Assessment of International Technologies for Superfund Applications: Technology Review and Trip Report Results

摘要

Several international technologies were identified and investigated for their applicability to hazardous waste site remediation in the United States. The field team visited with twelve research groups, consultants and manufacturers at 15 locations in The Netherlands, Belgium and the Federal Republic of Germany (FRG). Results of the individual site visits are summarized and a capsule summary of each technology includes a brief process description, discussion of process limitations, performance data, costs, and status of process development. Identified were site cleanup technologies not currently used in the U.S., as well as unique applications of techniques used in the U.S. Among the most important findings were five different soil washing techniques in Holland and the the FRG. Another key finding was the High Temperature Slagging Incinerator technology reviewed in Belgium. In addition, the field team reviewed unique applications of in situ biological treatment and composting techniques, vacuum extraction and in situ air stripping, in situ extraction of cadmium from soils, application of rotating biological contractors, and electrochemical dehalogenation techniques.
