What is the concept of design for disassembly?

• A. Selecting materials and connections that allow easy reuse or recycling at end of life
• B. Permanent fastening and sealed joints
• C. Maximizing weight and complexity
• D. Reducing material reuse to minimize costs

Answer: (A)

Design for disassembly means planning a product so it can be easily taken apart at the end of its life, so its components can be reused, refurbished, or recycled. This involves choosing materials and connections that are straightforward to separate and sort for recycling, such as detachable fasteners, modular assemblies, and joints that don’t rely on permanent adhesives or complex bonding. Designing with disassembly in mind helps reduce waste and makes recovery of valuable materials or components more feasible, which can lower environmental impact and preserve resources. Permanent fastening and sealed joints lock components together and are hard to separate; excessive weight and unnecessary complexity make disassembly more difficult; and reducing opportunities to reuse materials goes against effective end-of-life handling, increasing waste and costs.
