What is design for disassembly?

• A. Increases production cost
• B. Makes disassembly harder
• C. Enables easy repair, upgrades, refurbishment, end-of-life recycling
• D. Reduces product lifespan

Answer: (C)

Design for disassembly focuses on making products easy to take apart at the end of their life so components can be repaired, upgraded, refurbished, or recycled. The idea is to design with the product’s end of life in mind: modular parts that fit together with reversible joining methods, standardized fasteners, and materials that can be separated without damage. This often means using screws instead of glue, providing clear access to components, labeling materials, and avoiding permanent bonds between different materials.

When a product is easy to disassemble, repairs and upgrades become practical, extending the product’s useful life. It also makes recycling more efficient because materials and components can be recovered and reused rather than mixed or wasted. Overall, design for disassembly supports a circular economy by reducing waste and keeping valuable materials in use longer.

That’s why the option describing easy repair, upgrades, refurbishment, and end-of-life recycling best captures the purpose of design for disassembly. It’s not about increasing production costs, hindering disassembly, or shortening the product’s lifespan.
