Succinic acid has a wide range of applications, and degradable plastic PBS is its main application area.

Succinic acid, also known as succinic acid, ethylenedicarboxylic acid, ethylenedicarboxylic acid, etc., is a dicarboxylic acid. Succinic acid can undergo various reactions such as dehydration, halogenation, esterification, sulfonation, acylation, oxidation, reduction, etc. It is an important organic chemical raw material and is widely used in medicine, degradable plastics, food, fiber, and metal processing. and pesticides, among which degradable plastic PBS is currently the main application field of succinic acid.

According to the “2022-2027 Succinic Acid Industry Venture Investment Situation and Investment and Financing Strategy Guidelines Report released by the Industrial Research Center, Globally, succinic acid production capacity is mainly distributed in China, Canada, Italy, Japan and other regions. China is the world’s largest succinic acid producer. In 2021, the global succinic acid production capacity will be about 116,000 tons, of which China The production capacity ratio is as high as 45.8%.

From the perspective of production technology, the current production technology of succinic acid is mainly divided into three types: catalytic hydrogenation, electrolysis and biological fermentation. European and American companies mainly use biological fermentation. Due to the immature domestic biological fermentation synthesis technology, my country’s succinic acid The production process is still dominated by electrolysis, followed by catalytic hydrogenation. The electrolysis method has high energy consumption, difficult maintenance of electrolyzers, and large amounts of sewage discharge. In the context of increasingly stringent environmental protection requirements, the electrolysis method will gradually be eliminated. In the future, the development of the succinic acid industry will continue to be high-end, green, and large-scale. direction development.

my country’s succinic acid industry is large-scale. The major manufacturers in the industry include Shandong Landian, Shandong Feiyang, Jinhui Zhaolong, Anhui Sanxin, Anqing Hexing, Baoji Jinbao, Jiangsu Shuguang and other enterprises. Among them, Shandong Landian is one of the few domestic enterprises that adopt biological Enterprises producing succinic acid through fermentation process. Due to production process limitations, my country’s succinic acid is currently mainly mid- to low-end industrial grade products. The supply capacity of high-end succinic acid such as food grade, pharmaceutical grade and electronic grade is weak, and market demand still relies on imports.

At present, degradable plastic PBS is the main application field of succinic acid, accounting for up to 70% of the application. As environmental protection supervision becomes increasingly strict, the production capacity of degradable plastic PBS will continue to increase. It is expected that in 2026, the new production capacity of degradable plastic PBS in my country will Reaching 4.868 million tons/year, the demand for succinic acid in degradable plastic PBS will be further released. Attracted by the good market prospects, domestic companies have begun to plan to build or expand succinic acid devices. It is expected that my country’s succinic acid production capacity will reach 450,000 tons in 2026.

Industry analysts said that my country is the world’s largest producer of succinic acid, but due to production technology limitations, my country’s succinic acid production capacity Most of them are concentrated in the mid- to low-end fields, and the supply capacity of high-end products needs to be further enhanced. Succinic acid has a wide range of applications, among which degradable plastic PBS is the most important application scenario. As environmental protection supervision becomes increasingly strict, the succinic acid market has broad development space. In the future, industry development will continue to upgrade to high-end, green, and large-scale directions. .
