The bio-based BDO industry has broad development prospects and domestic production capacity is accelerating the release

Bio-based BDO, namely bio-based 1,4-butanediol, refers to BDO prepared from bio-based materials as raw materials. Bio-based BDO production methods mainly fall into two categories: one-step method and two-step method. The one-step method refers to the method of producing bio-based BDO through direct fermentation using sugars, water, inorganic salts and microorganisms as raw materials; the two-step method refers to using bio-based BDO derived from biomass or sugar substrates. A method of preparing bio-based BDO using acid (succinic acid) as raw material and going through esterification, hydrogenation, purification and other steps.

According to the “2023-2028 Bio-based 1,4-butanediol (bio-based BDO) industry market in-depth research and investment prospect forecast analysis report” released by the Industrial Research Center 》 It shows that bio-based BDO has the advantages of green environmental protection, low production cost, low carbon emissions in the production process, renewable raw materials and sufficient supply. Its comprehensive performance is better than petroleum-based BDO and can be widely used in clothing. , electronics, shoe materials, building materials, spandex, polyurethane, degradable plastics, new energy batteries and other fields.

Among them, degradable plastics are the main application areas of BDO. Under the current background of the continued implementation of domestic plastic restriction orders, the development of the degradable plastics market continues to accelerate. As an important raw material for degradable plastics PBS and PBAT, BDO’s demand continues to increase and its output continues to increase. Domestic BDO production capacity will exceed 2.2 million tons in 2022. At present, domestic BDO production capacity is still dominated by petroleum-based BDO, and bio-based BDO production capacity is relatively low.

However, degradable plastics prepared from bio-based BDO as raw materials are biodegradable plastics that meet international biomass content standards. In the future, under the background of the continuous advancement of domestic dual-carbon goals and the continuous strengthening of environmental protection supervision, bio-based BDO will replace petroleum-based It will be a general trend for BDO to become the mainstream of the BDO market, and the industry has broad prospects for development.

Bio-based BDO has high technical barriers. Currently, there are only a few companies with large-scale mass production capabilities globally. The main companies include BASF in Germany, Genomatica in the United States, Novamont in Italy, DSM in the Netherlands, Mitsubishi Chemical in Japan, Yuanli Chemical Group in China, etc. , mostly international companies, and only one domestic company has mass production capabilities. At present, the domestic production capacity of bio-based BDO is about 15,000 tons/year. The supply and demand market is in short supply, and the market demand space is huge.

In addition to Yuanli Chemical Group, domestic companies such as Shandong Landian Biotechnology and Kingfa Technology are actively deploying the bio-based BDO market. In the future, under the background of the gradual implementation of production capacity of local companies, the gap between domestic bio-based BDO supply and demand will gradually narrow, and industry development The trend is improving.

Industry analysts said that bio-based BDO is a basic chemical raw material with excellent comprehensive performance. In the future, under the background of the continuous advancement of domestic dual-carbon goals and the continuous strengthening of environmental protection efforts, bio-based BDO is expected to replace petroleum-based BDO and become the mainstream of the BDO market, and the industry development prospects are promising. At present, there is one domestic enterprise, Yuanli Chemical Group, which has the mass production capacity of bio-based BDO. At the same time, many companies are actively deploying the market. my country’s bio-based BDO production capacity is accelerating and is expected to become one of the world’s major producers in the future.
