Invent for ink removal on paper for 5 minutes

Researchers at Rutgers University, New Jersey, USA have found a way to erase ink printed on used pages, allowing a piece of paper to be reprinted many times.

According to Gizmodo , researchers at Rutgers University's Department of Mechanical and Aerospace Engineering have recently discovered a new way to make paper recycling more efficient and less expensive.

Accordingly, they use pulses of light from a xenon lamp to remove black, green, red and blue inks without recycling.

This technology is often used in cosmetic procedures such as hair bleaching, according to a research report published in the Journal of Cleaner Production.

Previously there were solutions to recycle printed paper without the need for complex processing, but mainly based on the type of ink produced by a special formula, dedicated to this. The ink will disappear during intense heat or laser treatment with used paper.

However, this particular ink as well as the cost of upgrading the printer with integrated laser technology to evaporate ink are often high, so the plans for such paper reuse are still not popular.

Meanwhile, the new method of scientists at Rutgers University can be applied with old-style printing paper, using standard printing ink that has been used in popular printers and copiers today.

However, the new method is still limited to the long processing time . To remove the ink of a page in this way takes 5 minutes. But in a positive way, it helps reduce the amount of paper used, as well as reducing the amount of paper used to recycle.
