Sustainable fuel for aircraft
Added on Fri April 30th, 2021
Air traffic produces a lot of pollution. In particular, commercial traffic alone contributes 3% of total global carbon emissions. Engineers and scientists are constantly looking for sustainable solutions for the fuel used.
In a study published in the Proceedings of the National Academy of Sciences, a team of researchers from the National Renewable Energy Laboratory in Golden, Colorado and other institutions show a viable method for converting food waste into sustainable fuel.
Creating a sustainable fuel for aircraft is a challenge because it has to be similar to what is used. Adapting aircraft engines for new types of fuel would be too time-consuming and costly.
Researchers have been able to use volatile fatty acids from the fermentation of old food waste and convert them into simple paraffin molecules that can be used in fuel and are really not that chemically different from traditional fossil fuels.
