The biogas digester is the system component where the
animal, human and other organic wastes are introduced, usually as a
slurry with water, to break down anaerobically.
A storage container is used to hold the gas produced, from which it is piped for burning as a fuel. Variable volume storage (i.e. flexible bag or floating drum) is easier, cheaper and more energy efficient than high pressure cylinders, regulators or compressors.
When the digester is emptied, the spent effluent is dried for later reuse as a fertilizer.
