Designing for Disassembly and Reuse: A Modular Repair Model Proposed in the Manual of Good Practices for the Production and Recycling of Waste from Electrical and Electronic Equipment

This paper proposes a modular design approach based on Design for Circular Disassembly (DfCD) to reduce waste and repair costs in Electrical and Electronic Equipment (EEE). Drawing from practical examples and aligned with European circular economic directives, the study demonstrates how product architecture and repair protocols can be restructured to enable component-level maintenance and reuse. The methodology includes design criteria, a conceptual case study, and an implementation roadmap. The results suggest that DfCD improves sustainability, extends product lifespan, and supports circular business models.
