Advanced biofuels face uncertain future

The delay in proposed renewable fuel minimums by the Environmental Protection Agency may have hindered the future of advanced biofuels, the kind of cellulosic ethanol formulas made from tall grasses and stalks. Although researchers tout advanced biofuels' environmental benefits, the uncertain policy has caused some in the agriculture industry to shy away from them.

The Environmental Protection Agency proposed to cut 3.75 billion gallons of corn-based ethanol from original 2014 through 2016 Clean Air Act standards.
