Abstract: The importance of fly ash in industrial applications is continuously increasing. This research focused on the production of novel calcium silicate filler made from pulverized coal fly ash and its application as a filler for fiber replacement and improved study properties in the newsprint industry. The results show that its effect on retention, drainage and study properties are very significant as compared to PCC filled newsprint sheet and control way of manufacturing newsprint in India. Results also show that tear index, gurley stiffness of fly ash based newsprint sheet is better than PCC filled sheet and control newsprint shee, whereas brightness and opacity of fly ash based newsprint is also increase contrary to various literature that increasing fly ash based filler in study decreases the brightness and optical properties of newsprint sheet. One of the most profound impacts on the increasing in the First Pass Ash Retention (FPAR) from nearly 30-70% and First Pass Retention (FPR) increasing from 93-99% in fly ash based filled newsprint sheet as compare to control filled newsprint sheet. To the researchers knowledge, this is the first study reporting the application of fly ash as a filler for quality enhancement of newsprint.
