Covestro Korea announced on June 18 that it is participating in the EU-supported joint project 'Bio4PURConti' to advance the development of a continuous production process for bio-based aniline.
Aniline is a fundamental chemical used in the production of MDI (methylene diphenyl diisocyanate), a key raw material for polyurethane. MDI is utilized in insulation materials and automotive components. Currently, aniline production relies on fossil resources such as petroleum, resulting in approximately 20 million tons of carbon dioxide emissions globally each year from related processes.
Covestro has been developing a process to produce aniline using biomass derived from plants. This process involves creating intermediate substances through microbial fermentation, which are then converted into aniline that can be used in the same way as existing products through chemical reactions.
The project focuses on applying continuous fermentation processes instead of traditional stepwise production methods. Continuous fermentation allows for simultaneous raw material input and production, with an emphasis on verifying production efficiency and process stability.
Covestro also plans to confirm that the aniline produced through this process can be integrated into existing facilities without requiring modifications.
Demonstrations will take place at pilot facilities in Ghent, Belgium, and Leverkusen, Germany. The scale will be approximately 1.5 cubic meters, testing process efficiency and applicability under conditions close to actual production.
The Bio4PURConti project involves 10 institutions from seven countries, including Germany, France, Belgium, Finland, Estonia, Spain, and Norway. It is a collaborative European research initiative involving both industry and academia.
The total project cost is approximately 8.4 million euros, or about 12 billion won, with 7 million euros funded by the EU's Circular Bio-based Europe Joint Undertaking (CBE JU). The project duration is 42 months.
Covestro has an annual production capacity of over 1 million tons of aniline. The company aims to validate the industrial applicability of production processes using bio-based raw materials through this project.
Additionally, Covestro has demonstrated its corporate social responsibility by participating in cleaning and memorial activities at the National Cemetery in Seoul on Memorial Day.
