Method for the separation of overlapping density porous materials from less porous materials
Abstract
Enhanced methods for separating of overlapping density porous materials are provided. The methods of the invention exploit the differences in the porosity of porous feed materials compared to that of the solid plastics. In the first stage, air is forced out of the pores of a porous feed material. In the second stage, a solution, having the appropriate density, is forced into the pores. This increases the density of the porous material relative to the density of the solid plastics. As a result, the porous material can be made to sink, while the solid plastics continue to float.
