New Biofuel Shows Pollution-curbing Promise
Tests conducted by Rolls-Royce show the blend could burn more than 50-percent cleaner than straight jet-A.

Bio-fuel manufacturer Virent is touting the lower-particulate-matter aircraft engine emissions resulting from burning its BioForm Synthesized Aromatic Kerosene (SAK) fuel blend. According to the manufacturer, in FAA-sponsored tests performed by Rolls-Royce, jet fuels containing SAK reduced particulate emissions by more than 50 percent compared with conventional jet fuel.
