Glass fiber-reinforced plastic (GFRP), a strong and durable composite material, is widely used in everything from aircraft parts to windmill blades. Yet the very qualities that make it robust enough to be used in so many different applications make it difficult to dispose of ⎯ consequently, most GFRP waste is buried in a landfill once it reaches its end of life.
According to a study published in Nature Sustainability, Rice University researchers and collaborators have developed a new, energy-efficient upcycling method to transform glass fiber-reinforced plastic (GFRP) into silicon carbide, widely used in semiconductors, sandpaper and other products.
“GFRP is used to make very large things, and for the most part, we end up burying the wing structures of airplanes or windmill blades from a wind turbine whole in a landfill,” said James Tour, the T.T. and W.F. Chao Professor and professor of chemistry and of materials science and nanoengineering. “Disposing of GFRP this way is just unsustainable. And until now there has been no good way to recycle it.”
