Eco-friendly printers


Concern for the the environment he has always had his eye on document and photo printing. On the one hand, the enormous waste of paper in the modern industrialized world implies both an indiscriminate increase in trash (as unfortunately only a small percentage of used paper is recycled) as a decrease in forest resources that are used for the manufacture of said paper. With regard to ink, the greatest concern is with the arrangement of the used cartridges (There has been a lot of recycling effort here which, however, is not enough) and the toxic effects of the ink itself.
A first measure is therefore obvious, and it is the one that is repeated in all campaigns: let's not use the printer except when strictly necessary.
Some additional efforts have been made in relation to the paper saving. Thus, for example, various media have spread the news of a Japanese company named Sanwa Newtec, which created a printer that does not use ink, but instead prints by heat on sheets made of plastic material that are reusable, that is, they are erased and can be reprinted on them. The problem is the cost, since the machine is worth about 5.600 US dollars, and each folio-size sheet about 3,5 dollars.
The big companies dedicated to printing have focused their efforts on the side of improving the raw material for printing. For example, Xerox has released an office printer (due to its price and size they are not yet usable at home) that instead of ink cartridges It uses pieces of a material similar to crayon -as you hear it- with the advantage that there is no residue, but that the "cartridge" is completely consumed.
Other lesser-known companies have launched printers that instead of conventional ink use the well - that is, the remains - of coffee or tea.
In turn, the manufacturers of cartridges and inks are working on what they call eco-solvent inks, that is, they dissolve easily and do not contain toxic substances.
