description Material Passports (Digital) Overview

Digital material passports organize information about the materials contained in products or building components. Records can describe composition and origin, together with details useful for disassembly, reuse or recycling. Their purpose is to make information available beyond the original design and purchasing stage, when a future owner or recovery specialist may otherwise know little about what an object contains. In construction, passports support the idea of buildings as stores of materials that could be recovered later, often called urban mining.

QR codes can connect physical components to records, while some systems explore blockchain for managing information. Neither technology guarantees complete or accurate data. The approach suits projects that can maintain records over time and need to plan recovery before demolition.

help Material Passports (Digital) FAQ

How does a digital Material Passport support the circular economy?

A Material Passport creates a digital record of a product's origin, chemical makeup, and disassembly potential, preventing valuable materials from ending up in a landfill. By providing this transparency, it allows manufacturers to easily reclaim and reuse components at the end of a product's life.

Do Material Passports utilize blockchain technology?

Yes, many modern Material Passport platforms use blockchain or distributed ledger technology to create an immutable, secure record of a material's supply chain. This ensures the data regarding a component's origin and carbon footprint cannot be tampered with.

How are Material Passports accessed on physical building components?

The digital data is usually linked to the physical component via a QR code or an RFID tag affixed to the part. Scanning this code allows builders or recyclers to instantly view the "nutrition label" of the material on their smartphones.
