Efficient energy production in modern biogas plants as an effective means of limiting CH4 and CO2 emissions

CH4 and CO2 are dangerous pollutants, mainly responsible for greenhouse effect. Energy production in the biogas plants can significantly reduce emissions of these gases into the atmosphere. This is possible because such plants use input renewable resources, whose lifecycle is almost CO2neutral, and organic wastes, if not properly treated, can produce CH4 emissions. This paper presents some examples of efficient energy production in the modern full-scale biogas plants, using innovative process engineering and instrumentation, control and automation techniques.
