Operating Anaerobic Digester Projects
As of November 2013, AgSTAR estimates that there are approximately 220 anaerobic digester systems operating at commercial livestock farms in the United States. Updated information and analysis of the digester systems is underway and will be available soon. The AgSTAR database provides more detailed information about operating projects.
Farm Project Profiles
Anaerobic digester systems can be installed successfully at operations that collect manure as a liquid, slurry, or semi-solid. Existing farms use a variety of different types of digester designs and energy use technologies. Details about operating projects can be reviewed by clicking on a map marker in the above map or the full list of operating projects is available here (XLS) (91K, Download XLS Viewer ). In-depth profiles of select projects are available here.
