Shimizu Corporation is working with Vietnamese government agency “NACCET”
National Action Center for Chemical and Environmental Treatment: Responsible for environmental issues throughout Vietnam.
An on-site type soil cleaning plant and cleaning treatment test was completed at a verification test of dioxin-contaminated soil derived from defoliants at Bien Hoa Airport.
“A report showing that the decontamination effect was confirmed as originally expected” was submitted to the government agency.
Demonstration test: purification of contaminated soil
It complies with the technology selection process of the soil remediation project (promoted by the Vietnamese government and the US government) for Bien Hoa Airport.
The two governments will consider whether to adopt a full-scale decontamination project that will start in June 2020.
In Vietnam: Vietnam War
Dioxin-contaminated soil derived from defoliants sprayed by the U.S. military is largely left in the country.
Bien Hoa Airport has the largest dioxin-contaminated soil in the country, reaching 850,000 tons、
Shimizu Corporation: Soil cleaning technology
In 2014, we started a survey of “Applying soil cleaning technology with a proven track record in Japan” to contaminated soil derived from defoliants in Vietnam. .
In June 2018, a memorandum of understanding was concluded with NACCET’s predecessor organization, CTET (CENTER FOR TECHNOLOGY OF ENVIRONMENTAL TREATMENT), for joint implementation of demonstration tests.
