Developing an Extracting Method of Laminated Glass-fiber from FRP Boats

There is several basic classes of recycling methods for FRP boats. The main one is mechanical recycling that is one of the simpler and more technically proven methods. It recently has been reported that FRP can be recycled by separating into laminated glass-fiber layers instead of crushing into powder. These mechanical recycling will be hopeful for the eligibility. Nevertheless, because resins are very useful renewable energy, most of FRP waste regenerating methods are depended on incineration (reclamation) or thermal recycling (pyrolysis). Due to the extremely high fossil energy the waste plastics should be regenerated to the source of renewable energy. But FRP is made up of laminated glass-fiber (roving cloth layer) which is fire-retardant substances, also very hard to break into each layer. Therefore, if there is an extracting method which is efficient and environment friendly removing glass fiber from FRP waste, it could also solve the early mentioned and urgently demanding problem of renewable energy. Laminated glass-fiber which is very limited recyclable is currently a serious barrier to waste FRP boat regenerating. This study is to propose a new extracting method which is efficient and environment friendly FRP waste regenerating system. Then the recycled glass fiber was obtained by the separation of the roving layer from FRP waste will be consider to be useful for concrete products or concrete structures as fiber reinforced material. And it should be successively applied to renewable energy applications using the waste resins of FRP residue without laminated glass-fiber.
