Co-digestion Model

CH4 Biogas plants produce renewable energy by anaerobically digesting livestock manure and food-grade organic wastes. Our partner, Bigadan A/S, pioneered the co-digestion concept that has been the operating model for the Danish biogas industry for over 25 years.

CH4 Biogas

Paul Toretta, Bob Blythe and Bigadan A/S formed CH4 Biogas, LLC in 2008 in response to market demand for anaerobic digestion and alternative energy in the United States.
