The Innovation Cafés brought together stakeholders from Slovenia, Germany, Austria, Hungary, Slovakia, Czechia, Poland, Italy, and other partner regions, creating a platform for dialogue between innovators, research institutions, technical experts, and businesses working on sustainable construction solutions.
These events supported cross-border cooperation and focused on identifying practical pathways for scaling innovation, improving market uptake, and accelerating circular transformation in the construction sector.
Purpose of the Innovation Cafés
The initiative was designed to:
- Strengthen regional cooperation and exchange of knowledge
- Support innovation and practical collaboration in circular construction
- Improve market uptake of sustainable and low-carbon construction solutions
- Connect research, industry, and public stakeholders
- Identify barriers and opportunities for scaling circular and digital innovations
Key Innovation Themes Presented
Digital Construction and Material Traceability
Innovations included digital twins, materials management systems, digital tools for certification, and data-driven solutions improving traceability, transparency, and resource monitoring in the built environment.
Recycled Concrete and Circular Materials
Examples included recycled brick in concrete mixtures, low-carbon concrete optimisation, recycled aggregates, and solutions supporting reduced embodied carbon and improved material efficiency.
Bio-Based Construction Materials
Hemp-based insulation materials, hempcrete applications, and bio-based alternatives demonstrated strong potential for low-impact and circular building systems.
Waste-Based Material Innovation
Participants presented insulation panels from textile waste, waste-based concrete additives, and circular pavement materials developed to reduce landfill use and improve resource recovery.
Key Challenges Identified
Across the Innovation Cafés, participants highlighted several common barriers to wider adoption of circular construction solutions:
- Regulatory gaps and certification challenges
- Low market demand for circular materials
- Cost competitiveness and scaling barriers
- Limited digitalisation and interoperability
- Market acceptance of innovative solutions
- Need for stronger policy alignment and industry upskilling
Strategic Outcomes
The Innovation Cafés contributed to stronger understanding of how circular and digital solutions can support more sustainable construction systems in Central Europe.
They reinforced the importance of:
- Cross-sector collaboration between research, industry, and policymakers
- Wider adoption of secondary raw materials and low-carbon materials
- Integration of digital tools supporting transparency and efficiency
- Market validation and pilot-based innovation
- Knowledge exchange and stronger regional innovation ecosystems
As part of the ReBuilt legacy, the Innovation Cafés supported practical innovation exchange, collaboration, and clearer pathways for scaling circular and digital construction solutions across Central Europe.
