Abstract: A construction article comprising recycled plastic (e.g., polyethylene terephthalate) is provided. The plastic is preferably derived from post-consumer waste such as food or beverage containers. An adhesive network is created using an adhesive suitable for the chosen plastic(s), and pieces of the plastic are interspersed among that adhesive network in the final construction article. The construction articles are high strength, flame resistant, and water resistant and can be in the form of a sheathing panel, dimensional lumber, or other desired shape.
