  Document BAE-1747 Anaerobic Digestion of Animal Manures: Understanding the Basic Processes

By Douglas Hamilton. The process of producing methane from manure is fairly straight forward—seal manure in an airtight container and it will form biogas, which is a mixture of methane (CH4), carbon dioxide (CO2) and trace amounts of other gases. However, behind the apparent simplicity, lie complicated interactions involving several communities of microorganisms. Revised February 2014.

  Document BAE-1750 Anaerobic Digestion of Animal Manures: Types of Digesters

By Douglas Hamilton. All anaerobic digesters perform the same basic function. They hold manure in the absence of oxygen and maintain the proper conditions for methane forming microorganisms to grow. There are a wide variety of anaerobic digesters, each performing this basic function in a subtly different way. Seven of the most common digesters are described in this document. Revised February 2014.
