For those of you who enjoy a cup of joe with your morning paper, the RITI Coffee printer offers an ingenious way to green your morning ritual: by turning your old coffee grounds into a sustainable source of ink for your printer! One of fifty top entries in this year’s Greener Gadgets Competition, the RITI printer takes the leftover grounds from your morning roast and plugs them into an ink cartridge to create an eco-friendly source of ink. Who would have ever guessed coffee stains could be be so useful!
Jeon Hwan Ju’s RITI printer works by replacing environmentally un-friendly inkjet cartridges with the dregs from your daily coffee. Simply place used grounds in the ink case, insert a piece of paper, and move the ink case left and right to print text. In addition to ridding the printing process of the ink cartridge (it’s most environmentally un-friendly throw-out), the RITI printer also requires a bit of human action to get things going, which eliminates the need for any really significant power source. This last part of the idea seems a bit impractical, but after all that coffee you are drinking, maybe you need some exercise to burn off your excess energy!? Not a coffee drinker? No worries, it works just as well with tea.
