CA University Researchers Are Working on Rewritable Paper That Prints by Using UV Light

Scientists are redefining what it means to go paperless. Researchers at the University of California, Riverside, have been working on an alternative to traditional paper that can be printed on and erased more than 20 times. Its low-cost production could help reduce waste, deforestation, and chemical pollution, according to chemistry professor Yadong Yin, who copublished a paper on the design in Nature.

"If we are comparing the rewritable paper to conventional ones, it has the advantages of being more economical, environmental, and energy friendly," he said.

The scientists expect the rewritable paper to go into commercial production in a few years.
