The following profiles highlight operations, lessons learned, and case studies of farm-based anaerobic digesters throughout the United States. As farm-based anaerobic digestion continues to grow, we can learn from past successes, challenges, and opportunities.

Operating Project Profiles
AgSTAR develops brief profiles of farm-based anaerobic digestion systems located throughout the United States and tracked in AgSTAR’s project database to promote activities across the country.

Dormant Project Profiles
AgSTAR collects information on several closed facilities. As the use of anaerobic digesters continue to grow and evolve in the United States, closed facilities can offer lessons learned to those operating or planning for anaerobic digestion on a farm.

Other Project Case Studies
AgSTAR and other anaerobic digestion stakeholders have developed additional case studies with information on operations, outputs, benefits, challenges, and opportunities to further support understanding of anaerobic digestion projects on the farm.
