D311: CONCEPTS, FRAMEWORKS AND PRACTICES IN CIRCULAR DESIGN

Analysis of product life cycles in the context of the circular economy and its strategies University of Stuttgart, Germany The product life cycle (PLC) is the basis for every development task. Its modeling is especially important in the context of the circular economy, as recirculation within the PLC forms its basic concept. To derive requirements for circular products, it must be known which phases are to be passed through within which circular strategy. This paper links R-strategies and life cycle phases by analyzing 56 life cycle models in regard to the number of phases, sequence, and other characteristics. A dependency matrix consolidated from the life cycles allows the findings to be utilized further. Circular design meets environmental sensing: a comparative study University of Strathclyde, United Kingdom This design-led study explores how circular economy principles can be embedded in research prototyping while comparing environmental sensing methods. A reusable outdoor prototype, deployed in three contexts, combined embedded sensors and API data. Using proxy indicators (energy, material mass, emissions) and end-of-life planning, API sensing indicated a far lower impact, while embedded sensing offered hyper-local data. All prototype components were either reused or repurposed, demonstrating circular prototyping in practice, with findings intended as design-informing rather than definitive. Towards collaboration in circular ecosystems: barriers, enablers, and insights from European projects 1Division of Product Development, Department of Industrial and Materials Science, Chalmers University of Technology, Sweden; 2Department of Design, Politecnico di Milano, Italy This study examines barriers for circular ecosystems in literature, and identifies 11 enabling factors for collaboration in circular ecosystems. Based on a web-based analysis of 763 European CE projects, the study analyses how factors are addressed in practice. Collaborative processes, trust building, and technological enablers were most frequent, supporting relational foundations via digital tools. Projects often signal collaboration but rarely detail governance or ecosystem orchestration. Findings highlight design capabilities to foster shared-value creation in circular ecosystems. A systematic review on the implementation of Cradle to Cradle in product development 1Leuphana University Lüneburg, Germany; 2Siemens Healthineers AG, Germany Cradle to Cradle (C2C), as an eco-effective approach to the circular economy, helps mitigate the environmental impacts of the linear economy; however, its implementation in product development remains challenging. Due to limited prior reviews, this research investigates the implementation of C2C in product development. Through a systematic literature analysis, we identify key topics and challenges and examine how eco-efficiency and eco-effectiveness are addressed. Based on these findings, future research should develop a framework for implementing eco-effectiveness in product development. | ||
