Here we have another concept eco-printer, the REENK by Hyo Sun Ahn & Min Koung So. Similar to the Pencil lead printer, the REENK uses the leftover ink from ballpoint pens after they stop working. The only flaws I can see with this design is that you would probably have to buy specific CMYK pens that would probably be more expensive than your avarage ballpoint pen, and when have you ever used a yellow pen? The concept is still a great one though.
I bet that at some point in your life you’ve wondered what would happen if you put an ink cartridge in a microwave. Actually the though probabily has never crossed your mind, but I’m going to show you a video of someone microwaving a cartridge anyway. (Don’t try this at home)
It’s roughly how I imagined what it would look like, a burning plastic mess in a microwave.
In case you’re wondering just what to do with your empty ink cartridges, we’ve come up with a few fun do’s and don’ts.
