  • Patent number: 4863638
    Abstract: A process for containment of hazardous waste is disclosed including initially encasing the waste material into a plurality of containment vessels each of which includes a coding on the exterior thereof to indicate the type of hazardous waste therein retained. The containment vessels are then secured with respect to one another into a grouping of 2 to 8 such vessels. The grouping is then entombed within a plastic casing to further prevent leaking of hazardous waste material outwardly from the vessels. Finally a handling device is attached with respect to the plastic casing to facilitate movement thereof. The individual containment vessels preferably are metal cylindrical drums and can be lead lined to facilitate retaining of low level radioactive waste therein. Preferably the grouping of containment vessels are banded together with steel banding.
