An extruded polymer composition consisting essentially of a polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has from greater than 0% up to about 100% by weight of homogenized curbside post-consumer polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or a homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized curbside polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or the homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate.
A polymer mixture consisting essentially of a polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has from greater than 0% up to about 100% by weight of homogenized curbside post-consumer polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or a homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized curbside polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or the homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate.
A carpet comprising a fiber consisting essentially of polyethylene terephthalate polymer composition, wherein the polyethylene terephthalate polymer composition has from greater than 0% up to about 100% by weight of homogenized curbside post-consumer polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or a homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate, and balance virgin polyethylene terephthalate, wherein the homogenized curbside polyethylene terephthalate, or homogenized curbside post-industrial polyethylene terephthalate, or the homogenized blend of curbside post-consumer and post-industrial polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate.
