Question
Name Datchefski's five principles.
Answer
Cyclic (creates no waste), solar (uses clean energy), safe (causes no harm), efficient (least material and energy), social (supports basic human rights).
Question
What does the cyclic principle require?
Answer
That every part can return to a cycle — made from recycled or renewable material and recyclable or compostable at the end. A laminate or a glued joint usually breaks it.
Question
Why is efficiency measured per year of service?
Answer
Mass and energy only mean something against the service delivered. A chair 40% lighter that lasts half as long uses more material per year of use.
Question
Where does the social principle usually fail?
Answer
Below tier one of the supply chain: final assembly is visible and audited, while the fabric, fixings and raw materials are two or three tiers away and rarely traced.
