One of the unwanted by-products of the use of computers is that they leave in their wake a mountain of waste paper. As we strive for perfection in reports, letters and other publications, we print out draft after draft, ending up with masses of scrap. Try as we might, we can only utilize so much of this as stapled-together rough notepads, or for our children to create their stunning art work upon. Also much of it may have to be shredded if it of a confidential nature.
