The methane containing biogas would rise to the top of the container; the user would extract the gas as needed for cooking and heating. The digested sludge or digestate would be removed and employed as fertilizer.
Biogass Renewables uses a process called anaerobic digestion to convert commercial and industrial waste into onsite electricity, heat and clean methane gas.
