The scientists from Lawrence Berkeley National Laboratory and Shandong University in China have developed a new type of paper that can be printed with ultraviolet light, erased by exposure to heat and then rewritten more than 80 times. If brought into commercial application, this paper might address the concern about deforestation, pollution and waste generation related to the paper industry.

The new variant is produced by coating the conventional paper with a layer of non-toxic titanium dioxide nanoparticles that respond as the photons from the light hit the surface, writes BT.com. One of the scientists claims that the technology is a better, cheaper alternative to recycling paper and also saves trees.

The scientists have also developed a prototype printer for this kind of paper, and they claim this printer would be simpler to manufacture and maintain as it is free from the moving components found in laser or ink-jet printers, notes Seeker.
