A team of researchers at the University of Cambridge has come up with an innovation that can “unprint” something. By using long and ulstrashort pulsed lasers, the technology can remove laser-printed content, leaving the paper clean and undamaged. The paper can easily be reused and printed on again. According to reports, the new technique could be 20 times more efficient than recycling and more eco-friendly as it only emits half the carbon emissions.
