Want to save trees? The electromagnetic erasing system might be just the ticket, as it will rub out color pigments in order to deliver white paper sheets. No longer do you need to shred paper then, but if there is a way to erase it, does that mean there is a similar method to reverse engineer the process and restore whatever was erased? Nothing’s impossible in this day and age, but designer Mohsin Saleh’s innovative contraption will definitely offer another alternative when it comes to paper recycling. Basically, it works by relying on an electromagnetic erasing system to rub out all color pigments from a paper sheet. Will this concept ever be realized? One thing’s for sure though, if the process can be reversed, then a paper shredder would still be a staple requirement in offices and homes.
