TraceabilityTraceability in aluminium scrapAluminium scrap recyclingRecycling is still in its early stages of development, but it is critical for enhancing scrapScrap value and supporting the transition towards circular materials. This study explores the potential barriers and enablers to improving traceabilityTraceability in aluminium scrapAluminium scrap recyclingRecycling and secondary production supply chains. Based on broad insights from the literature, including the lessons from plastics and construction, it synthesises existing challenges and enablers. Common barriers include limited data availability, poor system integration, and high costs of implementing new systems. Enabling factors include emerging digital solutions, such as blockchain and Digital Product Passports, as well as advanced marking and material identification technologies. Building on this synthesis and an information flowInformation flow analysis, this study proposes a framework of traceabilityTraceability improvement entry points. The proposed framework offers guidance for researchers on advancing traceabilityTraceability and information flowInformation flow research within open-loop recyclingRecycling systems. It also provides a practical vision for recyclers to develop new business models that enhance information flowInformation flow, particularly by leveraging emerging digital solutions. By addressing existing information gaps and strengthening traceabilityTraceability, these strategies can improve recyclingRecycling efficiency and enable informed, data-driven decision-making across the aluminium recyclingAluminium recycling value chain.
