ARTICLE : Biogas Project at PRI Sunshine Coast

Biogas is extracted from many raw (organic) materials in nature besides human and animal manure: leaves, twigs, grasses, garbage and agricultural and industrial wastes with an organic content greater than 2%.  Biogas can be used for cooking, lighting (gas lamps), to generate electricity, as fuel to operate cars and other machinery and other energy needs. Biogas is a form of energy produced by anaerobic digestion (the decomposition of constituents of biodegradable matter in an oxygen-free environment). It is a mixture of gases, mainly carbon dioxide and methane. It consist of around 55-65% Methane, 30-35% carbon dioxide, 1-5% water vapour, 0-3% hydrogen sulphide and 0-1% hydrogen.
