METHODS FOR REDUCING CONTAMINATION IN PLASTICS RECOVERED FROM DURABLE GOODS

A process for reducing the content of residual organic substances in mixtures of plastics from durable goods can include separating a feed stream into two or more mixtures of flakes and preforming a cleaning process to remove a portion of one or more of the absorbed organic substances from one or mo...

Zusammenfassung:	A process for reducing the content of residual organic substances in mixtures of plastics from durable goods can include separating a feed stream into two or more mixtures of flakes and preforming a cleaning process to remove a portion of one or more of the absorbed organic substances from one or more of the mixtures. Each mixture can contain one or more plastic types and at least one organic substance absorbed into the one or more plastic types. The flakes in the mixtures can have an average particle diameter of less than 10 millimeters.
