Manure from several farms can be transported & processed at a common location
Extra trucking costs of manure to digester & return of digestate as fertilizer to partner farms
Host farm or separate site for processing must be located at a suitable injection location
Biogas and/or manure pumping via underground plastic lines is a possible option (within limited distances)
