The potential for recovering energy via anearobic digestion of byproducts has been investigated for the brewery industry. This process takes advantage of the anaerobic bacteriological production of methane, which can be collected and used as a clean-burning fuel. Based on laboratory-scale experimentation to develop design parameters, a cost analysis was performed to evaluate the feasibility of this method of providing energy. The results indicate that the process is economic and will provide methane fuel gas at a competitive price when the value of the by-product is –154/metric ton and when the biomass recovered from the digester can be sold at –242/metric ton.
