LanzaTech and LanzaJet Introduce CirculAir for Sustainable Aviation Fuel

LanzaTech Global, Inc. (NASDAQ:LNZA), the carbon recycling company transforming waste carbon into sustainable fuels, chemicals, and materials, and LanzaJet, Inc., a leading sustainable fuels technology company and fuels producer, are launching CirculAir™, a new joint offering to convert waste, carbon, and renewable power into sustainable aviation fuel (SAF) and immediately accelerate decarbonization of the aviation industry globally. CirculAir is a breakthrough offering that provides an economical and commercialized alternative to Fischer-Tropsch technology to create eFuels, Power-to-Liquids (PtL), and Waste-to-Fuels leveraging the already ASTM-approved SAF production pathway that uses ethanol as the biointermediate and Alcohol-to-Jet (ATJ) technology to produce SAF and Renewable Diesel (RD).
 

CirculAir is a formalized joint offering and end-to-end technology solution that turns nearly any waste source including municipal solid waste (MSW), agricultural residues, carbon emissions from industrial and refining processes, carbon dioxide (CO2) through direct air capture, and renewable power into SAF. CirculAir combines the groundbreaking technologies of LanzaTech and LanzaJet to form an efficient and economically compelling offering that provides the aviation industry with a solution to produce waste-based SAF on a global scale. CirculAir will combine LanzaTech and LanzaJet's technologies; first incorporating LanzaTech's novel gas fermentation technology to convert nearly any waste resource into CarbonSmart™ ethanol and then second, executing LanzaJet's Alcohol-to-Jet (ATJ) technology by taking the ethanol and converting it to drop-in SAF. The SAF made through this process is expected to reduce aviation emissions by at least 85% and can also produce carbon negative results, depending on the feedstock.

SAF is estimated to account for 65–70% of overall aviation emissions reduction to achieve net zero by 2050, making it a critical tool for this hard-to-abate industry; however, historic supply constraints, high costs, and technical barriers have made it difficult for the industry to default to SAF as the primary fuel source. CirculAir breaks down these barriers. The technology is able to turn a wide range of waste-based feedstocks into SAF, and it is being adopted by a range of customers across the globe. This widespread adoption is projected to accelerate the production and economies of scale necessary to bring down the global cost of SAF.
