If you are one of those ardent ecology supporters, who love sipping hot beverages (coffee or tea) at regular intervals, here is a concept that will definitely attract your attention. Designer Jeon Hwan Ju has designed an innovative printer that turns your old coffee or tea dregs into sustainable ink source for your printer. Dubbed the ‘RITI Printer,’ the unique printer swaps harmful inkjet cartridges with leftover grounds from your cup of coffee. All, the users need to do is insert a paper in the printer, then put the coffee or tea dregs into the ink case on top of the printer and finally move the ink case left and right to print or draw on the paper. Just pull out the paper from the printer and wash the ink case, when you are done with the printing. The RITI printer not just makes printing eco-friendly but also cuts the cost of printing in a great way.
