Subitec develops integrated processes in which CO2 from exhaust gases from industrial combustion processes are used for the cultivation of algae. After extracting high valuable substances remaining biomass can be fermented to biogas which provides electricity and heat in combined heat and power stations. Hereby released exhaust CO2 can be recycled and utilized for the cultivation of algae. Residues of one plant can therefore serve as resource for the other. The closed cultivation system allows for the circulation of water and nutrients. The biomass refinery concept permits thorough exploitation of algal biomass.
The complete utilization of the biomass refinery concept can be expanded on multiple cooperating companies. At this point, Subitec offers the added value of merging the various interests.
