The materials passport is a unique digital document that gathers detailed information on each material used in a project, including its description, quality certifications, technical specifications, and geographical origin. This tool makes it possible to calculate the carbon footprint and optimize resource management throughout the entire life cycle of the product.
The pilot was carried out at the prefabricated bathroom factory in Jumilla (Murcia), in collaboration with the startup Cuatro Digital and suppliers such as Pladur and Canteras y Hormigones. The primary aim was to establish a blockchain-based methodology to guarantee the traceability of materials used in modular bathroom production.
“This system collects key information on every material, allowing us to measure its environmental impact and generate precise traceability reports,” explains Patricia Díaz, Innovation Business Partner with Sacyr Engineering and Infrastructure.
The bathrooms produced with this methodology were supplied to the NODE housing development in Carabanchel (Madrid). Thanks to this solution, it has been possible to:
- Connect the different stakeholders across the value chain during the industrialized construction process.
- Ensure efficient management of resources.
- Advance toward more sustainable operations through a secure platform that provides insights into material lifespan and reuse potential.
Recognized by Madrid City Council
The development of this pilot was made possible thanks to an award from Madrid City Council, granted in the first edition of the “Blockchain and Advanced Technologies Projects” competition. In this call, Cuatro Digital, presented by Sacyr, was selected as the winner.
These awards seek to recognize and support startups and professionals that stand out for proposing innovative solutions based on disruptive technologies.
Next steps: scaling up and regulatory alignment
Following the success of the pilot, we are now focused on scaling the model to other projects and construction processes. This work aligns with the European regulatory framework, which in the coming years will require detailed information on the materials used in all buildings within the European Union.
“We are working to scale up this solution and get ahead of upcoming European regulatory requirements,” concludes Patricia Díaz.
