All contaminants that could disturb the preparation process are removed during the examination for impurities. This is followed by grinding, in some cases multi-stage, to make regrinds and
several washing, cleaning and separation processes. Subsequently, the clean regrinds are mechanically dried.
Even now the resulting product can already be processed in the plastics industry as a substitute for virgin plastics.
