ANDIG 2: Factors that Affect Manure Digestion


This module provides information on factors that need to be managed in order to maintain biogas production. These factors – microbial population, feedstocks, loading rate, mixing, and environmental issues – determine the effectiveness of digester operation.

  1. Describe the role each factor plays in biogas production.
  2. Identify possible feedstocks for a digester
  3. Suggest possible loading rates.
  4. Identify tools that estimate biogas yield.
