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 below. In-depth profiles of select projects are available here.
