Process and device for separation and recovery of waste carpet components

A process for separation and recovery of waste carpet components, wherein waste carpets comprise a face fiber material, a backing material and an adhesive coating which includes latex and filler, said process comprising:

• shredding of waste carpets in a shredding machine, the shredding producing a shredded waste carpets;
• washing of the shredded waste carpets that have been shredded in the shredding with a liquid washing agent in a high friction washer without reducing a size of the shredded waste carpets, wherein due to the action of high friction forces and the liquid washing agent, at least some of the adhesive coating is decoupled from the face fiber material and backing material;
• removing at least some of the adhesive coating from the high friction washer during washing through a washing sieve within the high friction washer, the removing producing a first remaining material;
• fine wet grinding of the first remaining material obtained from the washing in a wet granulator to reduce the size of the face fiber material and the backing material, the fine wet grinding producing a second remaining material;
• and
• separating the second remaining material obtained in the fine wet grinding in a centrifuge into face fiber and backing material.
