Such biofuels could be burned directly to generate electricity or converted to liquid fuels as technologies develop. The Pros and Cons of Ethanol Fuel - Treehugger Click to reveal Advantages of Biofuels Biofuels costs have been declining and are likely to be far cheaper than petrol and other fossil fuels. 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. 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. In the United States ethanol biofuel is made primarily from corn (maize) grain, and it is typically blended with gasoline to produce gasohol, a fuel that is 10 percent ethanol. 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. Source: New York Times, June 2, 2017. Biofuels are made from various sources, including manure, crop waste, algae, other byproducts, and plants grown specifically for fuel. 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. 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. Not Rotating the Crop 3. List of Disadvantages of Algae Biofuel. Jan. 31, 2007. Lets explore the pros and cons of biofuels in order to better understand their future potential as our energy source. Our goal is to inspire people to change their attitudes and behaviors toward a more sustainable life. In general, biofuels are more expensive to produce than fossil fuels on a per-unit energy basis. When the plant biomass is burned, it releases this absorbed carbon dioxide back into the atmosphere. 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. Biofuel Disadvantages: In the creation of first generation biofuels, huge amounts of land are needed. The use of waste biomass to generate energy can decrease waste management problems, pollution, greenhouse gaseous emissions and the use of fossil fuels. At the moment, biofuels are not compatible with all types of vehicles and equipment. Therefore, the use of biofuels is less of a drain on the wallet. What are the economic drawbacks of using biofuels. 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. About 3.5 million tons of garbage is discarded in landfills every day. Biofuel production boosts the demand for suitable biofuel products and strengthens the agriculture industry. 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. The major disadvantage to using algae to produce biofuels is the cost, which in part is due to the fact that the practice of using algae to produce biofuels is relatively new and requires additional research and development to find less costly production methods. Advantages and Disadvantages of Waste Management - Wisestep In diverting arable land and feedstock from the human food chain, biofuel production can affect the economics of food price and availability. The garbage to biofuel process is not only an alternative way to produce home . As a result, looking for unsaturated oil as a biofuel source is reasonable. This makes it something close to a self-sustaining system. It occupies agricultural space from other crops, which can cause many problems. Liquid biofuels are of particular interest because of the vast infrastructure already in place to use them, especially for transportation. Please refer to the appropriate style manual or other sources if you have any questions. Other biofuels include methane gas and biogaswhich can be derived from the decomposition of biomass in the absence of oxygenand methanol, butanol, and dimethyl etherwhich are in development. However, other biofuel crops, such as switchgrass and miscanthus, are considered to be low-input crops and need less pesticides. When done right and well-regulated, the production of biofuels has potential to actually support local biodiversity by promoting the growth of crops that are providing support to soils and leave soils less prone to erosion. To meet the increasing demand for biofuels, farmers may convert natural habitats, such as forests and grasslands, into croplands. Researchers are investigating ways to genetically engineer less thirsty crops, and carefully planning what biofuel crops to plant in a given region can mitigate this problem [source: Lau]. This one relates to the little multicolored maps on the backs of seed packets. Growing demand for food-biofuel crops may have a positive result for crop producers due to higher prices for their products. The mere biomass energy definition of turning waste to electricity is an exciting prospect and one that any logic dictates as a good idea to pursue. 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. . And alcohol fuels (including ethanol) can corrode or damage some of the metal and rubber fittings used in gasoline-powered engines. Researchers are working to increase biofuel yields from weather-tolerant crops [source: Lau]. Biofuels, and the process of integrating them into our fuel use habits, can be costly. It isn't as effective a fuel as traditional gasoline. IATA believes that by 2020 we could see 3%-4% of fuel comprised of second generation biofuels, which is made from biomass, agricultural residues or waste, rather than from the oil crops used for first generation biofuels. The burning of biofuels generates fewer air pollutants than the burning of fossil fuels, which can improve air quality and public health. But large-scale biofuel production, especially corn products and in arid regions of the world, has to share limited water resources with drinking and irrigation needs. Corrections? The use of algae and cyanobacteria as a source of third-generation biodiesel holds promise but has been difficult to develop economically. 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. Relying on produce from halfway around the globe to feed a hungry nation is a risky price to pay for widespread biofuel integration into the world's energy supplies. Its worth noting that the negative effects of biofuels can be mitigated by adopting appropriate policies and regulations, such as implementing sustainable land use practices, supporting research and development of advanced biofuels, and promoting the use of biofuels in a way that doesnt compete with food production. You can substitute it for corn ethanol if produced at a lower cost. These factors are mainly taken into account under the section of disadvantages and will help you understand the complexity of the situation when it comes to finding new energy sources that would replace fossil fuels entirely. Some estimates state that algae and cyanobacteria could yield between 10 and 100 times more fuel per unit area than second-generation biofuels. The heat, in turn, can be used to run generators in a power plant to produce electricity. 6. 