Boeing has completed the world’s first flight using “green diesel,” a sustainable biofuel made from vegetable oils, waste cooking oil and waste animal fats. The company powered its ecoDemonstrator 787 flight test airplane on Tuesday with a blend of 15 percent green diesel and 85 percent petroleum jet fuel in the left engine.
