Through two online challenge-based events, participants collaborated to address practical questions related to digital tools, circular business models, and sustainable transformation in the construction sector.
The Circathon created a platform for interdisciplinary exchange, creativity, and applied innovation, supporting stronger engagement between technical experts, innovators, and future solution developers.
Key Challenge Themes
CinderOSS Platform Development
The first challenge focused on exploring opportunities for improving and adapting the CinderOSS digital platform, supporting circular construction workflows, material exchange, and digital collaboration across value chains.
Circular Business Model Innovation
The second challenge addressed business-oriented solutions, encouraging participants to develop models that could support market uptake, economic viability, and practical implementation of circular construction ideas.
Strategic Value for ReBuilt
The Circathon demonstrated how collaborative innovation processes can support practical development of digital and circular solutions within the built environment.
It reinforced the importance of:
- Innovation-driven problem solving
- Digital tools supporting circular construction
- Business model development for market uptake
- Cross-disciplinary collaboration
- Practical pathways for scaling circular solutions
Winning concepts such as Swisscular and ReConstructors highlighted the potential of challenge-based approaches to generate innovative ideas relevant to circular construction ecosystems.
As part of the ReBuilt legacy, the Circathon contributed to stronger innovation culture, co-creation, and entrepreneurial thinking supporting circular and digital transformation in Central Europe.
