Abstract: A process for the treatment of waste material is disclosed. The process includes the steps of combining waste material with a treatment composition to form crystal growth structures, and adsorbing the waste material within the crystal growth structures, thereby stabilizing the waste material. The treatment composition includes natural zeolite seed, crystalline quartz, aluminum trihydrate, sodium carbonate or sodium hydroxide, and optionally dolomitic calcium oxide or calcium oxide or dolomitic limestone, and potassium hydroxide or potassium carbonate.
