Laser 'Unprinter' to Boost Paper Reuse over Recycling Last Updated on 2012-03-29 04:02:15 An Article from the Waste Management World Magazine   Image Credit: Shutterstock/Joachim Wendler 19 March 2012 Cambridge University has run successful trails that utilised a laser 'unprinter' to remover toner from paper, leaving it fit for reuse ahead of recycling. According to the University, Dr Julian Allwood, leader of the Low Carbon Materials Processing Group at the University of Cambridge, and David Leal-Ayala, PhD student at the 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 treated higher up the waste hierarchy and be reused - rather than discarded, shredded or sent to a recycling plant. The University claimed that coupled with advances in low-energy... More »
