High cost of recycling wind turbines

While the turbines' steel and concrete can be disposed of without greater problems, the UBA found that the rotor blades will pose particular problems as the materials they are made of are difficult to separate properly. By 2024, about 70,000 tonnes of old blades could pile up annually in Germany alone. Moreover, the reserves set aside by operators could fall short of covering the financial needs by hundreds of millions of euros by 2038, which is why the UBA recommends reviewing the reserves' calculation base and have them reviewed by independent experts on a regular basis.
