Ethanol-makerand oil refinerValero Energy Corp. has also invested in Enerkem. As a breeding ground for bacteria and other contaminants, landfills can allow pollution to contaminate the land, sea and air. Air quality sensing of particulate matter shows that levels of this damaging pollutant are high around such sites. Although this is an economically attractive measure, the greater economic profitability for the farmer can make serious environmental disadvantages. It took millions of years for organic materials to transform into fossil fuels stores we currently mine for our energy needs. But factor in a number of other complicating aspects, and biofuel often carries a heavy price. Advantages and disadvantages of renewable energy. 1. An important consideration is the gel point; a fuel that becomes solid above the freezing point of water is not very useful in a cold location. There are a few potential negative effects of biofuels on the environment and economy that need to be considered when forming an opinion about their use in the future. "You can place it in refineries throughout North America. What are the disadvantages of biofuels? . Ethanol also absorbs water easily giving it a high tendency to corrode materials. True, a plant-based fuel comes from a renewable source, while fossil fuels will eventually run out. According to some estimates, expansion by Indonesian palm oil plantations caused the vast majority of that nation's deforestation in the late '80s and '90s. These landfills not only spread foul smell but also contaminate underground water sources. The energy that is obtained from biofuels is known as bioenergy. Moreover, not every climate zone is proper for a high-yield crop that could produce biodiesel economically. These differences in state at a given temperature come from the oils' molecular makeup. "Biofuels and their Impact on Food Prices." 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. If more people turn to biofuels, a country can diminish its dependence on fossil fuels. An unfortunate disadvantage of biogas today is that the systems used in the production of biogas are not efficient. For example, the density of corn-based ethanol is higher than gasoline; fuel injectors must be larger in an ethanol-only engine to suit the fuel flow of a comparable gasoline engine. Nevertheless, in 2012 Edmonton will host a chemical plant owned by Enerkem that will turn garbage into 36 million liters of ethanol and methanol per year. Knowledge awaits. These air pollutants can cause respiratory and cardiovascular problems, as well as damage to crops, forests, and other ecosystems. And once the chemicals are in the water supply, bad things can happen. And the singular nature of a monoculture crop increases the risk of a total loss for the farmer; imagine the damage if a severe strain of corn blight hit an ethanol-producing corn farm [source: Altieri]. The sun stores resources into these materials thanks to photosynthesis. 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. Uses land that could be used to grow food. (Dec. 11, 2010)http://www.extension.umn.edu/distribution/horticulture/dg2923.html, Rosenthal, Elisabeth. In general, biofuels can be a reliable energy source if they are produced and used in a responsible and sustainable manner. That has yet to be an energy source that comes without some drawback. Likewise, the nutrients that are put back into the soil through crop rotation and allowing fields to lay fallow disappear under intense monocultural farming. Biofuel is used to power vehicles, and is being produced by gasification in countries such as Sweden, Austria, and the . Biofuel and fertiliser can be made from putrefying gasses emitted by rotting food, in specialist containers called anaeorbic digestors. Pure ethanol is difficult to vaporize meaning starting a car in cold weather could be more difficult that a car that runs on petrol. "Preventing Pollution Problems from Lawn and Garden Fertilizers." The second most common liquid biofuel is biodiesel, which is made primarily from oily plants (such as the soybean or oil palm) and to a lesser extent from other oily sources (such as waste cooking fat from restaurant deep-frying). This website is using a security service to protect itself from online attacks. 1 Feb. 2011. An example of such practice could be plantation of diverse prairie grass mixtures. The clearing of land can also result in the sudden release of a large amount of carbon dioxide as the plant matter that it contains is burned or allowed to decay. However, fuel ethanol contains denaturants to make fuel ethanol undrinkable. Required fields are marked *. In a possible moderate ethanol production scenario that includes trash collection and cellulosic ethanol production, sugarcane has the potential to provide sufficient ethanol to meet 14% of Australia's . But the conversions add time and money to the biofuel equation, something that can be off-putting for potential biofuel users. Less carbon emissions . Future Price Growth 8. sunlight and water. . Pure ethanol and biodiesel are nontoxic and biodegradable, and if spilled, they break down into harmless substances. Most fossil fuels will expire one day. Feb. 5, 2007. Plantation owners prepared their operations to meet the demand . The fourth generation of biofuels includes electro fuels and solar fuels. One of the key challenges in making the use of biofuels more sustainable over the long term is ensuring that they are sourced from feedstocks that have a low carbon footprint and are not in competition with food production. Furthermore, the burning of coal and oil raises the temperature and warms the planet. (Dec. 13, 2010)http://www.ucsusa.org/food_and_agriculture/science_and_impacts/impacts_genetic_engineering/environmental-effects-of.html, Naylor, Rosamond L. et al. 