The focus of this study is to contribute toward the recycling of end-of-life wind turbine blades through the oxy-liquefaction technique under subcritical water conditions. Wind turbine blades have complex composition and it’s not an easy task to separate their components so the premise for recycling is a mixed waste stream where little is known about the chemical composition. The treatment of selected waste material is carried out at the temperature range of 250 to 350oC with starting pressure of 20 to 40 bar. The effect of varying weight percentages of oxygen, waste to liquid ratio and residence time on the product composition has also been studied. BTX compounds including benzene and toluene, volatile fatty acids including acetic acid, and dodecanoic acid followed by palmitic acid were the major products of the oxy-liquefaction reaction. Dependency of total solid reduction and the acetic acid yield on various parameters is also verified statistically through ANOVA analysis. The high concentrations of acetic acid products offer opportunities for recovery and re-use if effectively managed therefore such a process can provide a significant commercial and environmental benefits
