Covestro has launched and is coordinating Bio4PURConti, an EU-funded initiative to develop the world’s first continuous production process for bio-based aniline. Aniline is a key raw material for the plastics and chemical industry, notably for MDI (methylene diphenyl diisocyanate) used in polyurethane production.

What technical or supply-chain hurdles do you think will be most challenging in scaling continuous, bio-based aniline production, and where could this have the biggest impact in the polyurethane value chain?

Continuous bio-based aniline sounds promising, but the real battle is feed variability and holding polymer-grade specs steady for MDI units. If this is fermentation-based, how are you handling amine compatibility in continuous pumps and seals (NBR swells; PTFE/FFKM hold up) and phase separation/solvent carryover? A buffer with inline UV-Vis/NIR could smooth swings, but that’s nontrivial at scale.
