The first-of-its-kind in the nation renewable natural gas (RNG) offloading station at Dane County, Wisconsin’s landfill today received its first load of RNG from a manure digester in the Yahara Lakes Watershed. Brightmark has completed construction of the multi-million-dollar project upgrading gas equipment at its digester northwest of Waunakee in the Town of Vienna. The biogas converted from 90,000 gallons of manure per day will be trucked to the county’s offload station from the digester project. The digester captures methane and phosphorus from manure, which reduces greenhouse gas emissions and harmful runoff to lakes and streams. The digester’s biogas will be injected through the county’s equipment into the interstate transmission pipeline so it can be used as renewable fuel, powering fleets of RNG vehicles across the United States.
