ABN AMRO signed an agreement with MADASTER on Wednesday, 31 May during the PROVADA real estate exhibition in Amsterdam. The MADASTER materials passport is set to become the new standard in the real estate sector. Generating a digital materials passport for every building opens up the possibility of creating a circular economy within the construction industry. ABN AMRO is contributing both financially and substantively to the development of this independent method of creating transparency in the use of materials and raw materials in construction projects. The passport can be initiated by clients and used by architects and contractors in new-build and renovation projects. This makes MADASTER an independent public platform for private individuals, businesses and public authorities.

The MADASTER materials passport is a digital document that records the identity of all construction materials used, documenting the products and raw materials used in a building or project. The circular value of these materials depends among other things on how they are incorporated into the building. The agreement was signed by Egens Holleman, Corporate Real Estate Manager at ABN AMRO, and the initiator of the concept, Thomas Rau from MADASTER.

‘Land registry’ for construction materials

A materials passport for a building provides a digital record of the materials used in the construction, and in what quantities and dimensions. It also contains information about the quality of the materials and their location. This makes reusing and reclaiming materials during demolition or disassembly much simpler. It also has benefits for the owner, who retains the raw materials and second-hand products, all of which have a value. A building that is ready for demolition thus becomes a ‘storehouse’ of useful materials. 

“MADASTER is like a ‘land registry’ for materials’, says Thomas Rau. ‘Raw materials aren’t scarce, but they are limited. It’s therefore important that we document them accurately, so that they remain available indefinitely. The materials passport gives materials an identity, which means they can never again simply disappear anonymously as waste. MADASTER generates the materials passports, but also acts as a library. We are really pleased that ABN AMRO is supporting this public platform’.

The idea also inspired ABN AMRO to get together with CAD&Company, the circular economy specialist Rendemint and the architects’ firm Architekten Cie to develop its own materials passport for the circular ABN AMRO pavilion CIRCL which will open its doors in September 2017.
