Abstract

Sustainable and circular product design has emerged as a critical approach to mitigating environmental impacts, promoting resource efficiency, and extending the lifecycle of products. This review examines the principles, methodologies, and challenges associated with sustainable and circular design, with an emphasis on material selection, life cycle assessment, and product end-of-life strategies. Key frameworks such as the Cradle-to-Cradle (C2C) model, Life Cycle Thinking (LCT), and Design for Disassembly (DfD) are discussed. The paper also explores industry case studies and technological enablers, including digital twin simulation and additive manufacturing, which support circularity. The review concludes by highlighting future research directions to integrate sustainability deeply into mainstream product development processes.

Keywords: Circular Economy, Sustainable Design, Life Cycle Assessment, Cradle-to-Cradle, Design for Disassembly, Resource Efficiency.
