BIODIESEL

  • Biodiesel is defined as the esters of higher fatty acids having similar physical properties to the diesel fuel and can be used as substitute.

    Unlike what has prevailed in everyday language, the term biodiesel is a very specific group of compounds methyl esters of higher fatty acids which are derived from organic oils and not any fuel organic origin which can be used in compression ignition engines (diesel engines ). The fact that the methyl esters derived from organic raw materials base, which is renewable, justify their characterization as biofuels .

    The ability of biodiesel to replace conventional diesel combustion engines are known for 2 decades. Biodiesel is proposed as an alternative to the plain vegetable oils of which the characteristics make them unsuitable for use in these engines. Over the last 10 years the production of biodiesel has made great development in the European Union, which is the largest producer in the world, and particularly in Germany. The increase in production is enhanced by the requirement of the EU Directive 2003/30/EC which provides for the introduction of biofuels in the markets of the Member States.

    The properties and characteristics of biodiesel, which is marketed in the European market, are specified by the European Standard EN14214.
