Abstract
A process for solidifying organic waste in cement for transport and storage in solid form by mixing organic waste, water, and a cationic amine to form an emulsion, mixing the emulsion with cement to form a mixture without breaking the emulsion, casting the mixture in a form, and curing the mixture to a solidified form. In a preferred embodiment of the process, a particulate material with a negative surface charge is included in the mixture to neutralize positive charges on the cationic amine and the cement. An alcohol or glycol may be included in the emulsion to enhance the holding power and integrity of the emulsion by controlling size and uniformity of emulsion particle size. The process is applicable to organic wastes such as waste oils, halogenated solvents, non-halogenated solvents, pesticides, herbicides, liquids and sludges containing heavy metals, radioactive mixed wastes and mixtures thereof.