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. For example, Range Fuels in Georgia similarly attempted to gasify waste from the pulp and paper industry and transform it into ethanol directly but foundered in perfecting its catalysts. The garbage to biofuel process is not only an alternative way to produce home . However, ready access to food imports, and the ease of exporting, hinge on a wide range of political and social factors. Land use is also a major factor in evaluating the benefits of biofuels. Researchers found that the crop engineered to fight off a moth known as prey on corn created pollen that could kill larvae of the monarch butterfly. Add other resource costs into the equation, such as the gallons of fresh water needed to grow the plants and the amount of fertilizer needed to keep them healthy, and it becomes even harder to equate biofuel with real energy and carbon emission savings. Drivers of vehicles who use these fuels usually have to install heating units to protect the fuel tank and lines free from gelled fuel or dual-fuel mechanisms flushing the engine with petroleum diesel during start-up and shut-down. Farmers of corn, cotton, and soybeans, all possible sources of biofuel, are increasingly planting genetically modified types of those plants. Unfortunately, that image is also a sign of monoculture, an agricultural problem that could conceivably get much worse due to biofuels. The burning of fossil fuels generates a variety of air pollutants, including carbon monoxide, nitrogen oxides, and particulate matter. Water Usage 7. Read more about us. Although the creation of biofuels produces carbon dioxide as a byproduct, it is often used to grow the plants that are converted into fuel. Gasoline is refined from crude oil, a non-renewable resource. Can Renewable Energies Solve the Grave Problem of Climate Change? Phosphorus has been implicated as a trigger of localized algae blooms: The tiny aquatic plants feed off it and rapidly reproduce, often killing other plants and aquatic animals by reducing the amount of oxygen in water or by releasing toxic chemicals. This difference affects the viability of the oil as fuel. All rights reserved. ), which scientists call biomass. "The Ripple Effect: Biofuels, Food Security and the Environment." In general, biofuels are more expensive to produce than fossil fuels on a per-unit energy basis. Biofuels can be extracted from the waste of those crops as well. "Biofuel" is a major buzzword in transportation circles these days, and for good reason. Exorbitant Production Costs 2. We are a couple of environmentalists who seek inspiration for life in simple values based on our love for nature. But those fertilizers can have harmful effects on the surrounding environment, and expanded biofuel production could mean a major pollution threat to sources of fresh water. It may produce 100 gallons of the fuel out of one season's crop. Examples include ancient people burning wood and branches to generate fire. About 3.5 million tons of garbage is discarded in landfills every day. The production of biofuels can be more expensive than the production of fossil fuels due to the costs of growing and processing the feedstocks. Biofuels are obtained from crops and plants that contain large amounts of sugar. While the first is a bit beyond the control of biofuel producers, the second is at the core of a potentially serious drawback of plant-based fuels: The water demands of some biofuel-producing crops could put unsustainable pressure on local water resources if not managed wisely. See Terms of Use and Privacy Policy, Find out More about Renewable Energy Device & Equipment in Linquip, See List of all Renewable Energy Manufacturing Companies in Linquip. 