Abstract: Biogas is produced by anaerobic digestion of organic matter in digesters, which must be stirred. Stirring is responsible for up to 54% of the power consumption of current biogas plants [Dachs; Rehm 2006]. One possibility to operate biogas plants more efficiently is to reduce the energy consumption by avoiding constant stirring.
