Coffee Ground Printer
Most people enjoy a cup coffee every morning to get them going. If you are composting your coffee grounds you are already off to a good start. But what else could we do with those coffee grounds you might ask? The folks over at RITI found just the thing with their invention of the RITI Coffee Printer. Yes indeed, they have found an ingenious way to turn your old coffee grounds into a sustainable source of ink for your printer. Too good to sound true you might think, who would think that coffee stains could be considered useful?
According to the description page at Greater Green Goods all you have to do is the following:
1. Insert a paper in the middle of the printer
2. Put the coffee or tea dregs into the ink case on the top of the printer
3. Move the ink case left and right as you draw on a paper
4. When the print finishes, pull out the paper from the printer and wash the ink case
Pretty darn Cool.
