Abstract |
Eleven emerging alternative treatments for polychlorinated biphenyl (PCB) contaminated sediments were compared and ranked using technical performance, status of development, test and evaluation data needs, and cost as factors. In ranking the processes, weights were assigned the factors to emphasise the extent of decontamination, the estimated cost of treatment, and the versatility of the process. The emerging treatment processes are based on 6 technologies: one on low-temperature oxidation (1); 2 on chlorine removal (2); 1 on pyrolysis (3); 3 on removing and concentrating (4); 1 on vitrification (5); and 3 on microorganisms (6). Types of technologies not developed are chlorinolysis, stabilising, and enzymes. The treatment processes were ranked in the order from highest to lowest: KPEG (2), LARC (2), Acurex (4), Bio-Clean (6), Supercritical water (1), Advanced Electric Reactor (3), Vitrification (5), OHM Extraction (4), Soilex (4), Composting (6), and Dybron Bi-Chem 1006 (6). The 1st 8 processes show potential for reduction of PCB concentrations to the desired background levels (1-5ppm) or less, with minimum environmental impacts and low to moderate cost. All the technologies except the advanced electric reactor required further development and testing. |
