b'FUELINGTRK 47SAF 101Neste MY Sustainable Aviation Fuel (SAF) is made from sustainablyproduction technology in the sector, and most of the SAF produced sourced, 100% renewable waste and residue materials, such astoday is HEFA SAF. used cooking oil and animal fat waste sourced from around the Nestes production process has several steps. After waste and world.residue materials are collected, they are pre-treated to remove In the United States alone, the companys subsidiaries collectimpurities to improve the quality of the final product. The fuel itself used cooking oil from more than 80,000 restaurants. is made from hydrocarbon molecules through a process called The fuel is manufactured at refineries throughout the world andhydrodeoxygenation. During the refining process, the raw materials then shipped to one of the companys blending terminal in California.are broken down to molecular level and rebuilt as fuel molecules:Per ASTM jet fuel specifications, it can be blended up to 50% withOxygen originating from renewable raw materials is removed conventional jet fuel. After blending, it is certified and transported forwith the help of hydrogen. Other impurities, such as sulphur and delivery via ships or trucks.nitrogen, are also removed during this process. Neste uses its proprietary NEXBTLHydrocarbons are then isomerized to fine-tune the properties of technology to produce SAF. This is based onthe end product into SAF. Hydrotreated Esters and Fatty Acids (HEFA) After the isomerization step is completed, further distillation is technology, and is one of only seven ASTM- completed so the resulting product fully meets ASTM-D7566 approved pathways to produce SAF. Michaelrequirements.Sargeant, vice president Americas for NestesNeste supplies a growing volume of SAF to airports in California, Renewable Aviation Business Unit, notes thatincluding San Francisco International (SFO) and Los Angeles HEFA is currently the most commercially viableMICHAEL SARGEANT International (LAX).
