Industrial and Product Design Industrial and Product Design Sustainability & Environmental Design 2 — Questions and Answers
Question 1: What does 'cradle to cradle' (C2C) design mean?
- Products are designed to last from birth to old age
- All materials in a product are designed to cycle safely back into biological or technical systems (Correct answer)
- Products are made from infant-safe materials only
- Design starts over from scratch with each generation
Correct answer: All materials in a product are designed to cycle safely back into biological or technical systems
C2C design ensures all materials are nutrients for either biological cycles (composting) or technical cycles (industrial reuse), eliminating the concept of waste.
Question 2: Which factor is most important when selecting a material for a sustainable product design?
- Lowest unit cost alone
- Full lifecycle impact including extraction, processing, use, and end-of-life (Correct answer)
- Highest tensile strength
- Most vibrant color range available
Correct answer: Full lifecycle impact including extraction, processing, use, and end-of-life
Sustainable material selection requires evaluating environmental impacts across the full lifecycle, not just upfront cost or mechanical properties.
Question 3: What is 'embodied energy' in the context of sustainable product design?
- The energy a product generates during use
- The total energy consumed to extract, process, manufacture, and deliver a product (Correct answer)
- The energy stored in a battery-powered product
- The kinetic energy of moving product parts
Correct answer: The total energy consumed to extract, process, manufacture, and deliver a product
Embodied energy accounts for all energy inputs required to bring a product into existence, from raw material extraction through manufacturing and delivery.
Question 4: Which of the following best describes 'upcycling' in product design?
- Recycling a product into lower-quality material
- Transforming waste or discarded materials into products of higher value or quality (Correct answer)
- Upgrading software on a smart device
- Selling used products at higher prices
Correct answer: Transforming waste or discarded materials into products of higher value or quality
Upcycling creatively repurposes waste materials into products of greater value, unlike downcycling which produces lower-quality materials.
Question 5: What is a 'product stewardship' program in the US?
- A design award for innovative products
- A system where manufacturers take responsibility for end-of-life management of their products (Correct answer)
- A supply chain auditing process
- A government-run product testing lab
Correct answer: A system where manufacturers take responsibility for end-of-life management of their products
Product stewardship programs hold manufacturers responsible for collecting and properly recycling or disposing of their products at end of life, such as electronics take-back programs.
Question 6: Which sustainable design strategy focuses on extending product life through repair, refurbishment, and upgradability?
- Planned obsolescence
- Design for longevity (Correct answer)
- Fast fashion design
- Throwaway design
Correct answer: Design for longevity
Design for longevity deliberately creates products that last longer through repairable components, modular upgrades, and durable materials, reducing overall resource consumption.
