Thermal Treatment Capabilities

Delivering Unique Treatment Ability

Diversified Scientific Services, Inc.

657 Gallaher Road, Kingston, TN - 865-376-0084

Our Diversified Scientific Services (DSSI) facility has the capability to destroy a wide range of low-level radioactive, low-level mixed and TSCA regulated organic wastes using a direct-fired boiler equipped with a specialized burner that can combust the blended waste fuels at a high combustion efficiency. Since the issuance of a Resource Conservation and Recovery Act (RCRA) Part B Permit in 1989 we have thermally treated nearly four million gallons of liquid, totaling over 30 million pounds. This facility operates as the only commercial mixed waste combustion unit in the U.S. with TSCA treatment authorization from the EPA Region 4 to manage TSCA regulated PCB contaminated radioactive wastes. DSSI also has the capacity to store up to 30,000 gallons of liquid waste in our "tank farm", which is used for storage and to allow for blending of the wastes prior to processing. Additionally, DSSI 's on-site fabrication department and research and development laboratory delivers unique treatment capabilities for the most challenging waste streams. Our state-of-the-art engineering practices combined with a deep understanding of RCRA and TSCA regulations, allows us to successfully treat waste that previously was thought to have no disposal path.

Thermal Treatment Option

dssi industrial furnace

Direct-Fired Boiler Industrial Furnace

For decades, DSSI's boiler has provided compliant and effective final destruction of liquids separated from solid wastes. This boiler thermally treats radioactive, mixed, and TSCA-regulated waste, ensuring safe and efficient disposal. The combustion residues are treated to meet LDR compliance standards. Additionally, the steam produced powers a generator via a steam turbine, making the boiler a waste-to-energy recovery unit. Capable of co-wasting water, oils, solvents, corrosives, and organic-bearing liquids and semi-solids, it remains the only commercial mixed waste combustion unit in the U.S. authorized by EPA Region 4 to treat TSCA-regulated PCB-contaminated wastes.
