Dairy resolves issues and produces power for the facility
Bettencourt Dairies discovered a solution that would allow them to resolve the odor and methane issues, while also producing power for the facility and the local grid. Six one-million-gallon anaerobic digesters were installed at Rock Creek Dairy to process manure and mitigate odors. Approximately 200,000 gallons of cow manure are collected daily, pumped through a nearly mile-long pipeline to the digesters and processed into clean compost used for animal bedding. It’s the largest facility of its kind in the country. One of the generators runs continuously while the other unit runs variable hours following biogas production. Both feed power to an electrical transformer located outside the building. Exhaust heat from the engines is used to heat the six digesters.
