Palm oil is a critical component in the formulation of sustainable aviation fuel (SAF), but the increased exploitation of this material has resulted in extensive deforestation and significant carbon dioxide (CO2) emissions, underscoring the need for environmentally sound alternatives. A sustainable palm oil substitute is now available as a result of research conducted by Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, Mibelle Group and LanzaTech Global, Inc.

The dual fermentation technology transforms waste CO2 gases into alcohol and further into a palm oil-like fat using non-genetically modified oil yeasts in a secondary fermentation process. Following successful laboratory trials at Fraunhofer IGB and promising application tests at Mibelle laboratories, efforts are now focused on scaling up production of this hydroprocessed esters and fatty acids process engineered by LanzaTech.

Alcohol from the LanzaTech process is already a feedstock for SAF production. Via the Alcohol to Jet Process, LanzaTech’s technology enables the production of advanced SAF, and when the ethanol is made from CO₂ and green hydrogen, e-fuels are manufactured as replacements for conventional petroleum-based fuels.

The technology not only reduces reliance on palm oil but also opens the door to more sustainable supply chains.
