Latest Patents

Leena Fagernäs holds a patent for a process titled "Process for concentrating soluble and colloidal substances in process waters." This invention focuses on improving the concentration of fiber-derived dissolved and colloidal substances in process water from mechanical pulping. The process involves treating the water with enzyme preparations that contain mannanase and/or endoglucanase. These enzymes break down soluble carbohydrate polymers into low molecular weight oligosaccharides, preventing an increase in viscosity. This allows for the concentration of process water into a high dry content or reduces the viscosity of previously concentrated water for easier after-treatment. She has 1 patent to her name.
