 Cellulosic ethanol can be produced from a diverse array of feedstocks, such as wood pulp from trees or any plant matter.Instead of taking the grain from wheat and grinding that down to get starch and gluten, then taking the starch, cellulosic ethanol production involves the use of the whole crop.This approach should increase yields and reduce the carbon footprint because the amount of energy-intensive fertilisers and fungicides will remain the same, for a higher output of usable material.
