The production of bioethanol is however cumbered with problems both in the acquisition of biomass and its eventual processing to the final product. Pollution, water utilization and soil degradation are some of the major drawbacks in bioethanol development. Also, fossil fuels used in production, food versus fuel problems, coupled with conflicts in competing land use interests (Larsen, Johansen & Schramm 2009). Current ethanol production are associated with N2O a more potent greenhouse gas for this reason bringing into contention the potential of bioethanol in reducing greenhouse gases and the overall objective of controlling global warming. The land cultivated for feedstock, other than economically empowering farmers, improving infrastructure and technology is likely to increase cabondioxide emissions at a greater rate that outweighs the advantage of the bioethanol. Cheap feedstock’s and high energy efficiency crops are present trends in bioethanol production. Industries that previously did not utilize their waste materials are persistently using this waste for the production of ethanol.
Ethanol as fuel differs from gasoline based on properties. Ethanol is hygroscopic and prone to contamination by water, and this is further complicated by the fact that its production is favored by maintaining an optimal amount of water (Larsen, Johansen and Schramm 2009). Ethanol also has poor blending capabilities with both diesel and gasoline when it contains water and use of fuel containing some water is an issue. Problems with engine start have been reported in cold climates and also the inflammable and volatile properties of ethanol. Ethanol content in gasoline used for regular vehicles is limited up to 10% blend. However, there are vehicles ...Download file to see next pagesRead More

...?Ethanol Early history is full of documentation, even as early as 9,000 B.C., depicting how ancient people made and used ethanol as a psychoactive recreational drug. The fermentation of sugar into ethanol is one of the earliest known organic reactions created by mankind. Ethanol has been widely used by nearly every civilization and still continues to this day. Now, as the quest for a replacement for fossil fuels drives research, ethanol has taken a vital place in the energy needs of the future. Ethanol was not used as a fuel until Samuel Morey developed the first combustion engine in 1824; it ran on ethanol and turpentine. It was mostly used industrially and for lamps until 1862, when the U.S. Congress placed a $2 per gallon tax... on it to...

...Sur Supervisor Ethanol Fossil fuels have polluted our environment in last one hundred years or so leading to global warming and climate change. Of late many countries have promoted the use of alcohol as bio-fuel blending with fossil fuels in a certain ratio; however, promotion of ethanol as a bio-fuel is now highly questionable. Studies reveal that environmental impact of ethanol as bio-fuel is much higher than that of gasoline and other fossil fuels. The paper aims at exploring how ethanol is more damaging to our environment and its use as energy source cannot be encouraged. Flow diagram For E85 and Gasoline Source:...

Corn-based Ethanol Production

...Running Head: Quantitative Thesis Thesis Topic: An analysis of the impacts of corn-based ethanol production on the United s' corn price Chapter I Introduction The world is gravitating towards the accomplishments of the set goals for establishing a green world". U.S President George W Bush has maintained the emphasis on corn-based ethanol production in the core of his energy policy. The thrust has been spurred by the critical and adverse impact on global climate of heavy industrialisation which emits atmospherically hazardous gases into layers of the atmosphere, causing global warming. The growing corn-based ethanol production industry has laid...

Social Costs of Ethanol Production

...Consumer awareness of the social costs of ethanol production and how this knowledge affects public acceptance Introduction Owing to environmental pollution and running out of fossil fuels, such as coal and natural gas, biofuels are becoming the most suitable alternative. Even if it can solve the energy crisis, it is not without any harmful global effect that can be threatening to modern as well as future generations. Ethanol, known by Ethyl Alcohol, is the same chemical compound that is found in alcoholic beverages. It is an effective motor fuel, which is produced from agricultural crops, primarily corn, along with from other recycled wastes and residues. It is quite effective in reducing greenhouse...

Ethanol Alcohol

... 15 August Ethanol Alcohol Ethanol, the 2-carbon alcohol illustrates the attitude-changing impacts of the Alcohol Beverages. Ethanol alcohol is a carbohydrate that is a simple molecule which provides cells with energy when it is burned. The non-necessary nutrient Ethanol serves as a cellular toxin and an active drug before its metabolism commences. In the capacity of a brain drug, ethanol alcohol fully destroys the brain function just like an anaesthetic. It is responsible for the destruction of the alcoholics as members of the society. Ethanol alcohol is different from other liquids when consumed because it escapes the normal process of digestion and instead directly enters the blood stream. It is not thus converted for supply... to the...

Corn and Ethanol Prices

...Corn and Ethanol Prices Affiliation: The economy is made up of numerous sectors, all of which contribute to the total output of that economy. The agricultural sector is one of the primary sectors in an economy. Production in this sector significantly influences the productivity of other sectors in the same economy. This is due to the fact that the output of the agricultural sector is used an input in other sectors. The article "Feeling Parched" highlights the consequences of drought in the production of corn, and the subsequent economic effects posed that occurrence in the State of Lowa and beyond. Drought conditions in Lowa resulted in reduced corn output levels, posing significant threats to related activities that use...

The Effects of Ethanol Production

...The Effects of Ethanol Production Affiliation: The use of ethanol is broad in scope due to the myriad purposes that it serves across social and economic contexts. Programs have been designed, formulated, and implemented, encouraging the use of ethanol in the many fields that it can possibly serve. Expanding these programs can be beneficial enhancing the economic performance of the various sectors of the economy. These benefits can vary depending on the specific area of concern, but the common denominator is that users of ethanol stand a better chance to benefit than lose. As already highlighted, ethanol serves myriad purposes. They include, but are not...

Ethanol effect on kidney

...Both forms of ethanol consumption i.e. acute and chronic have the ability to seriously compromise kidney function, more specifically in juxtaposition with distortion of liver function. Various investigators have studied the alcohol related structural as well as functional changes in the kidney function along with the ability of ethanol to alter the regulation of the composition and the volume of fluids and electrolytes of the body (Curry 60). It has thus been concluded that patients having a considerable proportion of ethanol in their body may experience lower concentrations of various electrolytes in their blood stream. Therefore, chronic abuse of ethanol impairs the...
