Subcritical Hydrothermal Blasting Technology
By high reactivity of subcritical water and destruction effect of crystal by blasting, this technology realizes high purification performance.
The Summary
■Decontamination of radioactive materials and contaminated materials
【Achievements】Participated in a decontamination verification testing project in Fukushima / Executed verification tests by a demo plant
【Patents】 Patents acquired in China, U.S., Russia and Japan
【Application of the technology】
・Purification of farm lands contaminated by heavy metals such as cadmium
・Treatment of arsenic containing soil occurred at construction works of highways and railways, etc.
・Increase of added value of biomass residue or transformation of the residue to energy (solid fuel, etc.)
