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%.
With the development of battery-powered airplanes for long haul flights a distant prospect at this point, much attention has focussed on replacing existing jet fuel with a sustainable alternative.
In fact the UK government has just announced a £15m competition to encourage companies to develop jet fuel from household waste products. You can read the full report through Zureli by clicking here.
