Renewable fuels can now be blended with conventional commercial and military jet, or gas turbine, fuel through requirements in the newly issued edition of ASTM D7566-11, Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons. Through the new provisions included in ASTM D7566, up to 50% bioderived synthetic blending components can be added to conventional jet fuel. These renewable fuel components are identical to hydrocarbons found in jet fuel, but come from vegetable oil-containing feedstocks such as algae, camelina or jatropha, or from animal fats called tallow.''
