This "de-printer" tech uses a specially coated paper, which stops ink soaking into the page. A powerful laser then vaporises the ink so that the paper can be reused up to 10 times.
I am to old. But my question on this, have they studied the chemical analysis of the vaporizing of the ink off the paper. It's not like the ink just disappears into nothingness. We all should know at this point in time, that it just changes shape and is broken down into smaller pieces. Is that better or worse than the CO2 for making paper. I don't have that answer, I've been in printing too long smelling the press room chemicals to know.
If you believe the hype.. That CO2 (Less than one half of one percent of atmos gas.) has any more than a tiny fractional effect on global warming. Versus.. for example.. Water vapor.. (Clouds) (Yeah.. Huge effect) While CO2 (plant food) has had a tremendous effect on greening the the entire world and growing bigger and better crop yields. OK done. [Steps down from soap box.]"They aim to cut the amount of planet-heating carbon dioxide (CO2) emissions from the paper and pulp industry by reducing demand for office paper."
