disadvantage of garbage biofuel

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. This lack of compatibility is one of the reasons that biofuels have not been widely adopted as a replacement for fossil fuels. 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. If you use ethanol for your vehicles, you reduce up to 86% of greenhouse gas emissions more than fossil fuel. However, this is not the only reason to encourage the use of biofuels. Some algal species contain up to 40 percent lipids by weight, which can be converted into biodiesel or synthetic petroleum. . They are cleaner fuels, meaning that they produce fewer emissions during burning. This means that more biofuel is required to produce the same amount of energy as a smaller amount of fossil fuel. 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]. (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. 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. Biofuels require agricultural land which is already limited. However, fuel ethanol contains denaturants to make fuel ethanol undrinkable. In any case, the regeneration of biofuels is also not fast enough to be considered a renewable energy source. They are perennial. June 12-13, 2003. 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. In addition, biofuels are biodegradable, which reduces the risk of contamination of and underground water during transportation, storage, or use. While every effort has been made to follow citation style rules, there may be some discrepancies. Biomass energy comes from organic materials, such as plants, so that is why it receives classification as a renewable source of energy.

This way biofuels also decrease our dependence on foreign oil, which helps to reduce our trade deficit and improve energy security on a country level. Even if plant waste can be used as raw material, the demand for these products will still exist. Some crops will grow better in certain areas and may not grow at all in other regions. The ragged stripes stretching from east to west are growing zones: regions where water supply, temperature and sunlight make hospitable climates for certain types of plants. 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. Updates? #1 Land use changes and land grabbing "Once a Dream Fuel, Palm Oil May Be an Eco-Nightmare." Biogas reduces Soil and water pollution. It contributes to deforestation 4. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas. 23 Biomass Energy Advantages and Disadvantages - Vittana.org Required fields are marked *. However, most of the time, the word biomass simply signifies the biological raw material from which the fuel is made, or some kind of thermally-chemically changed solid end product, like torrefied pellets or briquettes.
