A biofuel is a renewable fuel that is produced from vegetable and animal fats. The process that converts these oils into fuel is known as transesterification or esterification. in transesterification, the fatty acids and triglycerides that are within animal and vegetable oils react with methanol with a catalyst such as sodium hydroxide which results in the formation of fatty acid methyl esters. Structurally, both biodiesel and petrodiesel contain hydrogen and carbon atoms, however petrodiesel is a pure hydrocarbon compound whereas biodiesel has two oxygen atoms, an ester group (Goshen.edu). Biodiesel differs from petroleum as environmentally, as biodiesel is biodegradable and non-toxic, and is more environmentally friendly compared to conventional diesel which is considered to be an environmental hazard as it is not renewable and contributes to the weakening of the ozone layer and global warming due to its carbon, sulphurous and nitrogenous dioxides, due to incomplete combustion. Biofuels can be a progressive move in society due to its environmental benefits in reducing harmful emissions into the atmosphere, however the fuel does require more processes to be converted to fuel and by using food crops as a possible biofuel source, this could create a shortage in crops. However, by making biofuels the prominent fuel, more jobs could be created which would be beneficial economically but biofuels are more expensive to produce and purchase than normal petrodiesel so if
A major source of controversy when it comes to biodiesel and other biofuels such as ethanol is what ingredient are used to make the fuel. When oils from crops are used, a number of problems can arise. For instance, biodiesel and other biofuels are often touted as environmentally friendly since they are typically made from plants, which suck the global warming gas carbon dioxide from the atmosphere to grow. However, the land may be damaged in order to grow these crops as demand for biofuels grow for example, in Indonesia, biodiesel may be causing deforestation, as native forests are destroyed to make way for palm oil plantations, according to the Union of Concerned Scientists. The chemicals from agricultural fertilizers and pesticides may also upset ecosystems.
Jamestown is thought by most of to be the first colony in the New World but this is not the complete truth. Jamestown is considered our first successful colony; however it was not the first attempt at a colony. There were a few attempts to colonize the New World before Jamestown and one in particular that was the most mysterious is the Roanoke colony, also known as the Lost Colony. The colony got this name because the colonists that were there vanished mysteriously with no trace of what happened.
Due to the ever-growing transportation needs, humans have used biological processes to produce biofuels. Biofuels, are fuels that are those produced from biological processes rather than geological processes. They are considered a form of renewable and clean energy. Celluloses are used to break down cellulose into simple sugars such as glucose, which later on using fermentation are converted to
Nowadays, biofuels have become essential for future economic development and environmental protection. Primarily, their environment-friendliness and low carbon emissions are emphasized as the main advantages. However, in reality, few investigations were made to find out the disadvantages of such renewable alternative, and it may bring much more negative impacts than its advantages.
“All Biofuels Are Not Created Equal” is a very informative article that everyone should be aware of. The authors of this article show how biofuels can be made to benefit Earth. Our ecological footprint is so big that everyone requires 2.5 Earths to maintain the same lifestyle. What does this reveal? It reveals that Earth’s resources are being diminished. This means that the world needs to do something to prevent this so Earth can last for future generations. The way that biofuels are being made is not very effective in helping this problem. This is because it either requires deforestation or the burning of fossil fuels, which the world is trying to stop. Instead of using corn or sugar cane as ethanol, alternative crops should be used
1.0 IntroductionBiodiesel is defined as mono-alky esters of long -chain fatty acid. It is a fuel that derived from the vegetable oils, animal fats, which is similar to the diesel fuel except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for
When researching the effects of biodiesel versus vegetable oil on a vehicle the results were interesting. Due to the increasing gas prices and the Obama Administration to wean the U.S. off of the addiction of oil, people are starting to switch to alternative fuel. ("Diesel vs. Biodiesel vs. Vegetable Oil | Homegrown Fuels - Consumer Reports." Diesel vs. Biodiesel vs. Vegetable Oil | Homegrown Fuels - Consumer Reports. N.p., n.d. Web. 09 Dec. 2014.) this would include farm crop and renewable organic material. they are also in use with biodiesel and Vegetable oils. Developed from vegetable or animal fats, biodiesel is functionally identical to petroleum diesel. Adherents claim it pollutes much less than regular diesel. A relative of biodiesel is plain, edible cooking oil. Because it's not financially practical to fuel a car with cooking oil from grocery store shelves— a
Biofuel can be used as substitutes for conventional fuels e.g. petro fuels. Mainly, biofuel contains hydrogen and methane which are particularly
Family planning is one thing that any family should consider for its survival in the near future. Most of the people might ignore it but at the end it will carry a lot and affect the family relations. The effect might be carried for so long time down the road. Birth controls are matters that should be taken seriously by the couple in a relationship.
