LanzaTech, LanzaJet announce end-to-end SAF production technology


LanzaTech Global and LanzaJet have launched CirculAir to convert waste, carbon, and renewable power into sustainable aviation fuel (SAF).

CirculAir is a breakthrough offering that provides an economical and commercialised alternative to Fischer-Tropsch technology to create eFuels, power-to-liquids and waste-to-fuels leveraging the already ASTM-approved SAF production pathway that uses ethanol as the bio-intermediate and alcohol-to-jet technology to produce SAF and renewable diesel, said the joint statement issued by renewable fuel companies.

“CirculAir brings to market a revolutionary, integrated pathway to convert carbon and waste inventories across our global society as well as the ability to utilise emerging renewable power supply and CO2 through direct air capture as an economical and commercially viable approach to creating SAF,” said Jimmy Samartzis, CEO, LanzaJet.

The companies said that CirculAir uses technology to turn various waste materials into SAF on a large scale.

The feedstocks that can used include trash from cities (municipal solid waste), leftover materials from farms (agricultural residues), factory emissions (carbon emissions) and CO2 captured directly from the air.

The two firms are currently developing joint projects throughout the world, including Australia, New Zealand, the United Arab Emirates, and the United Kingdom.

“Over 100bn gallons of fossil fuel-derived jet fuel are consumed each year – with our joint technology, we can turn that into 100bn gallons of reliable jet fuel powered by recycled carbon,” said Dr. Jennifer Holmgren, CEO, LanzaTech.

“In joining forces with CirculAir, LanzaTech and LanzaJet are making it clear that versatile, abundant waste carbon can give us what we need to help people travel and eliminate our dependence on fossil resources.”
