<p>A system and method for reclaiming backing material from waste carpet or other products includes a chopper (110) capable of handling large pieces of waste carpet, at least two grinding or granulation steps (114, 124) to reduce the size of the waste carpet pieces and to dislodge carpet fibers from the remaining material, and at least three separation steps (116, 126, 138) to remove the dislodged fibers; one of the separation steps involves vibratory screening. Backing material reclaimed in this manner has a relatively low contamination level, and is suitable for reuse as carpet backing with little need for the addition of virgin backing material. The system and method further provide for the extrusion of the reclaimed backing material for use as new carpet backing.</p> |
