Deliverable D5.4 - Solution strategies to reach a non-toxic environment for 5 PM(T) uses from a system perspective and how they are perceived by the different stakeholders in the system

The Horizon 2020 project PROMISCES aims to increase the circularity of resources by overcoming barriers associated with the presence of PM(T)s in the soil-sediment-water system. To reach this overall goal one objective is the development of an integrated Decision Support Framework (DSF) to assist stakeholders in the risk management of PM(T) substances in the circular economy. This report provides an overview of the design and application of the DSF block "solutions to minimize the risk posed by PM(T) substances in the soil-sediment-water system" hereinafter referred to as the DSF Solutions module, using at least one of the five different substance-use combinations to demonstrate how systematic prevention, monitoring, risk assessment and treatment solutions will be evaluated. To illustrate how the solutions will be evaluated in the DSF, five substance-use combinations (PFBS, 6:2 FTS, PFBA, diethyl phthalate and galaxolide) and three circular economy routes were selected (Semi-closed water cycle for drinking water supply, Wastewater reuse for agricultural irrigation and Nutrient recovery from treated sludge for fertilizers). Overall, the application of the DSF Solutions module demonstrates the value of the DSF, as several starting points for solutions have been identified by using the framework.
