It is evident that ethanol as a fuel is more economically viable and safe. However it is also 20-30 cents more expensive to make per litre to the petroleum alternative, large amounts of arable lands would need to be devoted to growing suitable crops with consequent problems of soil erosion, deforestation, fertiliser runoff and salinity to obtain the ethanol. Leading to assassinated land degradation problems in the manner of soil erosion and the reality of this deforestation of rainforest leading and contributing to an offset of greenhouse reductions, and although less evident than the endless pumps of an oilfield, all these square kilometres of monoculture will have a disastrous effect on biodiversity. Not only will animals and agriculture be affected by this but this prodigious use of the vital resources of grain, land and water in the production of Ethanol, will not only offset CO2 reduction but strip undeveloped countries of food sources contributing to famine and even death of starvation and malnutrition. Thus if we truly desire to use ethanol as an alternative, we must move to obtain the raw material for ethanol production from waste cellulose, which has been previously harvested for their food sources, rather than fresh corn or sugarcane.Potential future methods of ethanol production:To prevent famine and deforestation to produce the starch, sugars and cellulose to ferment ethanol, we as a society need a feasible future method, one that doesn’t rely on current sources and offsets CO2 reduction by furthering the environmental of deforestation. One way to do this to develop processes to turn garbage and plant material into fuel. Researchers are exploring ways to make ethanol from other feedstocks or plant materials. Feedstocks are also known as biomass and include corn stover (leaves and stalks of the corn plant), corncobs, and wheat straw, perennial grasses, wood chips (including waste from the forestry and paper industries), and debris from food manufacturing. Waste from our communities such as garbage, shredded paper, and wood waste are also being considered. Researchers from around the world are evaluating plant materials that grow in their region for cellulosic ethanol production potential. Merely comparing and researching what sources of ethanol are the most efficient and viable will be pivotal to the future methods of production statistics from https://web.extension.illinois.edu/ethanol/cellulosic.cfm stated that for every acre of corn between 420-840 gallons of ethanol can be produced in comparison to one acre of grass that provides between 150-1200 gallons of ethanol. Advancements in distillation processes and research into developing higher-yielding enzymes instead of zymase will play the most pivotal role in the future of ethanol production methods.
