In the future, passenger aircraft around the world will be able to use fuel extracted from sawdust or straw instead of gasoline as currently.
Over the past year, wood factories in Singapore have generated more than half a million tons of wood waste, mainly sawdust.
Scientists at the Center for Surface Chemistry and Catalysis (KU Leuven University, Belgium) say they have successfully converted sawdust into gasoline.
George Huber and colleagues at the University of Massachusetts, Amherst are working on converting sawdust and grass into gasoline.
