Geo-Steam TechnologyTM
Technology / Service Summary
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.
Purpose
                                            Detoxifying hazardous substance with thermal desorption method 
which is available to volatilize and separate persistent substance such as PCBs, dioxins and/or agrichemicals
                                        
Feature
                                            a) Available to stable temperature control by thermal desorption method
b) All steps of the treatment are performed in a sealed state, and no condensed contaminants are handled
c) Available to detoxify decomposed steam by passing it through a gas treatment facility
d) Available to treat on-site
e) Certified by Japanese government
                                        
Effect
                                            a) Available to improve recycle rate with high sorting accuracy by the sort flow depending on buried wastes
b) If a polymer-based modifier is used, not only the sorting accuracy can be improved, but also the dust generated during sorting can be reduced
