$GEVO "Gevo has been producing and selling its patented alcohol-to-jet fuel (ATJ) derived from isobutanol since 2011. Gevo is working toward further commercializing its patented ATJ, which is a clean burning, homegrown, drop-in jet fuel that has the potential to deliver aviation biofuels at scale and at competitive cost. Fossil-based jet fuel is one of the largest expenses for airlines. Gevo’s ATJ is expected to help reduce the airline industry’s carbon footprint and help control fuel costs." http://www.gevo.com/our-markets/jet-fuel/
