Our DSSI facility has the capability
to destroy a wide range of liquid mixed and radioactive wastes using a licensed
combustion process. The DSSI facility has over a decade of mixed waste treatment
experience, since issuance of a Resource Conservation and Recovery Act (RCRA) Part
B Permit in 1989. This facility operates the only commercial mixed waste combustion
unit in the United States with TSCA treatment authorization from the EPA Region 4
to manage TSCA regulated PCB contaminated radioactive wastes. This authorization
is the first and only commercial outlet for radioactive PCB waste treatment and
disposal that had not previously been available to commercial generators. The DSSI
facility is complementary to other Perma-Fix treatment facilities and provides final
destruction of liquids separated from solid wastes. The contaminants in the waste
are either completely destroyed or bound to meet land disposal restrictions (LDR)
criteria. Perma-Fix disposes of all combustion byproducts and no secondary wastes
are returned to the customer.
To expand the types of wastes acceptable for processing through the combustion system
a liquefaction unit is employed. Solid or semi-solid materials can be converted
to a liquid state using high shear mechanical mixers, homogenizers, and mills. The
materials are reduced in size and create a colloidal suspension with the free liquid
resulting in a pumpable liquid waste that can be combusted in accordance with EPA
