LanzaTech

LanzaTech is an industrial biotechnology company founded in 2005 and headquartered in Skokie, Illinois, United States. The company develops gas fermentation technology that converts carbon-rich waste gases and syngas from steel mills, refineries, and municipal solid waste into ethanol and other chemical building blocks, addressing industrial reliance on fossil carbon feedstocks.

The core technology uses proprietary microorganisms housed in fermentation bioreactors to convert carbon monoxide, carbon dioxide, and hydrogen into ethanol, sustainable aviation fuel precursors, and nutritional protein. LanzaTech licenses its platform to industrial partners such as ArcelorMittal and SEKISUI Chemical, and as of 2026 the technology operates across six commercial facilities worldwide.

1. Gas Fermentation Platform: Proprietary microorganisms convert CO, CO2, and hydrogen-rich waste gas into ethanol and chemical intermediates.

2. Sustainable Aviation Fuel: Ethanol output is upgraded into SAF through the alcohol-to-jet pathway.

3. Nutritional Protein: A dedicated protein line produces protein directly from captured CO2.

4. Industrial Licensing: The platform is licensed to steel, waste, and chemical industry partners rather than operated solely by LanzaTech.

5. Commercial Scale: Six commercial gas fermentation facilities were operating as of 2026, including a municipal solid waste plant in Japan.
