SAF – Sustainable energy for aviation

“Sustainable aviation fuel”, so called SAF, is the general term for renewable or waste-derived fuels that are chemically very similar to fossil jet fuel. As a result, they can easily complement and replace the conventional equivalent used in aviation. The production processes for SAF are very different. What they have in common, however, is that they cause significantly less CO2 emissions than fossil jet fuels. This should greatly reduce emissions in air traffic in the future.

SARIA and the French multi-energy company TotalEnergies have decided to join forces to produce SAF. This project is a forward-thinking step towards creating a sustainable world for tomorrow.


Sustainable aviation fuel can be produced from biogenic residues such as used cooking oil and fats from animal by-products. Especially in the collection of animal by-products, local resources are used, with the material coming from local butchers and farms. After collection, the feedstock is pre-treated to remove impurities. It is then processed into SAF and blended with fossil jet fuel to be delivered to airports.

  • The starting material (used cooking oil and animal by-products) is collected and processed.

  • In a refinery, the processed material is converted into SAF.

  • Fossil jet fuel is blended with up to 50 % SAF.

  • The blended fuel is supplied to airports for refuelling aircrafts.

High quality product:

Since SAF is a so-called “drop-in“ fuel and can be used in existing aircraft, because it does not require new infrastructure or investments innew airplanes but is a sustainable switch that is available immediately.

Environmentally friendly:

SAF has the potential to reduce carbon emissions by up to 80 % compared to the conventional jet fuel it replaces. Therefore, it will make a significant contribution to the sustainable reduction of the industry’s carbon emissions.


Thanks to the higher energy density
of SAF than traditional jet fuel,
fuel efficiency can be increased by
1.5 to 3%. This not only increases
an aircraft’s range, but also reduces
its hourly fuel consumption figure.


As with biodiesel, the production of SAF does not compete with food processing if sustainable biogenic material such as non-edible animal fats and used cooking oils are reused. Another innovative way to recycle valuable residues.

Sustainable fuel for today and tomorrow

The production of SAF is the logical step to effectively push the climate movement in the field of air transport. The market for green aviation fuel is being boosted by legislative measures such as the EU’s ‘Fit for 55’ package, which sets EU members ambitious targets to reduce CO2 emissions. Starting 2025, it will be compulsory in the EU to have at least two percent of SAF in all the kerosene used, with the number increasing to five percent in 2030, and 20 percent in 2035. While over 40 airlines worldwide have used sustainable aviation fuel since 2019, 15 airports in Europe are currently supplied with SAF on an ongoing basis. And this is only the start of a new era in the air transport sector.
