Fermentation

Anaerobic fermentation is an oxidation process, in which organic compounds, such as e.g. livestock manure and toilet waste, are converted by microbiological processes in absence of oxygen (O2) to methane (CH4) and carbon dioxide (CO2). The produced bio-gas (~ 55 - 75% CH4) can be used for cooking, heating and light. The methane production contributes to the BOD reduction in digested sludge. It is possible to apply high loading rates to the digester and even recalcitrant materials (e.g. lignin) can be degraded.
