  • Biogas is a mixture of methane and carbon dioxide. It is produced by the microorganisms under anaerobic conditions. Its main sources are agricultural materials and by-products or residues of agri-food industry, which can be used in the methane fermentation process. This widely distributed in nature process takes place  for instance in bogs or swamps, on the bottom of the sea or in the stomachs of ruminant animals.

    The use of biogas

    The  technologically derived biogas is widely applied for utility purposes.  In the world it is used as a fuel for electric power generator, as a heat source and as a motor fuel after purification and compression (CNG systems).

    Biogas Power Plant

    Biogas plants are very specific installations. The type of selected biogas production technology is chosen on the basis of materials, which will be use in it and considering the individual conditions on farms. However, for the farms and factories biogas production is solution that gives a lot of advantages – it allows waste management, energy and heat production.

    The future of biogas plant

    When most people think about renewable technologies, the first ideas are wind, solar and water plants. In addition to them, there are other   technologies, that have a chance to become very popular on the market.  Generation of energy from biogas is one of them. This technique become very promising and it is still intensively developed. The support for this method is increasing continuously.

    “Producing 100 per cent renewable energy from our biodegradable waste helps tackle climate change, instead of contributing to climate change through landfilling and incineration”

    Friends of the Earth (2009)

    “Anaerobic digestion can help us to replace fossil fuels, reduce methane emissions from landfill sites and increase the efficiency of our energy system. As well as helping us to fight climate change, it can solve many of our waste management problems, reduce freshwater pollution from organic wastes, increase fuel security and reduce our dependence on chemical fertilizers.”

    Greenpeace UK (2009)

    “Odor elimination and a separated effluent that is easier to transport and spread than raw manure are key benefits. Stabilization of pathogens and nutrients makes anaerobically digested effluent safer and less likely to damage surface water quality. Prevention of greenhouse gas emissions is another advantage. “
