1. A composite building product comprising: a continuous polymeric skin comprising melted particulate waste materials that comprise melted particulate reclaimed carpet waste materials and melted particulate mixed plastic waste materials, wherein the continuous polymeric skin defines an interior cavity; anda foamed core positioned within the interior cavity that is surrounded by and completely encased by the skin,wherein the melted particulate reclaimed carpet waste materials comprise a thermoplastic fibrous polymer, a carpet backing material, and an adhesive, wherein the melted particulate mixed plastic waste materials comprise at least one polymeric material selected from the group consisting of recycled container materials and recycled plastic bottle waste materials, and wherein the melted particulate reclaimed carpet waste materials comprise between about 30 to 70 percent by weight of the melted particulate waste materials and the melted particulate mixed plastic waste materials comprise between about 30 to 70 percent by weight of the melted particulate waste materials. 2. The composite building product of claim 1, wherein the recycled container materials comprise at least one polymeric material selected from the group consisting of high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), and polyethylene terephthalate (PET). 3. The composite building product of claim 1, wherein the recycled plastic bottle waste materials comprise at least one polymeric material selected from the group consisting of high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), and polyethylene terephthalate (PET). 4. The composite building product of claim 1, wherein the skin further comprises at least one additive and virgin polymer materials. 5. The composite building product of claim 4, wherein the virgin polymer materials of the skin comprise at least one polymeric material selected from the group consisting of high density polyethylene (HDPE), low density polyethylene (EDIT), polypropylene (PP), and polyethylene terephthalate (PET). 6. The composite building product of claim 4, wherein the at least one additive of the skin is selected from the group consisting of UV stabilizers, flame retardants (FR), antifungals (AF), polymeric compatibilizor, colorants/dyes, and anti odor materials. 7. The composite building product of claim 1, wherein the melted particulate reclaimed carpet waste materials further comprise at least one type of impurity, and wherein at least one of the at least one type of impurity is selected from the group consisting of dirt, sand, oil and inorganic filler. 8. The composite building product of claim 4, wherein the skin comprises between 1-15% additives. 9. The composite building product of claim 1, wherein the skin further comprises thermoset materials. 10. The composite building product of claim 1, further comprising at least one wear layer coupled to a top surface of the skin. 11. The composite building product of claim 1, further comprising at least one base layer coupled to a bottom surface of the skin. 12. The composite building product of claim 1, further comprising at least one structural layer disposed therein the foamed core. 13. The composite building product of claim 12, wherein the at least one structural layer is selected from the group consisting of: fibrous pads, woven fabrics, non-woven fabrics, post consumer carpet pieces, metal reinforcing members, pipes, wood boards or strips, metal fencing, and bubble wrapping. 14. The composite building product of claim 1, wherein the foamed core further comprises at least one additive, and wherein the at least one additive is selected from the group consisting of UV stabilizers, flame retardants (FR), antifungals (AF), polymeric compatibilizor, colorants/dyes, and anti odor materials. 15. The composite building product of claim 1, wherein the foamed core comprises between 1-99% post consumer carpet material. 16. The composite building product of claim 1, wherein the foamed core comprises between 1-80% particulate mixed waste material. 17. The composite building product of claim 1, wherein the foamed core comprises between 1-10% chemical blowing agents. 18. The composite building product of claim 1, wherein the foamed core comprises between 1-5% chemical blowing agents. 19. The composite building product of claim 14, wherein the foamed core further comprises natural or manmade fibers. 20. The composite building product of claim 1, wherein the melted particulate reclaimed carpet waste materials further comprise at least one filler. 21. A composite building product comprising: a continuous polymeric skin comprising melted particulate waste materials that comprise melted particulate reclaimed carpet waste materials and melted particulate mixed plastic waste materials, wherein the continuous polymeric skin defines an interior cavity; anda foamed core positioned within the interior cavity that is surrounded by and completely encased by the skin,wherein the melted particulate reclaimed carpet waste materials comprise at least one type of impurity selected from the group consisting of dirt, sand, oil, and inorganic filler, wherein the melted particulate mixed plastic waste materials comprise at least one polymeric material selected from the group consisting of recycled container materials and recycled plastic bottle waste materials, and wherein the melted particulate reclaimed carpet waste materials comprise between about 30 to 70 percent by weight of the melted particulate waste materials and the melted particulate mixed plastic waste materials comprise between about 30 to 70 percent by weight of the melted particulate waste materials. 22. The composite building product of claim 21, wherein the melted particulate reclaimed carpet waste materials further comprise a thermoplastic fibrous polymer. 23. The composite building product of claim 21, wherein the melted particulate reclaimed carpet waste materials further comprise a carpet backing material. 24. The composite building product of claim 21, wherein the melted particulate reclaimed carpet waste materials further comprise an adhesive.
