Könnern Biomethane Refinery

The Könnern industrial zone between Magdeburg and Halle, Germany, is home to one of the world's largest biogas parks with gas feed-in. The biogas park consists of four modules, each of which comprises four digesters, four digestate storage tank and a slurry storage as well as a technical building with a separator, a central pump unit and a compressor for the biogas. The bundling of the technology in modules creates synergies and boosts the efficiency. The demand for fresh matter, which amounts to approximately 120,000 t a year, is supplied by about 30 farmers in a vicinity of approximately 15 kilometres and can be stored on site on a paved storage platform with a total area of 2,7 hectares.
