PRODUCING ELECTRICITY FROM METHANE

Biodigesters recover methane from animal manure through a process called anaerobic digestion.

  1. Receiving Tank - collects organic waste such as manure, plant and food waste.
  2. Biogester - Anaerobic bacteria 'digest' organic material in the absence of oxygen and produce biogas.
  3. Combined Heat and Power Unit - Biogas is burned to power a steam generator that produces electricity.
