Abstract
In the context of CE, a key challenge for implementing cascading practices across industrial sectors is the lack of dominant circularity- focused categorical meanings within markets. Our categorization of wood-based markets according to R-imperatives addresses this gap by revealing their capacity to capture and retain the value of PMCs within and across industries, thereby extending cascading chains and uncovering previously overlooked market segments. In doing so, the analysis shows that ~40% of wood-based sector markets come with potential for cascading. These interconnected markets form cascading pathways, indicating not only potential synergy effects but also areas of market competition that may act as barriers to implementation. By identifying these patterns, our market categorization offers a structural lens to guide governance interventions aimed at optimizing the circular allocation of PMCs.
