DCaS-R. Circular Data as a Service for Construction Waste

Duration

Start date: 01/09/25

End date: 28/02/26

Total budget: 184.770,00 €

Grant received: 10.000 €

Grant call: Grants for projects on transfer and innovation, knowledge generation, startup communities, ethics and society, and data spaces in the field of AI (RETECH) – Next Generation EU.

The DCaS-R project develops a federated data space for the circular traceability of materials and waste in the construction sector.

The initiative promotes the digitalization and sustainability of the sector through the creation of a Digital Waste Passport (DWP), aligned with European standards EPCIS 2.0, GS1 and IFC. This infrastructure enables the secure and standardized exchange of real data from construction sites, waste managers and recovery operators, integrating automatic sustainability indicators such as carbon footprint, life cycle analysis, and material recovery.

We have developed a federated data space that promotes the circular traceability of materials and waste in construction through a Digital Waste Passport aligned with European standards. Through Blockchain technology, semantic ontologies, EDC connectors and an interoperable data infrastructure based on European standards such as EPCIS 2.0, GS1 and IFC, all integrated within an i2CAT sandbox environment.

Participants

Specific Objectives

Share real information on materials and waste through EDC (Eclipse Data Connector) connectors and a common sectoral ontology, ensuring data consistency and quality across the entire ecosystem.
Develop and validate the Digital Waste Passport (DWP), a tool that digitizes material traceability, automates environmental indicators such as carbon footprint and life cycle analysis, and supports sustainable decision-making.
Promote the digital and circular transformation of the sector by fostering transparency, collaboration and efficiency in construction processes, and establishing the foundations for a European model of environmental data exchange applicable to other industrial sectors.
