[email protected]. THE USE OF OLD CORRUGATED BOARD IN THE MANUFACTURE OF HIGH QUALITY WHITE PAPERS by Rene' H. Kapik A Thesis submitted in partial fulfillment of the course requirements for The Bachelor of Science Degree Western Michigan University Kalamazoo, Michigan December, 1983 ABSTRACT Clean corrugated board waste was fractionated into its softwood/ hardwood fiber components, repulped using a kraft pulping process, and bleached using a CEHD bleaching sequence in an effort to produce high brightness fiber suitable for use in medium to high quality white paper. The papers produced had almost equivalent mechanical strengths and opacity, but possessed unsatisfactory brightness and cleanliness when compared to commercially manufactured,:. bleached kraft pulps of identical softwood/hardwood contents. Based on this experimental data, the use of recycled fiber from corrugated board as a fiber substitute in the manufacture of high quality printing and writing papers is not recommended due to its inferior brightness and cleanliness.
