Abstract	Vinegar residue (VR) is a by-product which produced by the process of vinegar production. To enhance the performance on methane production of VR and facilitate its resource utilization, sodium hydroxide (NaOH) pretreatment was carried out. Results showed that with the concentration of NaOH increased, the cumulative methane yield ascended first and then declined. At NaOH concentration of 3.0 %, the cumulative methane yield was 205.86 mL g VS −1 and improved 53.99 % comparing with the untreated VR. Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, and component analysis demonstrated the structural and compositional changes in VR after NaOH pretreatment. The results obtained in this study proved that NaOH pretreatment was really efficient for enhancing the capability of anaerobic digestion (AD) and increasing methane production. Through this technology, it not only provides a method to reduce the pollution to environment but also contributes to clean energy production. Meanwhile, the results of this research may serve as a promising and potential way for AD of VR in the future industrial applications.
