Biofuel is any fuel that is derived from biomass - recently living organisms or their metabolic byproducts, such as manure from cows. It is a renewable energy source, unlike other natural resources such as petroleum, coal, and nuclear fuels.
Ethanol is manufactured from microbial conversion of biomass materials through fermentation. Ethanol contains 35% oxygen. The production process consists of conversion of biomass to fermentable sugars, fermentation of sugars to ethanol, and the separation and purification of the ethanol. Fermentation initially produces ethanol containing a substantial amount of water.
Distillation removes the majority of water to yield about 95% purity ethanol, the balance being water. This mixture is called hydrous ethanol. If the remaining water is removed in a further process, the ethanol is called anhydrous ethanol and is suitable for blending into gasoline. Ethanol is "denatured" prior to leaving the plant to make it unfit for human consumption by addition of a small amount of products such as gasoline.
Biodiesel fuels are oxygenated organic compounds - methyl or ethyl esters - derived from a variety of renewable sources such as vegetable oil, animal fat, and cooking oil. The oxygen contained in biodiesel makes it unstable and requires stabilization to avoid storage problems. Rapeseed methyl ester (RME) diesel, derived from rapeseed oil, is the most common biodiesel fuel available in Europe. In the United States, biodiesel from soybean oil, called soy methyl ester diesel, is the most common biodiesel. Collectively, these fuels are referred to as fatty acid methyl esters (FAME).
Russia majorly produces bioethanol. Russia's government has been putting more emphasis on fuel ethanol development, as Russia is lacking in suitable sources for biodiesel production.
The report Russia Biofuels Market Potential provides comprehensive coverage of Russia's ethanol and biodiesel market.
