Lignosulfonate profiles in the neutral sulfite semi-chemical (NSSC) pulping process and effect on the anaerobic treatment of wastewater

Lake Utopia Paper is interested in developing and improving the birch NSSC pulping process for the production of corrugating medium. The primary objective of this project is to develop delignification and sulfonation models for process control of NSSC pulping of birch. In addition, the relationship between the NSSC pulping process and the properties of the final product (pulping efficiency, yield and pulp properties) will be established. Through further development of the NSSC pulping process, it will improve the economic performance of the company and allow them to remain competitive in the international market. The result from this research project will not only benefit the Lake Utopia Paper, but also other Canadian Pulp and paper industries.