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. Monoculture refers to the practice of growing one heavily concentrated crop, rather than the rotation of various crops through a farmer's fields over time. Making biofuels from waste makes dollars--and sense, Edmonton is Canada's chief oil city as well as the capital of Alberta, the province that hosts the bulk of the country's tar sands. Biofuel Disadvantage : Environmental Impact. For example, if crops grown for biofuels are planted on land that could be used for growing food crops. However, ease of access to food imports and the export depends on a wide variety of political and social factors. Quick Navigation for Advantages and disadvantages of biofuels, [1] https://www.ncbi.nlm.nih.gov/books/NBK196452/. (Dec. 11, 2010)http://www.burpee.com/gardening/content/gygg/growing-zone-information/growingzoneinfo.html, Carey, John et al. Consequently, it makes sense to look for an unsaturated oil as a biofuel source. However, in terms of cost, the overall benefits of using biofuels are much higher. "Adoption of Genetically Engineered Crops in the U.S." July 1, 2010. A prime example of this occurred in the early 2000s. Biofuels are often produced from crops such as corn, sugarcane, and palm oil, which can be grown on a large scale. What is biomass? These materials include plant matter such as corn, soybeans, and sugarcane, as well as animal fats and agricultural waste. The quantity of vegetable oil available in an acre of crops can range greatly, from 18 gallons for corn to 635 gallons per acre for oil palm. You may think that biofuels are used mainly in transport, but thats not all. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Linquipis a Professional Network for Equipment manufacturers, industrial customers, and service providers, Copyright 2022 Linquip Company. Disadvantages of Waste Management: We have now seen the merits of waste management in detail. 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. 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. Biogas is used predominantly in the electricity sector. Unlike the first-generation ethanol biofuel produced from food crops, second-generation cellulosic ethanol is derived from low-value biomass that possesses a high cellulose content, including wood chips, crop residues, and municipal waste. On the other hand, because many biofuel feedstocks require land, water, and other resources, research suggests that biofuel production may give rise to several undesirable effects. The benefits of biofuels compared to fossil fuels depend on a variety of factors that need to be considered when used on a large scale. They write new content and verify and edit content received from contributors. Disadvantages of Biomass Energy This is an ethanol refinery. Therefore, the use of biofuels is less of a drain on the wallet. This lack of compatibility is one of the reasons that biofuels have not been widely adopted as a replacement for fossil fuels. : Premium Gasoline Delivers Premium Benefits to Your Car. Create your free account or Sign in to continue. The heat, in turn, can be used to run generators in a power plant to produce electricity. Hundreds and even thousands of hectares of unbroken acres of one crop are an irresistible destination for plant pests; pest groups can explode uncontrollably in this tempting environment. China's Xi Outshines Trump as the World's Future Energy Leader, Fact or Fiction? And while the range of oil-producing crops considered viable for biofuel production is wide enough to fit most growing zones, the most productive crops simply won't grow everywhere. This may sound contradictory to the advantages of biofuels mentioned earlier in this article. As of now, the cost of biofuels in the market is the same as gasoline. It seemed like a win-win idea: European demand for biofuel was set to spike, driven in part by regulations aimed at reducing greenhouse gas emissions. In small countries, or in municipalities where landfills are full and . Biofuels are definitely cheaper than fossil fuels. Liquid biofuels are of particular interest because of the vast infrastructure already in place to use them, especially for transportation. As crude oil prices rise, we need several other alternative energy solutions to reduce dependence on fossil fuels. Drivers of vehicles using these fuels often have heating units installed to keep the fuel tank and lines free from gelled fuel, or install dual-fuel systems that flush the engine with petroleum diesel on start-up and shut-down. A pig farmer, for example, may have to pay a few extra dollars per bushel to buy corn to feed his livestock. The production of biofuels can in some cases compete with food production in several ways. Consumers living in a low-producing region would need to have biofuel trucked or piped to them, increasing both cost and the amount of emissions produced in production and transport [source: Pimentel]. Sugar Cane Until recently, sugar cane was the world's main source of ethanol, because of its prevalence in Brazil. According to the report of RFA (Renewable Fuels Association) in February 2019, ethanol is the highest-octane and the least expensive motor fuel on earth. Cellulosic biomas obtained from non-food sources, including trees and grasses, is also being developed as a raw material for ethanol production. Also, It increases microbial growth in the engine, making the engine filters clogged. Bioethanol is a type of alcohol produced by fermentation, often from carbohydrates made in sugar or starchy crops like corn, sugarcane, or sweet sorghum. The problem is even worse for pure vegetable oil, used as fuel in so-called "greasecars." In this respect, ethanol made from corn represents a relatively small energy gain; the energy gain from sugarcane is greater and that from cellulosic ethanol or algae biodiesel could be even greater. Hundreds -- even thousands -- of unbroken acres of one crop offer an irresistible target for plant pests; pest populations can explode beyond control in such a tempting environment. (Dec. 13, 2010)http://www.goldenfuelsystems.com/index.php, Journey to Forever. 