The major selling points for composite lumber are that it is free of potentially hazardous chemicals, and made largely from long-lasting, low-maintenance, recycled materials. It is, thus, often promoted as an environmentally preferable or “green” alternative to other decking materials. In this paper we examine the performance of wood-plastic composite (WPC) decking and its environmental properties. We also highlight a recently completed life cycle analysis (LCA) and comparison of WPC decking and western red cedar decking. The recent third-party LCA study considered a number of environmental performance measures.
Wood-plastic composite (WPC) lumber is made primarily from high-density polyethylene (HDPE), recovered from the waste stream mainly in the form of used milk containers or recovered plastic bags, and from wood wastes (often planer shavings) that have been ground to a fine powder. A 50:50 mixture of plastic and wood is common. A few WPC products make use of low-density polyethylene, polypropylene, or polystyrene plastics and various materials other than wood, including agricultural fibers and fiberglass. While use of a high percentage of recovered plastic is common (100 percent is not unusual), some brands contain markedly less recycled plastic content and little to no post-consumer plastic content.

In addition to decking and fencing, plastic composite materials are being used today in making a wide variety of products including automotive parts, pallets, playground equipment, picnic tables, park benches and chairs, landscape timbers, railroad ties, and docks. Auto interiors and decking for outdoor applications represent the largest market for woodplastic composites in both Europe and North America. Growth is most rapid, in both regions, in the decking segment. Plastic composite decking currently accounts for 10 percent of the residential decking market in North America and 6 percent in Europe. In the U.S., use of plastic composite materials for residential decking is projected to reach 23 and 32 percent of the total decking market by 2011 and 2016, respectively (Wood 2007). Solid wood remains the primary decking material globally.
