it turns out that reusing paper is easier on the environment than recycling it, that’s probably why the folks at Tree Hugger are giving the un-printer some ink. “Wide use of this technology could have a huge impact,” they predict. “Reusing paper could reduce emissions by 50 to 80 percent over paper recycling.” Recycling involves trucking it to a plant for sorting, mixing it with water to make a slurry, and then spreading it with huge rollers to make “fresh” paper.
