Re: [GreenYes] Papermaking

Does anyone know how much calcium carbonate is used in making recycled paper?  If the argument is truly mineral-vs-trees, then using more recycled fiber ought to reduce the number of trees required, thereby changing the calculation substantially.  Or is the issue "bright" paper?  I'm sure there are products for which calcium carbonate is the best available raw material (possibly the other uses mentioned in the WSJ article).  But if its being used instead of recycled paper fiber and only to produce blindingly white paper, then (IMHO) the argument for mining doesn't hold water (so to speak).
