META-SETS

The goal of this project is to develop an overarching data management and monitoring framework for sustainably scaling circular economy practices in the built environment to the urban level, by locally testing and implementing the framework across multiple European use cases in Sweden, Belgium, Italy and Finland. The project will collect, analyze, and share data on material flows and waste fractions in urban construction projects by developing a resilient data management framework for tracing and monitoring material flows in a digital twin environment. Through simulations, the digital twin supports sustainability by evaluating low-emission routes and resource-saving strategies before the real-world deployment. By merging spatial, temporal, and environmental data, each city can tailor solutions to local regulations and needs, ultimately supporting shared, data-driven decision-making and paving the way for more resilient and sustainable urban systems.

The production of new knowledge is critical for developing an adaptable framework that reflects the diversity of urban environments. The project contributes by showing how steering and reinforcing collaboration of stakeholders and companies active in the recircularization of the construction sector can be organized. This project will provide actionable tools and frameworks that empower cities to implement efficient circular economy practices, enhance policy development, and support sustainable urban management, while serving as a scalable model for comparative assessment, benchmarking, and translation into resilient policy shifts. Outputs include city-specific digital twins, material flow maps, and decision-support tools integrating spatial, temporal, and environmental data. Expected impacts are increased material recirculation, reduced waste, optimized reverse logistics, and lower emissions. The results will also open opportunities for commercialization and continued development of the framework and tools, enabling broader market uptake and sustained innovation beyond the project’s duration.
