LanzaTech is a carbon capture and utilization (CCU) and industrial biotechnology company that develops and licenses gas fermentation technology to convert carbon-rich waste gases and syngas from steelmaking, refining, and other processes—as well as biogenic feedstocks—into ethanol and other chemicals. Its proprietary microbes biologically ferment CO, CO₂, and hydrogen to produce chemical building blocks, offering a route to valorize off-gases and lower lifecycle emissions.
The company partners with heavy industry and waste handlers to deploy commercial-scale plants and integrate output into fuels and chemicals value chains. Produced ethanol can be used directly, upgraded into sustainable aviation fuel via alcohol-to-jet pathways (through affiliated technologies), or converted into intermediates for polymers and consumer products. Founded in 2005 and headquartered in the United States, LanzaTech operates globally through joint ventures and technology licensing.
