What is Anaerobic Digestion?
Anaerobic digestion is a biological process whereby bacteria break down organic materials
such as animal manure into biogas in the absence of oxygen.  Biogas from a digester consists
mainly of methane (60-70%) and carbon dioxide (30-40%).  Biogas is used as a fuel to produce
electricity for farm use and/or for sale. Biogas can also fire a boiler to produce a source of
heat. Excess biogas must be flared for safety odor control. Go to

Good question, here's the place to start working on an answer.  AURI, Minnesota funded the
development of a self screening document to assist potential digester owners in assessing
whether a digester makes sense on a farm.
