Roadmap

1

THE CHALLENGE WE ADDRESSED

The construction sector remains one of the most resource-intensive industries in Europe, accounting for over 50% of extracted materials, significant water and energy consumption, and more than one-third of total waste generation and greenhouse gas emissions.

At the start of the ReBuilt project, these challenges highlighted the urgent need to accelerate the transition toward circular, resource-efficient, and digitally supported construction practices.

Through ReBuilt, partners worked to address these systemic barriers and support the uptake of secondary, recycled, and bio-based construction materials across Central Europe.

2

KEY BARRIERS IDENTIFIED IN CENTRAL EUROPE

ReBuilt identified several common barriers slowing down the transition to circular construction across Central Europe:
- Limited market acceptance of secondary raw material (SRM)-based products
- Insufficient traceability, quality assurance, and reliable material data
- Fragmented legal and administrative pathways for reuse and End-of-Waste implementation
- Limited examples of scalable circular economy business models
- Weak cross-border cooperation and lack of specialised training opportunities
- Logistic and supply-chain challenges related to collection, separation, and transport of recyclable materials
- High quality and procurement requirements limiting the use of recycled construction products
- Low public confidence and limited practical experience with circular and bio-based materials

By mapping these barriers, the project created a stronger foundation for practical solutions and regional collaboration.

OUR APPROACH

ReBuilt promoted a shift in mindset — from linear construction practices toward circular, digital, and resource-efficient building systems.

The project combined innovation, cooperation, training, and digital tools to connect stakeholders across the value chain and demonstrate that circular construction can be practical, scalable, and economically relevant.

ReBuilt the Mindset. ReBuilt the Future.

WHAT REBUILT DELIVERED

ReBuilt translated transnational cooperation into practical results supporting the transition towards circular and digital construction in Central Europe.

Training and capacity building

The project developed and pilot-tested a joint cross-national training programme, including a Massive Open Online Course (MOOC). The programme provided educational materials and learning opportunities for construction professionals, businesses and other stakeholders seeking to strengthen their knowledge of circular and digital construction practices.

Technical and digital solutions

ReBuilt developed and tested technical and digital solutions addressing practical challenges in circular construction. Technical pilots explored the application of circular materials and construction approaches, while digital pilots tested tools supporting information management, transparency and traceability. The results provided practical references for the wider adoption of circular and digital construction solutions.

Regional Circular and Digital Construction Hubs

The project developed and pilot-tested regional hubs connecting businesses, research institutions, public authorities and other stakeholders. The hubs explored approaches to knowledge exchange, cooperation and support services, creating a foundation for the further uptake of circular and digital construction practices.

Common Strategy for Central Europe

Building on project findings, pilot activities and stakeholder cooperation, ReBuilt developed a Common Strategy for Circular and Digital Construction in Central Europe. The strategy brought together shared priorities and recommendations to support future cooperation, policy development and the implementation of circular and digital solutions across the construction sector.

Together, these results provided practical knowledge, tested approaches and resources intended to support the construction sector beyond the project's lifetime.

THE REBUILT LEGACY – BEYOND THE PROJECT

The completion of ReBuilt marked the transition from project development and testing to the wider application of its results.

The project's training programme and MOOC provided educational resources designed to support further professional development and knowledge transfer. Technical and digital solutions offered practical references for organisations seeking to introduce circular construction practices and improve the use of digital tools.

The regional Circular and Digital Construction Hubs and their service approach established a basis for continued cooperation between construction companies, research organisations, public authorities and innovation stakeholders.

The Common Strategy provided a shared framework for future initiatives, supporting the integration of circular economy principles and digital innovation into construction practices and regional development.
