en.Wedoany.com Reported - The Bio4PURConti project, coordinated by Covestro, has officially launched with the goal of developing the world's first continuous production process for bio-based aniline. The process uses a custom microorganism to ferment plant-based industrial sugars into intermediates, which are then chemically catalyzed to produce aniline containing 100% plant-based carbon, directly serving as a drop-in replacement for existing MDI and polyurethane value chains.

The project replaces traditional fed-batch fermentation with a continuous fermentation process, integrating cell recycling, real-time analysis, and downstream processing. The technology will be scaled from laboratory level to a 1.5 cubic meter semi-industrial demonstration, conducted at the Bio Base Europe Pilot Plant (Ghent) and Covestro (Leverkusen). The goal is to achieve higher space-time yields and significantly reduce the product carbon footprint (PCF).

The project consortium consists of 10 partners from seven countries, including industrial and academic institutions such as Fibenol Imavere, the University of Stuttgart, Bio Base Europe, the Norwegian University of Science and Technology (NTNU), and the VTT Technical Research Centre of Finland. The total project budget is €8.4 million, with €7 million funded by the European Union, and a project duration of 42 months. As a leading aniline producer with an annual capacity exceeding one million tons, Covestro is responsible for coordinating the scaling of this bio-based route.
