The main stages of the production of organomineral cellulose composite materials (CCM) for informational purposes (office types of paper) have been examined. The possibility of transfer to a resource-saving adaptation technology by molding paper from a mixture of partially bleached cellulose, bleached chemical-thermomechanical pulp and a mineral filler — precipitated calcium carbonate (Precipitated Calcium Carbonate — PCC) — with the creation of a new type of office paper — ECO paper, is shown. The change in the nature of inter-fibrillar and inter-fiber bonds during the transition from bleached cellulose to partially bleached was analyzed. The morphological features of these semi-finished products, as well as the optical and physic-mechanical properties of the resulting paper have been studied. The problems of directional changes in the zeta potential of the paper mass are identified when the nature of paper-forming fibers changes. On an industrial papermaking machine (PMM) with a capacity of more than a thousand tons per day, pilot production and transfer of PMM to mass production of new types of paper, with appropriate addition of existing standards, were carried out.
