High filler loading and energy saving without forgiving any physical property loss in printing paper is a long-cherished wish for papermakers because reduction of production cost and carbon dioxide emission are expected. In this study, the fines generated from wood pulp were covered with calcium carbonate (CaCO₃) by the in-situ calcium carbonate formation method with the fines to calcium carbonate ratios of 1:10, 1:30 and 1:50, and were used to prepare handsheets. The handsheet results revealed that the CaCO₃ covered fines by in-situ method improved breaking length, bulk, stiffness and double folds greatly compared to the control, where ground calcium carbonate (GCC) were added to fiber furnish, at equivalent ash levels. Lowering reaction temperature of in-situ CaCO₃ formation from 40°C to 20°C deteriorated most of strength properties.

Wood flours can give high bulk and high stiffness in paper, but low brightness and low smoothness may prevent them from wide utilization in printing paper. Hydrogen peroxide bleaching and in-situ calcium carbonate formation on wood flours were compared in this study to find out the possibility of using either of them in printing paper. The results showed that the in-situ calcium carbonate formation method on wood flours had better possibility than bleaching method in respects of better smoothness and higher brightness in paper properties. Much higher yield and no water contamination were the economical advantage of using the in-situ CaCO₃ process on wood flours.
