1. A composite building material comprising: a carpet waste;an inorganic filler in addition to any filler present within the carpet waste and any synthetic fiber filler; anda binding agent in intimate association with the carpet waste and the inorganic filler. 2. The composite building material of claim 1, wherein the carpet waste comprises melted polypropylene fibers and unmelted polyester fibers. 3. The composite building material of claim 1, wherein the carpet waste comprises face fibers consisting essentially of a material selected from the group consisting of polyester, nylon, and polypropylene. 4. The composite building material of claim 1, further comprising a natural fiber filler. 5. The composite building material of claim 1, further comprising an exposed patterned surface on at least a portion thereof, the exposed patterned surface comprising at least one of an embossed surface and a colored surface. 6. The composite building material of claim 1, further comprising a coating, the coating comprising a material selected from the group consisting of a primer, a paint, and a stain. 7. A method of producing a composite building material, the method comprising the steps of: providing a carpet waste;providing an inorganic filler, wherein the inorganic filler is in addition to any filler present within the carpet waste and any synthetic fiber filler;mixing the carpet waste and the inorganic filler with a binding agent to produce a carpet waste mixture; andheating and pressing the carpet waste mixture to form the composite building material. 8. The method of claim 7, wherein the carpet waste comprises unmelted polyester fibers and melted polypropylene fibers. 9. The method of claim 7, wherein the carpet waste comprises face fibers consisting essentially of a material selected from the group consisting of polyester, nylon, and polypropylene. 10. The method of claim 7, further comprising adding a natural fiber filler. 11. The method of claim 7, further comprising forming a patterned surface on at least a portion of the composite building material, the patterned surface comprising at least one of an embossed surface and a colored surface. 12. The method of claim 7, further comprising applying a coating, the coating comprising a material selected from the group consisting of a primer, a paint, and a stain. 13. The method of claim 7, further comprising actively cooling the composite building material under pressure. 14. The method of claim 7, further comprising modifying a cross-sectional profile of the composite building material using at least one of thermoforming, embossing, and cutting. 15. A composite building material comprising: a sheet having a first exterior surface and a second exterior surface defining a thickness, the sheet comprising a substantially homogeneous mixture from the first surface across the thickness to the second surface, the sheet comprising: a carpet waste; anda binding agent in intimate association with the carpet waste,wherein at least one of the first exterior surface and the second exterior surface comprises at least one surface feature selected from the group consisting of a molded patterned surface, an embossed patterned surface, and a hot-stamped layer. 16. The composite building material of claim 15, wherein the carpet waste comprises melted polypropylene fibers and unmelted polyester fibers. 17. The composite building material of claim 15, wherein the carpet waste comprises face fibers consisting essentially of a material selected from the group consisting of polyester, nylon, and polypropylene. 18. The composite building material of claim 15, further comprising a natural fiber filler. 19. A method of producing a composite building material, the method comprising: providing a carpet waste;mixing the carpet waste with a binding agent to produce a carpet waste mixture; andheating and pressing the carpet waste mixture to form the composite building material comprising a sheet having a first exterior surface and a second exterior surface defining a thickness, the sheet comprising a substantially homogeneous mixture from the first surface across the thickness to the second surface,wherein at least one of the first exterior surface and the second exterior surface comprises at least one surface feature selected from the group consisting of a molded patterned surface, an embossed patterned surface, and a hot-stamped layer. 20. The method of claim 19, wherein the carpet waste comprises unmelted polyester fibers and melted polypropylene fibers. 21. The method of claim 19, wherein the carpet waste comprises face fibers consisting essentially of a material selected from the group consisting of polyester, nylon, and polypropylene. 22. The method of claim 19, further comprising adding a natural fiber filler. 23. The method of claim 19, further comprising modifying a cross-sectional profile of the composite building material using at least one of thermoforming, embossing, and cutting. 24. The composite building material of claim 1, further comprising synthetic fiber filler in intimate association with the binding agent. 25. The method of claim 7, further comprising adding synthetic fiber filler to the carpet waste mixture. 26. The composite building material of claim 1, characterized by an absence of synthetic fiber filler. 27. The method of claim 7, wherein the composite building material is characterized by an absence of synthetic fiber filler. 28. The composite building material of claim 15, further comprising a surface feature selected from the group consisting of a foil laminate, a film laminate, a sanded surface, a primer, a paint, and a stain. 29. The method of claim 19, wherein the composite building material further comprises a surface treatment selected from the group consisting of a foil laminate, a film laminate, a sanded surface, a primer, a paint, and a stain.
