MOLDABLE POLYMER MATERIAL CONTAINING RECYCLED AUTOMOTIVE SHREDDER RESIDUE (ASR) AND METHOD OF MANUFACTURE
Moldable material comprising at least 5% by weight of polymeric regrind material recovered from Automotive Shredder Residue (ASR) and method of manufacturing the same are provided. The method comprises the steps of providing a polymer material sorted from ASR; grinding the polymer material sorted from ASR to form a regrind material; depositing the regrind material into a liquid solution having a specific gravity and performing a liquid density separation; removing a plurality of pieces of regrind material having a specific gravity of less than the liquid solution specific gravity from a surface of the liquid; conditioning the removed pieces of regrind material; blending the respective pieces of regrind material with a primary polymer to create a polymeric blend; compounding the polymeric blend via the addition of at least one additive thereby creating a plastics compound; and supplying the resultant plastics compound to an extrusion machine to produce the moldable material.
