What are biofuels?

Biofuels

are a type of renewable fuel, usually occurring in liquid form that have been distilled and made from different grains and animal fats. These elements, basic compounds for biofuels, are referred to as biomass, with the most popular corn. Other forms of biomass may include barley, sugar cane, soybeans, rapeseed and other traditional terraced crops. The two best known biofuels are ethanol and bionaft. Its base is a pure granular alcohol, which is identical in content with domestic liqueurs, such as monthly light or white flash produced in well hidden photographs during the US ban. Since 2009, ethanol has been used primarily as a federally authorized ingredient for gasoline. The purpose of the production of ethanol is to reduce pollution, greenhouse gas emissions and dependence on oil -based fuels, and countries that provide tem.

However, there are questions about the environmental wisdom of increased ethanol production. Although it is undoubtedly renewable fuel, it uses OBRovy amounts of grain that have previously been assigned to the production of animal feed or food for direct human consumption. This led to a significant global increase in the price of almost all commercially available foods, especially breads, cereals, pasta, pork, poultry and beef.

In addition, as federal mandates for the use of ethanol are expanding, other forested land is cleaned for agricultural purposes. Because the trees absorb carbon dioxide, their harvest could lead to an even greater greenhouse effect. Last but not least, increased biomass grains include increased use of herbicides, pesticides, fertilizers and agricultural equipment emissions.

bionaFta is similar to ethanol in that it is a renewable liquid, but is most often made of soybeans, rape or animal fat. Unlike unmilient ethanol that destroys rubber seals and seals in standard MOThe car torus is very close to the chemical composition on oil -based diesel. It can either be mixed with this fuel or is used as a direct substitute.

However, the

biodiesel production process represents the same problems as ethanol in terms of the redistribution of food sources and the conversion of forests and grasslands for agricultural use. While renewable fuels are certainly a wise idea, there are many debates about positives and negatives of biofuels. Although they are widely offered as better than oil -based fuels, they are far from clean. There is fear that biofuels, if it were made beyond the excess, could lead to acceleration of the problems themselves that were intended to cure.
