Since that time, recycled plastic lumber (RPL) products have proven to be effective alternatives for many applications, offering high durability and requiring little maintenance. Plastic lumber products are resilient, weather-resistant, and impervious to rot, mildew, and termites. They do not require painting or staining. While RPL is widely employed in the construction of outdoor decks, plastic lumber is also being used to fabricate moldings, doorjambs, window casings, playground equipment, railway ties, pilings, posts and fencing products. 
The development and commercialization of new high-throughput, low-cost processing technologies will afford the opportunity to further close the recycling loop for the PE film and other plastics collected in industrial, commercial and municipal programs This report details the properties and application of RPL and composite door panels, charts the growth in the plastic lumber industry, describes the capabilities of the various production processes and additives, and profiles the major players. It also addresses the need for product standards and building code amendments
to support the future growth of markets for plastic lumber.
Finally, the report describes a series of three hypothetical processing facilities: a line manufacturing woodfibre composite deck boards from recycled PE film, one manufacturing pure polymer plastic deck boards from recycled HDPE milk jugs, and a new flow mold system designed to produce large dimension plastic timber products from a variety of mixed and contaminated plastics. The report provides a comparative analysis of the three commercially-available production processes, in terms of their wpc garage door  cost, operation, and capacity to utilize recycled plastic feedstocks.
