Scientists Have Found a Way to Turn Food Waste into Jet Fuel

Mar. 27, 2021

Technology, as we all know, is developing fast, and so is the rate of global warming in our world. As a result, we have seen various researchers and major companiescome up with waysto reduce thecarbon footprintin today’s world. Even the automobile industry isgradually shiftingfrom gas-powered vehicles toelectric ones. However, it is tough for the aviation industry, which accounts for almost 2.5% of carbon emissions, to make the shift. So now, scientists have come up with a way to create jet fuel for airplanes using food waste.

Bio-Fuel for Planes Made From Food Scraps

As per areportbySingularity Hub, the aviation sector has been working on various ways to reduce its carbon footprints. There are manycompaniesthat aredeveloping electric planes. However, with today’s battery tech, it is difficult to balance the power and the weight to keep a plane afloat.

So, scientists and researchers started working on a liquid alternative to jet fuel that has the same energy density. They were reportedly successful in creating biofuel for airplanes using food waste. However, the final result did not match the industry-standard previously.

Now, in a recentpaperpublished on the Proceedings of the National Academy of Sciences of the USA (PNAS), the scientist claims that they have come up with a new way to produce food-scrap-based biofuels that meet the current aviation standards.

Previously, the researchers turned wet waste like food scraps, wastewater sludge, and animal manures into volatile fatty acids (VFAs). These were eventually upgraded into jet fuel.

In the new process, however, the researchers use a catalyst to add extra carbon to the VFA molecules. This converts them into paraffin which is similar to standard jet fuel used in commercial flights. So, the researchers mixed 10% of the paraffin with 90% of standard jet fuel to create a biofuel version that meets the industry standard.

“If our refining pathway is scaled up, it could take as little as a year or two for airlines like Southwest to get the fuel regulatory approvals they need to start using wet waste sustainable aviation fuel in commercial flights.That means net-zero-carbon flights are on the horizon earlier than some might have thought,”states the lead author of the paper, Derek Vardon.
