Currently, there has been a move in the pulp and paper industry to reduce or eliminate chlorine-based bleaching due to environmental concerns. The POZONE process, a chemical means of ozone production, has been used to bleach wood pulp. The brightness, Kappa number, and viscosity of wood pulp subjected to POZONE treatment have been determined. Brightness increases of up to 44 points and Kappa number decreases of as much as 22 points have been achieved. Promise for effective industrial application has been demonstrated.
