Ethanol comes from a variety of bio-mass. The most commonly used sources include soy, corn, wheat, sorghum, grass, potato skins, rice, barley, sugarcane, switchgrass, palm-oil, wood and straw. Rarely, other kinds of plant-matter may be used, but even rarer is using recycled restaurant greases and animal fat (Renewable Fuels, 2007; Ethanol, a Biofuel, n.d.; Cellulosic Ethanol, 2007). This will be focusing on the ways to make cellulosic ethanol, or ethanol obtained from cellulose.
