“Currently, all production equipment has been debugged. Once the project acceptance is completed, the country’s first bio-based carbonate production line will be officially put into production. When the project reaches full production, it will be able to produce 10,000 tons of bio-based carbonate per year. The by-product is 6,500 tons of methanol.” Standing in the control room of Bengbu Jingu Biotechnology Co., Ltd., General Manager Wang Haigao said proudly, “At present, the internal facilities of the factory are temporarily kept secret from the outside world. After all, it is the first in the country.”
Bengbu Jingu Biotechnology Co., Ltd. is a holding subsidiary of Anhui Fengyuan Biotechnology Co., Ltd.. It was established in January 2022 and is located in Guzhen Economic Development Zone with a total investment of 1.6 100 million yuan. Construction will start in July 2022. It is a manufacturing enterprise mainly engaged in the production of bio-based carbonate. The company’s bio-based carbonate project with an annual output of 10,000 tons has passed the first domestic chemical process safety and reliability demonstration, and now has the conditions for input and production.
Through the limited monitoring screen on the wall of the control room, the “secrets” of the bio-based carbonate production line can be explored. “In the control room, the liquid raw materials for the production of bio-based carbonate can be directly transported to the production workshop through pipelines to realize operations such as automatic quantification, automatic feeding, automatic temperature rise, etc., and the primary product can be processed twice by thermally decomposing the raw materials twice. After separation and impurity removal, it is cooled and crystallized through a special process, and the finally processed bio-based carbonate can be transported to the packaging workshop along with the pipeline for filling.” Wang Hai introduced the main process of bio-based carbonate production to reporters.
Bengbu Jingu Biotechnology Co., Ltd.: Extend the plastic-free industrial chain and build the world’s first bio-based carbonate production line.
The bio-based carbonate production line of Bengbu Jingu Biotechnology Co., Ltd. is produced through the patented technology of “Trimethylene Carbonate Preparation Method and Purification Method” and can be matched with the industrial policy of Fengyuan Group. The use of bio-based carbonate Modify polylactic acid to improve the mechanical properties of polylactic acid products.
Polylactic acid is a new type of biodegradable material, which is made from biomass raw materials through fermentation and polymerization. It has excellent properties that many petroleum-based plastics do not have. Although it has high tensile strength and flexural strength, it has poor toughness, high brittleness, and an elongation at break of less than 10%. This characteristic greatly limits the application of polylactic acid in certain specific fields.
“Modification of polylactic acid through bio-based carbonate can greatly reduce modification costs, promote the extension of Fengyuan Group’s polylactic acid products to the downstream of the industrial chain, and promote the development of biaxially oriented film, foamed elastomer and other industries. , to better expand the application fields of polylactic acid materials.” Wang Hai said that after modification, polylactic acid will have more space for utilization, which is of great significance to promoting the application of polylactic acid.
The bio-based carbonate produced by the production line can not only modify polylactic acid, but also produce polycarbonate, high molecular weight polyester resin, and epoxy resin hardener through the manufacture of derivative products. It can replace traditional petroleum-based materials and is widely used. It is used in composite materials, automotive interiors, household products, aviation, medical and other industries, and has excellent characteristics such as green, non-toxic and environmentally friendly. Methanol, a by-product of the production process, is a widely used chemical raw material, used to make formaldehyde and pesticides, and is used as an extraction agent for organic matter and a denaturant for alcohol.
“Under the ‘double carbon’ goal, bio-based carbonate has broad development prospects.” Wang Hai said that after the bio-based carbonate production line project is officially put into operation, it is expected to achieve an annual output value of 309.7 million yuan and a total annual profit and tax of 118 million yuan. .
