Extra methane production from municipal anaerobic digesters

Article Abstract:

Four residuals were studied at Marquette University to determine appropriate operating conditions for codigestion and analyze the economics in order to explore specific feedstocks and to evaluate high-strength wastes from breweries, fermentation companies and restaurants to gain extra biogas for renewable energy. The additional biogas potentially produced from yeast production waste alone can be employed to produce 16,300 kw-hr/day of electricity worth over $200,000.
