The recent study, published in Science of the Total Environment, explores how circular economy principles can be effectively applied to innovative bio-based materials across three value chains: multifunctional rubber panels, bioplastic bottle closures, and wood composite bearings. Using a comprehensive methodological approach that combines Material Flow Analysis (MFA), circularity indicators, and Bill of Materials (BoM), the research identifies both the potential and limitations of resource recovery, waste reduction, and closed-loop system design.
The results highlight significant circularity potential for these products. However, barriers persist, including challenges in recovering chemical inputs during lignin extraction, regulatory constraints on bioplastics, and technical limitations in disassembling wood components. Despite this, the study outlines actionable strategies: enhancing eco-design, scaling up recycling technologies, and improving component traceability.
This work not only supports Circular Economy goals but also provides a practical toolkit for companies and policymakers to measure and improve the circularity of bio-based production systems. The study underscores the critical role of BoM and MFA in quantifying sustainability performance, advancing innovation, and guiding decision-making in the circular bioeconomy.
