※EcoCycle is a recognized and certified Site Investigation agency by Ministry of Environment (Reg. No. 2014-3-17）
●EcoCycle believes detailed site investigation is very important for successful site remediation●
Why detailed site investigation is required？
Detailed site investigation gives in depth knowledge on contmination and site hydrogeology. This helps develop the best remedial designs and read total cost and time of remediation with great accuracy.

Bioremediation of Chlorinated compounds
Bioremediation（Biostimulation）
Bioremediation is an environmental friendly remedial technology where indigenous microbes are
stimulated by injecting propriatory nutrients such as EDC/EDC-E. These microbes degrade the toxic
compounds into harmless water and carbon dioxide. The biostimulants are made of food-grade ingredients
and environmentally safe as they are completely biodegradable.

Merits
EDC is soluble in water and it propagates easily along the target volume upon injection into the subsurface.
In addition, nutrients are easily consumed by microbes resulting quick formation of anaerobic conditions in
subsurface and stimulating effective microorganisms.
Upon injection of EDC, the sorbed mass of DNAPL is dissolved into the groundwater and thereby available for biodegradation. A fine combination of nutrients also stimulates a wide range of microbial consortium capable of degrading contamination of high concentration.
EDC is safe as it is made from food materials.It is biodegradable and therefore will not remain in the
subsurface after total cleanup of the site
The cost of bioremediation is <1/3 of traditional methods such as dig and dispose
Remedial measure is possible under the factories in operation or under the buildings.
ElutionElution
Bioflushing
Chemical Oxidation
Other Remedial Techniques
VOCs are degraded by an application of Oxidant（Per sulfates, peroxides, etc.). Oxidation is a preferred medhod to treat high concentration contaminants with short time remedial goal.
Bioflushing is an appropriate quick remedial measure targeting high concentrated/complex contaminants adsorbed to subsurface soil. Injection of bioflushing solvents dissolves the sorbed mass which can be pumped up and treated on site. The remaining contamination would be treated with bioremediation until the concentration drops below environmental standard.

Hydrocarbons, and Cyanide Compounds.
Oxidants (Hydrogen Peroxide or Sodium Persulfate, etc.) are mixed or injected into the overburden soil/groundwater
to degrade target contaminants.
Soil contaminated with petroleum hydrocarbon is mixed with GeenClean-X and bio-pile is created. Areobic condition is created by
sucking air into the pile. The process stimulates native aerobic microflora and the temperature of the pile rises steadily.
Once the temperature corsses 50 degrees centrigrade, thermophiles kick into action to degrade target compounds.
Appropriate Site・BTEX (benzene, etc.),Fuel Oils（Gasoline, Kerosene,
Diesel, Heavy oil), PAHs, VOCs, etc. contaminants
・Contamination found in unsaturated zone and clay/silty soil
・Higher contaminant concentrations
・Site accessible for excavation and on site treatment
Appropriate Site・Conatminants that are difficult to insoluble in water/difficult to degrade microbiologically.
・Effective for Ferrocyanide/Ferricyanides, Dioxins, PCBs etc.
Appropriate Site・Light Oils
・Low to moderate contaminant concentration
・Both saturated and unsaturated zones
・Mixture of contaminants, VOCs and Oils
・Short time remedial targets

Site Remdiation by Chemical Oxidation
EcoThermo Flush
Cyanides (ferri and ferro cyanides) are produced during coal gasification. They are almost insoluble in water and persistent contaminants. Bioflushing is applied to remediate such sites. In this process metal-cyanide dissolving substances are injected subsurface to mobilize the sorbed/insoluble mass followed by pumping and treating the dissoved phase. At subsequent phase bioremediation is used to degrade trace remaining contamination.

depend on the site conditions and type of metals
and concentration of metal contaminants.
Heavy Metal Stabilizing Agent NanoLite Earth
NanoLite Earth is a material that adsorbs ionized and soluble heavy metals in soil making it insoluble in soil-water system
preventing the elution of heavy metals shaping into the groundwater. It is applicable for all types of metals with high
adsorption rates. This material is made from natural minerals. Unlike mixing cement based stabilizing agent, NanoLite does
not impact natural soil properties.
Heavy Metal Contamination
Soil Heavy Metal Stabilization Technology
●Adsorption by Layered Double Hydroxide●Adsorption by Clay Minerals
Hydroxide ions in clay minerals adsorb most of the heavy metals stabilizing soil.
●Adsorption by Natural Minerals
Heavy metals such as Lead, Cadmium, etc. are adsorbed to negative ions of natural minerals.
