The rise of electronic communications is indirectly making it ever harder for manufacturers to satisfy Americans’ preference for soft toilet paper, says a new report. But the paper purveyors are hoping the problem can be solved through clever chemical engineering.
The developments are detailed in an article in the April 19 issue of Chemical and Engineering News, an American Chemical Society publication.
Low-priced soft toilet paper comes largely from recycled office paper, but the rise of e-mail and paperless communications means used white office paper “is getting increasingly hard to find,” wrote Melody Voith, senior editor of the publication, in the article.
The shortage of used office paper as well as newsprint is affecting other sectors of the paper market as well, the article adds. A shortage of recycled paper can be made up with paper from freshly chopped trees, but this is costlier and tougher on the environment.
Paper from “virgin” trees is the highest quality and contains long fibers from the cell walls of plants. As paper is recycled one or more times, the fibers are progressively broken down and weakened, and the paper quality diminishes.
The recycled office paper used to make toilet paper itself contains increasing amounts of recycled paper, Voith explains. That decreases its usefulness for making high-quality personal paper soft enough to satisfy picky consumers.
“To keep costs down, papermakers are using lower and lower grades of recycled fiber and attempting to make higher grades of paper with it,” Voith wrote. “The trend has created a growing niche for functional chemicals that improve aspects of paper quality including strength, water repellency or absorbency, softness, smoothness, color and brightness, and printability.”
