The goal of the project is to develop affordable digesters for the majority of U.S. livestock farmers. To achieve this goal, six small-scale digesters, with two operational designs will be studied to provide long-term research on a system that has not been fully explored. Treatment efficiency, capital and operational costs, and gas utilization strategies will be evaluated for each type of system. Costs and benefits of different treatment strategies will be compared to existing manure management practices.
