Knowledge Base Repository

In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
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.
