Similarly to anaerobic digestion, though making use of different bacteria, composting is the aerobic decomposition of organic matter by micro organisms. It is however typically performed on relatively dry material rather than a slurry.

Instead of, or in addition to, collecting the flammable biogas emitted, the exothermic nature of the composting process can be exploited and the heat produced used, usually using a heat pump.
