Production Process

The process of making biodiesel consist of different steps. The used cooking oil is first being purified and refined, which brings back the acidity to an FFA of max 2%. The next step is to transfer the oil into biodiesel. This process is called esterification. During the production process of biodiesel, methanol and a catalyst are being added to the oils and fats, due to that the glycerol of the oils and fats is exchanged for methanol. Two products are made by this process:

Biodiesel ( main product)
Glycerine (by product)

The biodiesel in blended into the standard diesel. In 2020 the aim will be to blend in 10 %. The glycerine is a by-product and can be used as a raw material for the bio digester.

Raw materials

Depending on the production for 1st or 2nd generation bio fuel the following raw materials can be used:

  • Used cooking oil ( 2nd generation)
  • Animal fat Kat.1 (2nd generation)
  • Soy oil (1st generation)
  • Corn oil (1st generation)
  • Palm oil (1st generation)
  • Rape seed oil (1st generation)