Biodiesel was synthesized in order In lab 6, the toxicity of the biofuels was measured to determine which fuel was most toxic and degrading for human life. The toxicity level of each fuel is extremely important in determining which biodiesel is most suitable for the environment since Life . A form of measurement of toxicity is the LD50 or the amount f a toxic agent that is sufficient to kill 50 percent of the population of animals usually within a certain time.* The toxicity will vary depending on the size The data measured from the toxicity of each biofuel will determine which is most suitable.The amount of biofuel and . Though the germination of a set number of radish seeds with a fixed concentration of biofuel a determination of which one is most lethal for life was determined. In lab 7, the viscosity of the biofuels were determine to see which one would be most efficient for modern machinery use and . The more viscous a solution is, the faster it will travel to start an engine. This makes a care more efficient because it takes less energy to start and will
When it comes to the environmental issues that surrounds the use of biofuels. Biodiesel contains less amount of sulfur. An example of this will be that they are carbon neutral which is the amount of carbon dioxide released when the issue is that the same amount is absorbed by the plants as they grew and if this happens that this would reduce the production of this greenhouse gas. Thus while biofuels produce less carbon dioxide overall thus there are no results for the production of carbon neutral, the result is that fossil fuels are used in their production, an example is the making of fertilisers for growing plants. Biodiesel production is the process of producing the biofuels, biodiesel through the chemical
In the ultra-connected multi-tasking modern world, it is normal to get bogged down from time to time. Dark moods and periods of sadness are a normal part of life and depression is often a term used to describe such periodic doldrums. However, clinical depression is a more complicated and serious matter. If you think you or a loved one may be dealing with depression, recognizing and understanding the symptoms is a great first step toward finding treatment.
In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.
To date, when issues related to environment, GHG(Green House Gas), sustainability are gradually concerned, increasing people is pursuing new ways to lower down the negative effect exerted by modern industry. This also attracts government’s attention upon encouraging utilization and production of alternative energy and offering financial aid for some newly high-tech companies. One solution to deal with this global concern is finding or develop alternate fuels to replace the fossil fuels such as biofuels. The utilization of biofuels as energy for transportation is mainly driven by the over-depletion of oil, the concerns about energy consumption and the emission of Green House gas. However due to some barriers, the most recently used biofuels will replace around 10% to 15 % of fossil fuels in the field of transportation[2]. The merits and demerits of adopting corn Stover as a feedstock to produce biobutanol, bioethanol and biodiesel[2] as well as diesel, soybean biodiesel, gasoline and corn ethanol are studied based upon LCA[3](Life Cycle Assessment), a new method to analyze the influence of the ecosystem output in the life cycle. LCA is commonly used for measuring environmental influences of a product system, including different life cycle period[4] and [5].
To answer the call of this crisis, the world may turn to other energy sources like biofuels, which are a relatively developed, yet innovative alternative to fossil fuels. Biofuel is a cleaner and renewable source of fuel that is able to combat fossil fuel price increases in relation to the limiting supply of fossil fuels with many existing and currently developing biofuel technologies to lower greenhouse gas emission and environmental damage. Biofuel technology derives from organic biomass which may include trees, grasses, plants and aquatic plants. From the photosynthesis of these biomass materials, plants convert carbon dioxide (CO2) and water into carbohydrates (simple sugars) and lignocellulose.
