Phytoremediation of Contaminants > Dioxins

Plants As Water Protectors for Toxic Cleanup. @EPA @EPAregion7 @DOESBIR I have solutions to help clean the #OhioTrainDisaster Water Issues. Why is it so hard to work w/ your organizations??? https://t.co/lI3ogWMtMo

@cureworks @Grow_Fruit_Fl @GypsyMajik1122 @EPAregion7 @EPA @DOESBIR @NHLBI_SBIR > Tell me why this cannot be done? Is it too simple? The #pollutionsolutions are available. lets get to work and cleanup the chemicals destroying our planet. https://t.co/McBKm8OY00

Here is what I DO NOT understand about the #EPA.

They have and list all these solutions to the problems on their own websites and do not use their own published science articles.

Who is the @EPA @EPAregion7 really trying to HELP? https://t.co/jXoYlPTuTq

Dioxins

Treatment Technologies

When cleanup began at the Times Beach, Missouri Superfund site in the 1980s, rotary kiln incineration was the only fully demonstrated, commercially available and permitted technology for cleaning up dioxin in soil. Since then, additional remediation technologies for the cleanup of dioxin-contaminated soil and sediments have been researched and developed, but several of the accepted techniques still rely on thermal destruction, which is energy intensive. Heat-based destruction techniques for treating dioxin-contaminated soil and debris include incineration, thermal desorption, and vitrification. Incineration at temperatures above 1200°C is considered the most effective way of destroying dioxins. Thermal desorption, which operates at lower temperature range to vaporize dioxins, is also commonly used. A large-scale cleanup was completed in 2018 at the Bien Hoa Airport in Danang, Vietnam where nearly 95,000 m3 were excavated and treated with thermal desorption (USAID, 2018). Vitrification is largely a stabilization technique that uses very high temperatures to melt contaminated soil. When subsequently cooled, it forms a glassy mass that traps contaminants and reduces their mobility.

 (Research and bench-scale studies are documented in the resources below.) However, their applicability and effectiveness in the field is being assessed. The application of activated carbon to contaminated soil and sediment also shows promise for mitigating the bioavailability of dioxins and reducing entry into the food chain. Additional thermal and non-thermal technologies that have been researched and tested include base-catalyzed decomposition, photodegradation with ultraviolet light, supercritical water oxidation, and others. CLU-IN | Contaminants > Dioxins
