Some biofuel crops, such as corn and sugarcane, are considered to be high-input crops not only when it comes to water demand but even when it comes to the use of pesticides to protect them against insects, weeds, and diseases. Although the creation of biofuels produces carbon dioxide as a byproduct, it is often used to grow the plants that are converted into fuel. Biofuels are renewable. A study in 2005 showed that using available farming and production technologies, from 27 to 118 percent more energy is needed to produce a gallon of biodiesel than the energy existing in it. Typically, garbage collection has certain disadvantages: Garbage collection consumes computing resources in deciding what memory is to be freed, reconstructing facts that may have been known to the programmer. Biofuel can be produced from plants or commercial, agricultural, domestic, or industrial wastes with a biological origin. The production and use of biofuels generates significantly less greenhouse gas emissions than the production and use of highly polluting fossil fuels. Second, the oil produced by these plants is not identical. Future Price Growth 8. According to studies, the levels of carbon dioxide emissions and particulate matter are reduced with biofuels, however, the nitrogen oxides are slightly higher than at fossil fuels [1]. (Dec. 11, 2010)http://www.extension.umn.edu/distribution/horticulture/dg2923.html, Rosenthal, Elisabeth. The garbage to biofuel process is not only an alternative way to produce home . Had it been the season's popular strain of corn, there could have been an ecological disaster as monarchs migrated through the corn-heavy American Midwest [source: Mellon and Rissler]. What are the disadvantages of biofuels? The green biomass from these grasses can be harvested regularly for the use as a biofuel. Some of these chemicals, which are mostly related to the combustion of non-biomass materials in garbage, can be hazardous to people and the environment if they are not properly controlled. While local crops have reduced the countrys dependence on fossil fuels, some experts believe it will take a long time to solve the energy needs. Its lubricating properties are significantly better. "E85 Vs Conventional Gasoline - Tech Knowledge." Disadvantages of Waste Management: We have now seen the merits of waste management in detail. Disadvantages of Biofuels 1. Syngas is a mix of carbon monoxide, hydrogen, and other hydrocarbons, which is produced by partial combustion of biomass. Moisture is more likely to be absorbed by biofuels than fossil diesel, which causes problems in cold weather. Though ethanol and other biofuels are often promoted as clean, low-cost alternatives to gasoline, industrial corn and soy farming still have a harmful impact on the environment, just in a. Compared with making ethanol from crops, the environmental benefits of making it from waste are clear: It diminishes the demand for landfills and cuts greenhouse gas emissions. This means they require more space to store the same amount of energy than fossil fuels. What are the economic drawbacks of using biofuels. Please refer to the appropriate style manual or other sources if you have any questions. During initial tests of a modified strain of corn, researchers discovered that the crop, which had been engineered to fight off a moth known to prey on corn, produced pollen that could possibly kill larvae of the monarch butterfly. Soil, groundwater and air pollution. Easier availability of biomass, its low cost, and cheaper technologies involved mean producing bioenergy is cheaper when compared to most energy sources, especially fossil fuels. The oil in their grains is pressed out, filtered, and reformed to fuel by a chemical process. Most of the waste generated worldwide is biodegradable. April 14, 2009. 2. Land use change leads to the loss of biodiversity, especially in many places where native ecosystems were previously untouched, as well as increased greenhouse gas emissions from the conversion of carbon-rich ecosystems. Biofuels are a more. For example, emphasis on ethanol derived from corn is shifting grasslands and brushlands to corn monocultures, and emphasis on biodiesel is bringing down ancient tropical forests to make way for oil palm plantations. Biofuels are generally of two categories: gaseous biofuel and liquid biofuel. It's Not Completely Clean High Costs In Comparison To Other Alternatives Possible Deforestation Production Requires Space It Requires Water It Has Inefficiencies It's Under Development All rights reserved. But it is even more economical solution in terms of paying a cost set by international political agreements. DISADVANTAGES OF BIOETHANOL 1. A way to reduce the impact of greenhouse gases is to use biofuels around the world. Brazil and the United States are among the leading producers of ethanol. The simple economic system of supply and demand of biofuels increases the demand for corn, for example, and it becomes more expensive. Web. This difference has an effect on the oils' viability as fuel. In this regard, cellulosic biomass is considered to be more beneficial. Disadvantages of Biofuels Despite the benefits, there are some disadvantages of biofuels that make the general population hesitant to use them. Disadvantages of Composting If the composted materials contain waste types such as animal or food waste there is a risk that diseases (for example "foot and mouth") may be spread in the compost. Perhaps the simplest drawback of biofuels is that it is not petroleum-based fuel so that they will work differently in engines developed for petroleum-based fuel. A Lack of Food 5. And once the engine's running, the differences in combustion properties between gasoline and ethanol means that the ethanol-converted engine needs to have its ignition timing adjusted to operate properly [source: Tsuneishi]. Let us know if you liked this article. Biogas and syngas are two types of gaseous biofuels. Biodiesel is less efficient than gasoline Biomass: Should we focus on more eco-friendly renewable energy? Discover world-changing science. Compared to fossil fuels, biofuels are considered to be a more environmentally friendly and sustainable energy source due to their renewability and lower emissions of greenhouse gases during burning. Biofuels are considered carbon neutral because the carbon dioxide emitted when they are burned is offset by the carbon dioxide that was absorbed by the plants during photosynthesis. The production of biofuels often