This technology preserves the water environment preventing the diffusion of H.H.Ms eluted from the soil contaminated with them into groundwater or surface water physically and scientifically by mixing MgOSM and contaminated soil.

This technology reuses the soil by mechanically washing and classifying the excavated contaminated soil to separate and remove contaminants (heavy metals, oil, agrichemicals, etc.)

This technology improves the ground environment by supplying nutrients and oxygen to soil and groundwater contaminated with volatile organic compounds such as tetrachlorethylene and oil, and detoxifying hazardous substances contained in soil and groundwater by the power of microorganisms.

This technology volatilizes and separates PCBs, dioxins and/or agrichemicals in the soil, and decomposes them in a steam separating system. The treatment from leaching to decomposition of the contaminants is performed in a sealed state.

This technology can effectively utilize resources by sorting wastes which are dumped illegally or generated by the disaster of a huge earthquake or heavy rain into soils and wastes by type and recycling.

To purify Water by dredging the bottom sludge of eutrophic lakes and marshes. Then the dredged sludge, with dehydration and solidification, be effectively utilized for resources of embankments, etc.

Ultra Fine Bubble　(hereinafter referred to as “UFB”) can improve lake environment that is in oxygen-deficient condition due to decrease of dissolved oxygen (DO). This technology can purify water quality and bottom sediment, and preserve the water environment.
