Agraferm Technologies AG, which is based in Pfaffenhofen, Germany, designs and builds Anaerobic Digestion plants. It is one of the few full service providers of turnkey agricultural and industrial biogas plants in Europe, which operates internationally.

The facility will use about 50,000 tonnes p.a feedstock (~ 60/40 liquid/solid) to generate biogas through an anaerobic digestion process and the biogas then acts as the fuel for a combined heat and power unit to produce electricity that is to be fed in to the National Power Grid.
The liquid and solid digestate also produced by the process will be used as an odour free, nutrient rich fertilizer and returned to the fields to the benefit of the next year’s crop.
