Use a laser, save a tree

Laser un-printers that can remove toner from scrap paper so that it can be used again may be coming to an office near you in the future, results from a new Cambridge study show.

Dr Julian Allwood, Leader of the Low Carbon Materials Processing Group at the University of Cambridge, and David Leal-Ayala, PhD student at this group, tested toner-print removal from paper by employing a variety of lasers.

The results showed that toner-print can be removed effectively without causing significant paper damage, allowing the paper to be reused, without being discarded, shredded or sent to a recycling plant.

Coupled with advances in low-energy laser scanning technology, copiers and printers, the research means that toner-removing devices may be a common sight in offices around the country in the future.
