What is a primary environmental benefit of Design for Disassembly in rehabilitation devices?

• A. Increases manufacturing cost and waste
• B. Prevents recycling altogether
• C. Reduces technical compatibility
• D. Facilitates recycling and easier end-of-life repair or disassembly

Answer: (D)

Design for Disassembly aims to make rehabilitation devices easy to take apart at the end of their life, so materials and components can be recovered, repaired, or reused. In practice, this means modular components, standardized fasteners, separable materials, and clear labeling that lets you sort parts for recycling. When a device reaches end of life, disassembly is straightforward, which makes recycling more efficient and opens up opportunities for repairing or replacing individual parts rather than discarding the whole device. This reduces waste and can lower the environmental impact of disposal.

Other described outcomes would not provide environmental benefits: they imply more waste, hinder recycling, or make reuse harder, which goes against the purpose of design for disassembly.