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. Disadvantages of Biofuels Production of biofuels can be quite inefficient Large amounts of raw materials have to be used Significant greenhouse gas emissions in the production chain Use of chemical fertilizers and pesticides High initial investments required Increase in global food prices Global hunger and starvation High water demand 1. Loss of natural habitat can change the hydrology, increase erosion, and generally reduce biodiversity of wildlife areas. Most of the waste generated worldwide is biodegradable. Fuel." The second generation biofuels are produced from lignocellulosic, woody biomass, or agricultural waste. In the end, making a fuel from garbage remains a promising opportunityas long as the waste is already divvied up into its own component parts, as is happening in Edmonton and at the Three Rivers landfill near Pontotoc, Miss. Bioenergy can reduce the waste problem. Just consider: biodiesel is a biodegradable fuel that releases less emissions when burned. 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. Discover world-changing science. Biofuel is used to power vehicles, and is being produced by gasification in countries such as Sweden, Austria, and the . Changes in farming in developing countries - BBC Bitesize Exorbitant Production Costs 2. Hydrogenating, or treating the oil with hydrogen, can mitigate this problem, but increased processing means increased cost [source: Journey to Forever]. Whereas oil is a finite resource and comes from unique materials, biofuels can be produced from a broad variety of ingredients, including crop waste, manure, and other by-products. For the billions of people living on only a few dollars per day, even a slight increase in food prices could jeopardize their access to proper nutrition. These materials include plant matter such as corn, soybeans, and sugarcane, as well as animal fats and agricultural waste. Knowledge awaits. There are some complicating aspects about disadvantages of biofuels that we should look at. Biodiesel can be made from vegetable oils and animal fats. When biodiesel is utilized as a combustible fuel, the engine durability increases. Biofuels Pros And Cons - Science Trends As of now, the interest and capital investment being put into biofuel production is fairly low, but it can match demand. But is this energy source such a positive news as it seems at the first glance? Biofuels can be extracted from the waste of those crops as well. The production of biofuels can in some cases compete with food production in several ways. This difference affects the viability of the oil as fuel. One alternative involves the use of highly diverse mixtures of species, with the North American tallgrass prairie as a specific example. Given all the negative effects, ethanol which is derived from crops does not make economical sense as a mainstream biofuel. "10 Disadvantages of Biofuels" Biofuels are obtained from crops and plants that contain large amounts of sugar. A number of manufacturers sell biodiesel and grease car conversion components, and some others find methods to overcome the gelling problem. The production of biofuels often leads to land use changes, such as the conversion of natural habitats to cropland. 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].. Biofuels are derived from the decomposition of biological or organic waste. However, some biofuel crops, such as corn and sugarcane, are considered to be water-intensive and their production requires large amounts of irrigation. Except providing new livelihood opportunities for local families, they could also represent a sustainable and innovative option that will contribute to rural development. Biofuels Disadvantages There are some complicating aspects about disadvantages of biofuels that we should look at. By using biofuels as an alternative energy source, we can reduce our reliance on fossil fuels, which can help to reduce our impact on the environment and contribute to a more sustainable energy system that is more locally based. University of Minnesota. Synfuels still remain more expensive to produce than conventional fuels, mostly because more research, development and investment are necessary to make production economically viable. Despite the development of various technologies for converting waste tires into biofuels, there is a need for more cost-effective and efficient methods that can be scaled up for commercial production. Under this vision, biofuel crops would remove carbon dioxide from the air as they grow, and energy facilities would capture the carbon dioxide given off as biofuels are burned to generate power. Ethanol can be used instead of gasoline in many cars. "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. Bioethanol: Production, Advantages, Disadvantages And Environmental Impacts . Create your free account or Sign in to continue. What is biofuel? What are the advantages and disadvantages? Biofuels could be a sustainable energy source over the long term if they are produced and used in a responsible and well-planned manner when all the pros and cons of biofuels versus fossil fuels are considered. One alternative involves the use of highly diverse mixtures of species, with the North American tallgrass prairie as a specific example. One of the main advantages of biofuels is their relatively low cost. With the growth of the biofuel industry, more jobs will be created, which will help keep the economy secure. Advantages and Disadvantages of Anaerobic Digestion vs Composting While every effort has been made to follow citation style rules, there may be some discrepancies. It might seem counterintuitive at first, but some scientists argue that widespread biofuel production is a negative-sum game: Producing enough biodiesel or ethanol to replace one gallon of petroleum fuel, they argue, requires the energy equivalent to several gallons' worth of petroleum fuel [source: Pimentel]. . It contributes to deforestation 4. For example, bioethanol and biodiesel have a higher tendency to absorb moisture than fossil fuels, which can cause corrosion in fuel systems and engines. For the billions of people who live on only a few dollars per day, even a small increase in food prices could put their access to proper nutrition at risk. 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. Even solar energy, the long-touted saviour of the ever expanding human appetite for energy is decades away from being feasible on a large scale and without the impact that comes from manipulating toxic chemicals into PV panels. The greenhouse emission potential of biofuel varies considerably, from levels comparable to fossil fuels in some situations to negative emissions in others. Farmers of corn, cotton, and soybeans, all possible sources of biofuel, are increasingly planting genetically modified types of those plants. Corn ethanol, for example, takes a great deal more energy to create than it creates itself when burned. 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. Let's start with one of the main arguments against the use of biofuels. For example, the production of biofuels can create jobs and stimulate economic development, but it can also lead to higher food prices and competition with other industries for resources.
