Noticing that over 60% of printed documents end up being looked at once before they are thrown away, Friends of Nature set out to create an eco ink.
Branded as Reusable Ink, this eco-friendly printer alternative takes inspiration from a toy doodle pen that fades after a certain amount of time, leaving no messes behind. Similarly, the composition of the ink has been modified so that printing can go on as usual. While the pages might not initially look any different, over the course of a couple days the inks begin to lose their intensity, eventually fading away entirely so that a piece of paper can be reused. For home and office use, this could be a practical solution for documents that you know you won't need to keep around forever.
