Erasable Paper?

13WHAM-TV: Photocopier paper that erases itself hours after it’s been used? It’s in the works.
Xerox researchers are testing it at a lab near Toronto Canada. The Xerox Research Center of Canada is one of five global centers. The Center in Canada focuses on the future of the document, inks, toners and imaging. It’s also the place where self-erasing paper was developed.
The paper looks ordinary enough, but what you can’t see is what makes the technology cutting edge. Dr. Paul Smith said, “It doesn’t use toner or ink….in 16 to 24 hours it turns from black to colorless again.”
Erasable paper works when combined with a special printer. A certain wavelength of light reacts with the coating on the paper to create the image.Xerox researchers say erasable paper is best used for pages you don’t need to keep around like emails, daily calendars, and fax cover pages.
Researchers found that two of every five pages are kept for less than a day, and then recycled. So, Xerox says, its product will reduce paper waste.
This is still a research project, which means it will be years before it will lighten the load of the recycle bin.
