Circular (De)Construction Matchmaking:Towards a Morphological Matrix

Shifting from recycling toward reuse can accelerate the transition to a Circular Economy (CE) in the built environment. However, the large-scale implementation of reuse remains challenging. This research frames circular (de)construction reuse as a matchmaking problem, where supply and demand for reusable materials need to be matched. Currently, there is a lack of understanding of what fundamental dimensions that constitute matchmaking, and what options within each dimension are available to formulate a coherent matchmaking strategy. To address this gap, this research proposes a morphological matrix that tailors decision-making processes for circular (de)construction matchmaking across different assets and buildings. The matrix is grounded in literature insights and its functionality is illustrated through a user case. Different combinations of options can be selected from each dimension, widening the search for possible matchmaking strategies, and leading to innovative strategies that have not previously been identified. The study advances theoretical knowledge of matchmaking mechanisms and offers decision-support guidance for practitioners, bridging the gap between CE theory and implementation in the built environment.
