How it Works
The ink works in ordinary inkjet printers, using ordinary paper. The printing process itself is unchanged, but after the use the paper is not discarded or recycled. Instead the paper is set aside and the printing erases itself.
Carbon dioxide in the air is absorbed by the ink and chemical reactions take place that make the ink colorless.
When this “self-erasing” is complete, the paper is indistinguishable from new paper and can be used again exactly the same way new paper can be used. When the paper eventually becomes wrinkled after many uses it can be recycled as normal.
