In-situ CaCO₃ formation on recycled wood pulp was studied to improve optical property and filler attachment to the fiber furnish in papermaking. We tried to attach calcium oxide (CaO) to the recycled fibers, old newspaper (ONP) in this case, by using selected polymers before in-situ CaCO₃ formation reaction on fibers, and then, CO₂ was injected to the furnish until all the CaO on fiber surfaces was consumed. It was found that the attachment of newly formed CaCO₃ to recycled fibers became stronger by attaching CaO to the fibers before in-situ CaCO₃ formation reaction. It was expected that the polymers used for the attachment of calcium source to the fiber furnishes helped to keep the newly formed CaCO₃ strongly attached to the fiber surface as well as to retain the impurities associated with calcium source and recycled fibers, if any. In-situ CaCO₃ formation gave higher brightness and much less ERIC value in ONP sheet than the case when the equivalent amount of GCC was added to the furnish.
