Lipids to biojet and sustainable aviation fuel: uses and competing demands for lipid feedstocks

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The use of biojet and sustainable aviation fuels (SAF) as low carbon‐intensity (CI) fuels is likely to be the primary pathway to decarbonize aviation. ‘Waste lipids’, such as fats, oils, and greases (FOGs), are preferred feedstocks due to their lower CI. However, they are mainly used to make biodiesel or renewable diesel.
