Unlike traditional biodiesel technologies, SBI’s revolutionary proprietary heterogeneous catalyst based fixed bed trans-esterification technology (patent pending) utilize non consumable catalysts and complete trans- esterification in a single pass. Unlike traditional technologies, it can handle high to full free fatty acid feed stocks to produce ASTM grade biodiesel and high quality, high value colorless glycerol.  It does not produce any waste materials. This  technology recovers and recycles methanol and energy efficiently, requires smaller foot prints, smaller capital costs, fully automated,  minimizes manual handling, therefore, it is greener and environmentally friendly.
