Abstract With the progressive replacement of early-21st-century wind-power equipment, end-of-life wind-turbine blades made of carbon-fiber-reinforced polymer (CFRP) present a significant disposal challenge due to their poor natural degradability, making pyrolysis the mainstream treatment route. To simplify processing and minimize fiber damage, this study investigates direct pyrolysis of structural-scale CFRP specimens (50 × 10 × 20 mm) in a fixed-bed reactor. The overall mass loss stabilized at
