Electromagnetic paper Recycling system( photo-chromic or thermo-chromic inks?)

Posted: 21 Jan 2011 11:43 AM PST

Hi Everybody :)

Recently I have been thinking on the concept of reusing paper instead of recycling it by using a special kind of photo-chromic ink,
as chemistry is not my profession ia m writing here just to have your opinions about viability of this concept:

what is the concept about?
Concept of Electromagnetic erasing system is inspired from observation of destructive effects of electromagnetic radiation on color pigments. While ink & pigment producers try to increase resistance of pigments in prolonged exposure to sunlight, this project aims to utilize electromagnetic radiation in a fully controlled reaction inside a machine to break the bonds of color pigments that absorb only a particular range of electromagnetic spectrum. In order to have an efficient system only those CMYK pigments should be utilized that their absorption band is different from paper. In this case, in a similar way as a photochromic or thermochromic material, color pigments start to decompose into colorless products however in contrary to what we expect from a photochromic change, electro erasing would be an irreversible reaction.

Here's also the link of the concept for more information:
