With consideration to the crude glycerol surplus driven by the growth in biodiesel manufacturing, alternative uses for biodiesel derived glycerol have become increasingly essential. Anaerobic digestion of the glycerol reduces the chemical oxygen demand of the glycerol waste product, while capturing biogas as an energy source that can be used on site to reduce heating cost at a biodiesel facility. In this thesis, kinetic parameters are extracted from batch experimental data and applied to steady state equations. A flow sheet for the application of anaerobic digestion to biodiesel derived glycerol is developed and explored. The economic analysis of the scenario tracks the capital cost, operating cost, and savings associated with implementing the system.
