News // DGE involved in Dioxin Project in Vietnam

Date // 11th June 2012

Kalmar, Sweden

Together with Umeå University, CECS (Center of Environmental Conservation and Chemical Safety) and Cleantech Co Ltd, DGE has initiated a project to share experience and knowledge between Sweden and Vietnam regarding dioxin contaminations and other POPs (Persistent Organic Pollutants) in soil. The project is partly financed by SIDA (Swedish International Development Cooperation Agency).

In Vietnam there is a big issue concerning dioxins, as a result of the U.S. use of pesticides particularly in southern Vietnam between 1961 and 1971. More than 80,000m3 of pesticides containing dioxin (including Agent Orange) was used to defoliate jungles and destroy crops. Today the project is running in three hot spot areas in Vietnam where high amounts of dioxins have been found. The areas are all located nearby airports where the refuelling of the planes is carried out. The project, which is financed by FN (UNDP) and USA (USAID), has included full scale testing of interesting techniques MCD (Mechano Chemical Dehalogenation) and IPTD (In-Pile Thermal Desorption) for the remediation of contaminated soil.

The idea of this project is to benefit from the experience in Vietnam so that knowledge can continue to be used for future remediation in Sweden, where dioxin contamination can be found by old sawmills. Furthermore, Swedish knowledge about dioxin, and its behavior in soil and groundwater and risk assessment of contaminated sites can be transferred to Vietnam.
