Qualitative Analysis

Description of the Process

Greenmill produces 100.000 ton 2nd generation FAME/biodiesel (EN 14214) per year from waste streams. Worldwide an unique factory with a very high efficiency where waste streams from the process are minimized and converted into high-grade end products. For example the full heat capacity needed by the biodiesel factory and the accompanying tank farm (Tank storage Amsterdam, 100,000 m3) is generated from a waste stream. The used Potassium is converted to Potassium Phosphate, a product that can be used as fertiliser. Furthermore, very inferior fats can be upgraded in the build in purifying installation, before entering the actual biodiesel process.
