Crude Glycerine is a natural by-product produced during the biodiesel production process, specifically taking place during transesterification. Various methods for disposal and utilization of this crude glycerol have been attempted, including combustion, composting, anaerobic digestion, animal feeds, and thermochemical/biological conversions to value-added products.

We offer Crude Glycerine ranging from as low as 50% to as high as 95%. Most popular & widely used grade is CG 80% which means 80% of Glycerol & rest 20% is composed of water, methanol, MONG and ash.

Where does CG comes from?

Bio Diesel: Various Production Methods

There are three basic methods to biodiesel production:

  • Base catalysed transesterification of the oil
  • Acid catalysed transesterification of the oil
  • Conversion of the oil to its fatty acids and then to biodiesel.

Most of the biodiesel produced today is done with the base catalysed reaction. This catalyst being used splits the oil into glycerine and biodiesel.The glycerin produced at this stage is crude glycerin and is about 80% pure, but still contains contaminants like soap, methanol and water. In order to turn this crude glycerin into technical or pharmaceutical grade product, a or refining purification process must take place.
