Xerox is developing a reusable paper that can be used several hundred times. The paper uses a molecular compound that changes the color of the paper when exposed to UV light. The print fades over 16 to 24 hours when left alone and is instantly erased when exposed to heat, reports Green Technology Forum.
Steve Hoover, vice president with Xerox Research Center Webster, says 50 percent of documents in an office are thrown out within a day of being printed. This ZDNet video provides a demonstration of the disappearing ink.
Xerox's "erasable paper" remains a ways off from being commercialized, but the company has already filed patents on the technology as part of its sustainable innovation initiative.
