Reused, as in old paper fibres made into new paper. The recycled content is the percentage of reused fibres. 100% recycled 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 fibres.
A term used to describe material that has been separated from the waste stream, reprocessed into a new product (often taking the place of virgin material), and then bought back by the consumer as new item.
Recycled papers contain a post-consumer fibre, which meets the recycled content standards of the federal, state, and municipal governments.
