Biodiesel is an eco-friendly alternative fuel. It is typically produced by reacting vegetable oils catalytically with a short-chain aliphatic alcohol through transesterification and esterification.

Biodiesel can be used in its pure form (B100), or blended with petroleum diesel. The ‘B’ factor referred to in the description is an internationally recognised system for indicating the amount of biodiesel in a blend or mixture. The number after the "B" denotes the percentage of biodiesel in the blend, e.g. B5 is a mixture of 5 % biodiesel and 95% other product, usually petroleum diesel.

Biodiesel has many environmentally beneficial properties. It is non-toxic, biodegradable, and can be produced using renewable and sustainable raw materials. Biodiesel contains virtually no sulfur, lead or aromatics. The use and production of biodiesel can reduce unburned hydrocarbons, carbon monoxide, carbon dioxide emissions and particulate matter, compared to petroleum diesel. In United States, biodiesel is registered as a fuel and fuel additive with the Environmental Protection Agency (EPA) and meets clean diesel standards established by the California Air Resources Board (CARB).

Application :
  • Used as an industrial solvent for metal cleaning, such as dirty or greasy engine or other machine parts.
  • Alternative fuel for agricultural equipment such as generators, conveyors and farm machinery.
  • Alternative fuel for every diesel engine powered vehicle, burner train and marine vessel.
  • Used as a diesel fuel additive for the purpose of keeping the injectors, pumps and other combustion components clean.
  • Can be blended with petroleum diesel to reduce exhaust emissions.
  • Used as a lubricating additive to enhance engine performance.
