Xerox strives for an 'erasable paper' system for copiers.
John Markoff, International Herald Tribune, November 27, 2006
Xerox is working on a chemical process that would allow its copiers to recycle paper documents, possibly an unlimited number of times.
In most modern offices, paper increasingly is used as a medium of display rather than of storage, according to Brinda Dalal, an anthropologist at the Palo Alto Research Center
where she and the Xerox chemists are developing an "erasable paper" system.
The researchers said that individual pieces of paper had been printed upon as many as 50 times, and the only current limit in the process appears to be stamina of paper.
