A process for treating contaminated waste to stabilize environmentally harmful heavy metals. The waste is contacted with a mixture of a sulfide, preferably calcium sulfide, an inorganic phosphate, which prevents oxidation of sulfide, and a base that at least includes calcium hydroxide. The process stabilizes harmful, heavy metal materials in the waste but avoids the prior art disadvantage of emitting hydrogen sulfide.
