Anaerobic Digestion Biogas-potential Assay

Anaerobic digestion is a natural biological process that offers many environmental protection advantages. In the past, digesters were challenged by management difficulties and lack of profitability. Currently, there are six dairy farm digesters in Michigan, but the need for odor control, the income potential of the renewable energy digesters, and improvements in the technology and the understanding of operational principles are creating additional interest. This overview of anaerobic digestion on dairy farms includes a general cost analysis. Costs can often be offset by the recovery of byproducts when a digestion system is properly designed and managed
