Biofuels are alternative sources of energy that are produced from living organisms or their metabolic by-products. These fuels have gained increasing attention in recent years as a way to reduce our dependence on fossil fuels and mitigate climate change. In this essay, we will explore the various types of biofuels, their production methods, and the advantages and disadvantages of using biofuels as an energy source.
There are several different types of biofuels, each with its own unique characteristics and production methods. Ethanol, for example, is a type of biofuel that is produced from plant materials such as corn, wheat, and sugarcane. It is commonly blended with gasoline to create a fuel that can be used in traditional gasoline engines. Biodiesel, on the other hand, is a biofuel that is produced from vegetable oils or animal fats and can be used as a substitute for diesel fuel.
Biofuels can be produced through a variety of methods, including fermentation, thermochemical conversion, and biochemical conversion. Fermentation is the process by which sugars in plant material are converted into ethanol through the action of microorganisms. Thermochemical conversion involves the use of heat, pressure, and catalysts to convert plant material into biofuels such as bio-oil and biochar. Biochemical conversion refers to the use of enzymes or microorganisms to convert plant material into biofuels.
One of the main advantages of biofuels is their potential to reduce greenhouse gas emissions. Biofuels are considered to be more environmentally friendly than fossil fuels because they are derived from renewable resources and their carbon emissions are offset by the carbon dioxide absorbed by the plants during their growth. In addition, the use of biofuels can help to reduce our reliance on fossil fuels, which are a finite resource and contribute to climate change through their greenhouse gas emissions.
However, there are also several disadvantages to using biofuels as an energy source. One major concern is the potential impact on food security. The production of biofuels often involves the use of crops that could otherwise be used for food, leading to competition for land and resources. In addition, the production of biofuels can have negative impacts on the environment, such as deforestation and soil degradation. Finally, the production of some biofuels can be energy-intensive, potentially offsetting some of their environmental benefits.
In conclusion, biofuels offer an alternative to fossil fuels that has the potential to reduce greenhouse gas emissions and reduce our reliance on fossil fuels. However, there are also significant challenges to the widespread adoption of biofuels, including their impact on food security and the environment. Further research and development is needed to address these challenges and maximize the potential benefits of biofuels as an energy source.
Biofuel Argumentative Essay
Water required to grow these crops as well manufacture the fuel is massive. The production of bio-fuels crops increases the competition in land utilization among food crops and bio-fuels feedstock. The use of forests and farms in bioenergy helps get rid of the harmful release of carbon dioxide and achieve a balance. Biofuels: For Better or For Worse? The sources used in production are mostly food crops. Powering The Future of Flight , 1-20.
Environmental Protection Agency EPA was founded as well as the first Earth Day. The product produced from this hydrolysis is then neutralised and fermented to produce ethanol. Thereby, the huge subsidization of bio-fuels tends to give higher priority to bio-fuels rather than foods. Position papers include more opinions than proposals. Biofuel Types Table This table explains the feedstock used for the different biofuel types, also what is the production method and applications of each type. Agriculture is an area that is constantly developing, and new ways of recycling waste and other raw materials are regularly invented. However, current societies are still dependent on fossil fuels.
These guidelines are provided by the concerned faculty in an effort to provide better understanding of Biofuels in a larger extent. Cellulose comprises about 33 percent of all plant matter, 90 percent of cotton is composed of cellulose and so is around 50 percent of wood Britannica encyclopaedia, 2008. In short these are resources that can be finished, output exceeds input, and they are infinite. For example, British Petroleum have donated half a billion dollars to US institutions to develop new sources of energy — primarily biofuel crops Sticklen, 2008. In the case of second generation, bio-fuels are manufactured from plant lingo-cellulosic materials. A positive impact is on the environment due to a reduction in the number of harmful emissions.
Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. It depends on how they are manufactured. Analysis of termite guts found to produce cellulose, ligninase, xylanase and keratinase in greater number. Gasification Fermentation Hydrogen contains an energy density of 123 Used in place of the hydrogen produced from fossil fuels Cellulose It is made from wood, grass, or inedible parts of plants 1. Many cell wall deconstructing enzymes have been isolated and characterised and more need to be investigated for finding more enzymes that can resist higher conversion temperatures and a range of pHs during pretreatment.
Acting on this belief the US government is planning on turning enough food into fuel by 2022 that could feed half the population of the United States! What can they do? Today, Germany is the top leading Thesis Statement For Informative Essay Informative essay thesis statement: Nowadays, biofuels have become essential for future economic development and environmental protection. Monsanto Argument Paper 1537 Words 7 Pages Monsanto was founded in 1901 in St. It is considered eco-friendly and benefits the environment because it releases an amount of carbon that is similar to the amount of carbon that the organic matter used to produce it absorbed while it grew so it balances the carbon of the atmosphere. The advantage of first generation biofuel is… References Amani, E. The primary structure of cellulose as shown in figure 2, is a linear homopolymer of glucose residues having theDconfiguration and connected byß- 1-4 glycosidic linkages Sun et al, 2009.
Humanity had never seen a more compatible source in which came a higher demand for oil. All auto Palm Oil Thesis Statement 703 Words 3 Pages Nebila Ahmed October 21, 2016 Outline Thesis statement: Although the production of palm oil is economically beneficial for Indonesia, palm oil production has led to the deforestation of rainforests and habitat loss for rare and endangered species such as the Sumatran tigers, Komodo dragons, Sumatran rhinoceros, Javan elephants, Bornean Orangutans, and Sumatran Orangutans. Gasoline is very expensive today, and using the energy that is used to power our home, is much less expensive and more available than gas. . One of the directions of modern engineering is the use of biofuel.
The commercial and military sectors end up lacking enough bio-fuel produced energy. Cellulose from different sources also varies in chain lengths, for e. With the mass production of bioethanol, the production costs will further decline which will serve as The United States consumes 7 billion of petroleum yearly, and many small companies are beginning to produce bioethnol due to the tax subsidies they enjoy, which makes the venture to be economically visible. Throughout this article several statistics are given to show how energetically unfavorable the production of biofuels really is. However, there have been several claims against Monsanto and its use of harmful GMOs.
They have asserted that although bio-fuels are clean while burning, the processes involved in production, including the equipment used in cultivation of crops produce heavy carbon emissions. It produces the highest amount of carbon dioxide when burned than fuels like methane. Another importance of this study is that it will contribute to the body of knowledge on the method to use locust guts for the mass production of biofuels. The concern for preserving diesel fuels stems from its non-renewal in nature; however, the racing industry should not be forced to use biofuels because of three primary reasons — performance, cost effectiveness and high infrastructure expenditure. By using the genetic information from one organism, and inserting or modifying it into another organism, scientists can make food crops stay fresher, grow bigger, and have the crops create their own pesticides.
One way of decreasing such costs is to produce these enzymes within crop biomass. In the future, this method can become a common working strategy of oil engineering and help companies to improve their efficiency while reducing costs. Global prospects for the biofuels industry. Presently, two methods are widely used for cellulose degradation on an industrial scale: Chemical hydrolysis: This is a traditional method in which, cellulose is broken down by the action of an acid, dilute and concentrated both acids can be used by varying the temperature and the pH accordingly. Two other important and related areas for further research are increasing the levels of production and the biological activity of the heterologous enzymes Sticklen, 2008. Some gas stations Pros And Cons Of Biofuels one way to do just that.
These cellulose molecules consist of long chains of sugar molecules. You will be able to confidently write your own paper on the influence of biofuel on various aspects of life, reflect on the importance of biofuel, and much more. Bio-fuels crops are eighty percent of the total operating cost of bio-fuels Demirbas, 2009. A general challenge is to develop efficient systems for the genetic transformation of plant systems for the production of cellulose degrading enzymes. It emits carbon or greenhouse gases in meager quantities. More than 95 percent of gasoline sold in the United States contains ethanol.
