▶What's circular economy and how is it different from sustainability?
Sustainability = minimize harm (reduce carbon, recycle). Circular economy = positive design (products biodegradable or infinitely recyclable). Example: plastic bag = sustainable if carbon-neutral, circular if compostable in 6 months. Circular is harder (requires redesign) but better (zero waste ideal).
▶Can fast fashion brands adopt circular economy?
Partially. True circular = fiber-to-fiber recycling (hard for mixed fabrics), or biological decomposition (100% natural fiber). Reality: take-back programs (Patagonia, Everlane) = partial circular. Fully circular fast fashion = oxymoron (fashion is trend-driven; durability contradicts trend). Possible: slow fashion / luxury (designed to last decades).
▶What's Design for Disassembly (DfD) and why does it matter?
DfD = product designed to be taken apart (easy material separation, no adhesives). Example: modular phone (Framework) = easy to replace battery/screen. Benefit: repair extends life, materials recover value. Cost: slightly higher upfront (DfD adds $5-50 depending on complexity). Return: lower landfill, customer loyalty.
▶How do I measure if my product is truly circular?
Life Cycle Assessment (LCA) = scientific method (ISO 14040). Tools: SimaPro, GaBi. Assess: raw material extraction, manufacturing, use, end-of-life. Circular score = percentage of materials recovered/recycled. Bonus: Cradle-to-Cradle certification (3rd-party validation). Without LCA, you're guessing.
▶What's the business case for circular design?
Costs: (1) R&D (2-3 years, $2-10M depending on product), (2) supply chain restructuring. Benefits: (1) EU regulations forcing it (fines $10M+), (2) brand premium (consumers pay 10-20% more), (3) material cost savings (recycled often <virgin), (4) longevity = new revenue model (repair subscriptions).
▶How does a circular economy business model work?
Traditional: sell product once, done. Circular: (1) lease/subscription (user pays per month, you keep ownership, incentivizes durability), (2) take-back program (collect used, refurbish, resell), (3) material recovery (process end-of-life for virgin material). Example: car-as-a-service = Zipcar model.
▶What salary for circular economy expertise?
Sustainability manager ($80-110k) + circular design = $110-150k. Product manager ($110-150k) + circular focus = $150-200k. Growing 15%/year, especially in: Nordics (Patagonia, IKEA), UK (post-Brexit environmental focus), EU (regulations). Future-proof skill.
