This symbol is sometimes encountered in books and other printed matter to

and 100% recycled paper, respectively. For these purposes it is recommended
that explanatory text be placed under the symbol: i.e. it is not "pierced"
(or "combining") in the way that the corresponding symbol for plastics is.