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. But while different crops can be converted to biodiesel through the same process, the resulting fuel can be very different in its ability to produce energy. Biodiesel produces less toxic pollutants and greenhouse gases than petroleum diesel. The amount of vegetable oil available in an acre of crops can vary widely, from 18 gallons per acre for corn to 635 gallons for oil palm [source: Journey to Forever]. Biofuel production is currently equivalent to just a tiny fraction. Similarly, BlueFire Ethanol turns waste into ethanol by using sulfuric acid to release the cellulose in the trash and then adds enzymes and microbes to ferment it into fuel. Please copy/paste the following text to properly cite this HowStuffWorks.com article: Matt Cunningham Advantages and Disadvantages of Biomass Energy Biomass Energy . Enerkem takes the "fluff" of municipal solid wastethe plastics, textiles and wood that isn't recycled or the leftovers of agriculture or forestrygasifies it and, using catalysts and water, transforms the gas via multiple chemical steps into ethanol or other products. In diverting arable land and feedstock from the human food chain, biofuel production can affect the economics of food price and availability. Industrial Pollution 6. Performance & security by Cloudflare. Because of the higher-than-petroleum gel point of many biodiesel-producing oils, a biodiesel engine can be difficult -- if not impossible -- to start in cold weather. On the other hand, burning garbage produces air pollution and releases the chemicals and substances in the waste into the air. It increases costs as well as the emissions produced in production and transport. After the incineration process is complete, the total mass of the remaining garbage can be reduced by up to 85 percent, while its volume may shrink by as much as 95 percent [5].. (Jan. 14, 2011)http://www.springerlink.com/content/r1552355771656v0/, Rosen, C.J. 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. 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]. The process creates a synthetic gas (syngas), which can then be used for a wide variety of applications. Additionally, the amount of water used in biofuel production is also affected by the specific farming practices used. Technical Challenges 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. If the land used to grow a biofuel feedstock has to be cleared of native vegetation, then ecological damage is done in three ways. 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. The production and use of biofuels generates significantly less greenhouse gas emissions than the production and use of highly polluting fossil fuels. It occupies agricultural space from other crops, which can cause many problems. It isn't as effective a fuel as traditional gasoline. Fueling homes, businesses, and vehicles with biofuels are less expensive compared to fossil fuels. The liquid biofuel in greatest production is ethanol (ethyl alcohol), which is made by fermenting starch or sugar. Compatibility refers to the ability of a fuel to be used in existing infrastructure and equipment without modification or damage. Biofuel production boosts the demand for suitable biofuel products and strengthens the agriculture industry. Biofuels may emit lower carbon footprints but the process involved in the production of these fuels largely depends on oil and water. Biofuels are renewable. (Nov. 16, 2010)http://www.nytimes.com/2007/01/31/business/worldbusiness/31biofuel.html?adxnnl=1&adxnnlx=1290625375-G4EOxMpw99oBdvPcW6DvCw, Tsuneishi, Scott. Producers that focus on a single cash crop each year face an increased risk of pest development, water pollution, and catastrophic failure. However, other biofuel crops, such as switchgrass and miscanthus, are considered to be low-input crops and need less pesticides. Captured carbon dioxide could be sequestered (stored) in long-term repositories such as geologic formations beneath the land, in sediments of the deep ocean, or conceivably as solids such as carbonates. Cloudflare Ray ID: 7a2e12d729352bd1 This may involve the use of advanced technologies. Diverting that waste to anaerobic digestion would turn a cost into an opportunity, generating revenue from energy production and co-products. With international trends swinging toward sustainable transportation, fuels such as corn-based ethanol and biodiesel from soy, switchgrass and palm oil seem like a good step toward cleaner, greener highways. 