Abstract
The Pro-Reuse project is developing a framework to advance automated, data-driven circular deconstruction and reuse of concrete components. The project uses a process ontology-based approach to create structured, interoperable and machine-readable knowledge covering the entire life cycle of concrete elements, from material detection and extraction to quality inspection and reintegration into new structures.
The framework addresses key technical and organisational challenges of comprehensive documentation of (de-)construction process, certification and assessment of concrete components for reuse. Furthermore, it focusses on the development of a transparent Circular Life Cycle Sustainability Assessment (C-LCSA) as well as digital product passports. Core activities of the project include defining data requirements, classifying circular pathways, and encoding sustainability and circularity concepts in a machine-readable ontology to ensure consistent use across digital tools. Complementary non-invasive testing strategies, multimodal sensor data and resistance prediction models enhance the reliability of reclaimed component qualification.
A prototype system integrating data collection and an ontology-based assessment method will be validated at the CARE*Site. By enabling traceability, recertification, and scenario-based sustainability evaluation, the project directly contributes to the goals of climate neutrality and resource efficiency while supporting the wider adoption of circular construction practices.
