This report provides a comprehensive assessment of decommissioned material waste streams from the wind energy sector in the EU until 2050, based on total wind installations in the EU until 2023. Our research focuses on 15 materials, including structural materials, electronic materials, the composite materials present in blades, and materials present in the permanent magnets; and explores each of these materials’ recyclability. By developing a robust decommissioning model and analysing the material intensities of various wind turbine components, we strive to provide a detailed picture of the quantities and types of materials that will be decommissioned in the coming years. The findings of this study will enable policymakers, industry stakeholders, and researchers to better anticipate the EU's recycling needs and develop effective strategies for managing the growing volume of wind energy waste streams.
