Abstract

Characteristics of pulp and paper mill solid wastes depend generally on the raw materials, stock preparation process as well as wastewater treatment plant. In order to determine the best application of paper mill solid wastes, physicochemical properties of solid waste produced in the Mazandaran Wood and Paper Industry Co. and Latif Paper Co. were analyzed. The dry content, pH, fiber dimensions, composition of organic and inorganic compounds of the both solid were analyzed. The dry content of the produced wastes in Latif and Mazandran were determined as 69.3 and 36.7 percent, respectively. The pH of both wastes was close to neutral (pH/7.0). The fiber  length of  Latif and Mazandaran wastes were 1.68 and 1.08 mm, respectively. In addition, the total amount of carbohydrates, glucose and mannose quantity in the Latif waste were determined as 48.09, 29.5 and 7.2 percent that were higher than that of Mazandaran waste. In the contrary, the lignin, xylose and galactose content of Mazandaran waste were determined as 15.3, 17.3 and 3.7 percent that were higher than those of Latif waste. The mineral content of Latif and Mazandarn wastes were determined 44.7 and 39.5 percent, respectively. XRF analyses revealed that the predominant elements in the incinerated ash of both wastes contained calcium oxide, aluminum oxide and silicon oxidethat can be used as raw material for lightweight concrete and zeolite synthesis.
