| Summary: | Within the joint project RePhoRM, a technological and organizational joint solution for phosphorus recycling in the Rhine-Main region is being developed and implemented. Based on the mono sewage sludge incineration capacity and its potential expansion in the FrankfurtRhineMain metropolitan region, a cooperative phosphorus recovery from sewage sludge ash is to be implemented. |

| Summary: | Water management in Germany is neither resource-efficient nor does it meet demand. The project centres on flexible, efficient and robust water supply systems of the future, in which modules and components act autonomously within a predefined framework. When the cyber-physical agents communicate with each other in the cyber-physical water market economy to be designed, future performance promises will be remunerated with “money”. The market-inherent resource and allocation efficiency enables efficient, resource-saving solutions. Building on this, the cyber-physical water market economy is to be validated and implemented in a real demonstrator system. |

| Summary: | Nitrous oxide (N2O; laughing gas) is a potent greenhouse gas and ozone depleting substance. Over the last century the atmospheric concentration of N2O has been constantly on the rise as a consequence of the invention of man-made nitrogen fixation (the Haber-Bosch process) and intensification of agricultural fertilization practices that resulted in a severe anthropogenic imbalance of the global biogeochemical nitrogen cycle. Despite the fact that N2O emissions have been recognized to play an important role in climate change, corresponding mitigation strategies remained underexplored. The aim of this interdisciplinary and collaborative project is to investigate N2O respiring bacteria (NrB) and their applicability to mitigate N2O emissions from wastewater treatment plants. The two main objectives are (i) to identify the best-suited NrB for the task and (ii) to expose these organisms under continuous conditions that are realistic for wastewater treatment. The work program includes a thorough microbiological characterization of representative NrB in short-term batch experiments including scrutiny of nitrous oxide respiration towards the presence of dissolved oxygen and other relevant factors such as carbon source and impact of the wastewater matrix. Suitable NrB will be exposed to wastewater-like conditions in continuous long-term experiments. These trials will be performed in lab-scale reactors under varying conditions, e.g. dynamic changes in the dissolved oxygen concentration. The project will provide a suitability assessment regarding the use of NrB under wastewater conditions and the implementation of NrB in wastewater treatment systems. It will also contribute to exploit the almost untouched natural resource of N2O respiring bacteria. |

| Summary: | Groundwater is the key water resource for the Frankfurt/Rhine-Main metropolitan region. However, the quality of groundwater is at risk and the amount of water available in the growing region is also becoming scarcer. The WaRM project aims to reduce the potential for conflict over water resources by investigating suitable measures to increase water supply and quality and to improve water use efficiency. To this end, a water system model of the Frankfurt/Rhine-Main metropolitan region will be developed, which will be used to analyze the effects of measures, taking into account possible future scenarios. |
