBS and bio-based PBS. Petroleum-based PBS is produced using petroleum resources. It is made from petroleum-based succinic acid and petroleum-based butylene glycol as raw materials, adding a catalyst through polycondensation. Petroleum resources are non-renewable energy. In order to cope with the energy crisis and achieve sustainable development, biological resources have become the focus of the global materials industry to replace fossil resources. Bio-based polymer materials have broad prospects in the field of replacing traditional petroleum-based polymer materials. Therefore, in the long run Look, bio-based PBS has more development prospects.

Bio-based PBS is made from bio-based succinic acid and bio-based butylene glycol as raw materials, adding efficient catalysts through polycondensation reaction. Bio-based butanediol is prepared from bio-based succinic acid, so bio-based succinic acid is an important raw material for the production of bio-based PBS. Bio-based succinic acid is prepared by using renewable biomass resources and carbon dioxide as raw materials and using microbial fermentation. At present, its production process has matured. The main domestic production companies include Yangzi Petrochemical, Landian Biotech, etc., which are my country’s bio-based PBS. The foundation has been laid for the development of the industry.

Industry analysts said that my country’s PBS production companies mainly include Anqing Hexing Chemical Industry, Kingfa Technology, Shandong Huiying New Materials, etc., in 2021 In 2017, Guang’an Hongyuan Technology, Hubei Yihua Degradable New Materials, Zhejiang Changhong Biomaterials, etc. planned to build or started construction of PBS production capacity. The scale of my country’s PBS industry is constantly expanding. However, my country’s PBS is mainly petroleum-based PBS, and petroleum-based PBS is the representative product of petroleum-based degradable plastics in my country. However, the bio-based PBS industry has developed slowly, and bio-based degradable plastics are represented by polylactic acid (PLA). From this point of view, the development of my country’s bio-based PBS industry will face certain challenges in the future.
