Waste Alkaline Residues Impact in Desertification Treatment in Iraq

Abstract

Waste Cement waste (the by-product of the cement industry) is produced from a dry and wet method for manufacturing cement. These wastes are produced in large quantities from various cement factories that are estimated in tons thrown in the land located in different places of the country, for example, Kufa cement factory in addition to a huge amount of cement dust produced by (450Tons per day) and their influence on the environment. Therefore, a safe method must be found so that can eliminate these wastes because the by-product contains heavy metals and their oxides which are harmful to the human and to the environment especially air pollution and desertification. In this research it has been utilized these wastes as major and minor nutrients for sand soils (major nutrients Ca, K, S, Fe and small nutrients (Mn, Zn, Cu)), cement dust is added in certain proportions to the sandy desert lands. The result showed significant yields by increasing the content of sandy soil from the major and minor nutrients. This enables us to gain a safe environment and solve desertification problem which has a major cause to the environmental pollution
