About
LanzaTech Global is a carbon recycling company that transforms carbon-rich industrial waste gases into sustainable fuels, chemicals, and materials using a proprietary gas fermentation bioprocess. Founded in 2005 in New Zealand and now headquartered in Skokie, Illinois, LanzaTech licenses its technology to industrial partners worldwide — enabling steel mills, chemical plants, and refineries to capture carbon monoxide, carbon dioxide, and hydrogen from flue gases that would otherwise be vented or flared, and bioconvert them into ethanol, sustainable aviation fuel (SAF), and chemical feedstocks. This process does not compete with food crops, requires no arable land, and operates at scale within existing industrial infrastructure.
