On November 14, 2025, the Reuse Forum took place at the event center of Ruhr University. Representatives from research and practice came together to discuss current trends and developments in circular construction.

Prof. Peter Mark presented the Collaborative Research Center and emphasized the potential of modular reuse for sustainable building methods. Prof. Corentin Fivet (EPFL) showcased examples of successfully completed reuse projects, while Prof. Angelika Mettke (BTU Cottbus) provided an overview of three decades of research on reused precast concrete elements.
 
A key part of the program was the panel discussion featuring Prof. Corentin Fivet (EPFL), Prof. Michael Blaschko (Wayss & Freytag), Nina Baden-Wassmann (Schüßler), and Prof. Julian Meyer (Hochtief), moderated by Prof. Annette Hafner and Prof. Markus Thewes. The conversation made clear that reusing concrete components offers both technical opportunities and planning challenges, and that new business models will be needed. Central to the discussion was how recyclable components can be firmly integrated into planning. Standardization and modular construction systems play a decisive role here, as they enable reliable testing and certification of components. In addition, reuse-oriented construction requires clear processes and responsibilities – from material analysis to warranty. The participants agreed that this transformation can only succeed if it is supported on technical, economic, and social levels.
 
Going forward, the Reuse Forum will be held annually and aims to establish itself as a key platform for exchange within the circular construction sector. The next event will take place on November 20, 2026.
