The paper will describe a new generation of innovative structural products made from 100% recycled consumer and industrial plastics called Thermoplastic timber. Developed by scientists at Rutgers University and tested by the US Army Corps of Engineers, the patented technologies provide products that are extremely strong and durable, flexible in design, and virtually maintenance-free. Successful demonstrations have shown that Thermoplastic timber is a viable alternative to more traditional building materials including wood, steel, and concrete. Initial applications for these materials include bridges, railroad ties, pilings, marinas, boardwalks, and retaining walls. Thermoplastic timbers are an ideal replacement for any application requiring treated lumber.
