  3. Commercial technologiesfor PCB treatment

  4. TECHNOLOGIES FOR HIGH CONCENTRATED OR PURE PCBs

  5. Technologies forlow-MediumconcentratedPCBs (i.e. up to 10000 ppm )

  6. DecontaminationTargets

  7. Requisitesfordisposaltechnologies under the SC

  8. BAT and BEP under the Stockholm Convention

  9. Efficiencymeasurement: DE and DRE

  10. NEED TO PERFORM Trial burn tests Trial burn with PCB contaminated soil (PCB 1-2%) Trial burn with PCB oil (PCB 20%) Trial burn with PCB soil and capacitors (PCB 10%) DE / TEq test trial burn with PCB soil and capacitors (PCB 10%)

  11. Pre-treatment

  12. Pre-treatment and feeding

  13. Inherently and demonstrablysafe

  30. Need for an LCA Approach in PCB management • Trial burn test 1 (PCB contaminatedsoil, PCB 1-2%) • PCDD/F 0.104 ngTEq/Nm3 • Trial burn test 2 (PCB oil, PCB 20%) • PCDD/F 0.042 ngTEq/Nm3 • Trial burn test 3 (PCB soil+capacitors, PCB 10%) • PCDD/F 0.080 ngTEq/Nm3 • MinimizereleaseofPOPsfrom the wholeprocess !! Site cleanup Transportation and Storage FinalDisposal

  31. Plasma

  32. Plasma (Cont’d)

  33. Transportable plasma plant

  34. Retrofilling

  35. COST FACTOR FOR Retrofillingcycles Decontamination trends with retrofilling, starting from different concentrations. For pure PCBs, at least 6 cycles are required to bring PCBs contamination below 50 ppm
