D341: METHODS AND TOOLS FOR PRODUCT CIRCULARITY ASSESSMENT

    | ||
Holistic product circularity assessment of a balance bike Saarland University, Germany This paper operationalizes ISO 59020 for product-level circularity by implementing the Holistic Product Circularity Analysis (HPCA) with fixed boundaries and explicit reporting rules. HPCA enables consistent assessment and targeted optimization by combining qualitative ratings with quantitative flows across all stages of the product lifecycle. The approach is demonstrated on a children’s balance bike by comparing a reference scenario with an optimized circular scenario and deriving decision-relevant improvement levers. Circular Life Cycle Blueprint: a visual tool for circular product and component design Singapore University of Technology and Design, Singapore The Circular Life Cycle Blueprint (CLB) is a four-step design methodology for integrating circular economy principles at the component level in product design. Developed via a design science approach with iterative prototyping and evaluation, the CLB guides design teams from conceptualizing circular strategies to mapping component lifecycles and conducting a sustainability assessment. Pilot evaluation with industry professionals indicates that the CLB is effective and user-friendly, fostering innovative circular design and demonstrating practical viability in sustainable product development. Hierarchical lifecycle modelling in circular product development 1Institute of Human Factors and Technology Management (IAT), University of Stuttgart, Germany; 2Fraunhofer Institute for Industrial Engineering IAO, Germany As companies face increasing accountability for resource efficiency, circularity measures like repair or remanufacture offer a promising solution. Modeling expected product lifecycles in early design phases is crucial for planning their effective application. This paper introduces a hierarchical lifecycle model to represent component-specific lifecycle paths across all product architecture levels in a single model. Our approach ensures consistency across hierarchy levels and facilitates precise application of component-specific circularity measures, promoting effective circular product design. Analyzing product circularity: a comparative assessment of existing approaches and development of a retention-option-weighted multi-criteria assessment tool 1Saarland University of Applied Sciences, Germany; 2ECO² Research Group, Fraunhofer IZFP, Germany The circular economy is central to sustainability, yet many products cannot comply to its principles. Equally, assessing circularity remains challenging due to the multitude and complexity of approaches. This contribution presents a feasible multi-criteria assessment tool, grounded in established DfCE principles, for evaluating product circularity at various system levels. Developed through an exploratory literature review, it integrates qualitative and quantitative indicators with a retention-option-based weighting system. Its applicability is demonstrated through a medium-complex case study. | ||
