Recycled Plastic Lumber: From Park Benches to Bridges
The first applications of plastic lumber products were in non-structural applications such as picnic tables and benches. As the industry has matured through the years, innovative research and development work by the plastic lumber industry and universities has fostered the development of superior performing products which in turn has begun to establish new and demanding structural applications for these products. Much of the work has involved the application of composites technology to the reuse of post-consumer and post-industrial materials in plastic lumber products. This evolution, from non-structural applications through the development of structural materials and their application will be discussed.
