Monitoring landfill gas

Infrared absorption is usually the preferred method for measuring methane and carbon dioxide.  Most gases absorb radiation in the infrared region.  The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule.  These natural frequencies will depend on several factors. Thus different gas molecules have different natural frequencies and…

Optimising biogas generation in the UK and Germany

Methane makes money.  It generates energy revenues, carbon credits and is part of bio-treatment sludge processing.  In most of the world it has only just begun.  Measuring what we are doing and being responsible with this potentially damaging greenhouse gas makes good sense. With gas production for revenue, measurement is essential.  While landfill gas analysis…
