A method of converting hazardous industrial and other wastes into an inert, non-polluting and useful soil-like product. ABSTRACT OF THE DISCLOSURE When bentonite clays and portland cements are mixed with aqueous solutions or with mixtures containing polluting materials, a solid mass is formed. The quantities of bentonite and cement control the consoli- dation of materials and govern physical factors, such as the hardness and the chemical characteristics of the resultant material. This resulting product is chemically and physically stable; a solidified product which is almost completely insoluble in water, and in which, pollutants are encapsulated in the matrix so that the waste material is rendered non-polluting and fit for ultimate disposal.
