As the main utilization form of wind energy

wind power generation is one of the most dominant methods of power generation in the field of global renewable energy. With the rapid development of wind power industry

a batch of wind turbines installed in the early stage will also be centrally decommissioned

resulting in a large number of waste blades. Under the background of the goal of “carbon peak and carbon neutralization”

the recycling and reuse of waste blades has attracted extensive attentions. Nevertheless

the recycling of wind turbine blades remains a huge challenge due to the difficulty of degrading the composites currently used in the blades and the complexity of recycling process. The current situation of wind power generation is introduced

the materials for blades and their performance characteristics are also expounded. Besides

the existing thermal recycling methods are discussed in detail and compared with mechanical recycling method and chemical recycling method

and then the advantages and disadvantages of each recycling technology are analyzed. Reasonable suggestions for large-scale recycling of wind turbine blades are provided

so as to realize green recycling of wind turbine blades and ensure the sustainable

healthy and green cycle development of wind power industry.
