Material Passports for Circularity Indicators: a Compatibility Metric

Abstract: Material Passports (MPs) can play a crucial role in advancing Circular Economy (CE) principles, thanks to their features of documenting and tracking material properties throughout lifecycle. This study explores the potential of MPs as a valuable source of information for circularity assessments. A systematic review identifies key quantitative circularity indicators and their data requirements, which are compared with MP data availability. The resulting compatibility metric highlights MPs’ capability to provide essential material parameters for CE assessments. The findings prove the potential of MPs to support and simplify circularity assessments for enhanced effectiveness and greater accessibility.
