Over 2 million tons of post-consumer carpet is landfilled each year. This waste carpet is a potential resource for composites. This paper focuses on the processing and properties of nylon 6 post-consumer carpet. The carpet is cleaned, shredded and extrusion pelletized. This feedstock is compounded with glass fibers and compatibilizers. Based on the properties achieved and the projected costs, applications are identified.
