PCB Removal Solutions

A spectrum of industrial solutions have been invented allowing PCB destruction. The United States Environmental Protection Agency (USEPA) evaluates these commercial technologies and determines them to be either Established, Demonstrated or Emerging Technologies. The most exciting advances lie with the Demonstrated and Emerging Technologies.

Technologies classified as established “are those that have been employed at the full-scale level to successfully meet PCB cleanup goals at multiple sites and are commercially available” .These technologies include: Super-Critical Water Oxidation (SCWO), Base Catalyzed Dechlorination (BCD), Glycolate Dehalogenation (APEG Plus), Plasma Arc Centrifugal Treatment (PACT), Plasma Arc System (PLASCON), Plasma-electric Waste Converter (STARTECH), Molten Metal Pyrolysis, Chemical Reduction (ECO LOGIC), and PCB SonoProcess^TM Technology.

Demonstrated technologies have been conducted at pilot- or full-scale at a limited number of sites. They have generated performance and cost data on the treatment of PCB-contaminated soil or sediment and include: Molten Salt Oxidation, Solvated Electron Technology (SET™), Catalyzed Electrochemical Oxidation (CEO), Catalytic Hydrogenation (CSIRO Process), Solvent Extraction, and Dehalogenation by Mechanochemical Reaction (DMCR).

Emerging technologies have not yet been shown to effectively or consistently treat PCB-contaminated soil or sediment at the pilot scale level. They are in bench-scale studies or in pilot-scale testing stages of PCB-contaminated soil or sediment” and includes: GeoMelt™ Process, Advanced Oxidative Process, Solar Detoxification, Thermal Desorption Integrated Technology, and RPI Bacterial Degradation, in which Dehalococcoides species are used to dechlorinate PCB material. These bacteria were isolated from the Housatonic River, a site with a high concentration of PCB content and where bacterium have developed a unique biological method of biodegradation.

Many of these methods have considerable PCB destruction capacity. For some processes there is a requirement for substantial capital investment, high energy consumption and high temperature demands, and disposal of contaminated materials is still required.

Dynamic Adsorbents Inc. (DAI) has formulated a specialty proprietary adsorbent (Alumina C) allowing PCBs to be removed safely from contaminated sites that offers several advantages over other solutions. More
