Answer:
This approach is a technique used to appraise the environmental impact associated with all stages of a product's life. (from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal-recycling).
Step-by-step explanation:
Everything that is produced goes through these five main stages:
1.) material extraction
2.) manufacturing
3.) packaging
4.) transportation
5.) use and end of life
At each of these stages, there are inputs and outputs, flow-throughs, value losses, and potential gains.
