ABSTRACT:
A process for an article of encapsulated waste which is acceptable for transportation and storage is prepared by whereby the contaminated solid is contacted in a bath of a molten paraffinic hydrocarbon encapsulating material for time sufficient to expel moisture and to coat the solid rendering the contaminant immobile, isolated and unleachable into the environmental system once the paraffin has solidified. An embodiment of this invention employs a zeolite to absorb liquid wastes expelled from the solid which remains in the article.
