  • Energy from biogas

    From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...

  • Case study - 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 has been required for compliance with ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...
