ABSTRACT:
A system and method for remediation of contaminated soil are provided. The system comprises a soil remediation cell of contaminated soil and a plurality of multi-functional conduits located within the contaminated soil. Each multi-functional conduit defines a reaction housing. The multi-functional conduits includes heating elements for introducing heat into the contaminated soil for volatilizing the contaminants located within the contaminated soil, without utilizing mechanically driven forced air. This produces a contaminated vapor. The system and allows for re-circulation of vapors generated during breakdown of contaminants allowing for use of the re-circulated vapor for heat production and energy use. The system may be utilized for remote access and portability to disparate locations whereby the system does not require use of a container or receptacle. A substantial portion of the contaminants in the contaminated vapor are destroyed in the reaction housing. A substantially non-contaminated vapor is produced in which at least about 80% by weight of the contaminants have been destroyed.
