CoMMunal wastewater as a source of ammonium nitrogen, hydrogen and bioplastics - the BüsNau biorefinery
The KoalAplan project is testing ways of making better use of the raw materials contained in wastewater and manufacturing marketable products using bioeconomic processes. At the Büsnau wastewater treatment plant, a process is being investigated that consists of chemical, physical and biological process steps and enables the targeted removal of the organic load from the wastewater. A new type of microscreen separates the particulate organic carbon directly after pre-treatment in order to produce hydrogen (H2) and raw materials for bioplastics in the side stream - the actual biorefinery. The planned combination of innovative processes can contribute to a more intensive circular economy and more climate protection.
