REMEDIATION OF PCB SOIL CONTAMINATION BY ON-SITE INCINERATION

Throughout the world, sites have been discovered which contain hazardous wastes. To completely destroy the contaminants in the soil, incineration remains the primary option for soils containing organics with high boiling points. This paper deals with operational aspects of the Transportable Incineration System, including specific procedures which were developed during the incineration of PCB-contaminated soils at the Lauder salvage yard in Beardstown, Illinois. Some of the issues treated in this paper include: • • Prescreening of soil to remove oversize materials. • • Process description. • • Treated soil material handling at elevated temperatures. • • Slag formation in the kiln and secondary combustion chamber. • • Development of procedures required for trial burn testing. Some of these procedures may require special system design consideration. © 1990.
