In a comprehensive research project conducted in close collaboration with industry, researchers at Karlstad University have used data modeling and laboratory and pilot-scale experiments to generate new knowledge that can help streamline the processes. The research project that we just finished focused on improving the efficiency of the dewatering process in the manufacturing of tissue paper, in other words, toilet paper and kitchen roll." Energy-efficient dewatering process in tissue paper manufacturingIn the project, researchers studied through air drying of tissue paper, a technique that is particularly energy-intensive but delivers excellent product properties. "Our project took a holistic approach, where we worked in sub-projects involving data modeling, laboratory experiments and pilot-scale trials.
