Disadvantages Of Biodiesel

The world has seen fuel prices spiral up or down to meet supply and demand. Because of this, people need to choose a cost effective fuel to meet their needs. Vehicles in the world today run off of many different types of fuel. Biodiesel is a modern fuel compared to the commonly known diesel. Biodiesel has several advantages over diesel. Biodiesel fuel comes from a renewable resource, it is better on the environment, and it meets the Environmental Protection Agency’s definition for fuel standards. In addition, Biodiesel is the most promising alternative fuel source, backed by both federal approval and incentives. Finally, consumer attitudes are changing for the positive when it comes to biodiesel. For these reasons, biodiesel should be used more often by people in the world today.

Since biodiesel is made entirely from vegetable oil or animal fats, it is renewable and biodegradable. Biodiesel also contains very little sulfur, polycyclic aromatic hydrocarbons, and metals. Petroleum-derived diesel fuels can contain up to 20% polycyclic aromatic hydrocarbons. For an equivalent number of carbon atoms, polycyclic aromatic hydrocarbons are up to three orders of magnitude more soluble in water than straight chain aliphatics.

Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)

Anything containing oil has been an increasing problem to the environment and to people. The toxicants that the oil produce harms people with their health. In the film Fuel, the director Josh Tickell talks about how crops can produce fuel, which produces cleaner air and is safer for the public. There are also other ways that Biofuel could be produced, such as adding human waste onto algae. The way that society utilizes oil is hurting the world, which in fact is affecting the human population and environment, but people only realize it until it is too late. With biofuel people would not be in danger and it could be produced without struggling to find oil.

Bio diesel is good for the economy because it is a fuel which can be created from locally available resources such as vegetable oils, coffee grounds, and animal fats. Biodiesel production and use

I believe this switch is vital to our future. With gasoline prices volatile and the Obama administration committed to easing the United States ' addiction to oil, many Americans seem to be taking more interest in pursuing alternative fuels. These alternative fuels include those derived from farm crops and other renewable organic sources. Among the most widely available are biodiesel and vegetable oil, both of which can be used to power a diesel engine.

Initial research has shown that biodiesel, liter for liter, generates about 90 percent of the heat of traditional fossil fuels, and the resulting air emissions are significantly lower in sulphur, carbon monoxide, and hydrocarbons. Burning these fuels also does not contribute to global warming. Fossil fuels increase the amount of carbon in the atmosphere because the carbon they release upon combustion has been locked away for millennia. The carbon released by the combustion of biodiesel first had to be removed from the atmosphere by the plant that produced the oils it was derived from. Thus, no net gain occurs when said carbon is released. Biodiesel is also safer for people and the environment since it is non-toxic and biodegradable. Oil spills will no longer be multi-million dollar environmental catastrophes.

[4] Biodiesel is another possible alternative. It can be produced from vegetable oils, animal fats, and recycled restaurant grease. Some of its advantages are that it is biodegradable, is generally safer to handle and it produces significantly less carbon dioxide emissions (up to 15% less). However, it too has problems. Similar to ethanol fuels, it has a lower energy content, which results in lesser MPG for cars. Fuels that contain a high percentage of biodiesel are also not

To solve the rigorous threat to earth from global warming, bio-fuels serve as the most feasible source of energy all over the world. The environmental and economical performance of bio-fuel as compared to fossil fuel was analyzed by full Life Cycle Analyses (LCA) in Spain. The Spanish government CIEMAT, carried out two LCA’s so as to compare ethanol-ethanol mixtures with gasoline, and biodiesel-biodiesel mixtures with fuel oil according to ISO 14040-43 standards, these standards evaluate energy and mass balance for two or more objects. It was concluded that carbon dioxide emission during utilization of bio-fuel are lower than fossil fuel and bio-fuel requires less primary energy to be processed than fossil fuels. Bob Dinneen, President and CEO of the Renewable Fuels Association submitted the letter to the editor of The Gazette in which he marked that “On an environmental level, conventional ethanol is reducing greenhouse gas emissions by 34% compared to petroleum, including hypothetical land use change emissions” (qtd. in renewable fuel association). As the raw material for

For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.

Biobutanol is a more feasible alternative to gasoline. It is a more viable motor fuel substitute to gasoline, as biomass – from which biobutanol is derived from – is readily available for production and more importantly is a renewable resource. Gasoline is a crude oil product derived from petroleum, which is finite and unsustainable as a motor fuel, because it is increasingly being used up faster than it is being produced. It is expected that with continued research, biobutanol could eventually surpass gasoline as the primary motor fuel. Evidence proves that biobutanol is more acceptable environmentally than gasoline and conveniently, biomass is readily available for the steady production of biobutanol. Biobutanol is more advantageous

Both biodiesel and ethanol are derivatives of biomass that have been processed to create a liquid biofuel. Both types of biofuels have been touted as secure and environmentally safe alternatives to fossil fuels, however the research verifying these claims is extensive but often contradicting. In the following paper, the efficiency and quality of the two types of biofuel will be discussed. The effects of variables such as source materials and production techniques on efficiency and quality will be considered. Due to the limited scope of this paper however, only generalized net analyses of ethanol and biodiesel production will be considered. The production of ethanol requires one of two source materials, cellulose

Due to high fuel prices, the society wants to get as much mileage as possible. Hence the higher mileage of biobutanol, will be apt for the current society. If the usage of fossil fuel was to continue, then reserves will be depleted in 50 to 120 years. Without transportation, the whole community infrastructure will be disrupted heavily. Thus, the urge to find new transportation fuel, has never been so high. Almost all household has at least one car, as from 40% of the population having a car in 1942, now 90% does. Also due to the vastly increasing population, more fuel is going to be required to be sufficient for the society’s energy needs. Petrol isn’t a sustainable resource as it is decreasing and isn’t renewable. So by using biobutanol, the energy needs of the future society can be maintained. As it is renewable, it will support the growing population and reduce the damage to the environment, as it reduces the amount of Carbon dioxide in the

Biodiesel is a renewable, biodegradable fuel that is recycled from vegetable oils, animal fats, and restaurant grease. Used to replace petroleum diesel fuel by its clean burning. It is a liquid fuel often known as B100 or neat biodiesel in its pure, unblended form. It is used to fuel compression-ignition engines like petroleum diesel. Both biodiesel and petroleum have compounds that crystallize in very cold weather. To prevent this, fuel blenders and suppliers use cold flow improvers.

This essay focuses on two renewable energy resources. First of all, biofuel is now accepted as alternative energy in worldwide. The figures continue upward trend in the biofuel production. ‘An annual growth rate of 6.8% from 2006 to 2030 is expected for total biofuels consumption in the transport sector’ (International Energy Agency: 2008 cited in Zhou, et al., 2009:S11). Significant leaders of the biofuel market are Brazil, the United States and the European Union. The results of research indicated that 92% of the world’s ethanol is produced by Brazil and US together, while 90% of the world’s biodiesel manufactured by the EU. In addition, several developing countries in Asia such as Indonesia, Malaysia, Thailand, and the Philippines have an enormous potential for biofuel production. Now these countries are
