Though we need to improve upon the methods, it seems to make sense to use plant waste rather than corn to produce ethanol.

I totally agree Ceetol (Cellulosic Ethanol) can be produced from plant waste - we have a lot of it - managed forests need to be cleaned (not of trees but of debris) so as to avoid forest fires - the dead debris creates a greater likelihood that a forest will go on fire. Lawn clippings and hedge trimmigs could be collected locally or diverted in municiple waste dumps for ethanol production rather then being left to rot, and the life-span of a municiple waste facility would be extended by up to 60% - Ceetol is a win-win ethanol solution.
