Creating a promising aviation fuel from potato production wastes is a possibility in laboratory conditions. The BioJet Fuel project, running from 2017 to 2020, aimed to define the conditions needed to scale this process and create a viable production chain for bio-based aviation fuels.
The raw materials used are potato residual streams from potato processing. This is used for the enzymatic production of acetone, butanol and ethanol (ABE fermentation). The ABE mixture obtained from the substrate is converted to hydrocarbons and after hydrogenation and fractionation to aviation fuel.
Potato peelings are used as low-value feed for cattle and can be converted into methane by anaerobic digestion. Studies have shown that the complete production chain of converting agricultural waste into fuel is already technically feasible.
