Anyone who runs a paper machine at 1,400/m/min knows that breaks come with the territory. Any means of minimizing them is taken seriously. To reduce breaks on their PM 4 newsprint machine, they decided to break with tradition, explains production manager at UPM Kajaani mill in Finland, Kalle Luomi. Instead of using organic biocides in the process water, they switched to chlorine dioxide (ClO2), produced by a small on-site generator. For close to two decades Kajaani's PM 3 and PM 4 have won the business to supply special newsprint papers to Japan for 'manga' comic strips and books. Japanese printers have a low tolerance for imperfections in the sheet, especially the number of holes. Once their new chlorine dioxide system was in place instead of traditional biocides, breaks dropped, and quality rose. All of them knew that they were doing the right things, based on their willingness to look at the process a little differently.
