​​ASTM International’s energizing fuels division recently passed an Alcohol To Jet (ATJ) ethanol based specification ballot measure that will allow jet fuel, produced from ethanol under the ATJ process, to be sold commercially on a global basis.  ASTM D7566 had previously permitted ethanol as a feedstock for Aviation Turbine Fuel with a maximum final fuel blend of 50 percent, but now permits a full replacement of the hydrocarbon fuel. This change opens the door to the use of more drop-in fuels used as alternatives to fossil fuels.  Kevin Weiss, CEO of Byogy Renewables, stated of the change, "it's one thing to have a great commodity product, but without an operative supply chain it's difficult to sell. […] We now have the ability to supplement and leverage the existing downstream petroleum industry with a well distributed ATJ Sustainable Aviation Fuel that can be produced anywhere by building on the existing global ethanol supply chain.”
