For every 1 tonne of biodiesel that is manufactured, 100 kg of glycerol are produced. Originally, there was a valuable market for the glycerol, which assisted the economics of the process as a whole. However, with the increase in global biodiesel production, the market price for this crude glycerol (containing 20% water and catalyst residues ...
Biodiesel is a liquid fuel composed of vegetable oils and or animal fats. To create the gasoline itself, these subsequent liquids are combined with alcohol. Biodiesel is used to fuel compression ignition engines, otherwise known as diesel engines. The most common product of biodiesel is B20, a 20:80 blend: 20% biodiesel to 80% petroleum diesel.
Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass , which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [ 1 ]
For the purposes of the definition alternative fuel in subsection 2(1) of the Act, the following, when used as the sole source of direct propulsion energy of a motor vehicle, are prescribed to be alternative fuels: (a) ethanol; (b) methanol; (c) propane gas; (d) natural gas; (e) hydrogen; (f) electricity;
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
The availability of biodiesel around the World is increasing. It is estimated that by 2010 the market for biodiesel will be 7.5 billion litres (2 billion USgallons) in the U.S and 9.5 billion litres (2.5 billion USgallons) in Europe. [16] Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17]

Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. In 2010 worldwide biofuel production reached 105 billion liters (28 billion gallons US), up 17% from 2009, and biofuels provided 2.7% of the world's fuels for road transport, a contribution largely made up of ethanol and biodiesel.
