Neste MY SAF
What many see as waste, Neste sees as valuable raw material
The renewable raw material inputs for SAF consist of waste and residue raw materials - like used cooking oil and animal fat waste.
The raw materials are pre-treated
The waste and residue materials are pre-treated to remove impurities. This creates a clean, pure raw material that can be turned into a high quality sustainable fuel.
Refining into SAF
SAF is made from hydrocarbon molecules through a process called hydrodeoxygenation. Oxygen originating from renewable raw materials is removed with the help of hydrogen. Other impurities, like sulphur and nitrogen, are also removed during this process. Hydrocarbons are then isomerized to fine-tune the properties of the end product into SAF. During this process, the hydrocarbon structure is branched to create the desired properties, a unique element of our proprietary NEXBTL™ technology. After the isomerization step is completed, further distillation is completed so that SAF fully meets ASTM 7566 requirements.
The end result is Neste MY Sustainable Aviation Fuel
Neste MY SAF is then blended with conventional jet fuel prior to use, as current ASTM specifications allow SAF to be blended up to 50%. It is then certified as a regular jet fuel and ready to be delivered to airports to fuel aircraft.
