Butadiene is an important intermediate chemical used in the production of synthetic rubber and various plastics. It is also a key intermediate chemical used by INVISTA in its proprietary, butadiene-based adiponitrile (ADN) production technologies. Source
The collaboration will initially focus on the production of butadiene in a 2-step process from LanzaTech CO-derived 2,3-butanediol (2,3 BDO). A direct single step process will also be developed to produce butadiene directly through a process of gas fermentation. Source
