Abstract
The concrete industry in the Ruhr region faces critical challenges, including primary raw material shortages and the need to reduce anthropogenic greenhouse gas emissions. Immediate action is essential as primary resources remain necessary even with secondary raw materials being used, and cutting emissions is crucial to mitigate climate change. This research proposes that establishing a Resource-conserving Concrete Hub (RCH) can positively affect the image and efficiency of Resource-conserving Concrete by unifying key stakeholders and integrating new participants. The Ruhr region, with its dense population, rich industrial history, and polycentric structure, seems to provide an ideal setting for implementation. Although current data on urban mining is insufficient for precise planning, as a material registry has not been implemented yet, the study identifies promising locations, particularly the Essen city harbor, as prime candidates for advancing the RCH concept and therefore boosting urban mining practices within Germany.
