But some environment-enthusiast together with their imagination take "green printing" into another level by introducing some innovative concept of futuristic Green Printers:
- RITI Printer Concept by Jeon Hwan Ju
Winning the Greener Gadgets Design Competition with his RITI Printer, Jeon Hwan Ju design concept takes your coffee or tea dregs and turns them into an eco-friendly alternative to conventional ink. To use the RITI printer, you place the coffee or tea dregs into the ink cartridge with some water, insert a piece of paper and move the cartridge backwards and forwards into the slot while drawing on the paper. Using you own kinetic energy to power the process means there is no electricity needed to use this printer.
