Cellulosic ethanol has mass appeal due to its use of biomass (woods, grasses, non-edible plants) as feedstock. While the feedstocks are substantially cheaper than corn, the cost and processes of different acids and enzymes used have made it difficult to transition into mass production. There are two primary processes for producing cellulosic ethanol, Cellulolysis and Gasification. Both use the same feedstocks and generally produce the same outputs, with same variation on by-products based on the acids and enzymes used.
