It may come as a surprise for many, but the fat of some dead animals is being used to make. However, a new study warns that these "sustainable aviation fuels" may harm the planet.
Thecomes from Transport & Environment, a clean transportation campaign group based in Brussels. It emphasizes that there are not enough animals to meet the growing demand for animal-derived fuels in the aviation industry.
Unfortunately, a flight from Paris to New York would require fat from up to 8,800 slaughtered pigs.
The so called-sustainable fuel
Animal fats are typically regarded as waste-derived primarily from pigs, cattle, and chickens. As a result, it has been suggested that aviation fuel made from fats may have a lower carbon footprint.
