Coffee grounds turned into printing ink

This year's Greener Gadgets Deesign Competition from South Korean designer Jeon Hwan Ju designed this green printer RITI, the concept is really worth recommending and promoting. It is really troublesome to change ink cartridges for printers. If you don't handle them properly, you may even earn a lot of ink. This RITI printer is environmentally friendly and convenient: all you have to do is put coffee grounds in the printer's ink cartridges and put paper in the middle.

How to use it:

1. Put the paper into the printer

two。 Put the coffee residue into the ink cartridge at the top of the printer.

3. Move the ink cartridges on the printer left and right

4. When the printing is complete, take the paper out of the printer and wash the ink cartridges clean.
