Abstract
The invention relates to a method for rendering waste sorbent material recyclable. The method includes collecting polymer-based sorbent materials containing one or more solvents, treating the waste material in a centrifugal treatment system for removing the solvents from the polymer-based sorbent materials whereby the sorbent materials have a residual solvent content that renders the materials non-hazardous for transportation to a remote recycling site. The treatment system includes a fume collection system and a centrifuge disposed in the fume collection system. The sorbent materials are charged into the centrifuge and the centrifuge is operated for extractive removal of solvents therefrom and collection of the extracted solvents. The sorbent materials are rendered non-hazardous by the centrifugal treatment system enabling the materials to be taken off site for use in making recycled parts.
