Abstract: With the rapid development of the wind power industry, the management of end-of-life wind turbine blades has become a significant global challenge, as their accumulation not only occupies substantial land resources but also poses potential environmental risks. Pyrolysis of end-of-life blades can yield solid glass fiber residues and liquid phenolic products, among which phenolic compounds can be widely applied in the plastics, pharmaceutical, and chemical industries, offering considerable potential for resource recovery and high added value. To maximize recycling efficiency, this study investigates the pyrolysis characteristics, including product distribution and liquid-phase composition, of different blade components, such as glass fiber reinforced plastics （GFRP） and core materials including balsa wood, polyethylene terephthalate （PET）, and polyvinyl chloride （PVC） foam. An innovative strategy is proposed in which ZnCl₂-activated balsa wood-based activated carbon （ZnCl₂−AC） is prepared and employed as a catalyst for the co-pyrolysis of GFRP sections （EolWTB-3） and PVC-filled sections （EolWTB-4） to enhance the yield of phenol and phenolic compounds. The results show that when the blending ratio of EolWTB-3 to EolWTB-4 is 0.75∶0.25 and the catalyst （1ZnCl₂−1AC） is prepared using a 1∶1 ratio of balsa wood core to ZnCl₂, the selectivity of phenol and total phenolic compounds reaches 76.27% and 96.27%, respectively. Reusability tests further indicate that the catalyst maintains stable selectivity toward phenol over multiple cycles. Based on this, a novel technical framework of “blade-derived catalyst–directional catalytic pyrolysis–synergistic utilization of multiphase products” is proposed, which demonstrates clear advantages in terms of industrial feasibility and environmental impact, providing a promising pathway for the large-scale and high-value utilization of end-of-life wind turbine blades.
