BIOGAS IS OUR FOCUS FOR OVER 20 YEARS WE HAVE BEEN INVOLVED IN THE DEVELOPMENT OF EFFICIENT BIOGAS PLANTS
How can agricultural waste products be utilized profi tably? Stefan and Norbert Sauter, managing directors of Sauter Biogas GmbH, were presented with this question from an early age. Their parents – having run a farm successfully – had devoted their attention to biogas utilisation since the late 1980’s. This in turn inspired the brothers and the generation of biogas both in theory and in practice which has been a solid part of their lives ever since. The Sauter farm has been operating its own biogas plant since 1992. Based on their plant experience with stirring systems the brothers set out to achieve a goal: to develop a digester without internal technical components. Driven by this idea numerous experiments followed. At the same time the Sauters developed a vision of being able to process a variety of residues. Following years of research, the fi rst biogas plant with the groundbreaking and patented‚ ’Sprinkled, not stirred!’ system was set up in 2006. Meanwhile, Sauter Biogas GmbH has built 43 plants from 75 kW to 4 MW in Europe, America and Africa – 33 of them are in Germany (Nov. 2015).