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. Biodiesel can be made from vegetable oils and animal fats. While technology eventually will limit these ratios, the ratio of energy input to the output of modern biofuel production is an important disadvantage to its widespread use. Its lubricating properties are significantly better. There are four generations of biofuels based on how they are made. After all, a better harvest will lower prices and ensure there is enough corn or soybeans on hand to feed and provide the fuel to the world. Our goal is to inspire people to change their attitudes and behaviors toward a more sustainable life. Its use also leads to a significant reduction of particulate matter emissions, the term used to explain solid particles and liquid droplets in the air. This means large scale production to supply for a large population is still not possible. 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. The development of new biofuels technologies can support innovation and drive economic growth in a sustainable way. And while biofuel is not as clean as other renewables and won't get us out of the woods when it comes to reversing the impacts of climate change, it is a reliable renewable source. It has the same advantages as for AD (items 3 to 6 inclusive) over spreading untreated organic waste material on land. Anything that is local comes with an extra benefit. . Carbon monoxide emissions are lower than that . "Bioethanol." : Advantages & Disadvantages of. But that price quickly trickles down to consumers. But large-scale biofuel production -- especially using corn, and in arid parts of the world -- will have to share finite water resources with drinking and irrigation needs. The development of a biofuels industry can have both positive and negative economic impacts, depending on the specific circumstances. Plant-based fuel can be produced almost anywhere, comes from a renewable resource and often produces cleaner emissions than petroleum-based fuel. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. 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. (Jan. 14, 2011)http://www.afpc.tamu.edu/pubs/2/446/RR%2006-2.pdf, McKenna, Phil. One way to deal with this lies in simple diplomacy: The globalization of world commerce means that today it is easier than ever to transfer food supplies from one point of the world to another in response to increased need. Biodiesel, which has found greatest acceptance in Europe, is used in diesel engines and usually blended with petroleum diesel fuel in various percentages. However, this is not the only reason to encourage the use of biofuels. The generation of biofuels, a priori, represents several advantages over obtaining fossil fuels used to get fossil energy.The main advantage is that the regeneration of resources does not take millions of years as it happens with coal, oil, or natural gas.. . Scientists sounded the alarm, and further tests by academic and industry researchers confirmed that the corn's pollen posed a threat to monarchs. There is also no need to convert the engine. "Food vs. The burning of biofuels generates fewer air pollutants than the burning of fossil fuels, which can improve air quality and public health. However, the high greenhouse emissions, deadly air pollution, instable fossil-based energy prices, and strong growth of global transportation fuel demand have boosted extensive research efforts in developing bioenergy. Jan. 31, 2007. The use of biofuels can help to reduce our reliance on fossil fuels and contribute to a more sustainable energy system. Traditional waste tire management strategies Advantages Disadvantages; Recycling and reclamation: Reduces global warming and helps preserve . Ethanol-production facilities use far more electricity to run than they produce in fuel. Thanks for reading Scientific American. This is due to the fact that biofuels are derived from renewable resources, such as crops and waste materials, which is more expensive to grow and process than fossil fuels. All Rights Reserved. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. They emit less carbon dioxide and other emissions when burned than standard diesel. In theory, this sounds like a terrific way to keep up with biofuel crop demand. If farmers are incentivized to plant crops that are not well suited for the location, they may end up needing more water than any other crops would. Biofuel Biomass is the only renewable energy source that can be converted into liquid biofuels such as ethanol and biodiesel. In the United States the Energy Independence and Security Act of 2007 mandated the use of 136 billion litres (36 billion gallons) of biofuels annually by 2022, more than a sixfold increase over 2006 production levels. Biofuels are a more. But since many popular biofuel crops, such as corn and soybeans, are also popular food sources for much of the world, it stands to reason that the problems related to monoculture could get much worse as consumers demand more biofuel. They are found in liquid, solid or gas states. Aug. 11, 2006. While both of these additives cause rapid and pleasing growth in many crops, they have drawbacks. Feeding aquatic organisms from such contaminated water can lead to their death, as the oxygen in these waters is reduced and toxins are introduced into it.
