A shift towards Circular Economy (CE) necessitates long-term documentation and dissemination of information for reusing materials and products in the existing built environment. Serving this purpose, Material Passports (MPs) encompass the composition and specifications of materials used in building components throughout their lifecycle, facilitating reuse, recycling, or remanufacturing of materials in future construction projects. However, the processes for compiling MPs remain unstandardized, lacking consensus among stakeholders and governing bodies. This work outlines a standard procedure for MP compilation by reviewing previous literature and current practices. To this aim, Systematic Literature Review (SLR) is employed to explore the state of the art of the research related to MPs for CE assessments. Using text-based coding in NVIVO, Critical Success Factors (CSFs) of MP compilation and their interrelationships are extracted. To work out the significance of the CSFs and their interrelationships, the article categorizes CSFs into operational, foundational requirements and data management factors, and illustrates the interrelationships in terms of explicit, implicit and managerial dependencies. Based on these insights, the study proposes guidelines for developing comprehensive MPs. The proposed MP protocol introduces a standardized approach for digital integration, stakeholder engagement, and policy adoption to enhance MP implementation in the building industry.

Abstract
A shift towards Circular Economy (CE) necessitates long-term documentation and dissemination of information for reusing materials and products in the existing built environment. Serving this purpose, Material Passports (MPs) encompass the composition and specifications of materials used in building components throughout their lifecycle, facilitating reuse, recycling, or remanufacturing of materials in future construction projects. However, the processes for compiling MPs remain unstandardized, lacking consensus among stakeholders and governing bodies. This work outlines a standard procedure for MP compilation by reviewing previous literature and current practices. To this aim, Systematic Literature Review (SLR) is employed to explore the state of the art of the research related to MPs for CE assessments. Using text-based coding in NVIVO, Critical Success Factors (CSFs) of MP compilation and their interrelationships are extracted. To work out the significance of the CSFs and their interrelationships, the article categorizes CSFs into operational, foundational requirements and data management factors, and illustrates the interrelationships in terms of explicit, implicit and managerial dependencies. Based on these insights, the study proposes guidelines for developing comprehensive MPs. The proposed MP protocol introduces a standardized approach for digital integration, stakeholder engagement, and policy adoption to enhance MP implementation in the building industry.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
