An alternative product design and a cascade use are essential for the transition towards a circular bio-based economy, considering the increasing demand for timber products and the reduced roundwood volumes from climate-adapted forests. The transition requires a better understanding of recovered wood properties, knowledge about future material flows, the development of new and circular (recovered) wood products and buildings, and sustainability assessments to avoid misleading developments and rebound effects.
The presentation gives an overview of recently finished (InFutUReWood, KHoMaTe) and ongoing projects (TU&M, DUET, ISAR) at TUM’s Chair of Wood Science related to cascading and circular design. A model for the prediction of future recovered wood volumes is presented along with an environmental impact assessment of wood cascading taking temporal and market effects into account. Further, the results from inventory data modelling for assessing the building demolition phase will be presented. To complete the overview, three ongoing research projects are introduced.
