CALAF Constructora is part of the DCaS-R – Circular Data as a Service for Waste project, a pioneering initiative that has launched a federated data space to improve the traceability and circular management of materials and waste in the construction sector. The project, funded by the European Union through Next Generation EU and with the support of the Government of Catalonia, aims to prepare the sector for new regulatory demands and accelerate the transition towards more sustainable and digital models.

The data space being developed allows information to be shared in a standardized, interoperable, and secure manner among constructors, waste managers, transporters, valorizers, and administrations. At its core is the Digital Waste Passport, a tool that digitizes the traceability of materials generated on-site and automates environmental indicators, such as carbon footprint or water footprint, thus facilitating data-driven decision-making.

In the DCaS-R pilot, real data from construction sites, transport processes, and treatment plants is being integrated, validating a common data model, a shared governance system, and connectors that allow information exchange among stakeholders with different levels of digitalization. This framework will enable the generation of reliable evidence that will be useful for certifications, audits, and compliance with regulations evolving towards the traceability and verifiability of construction products and materials.

The project consortium is coordinated by Blue Room Innovation, which leads the technical design of the data space, the digital architecture, and the development of the Digital Waste Passport. In addition to CALAF Constructora, partners include inèdit (with the development of the environmental quantification system), CELSA Group, and FERIMET, which contribute expertise in waste classification and valorization. The Catalonia Waste Cluster (CREC) – in collaboration with the Catalonia Waste Agency (ARC) – validates the governance model and ensures the project’s alignment with sector needs.

Through this collaboration, CALAF Constructora reinforces its commitment to innovation, digitalization, and the circular economy, actively contributing to promoting more efficient and sustainable practices in construction and waste management.
