Mother Nature has a Game Plan - Biological Stabilization Manure is partially digested feed. The remaining partially degraded and unused materials continue to decompose upon leaving the animal. Bacterial decomposition begins in any manure containment and continues until the manure is removed or it is stabilized. In todays world, odor control, pathogen control, costs and nutrient management are important when selecting manure management system components. An anaerobic digester is a structure where the goal is continuous methane production and a biologically stabilized effluent.
Digesters reduce odor generation and migration.
Digester effluent does not release effusive objectionable odors. The effluent of a digester has an earthy smell with some ammonia present. Both farms were located within sight of clusters of non-farm residences. Both were located within a mile of towns and subdivisions. Valley Pork had an acute odor problem prior to installation of the digester system.
