Abstract
A process for the treatment of waste material. The process includes the steps of combining the waste material with a treatment composition to form crystal growth structures and adsorb 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, dolomitic calcium oxide or calcium oxide or dolomitic limestone, and potassium hydroxide or potassium carbonate. The zeolite seed may be selected from the group consisting of clinoptilolite, chabazite, heulandite, phillipsite or mordenite and mixtures thereof.
