ABSTRACT:
A reagent material useful for converting a contaminated waste material, which is environmentally unacceptable, to a relatively harmless granular substance which is environmentally acceptable. The reagent material is comprised of an effective amount of alumina, silica, a hydroxide, or hydroxide precursor, of an alkali metal, calcium oxide, and a medium to large pore zeolitic material. The method involves blending an effective amount of the reagent material with the waste material and allowing it to dry without setting, thereby resulting in an environmentally acceptable particulate substance.
