Product Life Cycle (4.3)
DfE is a designer’s tool box to minimize the netenvironmental impacts of a product during all stages of the product cycle.
1. Pre-manufacturing / Pre-production
2. Manufacturing / Production
3. Packaging & Transport / Distribution
4. Use
5. Refurbishment-Recycling-Disposal / Disposal
