Introduction

Biodegradation of tetrachloro dibenzo-p-dioxin (TCDD) has been reported in the scientific literature, in the laboratory, and in pilot studies. From 1999 to 2009, Vietnamese researchers conducted several studies to detoxify heavily contaminated soil in the former Da Nang military base1

. 

Full-scale bioremediation of 3,384 m3 of dioxin contaminated soil was demonstrated in Bien Hoa, Vietnam, in 2009. Several international scientific work groups have concluded that bioremediation is the most environmentally responsible and cost-effective remedy for cleaning up Agent Orange residues at the former air bases in Vietnam.

More than 30 years after the US-Vietnam War, spilled Agent Orange defoliant solution containing traces of the dioxins, TCDD and octachloro dibenzo-p-dioxin (OCDD), 2,4,5-T, 2,4-D, and chlorophenols (TCP and DCP) remains in the soil and in lake sediment affected by contaminated soil, which had been carried by runoff from the former military airbase in Da Nang2 . Natural attenuation of the herbicides and dioxins has not been effective in detoxifying the soil or sediment. 

This first joint study by Vietnamese and American researchers was conducted to

demonstrate whether the soil in Da Nang can be bioremediated effectively using aerobic or anaerobic microbial processes. This study also sought to provide engineering design guidance to support the selection of either an aerobic or an anaerobic amendment recipe and an operating strategy to optimize biological treatment. 

Conclusions Aerobic bioremediation is capable of significantly reducing TCDD toxicity (p=0.0026). Bioaugmentation with small amounts of treated soil or contaminated sediment may be effective for anaerobic treatment. However, if suitable growth conditions are provided, the indigenous microbes in the mixed soil and sediment at Da Nang appear capable of degrading TCDD without adding another source of microbes. Anaerobic bioremediation rate is about half the rate of aerobic treatment, but the results are not as significant (p=0.25). From our of point active landfill containing both aerobic and anaerobic degradation become feasible resolution for detoxification of heavy herbicide/dioxin in full scale in Vietnam. 

Bioremediation is recognized as a “Green Technology,” which has a very low energy requirement and produces few emissions. Bioremediation is a permanent solution which produces a soil which can be returned to beneficial use. Knowledge gained from this project by both Vietnamese and US scientists will allow for design of customized recipes suitable for addressing dioxin and other persistent organic pollution problems throughout Vietnam and elsewhere

This type of Incinerator is very similar to the #Downdraft #Gasifer Offgrid Hot Water and Hot Air system I designed and shared months ago. https://t.co/Im01RKt8uo pic.twitter.com/jGsSxS4aor

Remediation Terminology Definitions

Frequently used Soil and Water definitions ElectroHemp uses  when sharing the BioRad system and process which organically cleans Water and Soil in the Phyto-Enhanced system.

Phytoremediation is defined by UNEP as the living green plants for in sutu removal, degradtion, and containment in soils, surface waters, and groundwater.

Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminates in the soil and other environments.

Contamination is defined as any impairment of the quality of the water of the State by sewage or industrial waste to a degree which creates an actual hazard to public health thru poisoning or through the spread of infectious disease.

Heavy Metals are defined as the metals that have an atomic mass greater than 20 and are transition metals, metalloids, actinides, and lanthanides.

Toxicity is the ability of a substance to cause a living organism to undergo adverse effects upon exposure.

Phytoremediation EPA Field Research

Phytoremediation and prior EPA Field demonstrated projects to remediate heavy metals proves Bioremediation is a viable and cost saving option for Radianuclides removal.
The EPA has previously listed about 194 ongoing Phytoremediation / bioremediation field research projects. Yr 2000

194 ongoing phytoremediation field research projects, EPA 

Heavy metals and radionuclides represent about 30% of this activity supporting that bioremediation is a feasible technology to decontaminate the environment. 

Unlike many organic contaminants most:

•  metals and radionuclides cannot be eliminated from the environment by chemical or biological transformation. 
• Although it may be possible to reduce the toxicity of certain metals by influencing their speciation, 
• they do not degrade and are persistent in the environment. 

The conventional remediation technologies that are used to clean heavy metal polluted environments are:

• soil in situ vitrification
• soil incineration
• excavation and landfill
• soil washing
• soil flushing
• solidification
• stabilization with electrokinetic systems

ElectroHemp is entering: Innovating Soil 3.0 Contest

It's official, ElectroHemp has entered the FoodShot Global  contest! 

Announcement middle January

ElectroHemp has entered the FoodShot Global  contest! 

Have you heard about the 2018-2019 FoodShot Global event that will be promoting soil health to increase food safety? 

ElectroHemp will be entering the process and system that organically cleans soil and water, better known as green remediation in the FoodShot’s first annual challenge — Innovating Soil 3.0. 

ElectroHemp will be competing and in the running for up to $10 million in equity funding and $20 million in debt funding!!!

Rajiv Singh, co-chairman of FoodShot Global, wrote on Agfunder about the contest: a search for projects and ideas that utilize the latest in technology, science, and engineering to address the crisis of soil deterioration. In particular, he writes about how a diverse set of technologies can be brought to bear to improve the conditions of the world’s soils, from machinery and equipment to low-tech farming practices, to carbon sequestration tools.
