Currently, most of the food scraps that are used for energy around the world are converted into methane gas.
But researchers in the US have found a way of turning this waste into a type of paraffin that works in jet engines.
The authors of the new study say the fuel cuts greenhouse gas emissions by 165% compared to fossil energy.
This figure comes from the reduction in carbon emitted from airplanes plus the emissions that are avoided when food waste is diverted from landfill.
