| MarketplaceSugar Cane BiofuelPosted on February 1, 2010. Biofuels and what they are You've heard the term biofuel but you do not know what that means. Biodiesel is a fuel that is derived from biomass has recently living organisms or their metabolic byproducts like cow manure. It is considered "green" because it comes from a renewable energy source, unlike other natural resources like oil, coal and nuclear fuels.
Agricultural products grown specifically for use as biofuels include corn and soybeans (primarily in the U.S.) as well as flaxseed and rapeseed (primarily in Europe).
Waste from industry, agriculture, forestry and households can also be used to produce bioenergy and straw, timber, manure, sewage, garbage and food scraps.
The production of biofuels to replace oil and natural gas is in active development, focusing on the use of cheap organic matter (usually cellulose, agricultural waste and sewage) in the efficient production of liquid biofuels and high efficiency gas net energy gain.
There are several current issues with biofuel production and use, which are currently under discussion in the popular media and scientific journals. These include: the "food cons fuel" debate, the levels of carbon emissions, the production of sustainable biofuels, deforestation and soil erosion, impact on water resources issues rights, poverty reduction potential, biofuel prices, energy balance and efficiency, and centralized and decentralized models of production.
What material can be used to produce biofuels? Conventional ethanol is made from sugarcane, maize, sorghum and sweet. Soybean oil and rapeseed oil are often used to make biodiesel, but coconut oil, palm oil, canola oil and jatropha nuts are also used worldwide.
The trees, grass, agricultural residues and municipal solid waste can also be converted into biofuels. Cellulose constitutes the majority of the structure of a plant and can be broken down into sugars that can then be fermented and made into ethanol. Recent research is that the process less costly and more efficient energy.
As the world's largest producer, Brazil uses sugar cane to make ethanol. Many other developing countries, such as those in southern Africa, produce large quantities of sugar and have the potential to become producers of ethanol. The Midwestern United States relies on corn for nearly a quarter of the world's ethanol, and China is rapidly becoming the leading provider of ethanol content.
Other countries with limited resources of fossil fuels are examining the prospect of production of domestic fuel supply. Thailand has an aggressive policy to make use of tapioca and sugar cane for ethanol production. In response to the recent adoption of the EU Biofuels Directive, member countries to increase their production of biodiesel. The Philippines has recently requested the inclusion of biodiesel from coconut oil into diesel fuel, oil, coconut was first used as fuel.
Cars, trucks and agricultural machines can run on all blends of biofuels with low volume, without any alteration. The guarantees relate to the current vehicles running on gas with ethanol up to ten percent. Fuel vehicles (FFV) runs on any combination of ethanol and gasoline. FFVs are sold in the United States, Brazil and China. As ethanol has a higher octane, it is used as a gasoline additive to improve the performance of the vehicle. In fact, many international racing teams use of ethanol because of its high performance qualities. Biodiesel blends of 20% showed similar operation in conventional diesel engines as diesel fuel.
Biofuels response to the current energy crisis? It may be too early to say but it was certainly an alternative source, in the meantime.
