Abstract

Paper ashes were manufactured from paper sludges collected from a specialty paper mill at different incineration temperatures, and their characteristics (particle size, zeta potential, particle shape, and chemical composition) were analyzed. As the incineration temperature increased, the ash content of the paper sludge decreased, as did the particle size and zeta potential of the paper ash. The paper ash particles were not separated individually but formed agglomerates. The chemical elements Al, Si, and Mg were observed to exist as dioxides. In addition, the properties of the paper ash did not show significant differences according to the type of paper sludge; the ash content alone showed a difference. Therefore, it is important to control the incineration temperature to approximately 700℃ or less and to select high-ash paper sludge in order to acquire high paper ash yields.
