Abstract
A method for disposing of non-polar organic wastes including the steps of dissolving the organic waste in an organic solvent which is not environmentally objectionable, in combination with a suitable surfactant, mixing the resultant solution with a quantity of water to develop an emulsion in which the organic element is effectively dispersed in the water and thereafter mixing the emulsion with cement which, when allowed to solidify, encapsulates the organic waste within the solid cementitious mass. This solid mass is suitable for disposal in a landfill or the like. This invention is useful in safely disposing of environmentally hazardous organic wastes.
