First claim
Opening claim text (preview).
What is claimed is: 1. An extruded polymer composition consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has about 25% by weight to about 100% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or a homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate. 2. The extruded polymer composition of claim 1 , wherein the polyethylene terephthalate polymer composition has at least about 50% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 3. The extruded polymer composition of claim 1 , wherein the polyethylene terephthalate polymer composition has at least about 75% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 4. A polymer mixture consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has about 25% by weight to about 100% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or a homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate. 5. The polymer mixture of claim 4 , wherein the polyethylene terephthalate polymer composition has at least about 50% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 6. The polymer mixture of claim 4 , wherein the polyethylene terephthalate polymer composition has at least about 75% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 7. A carpet comprising a fiber comprising an extruded polymer composition consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has about 25% by weight to about 100% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or a homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate. 8. An extruded polymer composition consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has about 50% by weight to about 100% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or a homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate. 9. The extruded polymer composition of claim 8 , wherein the polyethylene terephthalate polymer composition has at least about 75% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 10. The extruded polymer composition of claim 8 , wherein the polyethylene terephthalate polymer composition has at least about 90% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate. 11. A polymer mixture consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has about 50% by weight to about 100% by weight of homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or a homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized deposit post-consumer polyethylene terephthalate, or homogenized deposit post-industrial polyethylene terephthalate, or the homogenized blend of deposit post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate. 12.
