Physicochemical and Environmental Characterization of Industrial Wastes in Powder

Abstract

In the present work residual powders of diverse industries are characterized from the environmental and physicochemical point of view, in order to determine the properties of them and establish the feasibility of reutilization or recycling. Cinders of additives, waste of scrap shredding process, LD converter steel slag and other powders of industrial processes were characterized by using optical and electronic microscopic techniques, semiquantitative chemical analysis, particle size distribution, X-ray diffraction analysis, thermal and thermogravimetric analysis, leaching test, among others. As a function of the obtained results some possible ways for recycling or reuse of these residual powders were proposed.
