Design for disassembly in footwear: identification and classification of product requirements

This work investigates the development of sneakers designed under Design for Disassembly principles and supported by additive manufacturing to promote a more sustainable and circular product life cycle. By responding to the limitations of traditional footwear assembly, the study identifies and organises 35 technical requirements derived from consumer needs. The proposed model offers a clear and adaptable framework that enhances decision-making in early design stages, guiding the creation of innovative, recyclable and environmentally responsible footwear solutions.
