Recycled Paperboard: for purists only?

Created in 1995 by the 100% Recycled Paperboard Alliance, Inc. (RPA-100%), the 100% recycled paperboard symbol is displayed today on a wide range of products and packaging made with 100% recycled paperboard.

So this symbol is for recycled material – to show off the manufacturers’ green credentials -, but doesn’t mean that the material is recyclable again.
