Process of biogas production is aerobic process or anaerobic process? Bacteria involved in the process is aerobic or anaerobic?
The biogas plant receives all kinds of organic waste - typically livestock manure and organic industrial waste. The dry solid in livestock manure contains carbon, among other things, and in the process this carbon is transformed into biogas, a compound of methane (CH4) and carbon dioxide (CO2).
The manure and waste are mixed in the plant's receiving tank before being heated to 38-52°C/100-125.6°F and pumped into the digester in which the biogas is produced. The biomass stays in the digester for 2-3 weeks and the fermented slurry can subsequently be used as crop fertilizer. This fertilizer has improved qualities such as less odour inconveniences when spreading the slurry and significant reduction of green house gasses.
