Covestro has started up a pilot plant to make aniline from sugar.

Covestro has started up a pilot plant at its site in Leverkusen, Germany, for making biobased aniline. Aniline is a precursor to the polyurethane raw material methylene diphenyl diisocyanate. The new plant uses a microorganism to transform sugar into an intermediate that is then converted into aniline through a catalytic step. Conventionally, aniline is made from the petrochemical nitrobenzene.
