Abstract
A method for reformulating reclaimed, contaminated mixed waste plastics into useful articles wherein a plurality of batches of the mixed waste plastics are preprocessed to produce substantially homogeneous mixtures of a desired particle size range that are characterized according to their respective apparent densities, and are thereafter blended to produce a mixed plastic feed material having a rheology predetermined to be desirable for reprocessing into at least one of such useful articles.
