Updates? Let us know if you liked this article. Disadvantages of Biofuels 1. Web. But genetically modified crops have accidentally created unwanted and sometimes threatening traits like what happened during primary tests of a modified strain of corn. Most of the waste generated worldwide is biodegradable. The reliability of biofuels as an energy source depends on a variety of factors, such as the feedstocks used, the production methods employed, and the end-use of the biofuels. Traditional waste tire management strategies Advantages Disadvantages; Recycling and reclamation: Reduces global warming and helps preserve . Many biofuel crops are used to make biodiesel. 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 The pure form of ethanol (E100) can be used as a fuel for vehicles, but it is usually applied as an additive to gasoline to increase octane and enhance vehicle emissions. What are the disadvantages of biofuels? Feb. 5, 2007. Also, alcohol fuels (including ethanol) may corrode or damage some of the metal and rubber fittings utilized in gasoline-based engines. The character of biofuels when they are only produced from certain feedstocks, such as specific crops, like rapeseed, or certain waste materials, means that they may be in limited supply. It may cause food scarcity because of the lucrative prices of bioethanol some farmers may sacrifice food crops for Biofuel production 3. The water demands of some biofuel crops can put unsustainable pressure on local water resources if not handled carefully. "Growing Zone Information." 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. Greentumble was founded in the summer of 2015 by us, Sara and Ovi. Given the expense of converting this mix of dirt and heavy oils to more usable petroleum products, the province is not keen on alternative fuels. (Dec. 13, 2010)http://www.ers.usda.gov/Data/BiotechCrops/, Special Offer on Antivirus Software From HowStuffWorks and TotalAV Security. Horgan. 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. Its application in transport industry would cut a big part of the air pollution originating from this growing industry [2]. 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]. Partial combustion is a fuel-burning with insufficient oxygen to convert the biomass entirely to carbon dioxide and water. Bioenergy can reduce the waste problem. While technology may eventually narrow those ratios, the input-output energy ratio of modern biofuel production is a major drawback to its widespread use. The production cost per liter of ethanol is still high compared . 19 January 2011. Knowledge awaits. Biofuel is commonly advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels, particularly within the context of rising petroleum prices and increased concern over the contributions made by fossil fuels to global warming. Temperate zone plant biomass per hectare could be as high as 20 t. Switchgrass have reported yields up to 30 t ha 1. In addition, energy crops grown for biofuel can compete for the worlds natural habitats. The production of biofuels can be more expensive than the production of fossil fuels due to the costs of growing and processing the feedstocks. This fuel is made from the decomposition of organic matter. 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. The production and use of biofuels generates significantly less greenhouse gas emissions than the production and use of highly polluting fossil fuels. But in cases that seem as much science fiction as they are scientific fact, genetically modified crops have accidentally developed unintended -- and sometimes dangerous -- traits. Moreover, the crops that are grown to produce biomass absorb carbon dioxide which helps clean the air.

The problem is worse for pure vegetable oil as a fuel in so-called grease cars. Nitrogen added to drinking water can cause health problems, like methemoglobinemia, a disease that prevents infants from using the oxygen in their blood. Get a Britannica Premium subscription and gain access to exclusive content. Moisture is more likely to be absorbed by biofuels than fossil diesel, which causes problems in cold weather. Biofuel is used to power vehicles, and is being produced by gasification in countries such as Sweden, Austria, and the . The transition to biofuels will affect especially economic sectors of agriculture, manufacture, reprocessing, recycling, and transportation. It can be used in pure form (B100) or can be blended with petro-diesel in the form of B2 (2% biodiesel, 98% petroleum diesel), B5 (5% biodiesel, 95% . This can make them less practical for some applications, such as long-distance transportation. The sun stores resources into these materials thanks to photosynthesis. One alternative involves the use of highly diverse mixtures of species, with the North American tallgrass prairie as a specific example. . Biofuels are often produced from crops such as corn, sugarcane, and palm oil, which can be grown on a large scale. (Nov. 16, 2010)http://www.nytimes.com/2007/01/31/business/worldbusiness/31biofuel.html?adxnnl=1&adxnnlx=1290625375-G4EOxMpw99oBdvPcW6DvCw, Tsuneishi, Scott. 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. Meanwhile, E4Tech's study Sustainable Aviation FuelsFuelling the Future estimates a potential global supply of up to . Excessive use or improper application can leave surplus fertilizer in the soil, which is then washed through regional watersheds and transferred into rivers, lakes, and underground aquifers. They write new content and verify and edit content received from contributors. To learn more about biofuels, click to the next page. 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. And. It takes up to 1.4 gallons of ethanol to replicate the mileage that 1 gallon of gasoline can provide. The simple supply-and-demand economics of biofuels -- increase demand for corn, for example, and corn becomes more expensive -- can pose a threat to some regions' food security, or the access to affordable nutritious food for the region's population [source: Naylor]. Articles from Britannica Encyclopedias for elementary and high school students. This difference has an effect on the oils' viability as fuel. Unfortunately, that image is also a sign of monoculture, an agricultural problem that could conceivably get much worse due to biofuels. While both of these additives cause rapid and pleasing growth in many crops, they have drawbacks. 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. In general, biofuels can be a reliable energy source if they are produced and used in a responsible and sustainable manner. Some algal species contain up to 40 percent lipids by weight, which can be converted into biodiesel or synthetic petroleum. Most fossil fuels will expire one day. Fuel." 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. 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.. The production of biofuels can compete with food production for land and resources, which can lead to higher food prices. 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 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). 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. Industry researchers had found an answer in palm oil, a relatively easy-to-produce biofuel source. Biofuels are often not compatible with traditional fossil fuel infrastructure because they have different chemical and physical properties. Because biofuels can be produced from renewable resources, they bring less pollution to the planet. Biomass is plant or animal material like wood, energy crops, and waste from forests, farms, or yards utilized as fuel to generate electricity or heat. The amount of water used to grow biofuels varies depending on the type of biofuel, the location, and the farming practices used. See also carbon sequestration. Diverting that waste to anaerobic digestion would turn a cost into an opportunity, generating revenue from energy production and co-products. 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]. Required fields are marked *. 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. 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). and environmental chaos ensued. This lack of compatibility is one of the reasons that biofuels have not been widely adopted as a replacement for fossil fuels. When biofuels are burned, they produce significantly less carbon output and fewer toxins than carbon fuels. Another challenge is the limited energy density of biofuels. The biomass pretreatment is one of the keys to the best use of organic waste and thus enhance the production of a biogas plant. And once the chemicals are in the water supply, bad things can happen. (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. Lets explore the pros and cons of biofuels in order to better understand their future potential as our energy source. The proper way to grow biofuels to serve all needs simultaneously will continue to be a matter of much experimentation and debate, but the fast growth in biofuel production will likely continue. 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. Hydrogenating, or treating the oil with hydrogen, can mitigate this problem, but increased processing means increased cost [source: Journey to Forever].
