Wichita, Kansas - Invista has linked with Lanzatech to develop renewably-sourced butadiene. The two companies plan to develop one-step and two-step technologies to convert industrial waste gas carbon monoxide into butadiene.
The initial focus will be on a 2-step process to produce butadiene monomer from LanzaTech carbon monoxide-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.
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.
Invista is building internal biotechnical capability to develop biological routes to its products and feedstocks.
LanzaTech's 15,000 gal/year pilot facility at a steel mill in New Zealand produces ethanol and 2,3 BDO from waste carbon monoxide gas. In Shanghai, China, LanzaTech's 100,000-gallon-per-year demonstration uses waste gases from a Baosteel-operated steel mill to produce ethanol.
