A sophisticated concept with optimal substrate composition, adapted to regional conditions and customer requirements, is what we regard as the basis for any biogas project. Choosing the best process technology, from both a technical and economical point of view, depends largely on the input material. Krieg & Fischer has extensive experience with one-stage, two-stage and multi-stage, mesophilic and thermophilic wet and dry fermentation biogas plants. We know how to evaluate the various substrates coorectly – all kinds of liquid manure (animal excrement), biowaste, kitchen and catering waste, sludges, etc. for your biogas plant.
