The concept of material passports can provide a document for each material which can hold all the important related to it that you need throughout its life
Currently, demolition and new build is cheaper than deconstruction and refurbishment. Due to the unknowns of what might be found at an existing building and how long this might impact the programme, many clients prefer to demolish and build anew. Similarly with regards to materials, it is cheaper to buy new materials than to salvage and utilise reused ones. The uncertainty of this process, the re-certification of the materials, the fact that this procedure is still new and unfamiliar, makes it “unsustainable for a single client to bear the cost” (Elliot Wood, ‘Full Circle to Reuse’). To lower carbon emissions of a
project, one must be aware of what routes are available to addressing carbon reduction in buildings, and understand the impacts of each route. Similarly, understanding circularity and how its principles work is key. There is a vast array

of organisations which identify the principles of circularity differently – and there are some misalignments. It’s important to understand what they are and how they work together, since circular economy is a holistic way of thinking about waste prevention, recirculation of materials and regenerating systems. Clearly establishing the value that circularity would bring to a project and the purpose of the principles applied would also assist in their successful implementation.
The identification of buildings (both existing and new build) as material banks or material stores, ready to be mined at the end of their life, is a concept widely researched by the BAMB 2020 Horizon programme. Successful reuse of a material and its deconstruction relies to a large extent on the information available for this material and its existence and upkeep. The concept of
‘material passports’ is an example of how this could be done – a document for each material which holds all the important information related to that material, which you need throughout the various stages of its life, including deconstruction or reuse. While several years ago this concept was largely conceptual, working platforms already exist and are used in pilot schemes both in the European Union and within the United Kingdom.
The gathering and storage of this information could also mean changing the way consultants such as architects and engineers produce their working information and building models. 3D modelling software is becoming increasingly more capable of storing such large amounts of information and extracting it via different platform plug-ins for various tasks, i.e. to populate bills of quantities.
