Let’s start with the understanding that the Federal Trade
Commission states that if scrap generated in the manufacturing
process is reused for manufacturing new product, it can not be
calculated as post-industrial recycled content, as this reuse of
scrap is a part of the typical manufacturing process. So your
first question when receiving post-industrial recycled content
data should be, “How did you make this calculation, and where
did the recycled waste come from?” Stakeholder demand for
recycled content in building products has been largely driven by
the LEED® rating system, and the points gained by contributing
to the recycled content credit. Now, since scrap reused in the
manufacturing process can not be calculated, many manufactures
play a form of the “shell game”. If a manufacturer has multiple
facilities making products that generate scrap which can be
reused in all the manufacturing processes then, to calculate
post-industrial recycled content, the scrap is just moved
between facilities. Now the scrap
