A methane-rich gas forms when organic material decomposes under anaerobic conditions. Landfill gas forms, for instance, at landfills, and biogas forms in AD plants, in sewage treatment plants and where organic waste is processed.

Methane-rich gas can be collected and used to manufacture electricity and/or heat, and it can be upgraded to make methane fuel for vehicles.

Mannvit has designed a system to collect landfill gas, has designed upgrading plant for the manufacture of methane fuel, as well as underground transport pipe systems and refuelling stations. Mannvit provides advice on the purchase and installation of power plants that use landfill gas. We have also developed models to assess gas formation, executed tests at landfill sites to assess gas formation, provided advice as regards to technical solutions for the treatment of gas, assisted in purchase and operation and performed risk assessment as regards to explosion risks.

Utilization of methane is eco-friendly
