We have entered a new field of application of anaerobic technologies with the realization of the Csengersima biogas plant. The fermenters with mesophilic operation, built from modular stainless steel elements, are equipped with a highly efficient mixing system and can ensure the planned biogas yield. The raw materials of the biogas plant are Csengersimán cattle litter, liquid cattle manure, dairy waste water, corn husk and corn silage. The facility that is already in operation uses 230-280 Nm3/h of biogas per hour to produce electricity during hours favorable for electricity sales.
