A method of disposing of hazardous volatile liquid organic waste materials that includes the steps of providing a dry free flowing solid material containing lime and preferably, an organic salt of calcium, magnesium or aluminum containing about 10 to 22 carbon atoms; stirring a volatile organic liquid waste material to be disposed of therein to form a non-aqueous paste; allowing the paste to harden into a solid form that does not release the waste liquids when 100 grams thereof are placed in a 400 micron conical paint filter for five minutes: and, burning the resultant solid whereby the volatile material is burned and any hazardous metallic impurities remain in the resultant lime-based ash. The preferred organic salt component is calcium stearate.
