What is biodiesel?

Biodiesel is made up of monoalkyl esters of long chain fatty acids derived from vegetable oil or animal fats. This feedstock is converted, by trans-esterification, into biodiesel.

It can be used pure or blended with diesel. Biodiesel blends are usually denoted by BXX, where “XX” indicates the percentage by volume of biodiesel in the blend.

Switching to biodiesel is a breeze as no engine modification is necessary. Since March 2006, Alpha Biodiesel has been used in over 200 vehicles. Alpha Biofuels’ users have positive feedback and significantly lower emissions.

Benefits of Alpha Biodiesel

  • Compatible with all diesel engines
    (No modifications needed)
  • Less black smoke
  • Less carcinogenic emissions
  • Biodegradable
  • Non-toxic
  • Non-flammable
  • Reduced greenhouse gas emissions
  • Does not compete with food crops for feedstock


Biodiesel & Fuel Filters

Biodiesel has some solvent properties and will act as a solvent in the fuel. Blends greater than B20 may have enough of a solvent effect to break down the varnish deposits on the walls of the existing fuel storage tanks or fuel systems.The break-down of these varnish deposits will contaminate the fuel with particulate, which can cause fuel filters to plug rapidly.Once the contaminant is removed from the fuel, subsequent fuel filter service intervals should return to normal.

Filter plugging problems can be prevented by effectively cleaning storage tanks before introducing biodiesel. It is also recommended that filter used should have solvent resistant sealing materials.
