The blades aren't just fiberglass but a complex mixture of FRPs which includes glass, plastic, binders and resins. Furthermore, they're layered and vary with distance from the hub and position on the airfoil. Recycling them isn't impossible, just more difficult because of the nature of separating components and removing undesirable/unreusable components. Although the do carry incredible forces (not quite in the region of turbojet/turbofan blades but still impressive), there's probably more work to be done to make the blades fully lifecycle-designed to make them easier to recycle.
