Biogas in Europe

Europe lends itself to biogas production because of the commercial incentives and feedstocks available. Processing of small and large scale agricultural and food waste along with sewage and waste water allows for production of organic matter which readily breaks down to produce methane-rich biogas.

Coal mine methane
High concentration methane


Coal mine methane

Geotech has a range of analysers which can be used to monitor the gas extracted during mining, as well as assist in process and plant control. Coal bed methane, when directly drilled for, is released in high concentrations, which allows it to be used as a source of energy as opposed to becoming a harmful greenhouse gas emission. Measuring the quality of the methane being extracted is beneficial, particularly for carbon credit purposes and CDM projects.

Low concentration methane

Methane released from the worked coal face is diluted and removed by large ventilation systems so that the mixture does not become dangerous. The concentration of this ventilation air methane (VAM) is low, but the vast quantity of it has implications for greenhouse gas emissions. Systems are now developed to mitigate this, with methane analysis instrumentation available for the application.
