Profiles and Case Studies

You can filter, sort, and search for project profiles and case studies in the table below. Operating systems provide working examples of success, and projects that have been shut down offer lessons learned. The case studies often highlight multiple anaerobic digesters.

Pursuant to 5 CFR § 2635.702(c)(2), names are displayed here as the result of recognition for achievement given under an agency program of recognition for accomplishment in support of the agency’s mission. Any reference to a specific company or commercial product or service by trade name, trademark, manufacturer, company, or otherwise does not constitute or imply the endorsement or recommendation of EPA.