leads to land use changes, such as the conversion of natural habitats to cropland. Diverting that waste to anaerobic digestion would turn a cost into an opportunity, generating revenue from energy production and co-products. It isn't as effective a fuel as traditional gasoline. Biodiesel, as the most common biofuel in Europe, is generated from oils or fats using transesterification. However, fuel ethanol contains denaturants to make fuel ethanol undrinkable. This is not the selective breeding they have followed for years; genetically modified crops are developed in the laboratory to tolerate herbicides better, fight off pests, and higher yields. Some algal species contain up to 40 percent lipids by weight, which can be converted into biodiesel or synthetic petroleum. The symbols of agricultural success in many parts of the world are endless fields of corn, soybeans or wheat, with identical crops stretching as far as the eye can see. Most fossil fuels will expire one day. Monoculture isn't a problem confined to biofuel production; it's an issue that had been studied for years in relation to large-scale food crop production. Synfuels still remain more expensive to produce than conventional fuels, mostly because more research, development and investment are necessary to make production economically viable. The organic material that makes biofuels is made of carbon dioxide absorbed by plants from the atmosphere as they grew. Biofuels refer to fuels made from plant materials. And alcohol fuels (including ethanol) can corrode or damage some of the metal and rubber fittings used in gasoline-powered engines. Examples include ancient people burning wood and branches to generate fire. Some of the disadvantages of biofuels apply mainly to low-diversity biofuel sourcescorn, soybeans, sugarcane, oil palmswhich are traditional agricultural crops. Central to the problem is corn's relatively high water requirement. Numerous unsaturated oils have undesirable burn properties. 2007. As a breeding ground for bacteria and other contaminants, landfills can allow pollution to contaminate the land, sea and air. Click to reveal The molecular bonds in oils low in saturated fats, which stay liquid at lower temperatures, vary from those high in saturated fats, which often form solids in average temperature ranges. 1. The cost of biofuel production can vary depending on the type of biofuel, the location, and the specific technologies used. Fossil fuels are non-renewable and release greenhouse gases during their combustion. One potential challenge to the reliability of biofuels is their limited availability, as they are only produced from certain feedstocks (as mentioned in the disadvantages section). Producers that focus on a single cash crop each year face an increased risk of pest development, water pollution, and catastrophic failure. Cellulosic ethanol is commonly made from sugarcane bagasse, a waste product from sugar processing, or from various grasses that can be cultivated on low-quality land. Biofuel is the fuel created through contemporary processes from biomass instead of the very gradual geological processes associated with the formation of fossil fuels, such as natural gas or oil. Jan. 31, 2007. 1 Feb. 2011. . After all, a better harvest would reduce prices and ensure there's enough corn or soybeans on hand to feed and fuel the world, right? Import Tuner. Let us know if you have suggestions to improve this article (requires login). Because of the higher gel point of many biodiesel producing oils than petroleum, it is difficult, if not impossible, to start a biodiesel engine in cold weather. Corn ethanol, for example, takes a great deal more energy to create than it creates itself when burned. As an alternative source of energy, they also reduce our reliance on fossil fuels, minimizing or emitting negative effects that come with the use of this polluting and limited source that has been powering our economies since the industrial revolution but has also brought about increased pollution levels and emissions of greenhouse gases. The development of a biofuels industry has great potential to stimulate economic development in rural areas with less job possibilities by creating new markets for crops and other agricultural products. These differences in state at a given temperature come from the oils' molecular makeup. Turning garbage into fuel is potentially an answer to two pressing problemsdiminishing the world's dependence on fossil fuels and an alternative to burying trash in landfills. Biofuels costs are affected by these fluctuations, so when the price of fossil fuels is high, biofuels can be more cost-competitive. This means that when garbage rots in landfills, that stinky gas can be used for energy! Concerns have arisen mainly due to the lack of cover left to protect the resulting fallow fields from erosion from wind and rain. First, there's the issue of yield. While every effort has been made to follow citation style rules, there may be some discrepancies. (Nov. 15, 2010)http://www.businessweek.com/magazine/content/07_06/b4020093.htm, Golden Fuel Systems. On the other hand, burning garbage produces air pollution and releases the chemicals and substances in the waste into the air. Perhaps the most straightforward of biofuel's drawbacks is the most obvious: It isn't petroleum-based fuel, so it will operate differently in engines designed for petroleum-based fuel. Many biofuel crops are applied to produce biodiesel. Air quality sensing of particulate matter shows that levels of this damaging pollutant are high around such sites.

Consumers living in a low-producing region need to have biofuel by moving through pipes or trucks to them. Unfortunately, that image is also a sign of monoculture, an agricultural problem that could conceivably get much worse due to biofuels. "Nature has not given us that selectivity to shift syngas to ethanol," notes chemical engineer Chornet, who started Enerkem in 2000 to make fuel from forestry residues, inspired by his father on Spain's island of Majorca, who made electricity by burning wood waste from his sawmill in the 1930s. In Brazil, ethanol biofuel is made primarily from sugarcane, and it is commonly used as a 100-percent-ethanol fuel or in gasoline blends containing 85 percent ethanol. Uses land that could be used to grow food. Industrial Pollution 6. Additionally, biofuel production can also lead to changes in land use patterns, which can displace local communities and increase the cost of land.
