Description

[0001] This application claims the benefit of U.S. Provisional Application No. 61 / 696,476, filed Sep. 4, 2012, which is hereby incorporated by reference in its entirety.BACKGROUND AND SUMMARY OF THE INVENTION

[0002] Exemplary embodiments of the present invention relate generally to composite products and related methods for manufacturing such products. Composite materials can offer many benefits as compared to natural materials such as wood. However, despite many years of development, there is still a need to improve the formulation, manufacturing, and resulting characteristics of composite materials.

[0003] Many composite products are made from virgin materials. However, virgin materials may be in limited supply and / or costly. Thus, there is a need to use at least a portion of recycled material in the formulation of a composite. There is also a need to use at least a portion of recycled material for sustainability reasons and also to potentially earn LEED points.

[0004] There is also a ne...
