Materials passports


The mission of BAMB is to enable the shift to a circular building sector. Effective recovery and reuse of components, products or materials in buildings requires that the right information is easily accessible. This information is also crucial for choosing materials, products and components that later can be re-used.

Materials Passports

The electronic Materials Passports developed in BAMB aim to be a one stop shop for material information. Materials Passports developed in BAMB are sets of data describing defined characteristics of materials in products that give them value for recovery and reuse.

BAMB Materials Passports aim to:

  • Increase the value or keep the value of materials, products and components over time
  • Create incentives for suppliers to produce healthy, sustainable and circular materials/building products
  • Support materials choices in Reversible Building Design projects
  • Make it easier for developers, managers and renovators to choose healthy, sustainable and circular building materials
  • Facilitate reversed logistics and take back of products, materials and components

Within the project more than 300 Materials Passports for various products, components or materials are developed together with a software solution. The software will facilitate the appropriate accessibility of information for different stakeholders at specific stages in the process.

There are already some materials passports and other ways to collect information about materials and building products, e.g. material databases, but none have the full ability to support a circular use of sustainable materials.

Material Passports provide the necessary information about materials, products and components for a circular use of building materials, products and components whilst supporting reversible design.

Read the report “Deliverable 7 Operational Materials Passports” (pdf 1,7 MB) This report describes how BAMB have achieved and succeeded the goal of generating 300 MP as part of our work in BAMB. It also provides information on the continued efforts on MP and our current focus on standardisation and harmonisation.


Materials Passports Platform Prototype

The BAMB Materials Passports platform will fill a gap in the marketplace by providing a ‘one-stop-shop’ to describe Circular Economy value across the building cycle, especially for using and re-using components and materials, and reducing generation of waste.

A main aim is to support transition of the building industry from linear to circular by letting users identify value potential throughout the building cycle, from planning and construction through occupancy, repairs, renovations, repurposing and decommissioning, and by providing a continuous capacity to track component and materials quality & modifications.

The platform also connects individual products to their use in buildings. As part of that it includes a capacity to describe materials health. A large body of studies suggests that healthier buildings improve productivity and are one of the main economic benefits of knowing what’s in your building.

Standardization and existing tools

There are several existing standards and tools with thematic relations to Materials Passports. Passports have the potential to incorporate existing standards and tools and to incorporate others which are generally not answered by the existing mechanisms. Materials Passports developed in BAMB have the potential to incorporate existing mechanisms such as TDS, MSDS, EPD, Bill of Materials, Bill of Substances, etc where relevant as support for circularity claims.


This avoids reproducing data and reinventing the wheel, which are key concerns of product manufacturers and their suppliers, who will play an important part in populating passports.

Transparency and secrecy

Two topics of high importance for the development of Materials Passports are those of transparency and secrecy. Information stored for Materials Passports should have a purpose. That means that is should be accessible by those parties capable of connecting it to an action. Having information stored which cannot be accessed due to secrecy is not beneficial for this.
