Electricity and fertilizer from Otelfingen Kompogas Facility for treatment of biowaste
In the Otelfingen Kompogas facility, approximately 13,000 tonnes of biowaste are treated annually producing 1.7 GWh electricity- among other products - through anaerobic thermophilic fermentation. The declared products in the reference year 2017 are:
1 tonne of biowaste treated
1 kWh of net electricity generated and thereafter distributed to a customer connected to the local distribution network
1 kWh of heat generated
1 tonne of liquid fertilizer (press water) produced and thereafter distributed and applied in agriculture
1 tonne of solid fertilizer (residue) produced and thereafter distributed and applied in agriculture
Axpo Kompogas Ltd. has become a global player in energy recovery via dry fermentation of organic wastes and biogenous materials. Axpo Kompogas Ltd. is fully consolidated within the Axpo group. The fermentation of biomass with the Kompogas process and subsequent conversion of raw biogas into electricity is an important pillar of the Axpo strategy to develop new renewable energy resources.
