Here’s another eco-friendly gadget in the form of a printer. Known as the RITI Coffee Printer by Jeon Hwan Ju, this smart device will turn your old coffee grounds into a sustainable source of ink for your printer, meaning it will replace the environmentally un-friendly inkjet cartridges with the dregs from your daily coffee. Pretty innovative! Sadly, it’s just concept at this stage, but hopefully this will come to market sooner rather than later. [Inhabitat]
