European Architecture, Engineering and Construction industry (AEC) consumes a significant rate of materials like steel, aluminum, copper and plastics, thus creating a large reservoir on secondary raw materials in buildings. One of the main strategies of the European Union is to maximize recycling rates in order to minimize environmental impacts and the energy consumption caused by extraction of primary materials. To enable circularity, and in consequence high recycling rates, information about the existing stock is necessary.
The early design stages play a crucial role in the waste reduction, the reusability of the building elements as well as in the increase of the recycling potential. As planners and architects are major decision makers regarding the design, materials, construction and assembly method, they bear large responsibility defining the resources efficiency over the life cycle. In order to optimize the recycling potential and material composition of buildings, new design-centric tools and methods are required as well as tools, which enable a compilation of data repositories on the material composition
of buildings.
The potential of an automated generation and data management for a Material Passport (MP) was tested through linking BIM to the Material Inventory and Analysis Tool, thus allowing the assessment of embedded materials in buildings. Further on,the MP acts as a crucial instrument for material manufacturers, construction companies, engineers and architects, recycling and waste companies and policymakers. Thereby the successful implementation of the MP in the AEC industry requires close collaboration of a broad spectrum of stakeholders, in order to achieve standardization and regulatory frameworks.
The results show that the semi-automated compilation of a MP is possible, even though there exist several obstacles. In this work, we also show the role of the stakeholders in generating a MP through a data and stakeholder framework.
