Sustainable aviation fuel (SAF) is a renewable alternative to traditional kerosene aviation fuel, produced from solid and liquid waste feedstock like household and agriculture waste, used oils, etc. The primary use of SAF is as an alternative aviation fuel to power aircraft, including commercial airliners, cargo planes, and military aircraft. SAF can be a drop-in replacement for conventional aviation fuel, requiring no modifications to aircraft engines or infrastructure. When used, SAF can significantly lower the carbon footprint of flights compared to using 100% conventional jet fuel.
