In-Pile Thermal Desorption® (IPTD®) Animation at Danang Airport, Vietnam

In February 2013, the U.S. Agency for International Development awarded a $37M contract to TerraTherm to carry out thermal remediation of dioxin at Vietnam’s Danang Airport. TerraTherm’s remediation technology is playing a vital role in the U.S.-funded project’s efforts to clean up dioxin contamination in areas of Danang airport where herbicides were stored and handled during the U.S.-Vietnam War. USAID is working in close coordination with the Government of Vietnam and other contractors to implement this ongoing project through 2016.

USAID selected TerraTherm’s In-Pile Thermal Desorption® (IPTD®) technology for treatment of approximately 73,000 cubic meters (95,000 cubic yards) of soil and sediment at Danang Airport. The IPTD® approach involves placing contaminated soil and sediment within an above-ground, covered and fully insulated treatment pile structure, and then heating each batch of soil over several months to destroy the dioxin. Once implemented, the technology can safely and effectively treat the soil to the required Vietnamese cleanup levels, as has been demonstrated at similarly-sized projects in the United States. TerraTherm is working with Krüger/VWS-VN to implement the project.

USAID commissioned a video animation to help explain to the public how the IPTD® system works.
