Jet fuel from waste ‘dramatically lowers’ emissions

Updated: Apr 2, 2021



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


A report published by Zureli shows 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.


The aviation industry worldwide is facing some difficult decisions about how to combine increased demand for flying with the need to rapidly cut emissions from the sector.


In the US, airlines currently use around 21 billion gallons of jet fuel every year, with demand expected to double by the middle of the century. At the same time, they have committed to cutting CO2 by 50%.
