Project description:
RoKKa pursues the vision of rebuilding wastewater treatment plants into wastewater biorefineries by aiming to generate products of sufficient value and to make the processes economically viable and eco-friendly. RoKKa demonstrates the production of value added products with six pilot plants at the Wastewater Biorefinery Erbach. Nitrogen and phosphorus recovery is coupled with the production of bio-stimulants with microalgae. Carbon capture and usage to produce basic chemicals is piloted inside the gas stream of the combined heat and power plant. As a result of RoKKa, the environmental objectives of wastewater treatment plants can be analysed under multivariate aspects (water protection, bioeconomy, climate protection etc.).
We would like to thank the Baden-Württemberg Ministry of the Environment, Climate Protection and the Energy Sector and the European Union for funding the project "RoKKa" as part of the ERDF (European Research and Development Fund) programme "Bioeconomy – Biorefineries for the recovery of raw materials from waste and wastewater".
