The design for recycling of electronics guide: from recycling practice to design method Delft University of Technology, The Netherlands Electronic waste is one of the fastest-growing waste streams, yet only a small fraction is properly recycled. Many challenges in recycling originate in product design; for example the choice of materials and joining methods. This paper presents the first version of the Design for Recycling of Electronics Guide, developed to bridge the gap between design and recycling practice. Based on case studies, shredding experiments, and method reviews, it provides practical guidance to help designers anticipate and improve recyclability during product development. Set-based design approach for renewable energy integration in social housing: design space mapping with a morphological chart 1Université de Bordeaux, ESTIA-Institute of Technology, EstiaR, France; 2Comité Ouvrier du Logement (COL), France The EU 2050 carbon neutrality target drives growing interest in renewable energy (RE) integration in building design, yet social housing organizations face difficulties integrating them early in design due to complexity and high upfront costs. This paper presents a three-step method based on the Set Based Design approach to define the design space using a morphological chart. This offers a robust and adaptable framework to formalize and structure domain-specific knowledge, clarifies design options, and supports informed decision-making for RE integration in social housing design. Bayesian optimal experimental design for circular business models The University of Tokyo, Japan Implementing circular business models (CBMs) like Product-as-a-Service entails high uncertainty, necessitating costly and prolonged business experimentation. To efficiently mitigate this uncertainty, Bayesian Optimal Experimental Design is applied to the CBM context, selecting conditions that maximize the Expected Information Gain for unknown CBM parameters. Applied to an air conditioner subscription case study, the method successfully identified optimal conditions from 124 candidates. This approach facilitates CBM implementation by efficiently minimizing uncertainty under limited resources. Towards a methodical framework for the design of functional surfaces in circular automotive engineering 1Institute for Engineering Design, Technische Universität Braunschweig, Germany; 2Institute for Surface Technology, Technische Universität Braunschweig, Germany This paper proposes a methodical framework for developing functional surfaces and coatings for circular automotive applications. It addresses three gaps: the missing classification of surface mechanisms, limited empirical PSPP models, and the lack of an integrated link between microstructural surface design and system-level development. The framework connects top-down design with bottom-up materials engineering, introduces working-principle analogues in design catalogues, and offers the use of DoE and sensitivity analysis to build predictive PSPP models. | ||
