The projekt "Dissolved and colloidal substances in papermaking (DISCO)" seeks new knowledge on components in papermaking at the molecular level.This will improve the understanding and facilitate technical control of wet-end chemistry, particularly in the production of wood containing papers.Modern analytical techniques are applied and further developed.New means of reducing the detrimental effects of the dissolved and colloidal substances are investigated in close cooperation with paper mills and suppliers of papermaking chemicals.
