With the rapid development of wind power industry, the number of wasted wind turbine blades increased significantly year by year, which brings great environment pressure. Against this problem, the influence of atmosphere on the generation characteristics of gas, liquid and solid products of wasted wind turbine blades during thermal treatment at different temperatures was studied, to provide reference for thermal recovery strategies. The results showed that, in N2 and CO2 atmospheres, the production of combustible CH4 reached the highest at 800 ℃, that of CO increased with temperature. Tar products in each atmosphere mainly consisted of p-isopropenyl phenol, p-isopropyl phenol and bisphenol A. Moreover, it was found in the experiment that, at high temperature, CO2 in the atmosphere effectively prevented the formation of polycyclic aromatic hydrocarbons (PAHs) in tar, which is helpful to subsequent treatment of tar. It is also found that, the coke yield in air and CO2 atmosphere was higher than that in N2 atmosphere, however, at higher temperatures (600 ℃ and above), the results were opposite. This may be due to different carbonization levels in different atmospheres at low temperatures.
