In order to improve the refresh rate of old newspaper(ONP), PCC shape-controlling experiments were carried out. The effect of a PCC polymorph on improving the quality of old newspaper was studied for a transformation from waste paper to eco-friendly paper. The synthesis of PCC consists of an in-situ process and a loading process to enhance the refresh rate of old newspaper. The characteristics between the in-situ process and the loading process could be analysed by SEM analyses of coated fiber surfaces. The retention rate ranges from 65 to 67% after the application of the in-situ process, and that after the loading process ranges from 55 to 58%. The retention rates thus show a difference of about 7-10%. In addition, the whiteness and ERIC characteristics of the in-situ process gave more efficient results than those of the loading process.
Key words: Whiteness, Old news paper, Precipitated calcium carbonate
