The Japanese house Ricoch wants to remove the text from useless photocopies and propose a system of use of paper. According to a method being tested, it is about removing conventional laser and fax printed papers and offering the possibility of using them twelve times.

The way it works is simple. When the printed sheet enters the machine it is heated to about 100ºC and then a dissolution is rubbed. The solution softens and releases the ink. The blade then passes through a roller where the dissolution and ink are collected. The prototype that is now being tested cleans three sheets per minute.
