Biogas is combustible gas derived from decomposing biological waste in the absence of oxygen (anaerobic digestion).
Biogas can be produced from wet or mixed organic waste streams (biomass). The anaerobic digestion conversion processes utilise natural occuring microbes and biochemical pathways to convert waste into biogas. During anaerobic digestion, around half of the carbon content of the biomass is converted to biogas, which can be directly used in a burner/condenser or fed into a gas engine to produce electricity and/or thermal energy (heat). The rest of the biomass becomes organic slurry which can be used directly as a fertiliser or separated into a liquid and solid phase to produce animal bedding/soil conditioner, liquid fertiliser and recycled water.
Biogas technology is a generic term for the technologies associated with the anaerobic digestion of organic waste (food waste, animal waste, sewage etc) to produce methane gas and an organic sludge (a recyclable by-product). Biogas technology is widely acknowedged as the best way to treat wet organic waste. Farm owners, food processors, waste managers and sewage treatment plant operators can all benefit from treating their organic waste streams with biogas technologies.
