Consequently, the use of corn, sugarcane, or soybeans to produce biofuels causes considerable rise in prices for these crops. This scenario would trigger expansion of the corn fields to cover wildlife and other conservation areas. The expansion of such fields may contribute to an increase in carbon emission or other harmful gases such as nitrous oxide and methane when sugarcane fields are burnt. In contrast, production of cellulose requires considerably less space and efforts. This is precisely because it requires different raw materials that comprise use of byproducts from other production processes and cellulose energy sources from nature.
As compared with sugarcane, cellulose can produce the same amount of ethanol per acre as sugarcane, which is more than what corn produces. For instance, the amount of biofuel from produced from an acre of sugarcane is estimated to be 19,000 liters per year as compared to one acre of corn that produces 1,135 liters per year. Cellulose and sugarcane are estimated to produce equal amount of biofuel per acre (Bourne 2007). Hence, considering all the factors, the use of cellulose to produce biofuel is far better than the use of sugarcane and corn.
