Plastic lumber - Wikipedia

plastic lumber (PL) is a plastic form of lumber (timber) made of virgin or recycled plastic It is made of 100% plastic, compared with wood-plastic composite lumber. Widely employed in outdoor decking, it is also used for molding and trim and garden furniture such as park benches. Unlike wood-plastic composite lumber, plastic lumber is 100% recyclable after its original intended use. Resin, regrind, and most of the additives are combined and processed in a pelletizing extruder.
