Anaerobic digesters move into Oregon

Article Abstract:

Three digesters under construction in Oregon will process manure from local dairy cows to produce methane and agricultural soil amendments. All the digesters will have the ability to operate at thermophilic temperatures, and will separate anaerobically processed manure material into liquids and solids that have low to no Escherichia coli and Salmonella content and reduced nitrogen levels.

Adding value to composted manure

Article Abstract:

The Sustane Corporation in Bloomington, MN, has succeeded in gaining a good market share for Sustane, an organic fertilizer product recycled from poultry manure. The concern has gradually gained in stature from humble beginnings in 1989 and now boasts of regular exports of its fertilizer products to organic food producers in nations including France, Japan and Malaysia.
