Abstract: The environmental pollution and resource wastage caused by the waste blades of wind turbines are becoming increasingly severe. How to make use of the waste blades efficiently is a critical bottleneck and a major challenge in the development of the wind power industry. The technology of pyrolysis recovery is relatively mature, and it is the primary method for the resource utilization of waste blades. Based on the material composition of waste blades, the pyrolysis mechanism of waste blades and the resource utilization of pyrolysis products such as pyrolysis oil, glass fibers and carbon fibers were reviewed, and some suggestions were put forward to solve the problems in the utilization of pyrolysis products.

Key words: waste wind turbine blade, pyrolysis, epoxy resin, glass fiber, carbon fiber, resource utilization
