The PPM biodiesel technology is based on the approved process of transesterfication of fatty acid glycerides in an alkaline environment. Liquid prefabricated potassium methylate is added as catalyst.

The actual process is preceded by the pre-cleaning of the raw material. The pre-cleaning contains the filtration, drying and reduction of the share of free fatty acids in the oil.

The actual process consists of 4 main stages:

  I. Transesterification in two stages
 II. Solubilisation (product washing)
III. Distillation of methanol and water
IV. Adding of special ingredients
