Question
Name the five cradle-to-grave stages.
Answer
Raw material extraction, manufacture, distribution and transport, use and maintenance, and disposal and recycling.
Question
Which stage dominates, and how do you tell?
Answer
For a powered product, use. For a passive one, extraction. Ask whether the product consumes anything while it works.
Question
What is the difference between cradle to grave and cradle to cradle?
Answer
Cradle to grave ends at disposal. Cradle to cradle recovers the material so it re-enters the first stage of the next product.
Question
Why is a longer life usually the largest saving?
Answer
Doubling a working life halves the impact of everything that made it, per year of service — which almost no material substitution can match.
