About Us

Northern Biogas brings experience and proven design practices to the relatively new world of organic solids-based energy production. We have become an industry leader because we are an effective innovator, and custom solutions provider. Having installed the most effective, efficient methane digester systems in the area means that we are constantly looking for innovation and improvement, but always with an eye on solid engineering practices and long-term value.

Northern Biogas was formed by a group of professional Wisconsin Dairy Producers, licensed engineers, project managers, and licensed wastewater treatment operators to build and manage biomass renewable energy projects. The underlying philosophy of Northern Biogas is to provide a reliable and affordable anaerobic digester that can offer a means of managing waste and odor while providing an economic value to the client and community.


Guy Selsmeyer P.E.

Prior to Northern Biogas, Mr. Selsmeyer was a partner of Green Valley Dairy, a 3,700 cow dairy built in 1999. In 2005, Mr. Selsmeyer helped to design and build an anaerobic digester to help facilitate in manure and nutrient management while generating 600 kW of power to sell to the local electric company.  This led to the creation of Northern Biogas.  He is intimately familiar with all aspects of anaerobic digestion and electric generation from biogas as well as the needs of large-scale agriculture.  He has presented on the subject at multiple symposiums, including ASABE, AGSTAR, Wisconsin Focus on Energy, and National Biocycle Conference to name a few.
