In-pile thermal desorption of PAHs, PCBs and dioxins/furans in soil and sediment

Current overall treatment costs for soil and sediment heavily contaminated with Semi-Volatile Organic Compounds (SVOCs) such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polychlorinated dibenzodioxins and furans (PCDD/Fs) can be as high as $550-770 per metric tonne. This paper focuses on an innovative thermal treatment method that is likely to be highly effective at full-scale costs of less than one third ($110-330 per metric tonne depending on total volume). TerraTherm’s In-Pile Thermal Desorption (IPTD) technology is an ex-situ version of In-Situ Thermal Desorption (ISTD), by which TerraTherm utilizes simultaneous
