Abstract
The present invention provides a system for thermal remediation and/or the processing of a feed materials like contaminated materials, waste polymeric materials, waste paper products, waste wood and biomass. The system comprises at least one thermal screw conveyor provided in a housing under pressure, a first plug screw conveyor in a housing in communication with an inlet of thermal screw conveyor housing and a second plug screw conveyor in a housing in communication with an outlet of thermal screw conveyor housing. The thermal housing is configured to heat the feed material to form one or more vaporized products and a solid residue, wherein one or more vaporized products are removed through the one or more vapor ports provided in the pressure housing, and the solid residue is discharged from an outlet of the second seal-housing.
