  • To apply paper mill sludges to soil as fertilizer, paper mill sludges were investigated to predict suitability and maleficence for soil. Newspaper and Printed Paper sludge were analyzed by IC (Ion Chromatography) and ICP-OES (Induced Coupled Plasma Optical Emission Spectrometer). As a results, harmful materials in two types of sludges were below standard by notified Ministy of Environment (ME). Also ionic substances causing the water pollution in sludges were less than the standard value by notified ME. Thus sludges from newspaper and printed paper is presumed that there are no water pollution and soil contamination.
