Fiberglass, the main material in wind turbine blades, does not offer much value after use, and recycling efforts have hence been low.

However, landfilling may currently be the most cost-effective strategy. While this announcement is the first of its scale from the world's largest turbine producer, Vestas has a long road ahead in valorizing sustainability for wind. If successful, it may be key for Vestas to differentiate itself against major competitors Siemens Gamesa and GE. Still, Vestas must create more value beyond just zero-waste, like with refurbishing and buyback programs, to surmount present economics.
