Holistic product circularity assessment of a balance bike
Dominik Neumann, Simon Moersdorf, Michael VielhaberABSTRACT:
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.
