Very good news as one more objection to wind energy may be blowing away. According to Energy Trend a resin has been developed that can be reused. From the article

In August 2022, Siemens Gamesa installed its first recyclable blades at the commercial Kaskasi offshore wind farm, and they have now discovered that the same style of fan blades can also be used in onshore wind turbines. Although wind power can bring a great amount of clean green electricity to the world, the recycling of wind turbines needs to be improved at this stage. Although 85% of wind turbines can be recycled after retirement, the huge blades can only be thrown into landfills. Therefore, Siemens Gamesa launched RecyclableBlade technology, hoping to recycle the composite blade material through a simple degradation process and reuse it in the wind turbine blade manufacturing process to solve the global problem of future offshore wind turbine blade replacement. The project partner, Aditya Birla Advanced Materials, uses a patented epoxy resin system that allows the recovery of composite materials using mild acidic solutions, allowing wind turbine blades to be reused or repurposed in the consumer product, construction or automotive industries.

So these are in production and hopefully will be very successful.

Other companies are grinding the blades and adding the material to concrete as a reinforcement or reusing parts of the blades for playground structures and pedestrian bridges. The major wind turbine companies are all working to make equipment that can be 100% recycled and there are some solid plans.
