A carpet waste composite and method for making the same are disclosed. In one embodiment of the method, cleaned, unadulterated layers of carpet having a backing side and a tufted side are provided. An initial, unfused carpet layer is made by placing two cleaned, unadulterated layers of carpet tufted side-to-tufted side with homogenous and adhesive contact therebetween. Heat and pressure followed by cooling are applied to furnish an initial, fused carpet layer. An iterative, unfused carpet layer is created by placing two cleaned, unadulterated layers of carpet tufted side-to-tufted side with the initial, fused carpet layer interposed therebetween using adhesive contact. Heat and pressure followed by cooling are applied to furnish an iterative, fused carpet layer. The process of adding layers may continue as required.
