Reused, as in old paper fibers made into new paper. The recycled content is the percentage of reused fibers. 100% reccycled means it was all reused at one point. However, this could mean that the paper manufacturer had simply thrown mill waste (Pre-Consumer content) back into the vat. The real indicator is Post-Consumer content, which tells you what percentage of the recycled content was paper diverted
from the waste stream and reused instead of buried in a landfill. Paper with 100% post-consumer content is sometimes called "tree-free" because no trees had to be used to produce the paper; however, tree-free could also refer to paper produced from kenaf, hemp or other
non-wood fibers.
