We have newly developed contaminated soil remediation systems using indirect heated kiln and direct heated kiln which were originally developed for industrial waste treatment. The type of the kiln is decided due to the kind of contaminants. The former is applicable for the remediation of VOC or metals with low melting point. The latter is for metals with high melting point. Using the existing kilns, several remediation tests have been conducted and good results have been obtained for the soils contaminated with oil, VOC and heavy metals. We will continue to study for the practical application of these systems and the construction of the first utilizing plant with large capacity.
