Material Passports for the End-of-Life Stage of Buildings: Challenges and Potentials

Global consumption of non-renewable resources is increasing and shortages of primary raw materials and reduction of space for final waste disposal are raising urgent issues for our communities.  The unsustainable use of resources is resulting in strategies for maximizing recycling rates and minimizing environmental impacts and energy consumption due to the extraction of primary materials.  A material passport (MP) at a building’s end of life (EOL) supports construction sustainability and circularity and encourages the recycling and reuse of building materials, rather than their disposal as waste.  This paper illustrates the workflow compilation process and use of an EOL material passport.
