Paper Title
Anaerobic Biodegradation of Brown Grease and Its Potential As A Source of Renewable Energy

Anaerobic digestion of brown grease (BG)–fats and oil collected from restaurants and similar food production facilities–is investigated. The purpose of the study was twofold. The first was to study the anaerobic digestibility and hence biomethane potential of BG. The second objective was to investigate the effect of adding dry hydrochar product to enhance the digestion process, especially as a possible in situ agent to improve biogas quality. Biochemical methane potential (BMP) tests were conducted to investigate the kinetics of BG digestion as well its ultimate methane potential. BMP tests involved various BG loadings between 3 and 30 g BG/L. Index terms- Anaerobic digestion, brown grease, renewable energy.
