Design for recycling is a design discipline that aims to enable the efficient recovery and reuse of materials from products at end of life. It seeks to minimize the use of materials that are not easily recyclable, simplify the disassembly process, and reduce contamination of recycling streams, thereby supporting the principles of a circular economy.

Practices include selecting widely recyclable materials, avoiding multilayer or mixed-material constructions, and designing for disassembly with standardized fasteners and modular components. Designers may use compatible materials and avoid difficult coatings or adhesives that hinder separation. Clear labeling and documentation for recyclers, as well as consideration of the local recycling infrastructure, are also important aspects of the approach.

The design-for-recycling process intersects with product life cycle assessment and end-of-life management. Products may undergo mechanical recycling for plastics and metals or, in some cases, chemical recycling for certain polymers. The goal is to maximize recoverable material value, minimize hazardous substances, and ensure compatibility with existing recycling streams.

Challenges include trade-offs with durability, performance, and cost, as well as variability in recycling capabilities across regions. Realizing high recyclability often requires standardization, take-back programs, and policy incentives, such as design-for-recycling guidelines and recyclability labeling.

Applications span packaging, consumer electronics, automotive components, and household appliances. Key metrics include recyclability rate, disassembly time, material compatibility with recycling streams, and the ease of separating constituent parts. Design for recycling is most effective when integrated early in product development and aligned with broader circular economy strategies.
