Climate change: Jet fuel from waste 'dramatically lowers' emissions

A new approach to making jet fuel from food waste has the potential to massively reduce carbon emissions from flying, scientists say. 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.<br/>
