Here's one that was staring me in the desk the whole time ...

I'm not sure of the monetary savings (specifically) involved in this one but it is good for the pocket book and the earth.

At work or at home, it's likely you've begun recycling paper. Very often, that recycled paper only has print on one side. What about that other side? What about it indeed? For the last couple of years, we've been trying to use both sides of the paper, for writing and computer printing. Rather than putting a (half-used) piece of paper directly into the blue bin, begin a pile of the stuff to put that other side to good use.

I would not, however, use recycled paper for documents I need to mail to government or business offices, or for resumes. Maybe that's just me. But in general, you'll get twice as much use from a sheet of paper.
