Crude Glycerine

Crude Glycerine is a co-product generated during the biodiesel manufacturing process, primarily occurring through transesterification. For every 100 pounds of biodiesel manufactured, nearly 10 pounds of crude glycerol are formed. Multiple approaches for handling and utilizingthis crude glycerol have been explored, including combustion, composting, anaerobic digestion, animal feed applications, and thermochemical or biological conversion into value-added products.

Origin & Process

The Origins of Crude Glycerine

Biodiesel: Key Production Methods

The majority of biodiesel produced today uses a base-catalyzed reaction process. In this method, the catalyst separates the oil into biodiesel and glycerine. The glycerine obtained at this stage is crude glycerine, typically around 80% pure, and contains impurities such as soap, methanol, and water. To convert crude glycerine into technical or pharmaceutical grade glycerine, further refining and purification are required.

Impurities present at this stage:

  • Methanol
  • Water
  • Soap

There are three primary methods of biodiesel production:

  1. Base-catalyzed transesterification of oils
  2. Acid-catalyzed transesterification of oils
  3. Conversion of oils into fatty acids, followed by biodiesel production
