Within a few years, food waste could be fueling our airplanes.
Researchers have worked out a way to transform food scraps, used cooking oil, animal manure and wastewater sludge into jet fuel with a carbon footprint 165% lower than standard jet fuel, according to a new study published in the Proceedings of the National Academy of Sciences.
