Food and Fuel: Biogas Potential at Broward Dining Hall.

Web Abstract: 
Presents results of a study to determine biogas production and implementation potential at the University of Florida's Broward Dining Hall. Food waste quantity and current disposal methods were determined. The waste was analyzed for volatile and total solid contents and potential biogas yield. The dining hall produces an average of 262 kg of food waste daily. Food was digested in a daily-fed, daily-mixed anaerobic digester at a loading rate of 2 g VS/ L and a 30 day hydraulic retention time. The food waste produced an average of 0.5188 L biogas/g VS/day or a total average biogas potential for the dining hall of 39.8 m3/day. This gas would supplement the natural gas needs of the dining hall.
