Focus releases updated digester case studies

From the introduction of the updated Wisconsin Agricultural Biogas Casebook:

Wisconsin remains at the forefront of U.S. farm-based digester use. This second edition of the Wisconsin Agricultural Biogas Casebook includes brief case studies of farm-based anaerobic digesters installed in Wisconsin. This report gives a look at the experiences of 21 farms with operating anaerobic digester systems in Wisconsin as of fall 2009. The author extends a special thanks to the digester owners, operators, designers and utility representatives who have graciously shared their experiences, time and information to make this casebook possible. This information is presented to give those interested in digesters some insight into how these systems are working in Wisconsin. The task is made easier by the fact that these systems appear to be generally successful. When relevant, insights, problems, mistakes or other issues encountered by the parties involved are shared in the hope that future efforts can benefit from that history.
