Clock | This ‘unprinter’ sucks ink to make paper reusable, could transform carbon footprint of office printing

Scientists have created a miraculous device that removes ink from printer paper, allowing each sheet to be reused ten times. By reducing demand for office paper, they want to reduce the amount of carbon dioxide (CO2) emissions that cause climate change in the pulp and paper industry. Specially coated paper, which prevents ink (or powdered toner) from penetrating the sheet, is the secret of so-called “unprinting”.

The ink is then vaporized by a powerful laser. Circular printing is as explained by Barak Yekutiely, the lead developer of REEP Technologies in Israel. Large volumes of globe-warming carbon dioxide are produced during the production of various essential goods that sustain our lives, from paper to plastic.

The REEP method completely removes all the ink from the paper using state-of-the-art laser technology. The basis of Reep’s solution is laser printing together with state-of-the-art materials that allow paper to be reused. It is the first deprinting technique to pass the renowned Ingede de-inking test with a perfect score.

RCP, or Reep Circular Print, is a service that provides REEP capability. The consumer receives Reep deprinters, reusable paper, and full support for an all-inclusive per-click charge. Reep’s services eliminate the requirement to purchase, store, collect, shred and recycle single-use printer paper.

Since the invention of the printing press, REEP is promoting a circular economic model for the first time. Reep technology dramatically reduces resource use and carbon emissions associated with office printing by more than 90 percent. Tree maintenance will increase carbon sequestration, improving the climate through printing operations.
