Cellulosic ethanol is a so-called second generation biofuel made from cellulosic plant material, such as wood, grasses or corn husks.
Tougher cellulosic material had previously proved ineffective as a feed stock for biofuel, however, new developments in enzymes and other catalysts have proved effective at breaking down the organic material ready for being turned into biofuel.
Advocates of cellulosic ethanol argue that it is better for the environment
than traditional biofuels as it does not impact food supplies and requires less
produce than corn-based starch ethanol.
They also claim that it can deliver higher yields per acre as grasses or other cellulosic crops can produce more biofuel than corn, because the whole plant can be used instead of just the grain.
