Which items are considered pre-consumer recycled items?
A: Demolition debris used on another project
B: Cotton insulation manufactured from factory reject denim jeans
C: Steel beams created from metal reclaimed from the manufacturing line
D: Carpets made from nylon that include scraps reclaimed from production

参考答案: B

本题解释:
A would be considered salvaged material.


Pre-consumer content is material diverted from a waste stream during the manufacturing process. Excluded from pre-consumer content are materials that have been reutilized within the same process that generated them, such as rework, regrind, or scrap generated in the process and then put back into the process.

Cotton insulation is created from scraps from other manufacturing processes before the scraps reach consumers.

Scraps that are reclaimed and used to manufacture the same items (carpet, steel beams) do not count as pre-consumer content or post-consumer content, and thus must be excluded.
