Representatives from companies that produce advanced biofuels, including DuPont and POET, announced September 5 that they are close to achieving commercial scale production of cellulosic ethanol and that they expect production of cellulosic biofuel to increase substantially next year as biorefineries in the planning and construction stages go online. The statements conflict with criticism of the inability to meet biofuels use mandates in the renewable fuels standard due to missed production targets and this year’s drought.
