The main objective of the project is to demonstrate solutions that support the transition from a treatment plant for urban wastewater to a production unit of different valuables. So far waste water treatment plants are usually regarded as facilities to avoid emissions from wastewater. Current research and development shows that these plants can be converted and upgraded into production units to provide energy, nutrients, water for re-use and possibly other valuables. This is achieved by improved resource efficiency in the plant as well as new technologies and business models that allow the re-use of resources from the incoming water.
