Fiber reinforced polymer (FRP) composite products offer many significant environmental benefits such as light weight, superior mechanical properties, extended service life, low maintenance and resistance to corrosion. But until now it has been difficult to compare sustainability of different FRP materials and production for processes. Concern for the environment, both in terms of limiting the use of finite resources and the need to manage waste disposal, has led to increasing pressure to recycle materials. This paper focuses on two issues that must be addressed to ensure continued growth in FRP usage is the disposal of waste generated during product manufacturing and the disposal of the products at the end of their useful life. The major cost drivers for FRPs are labor and raw materials. The use of recycled FRPS offers low-cost raw materials. This paper presents a review of the current status and outlook of FRP composites recycling and re-manufacturing techniques. A future vision for the use of FRP composites with sustainability applications is underway at many university research institutes and in industries. This paper will also state the sustainability problems of fiber reinforced composite products, and potential solutions.
