Reference: LEED for Existing Buildings: Operations & Maintenance Reference Guide, Glossary

A:Pallets are post-consumer waste since the shipping company did not manufacture them (they used them, they did not make them).
B:Pre-consumer content is content from industry scraps that was diverted from the waste stream and used for other purposes. Examples include sawdust, wood shavings, wood chips, and print overruns. Excluded are materials that are re-incorporated into the same manufacturing process that generated it.
Print overruns are considered pre-consumer recycled content.
C:Excavated soil doesn\'t count as a recycled material.
D:This is post-consumer recycled content, assuming the drywall gets recycled.
