- Researchers have developed a way that airplanes could be fueled by food waste.
- The fluid is made up of volatile fatty acids found in decaying food waste which, through a chemical process, are turned into kerosene, also known as jet fuel.
- According to the researchers, wet wastes, including food leftovers, could provide raw material for up to 15 billion litres of sustainable aviation fuel per year. Another 19 billion litres could come from treating fats, oils, and greases with hydrogen.
