The unique combination of durability, chemical resistance, and changeable permeability of polyethylene terephthalate (PET) membranes has sparked significant interest in separation and filtration applications. The process of recovering PET from waste and using it to prepare and fabricatemembranes is an environmentally beneficial strategy that is in line with the worldwide movement towards circular economy principles. This comprehensive review explores the most recent developments in PET membrane studies, emphasising fabrication methods, membrane processes, and modification methods. The section on fabrication techniques offers a comprehensive analysis of conventional and novel techniques, emphasising the implications for membrane effectiveness, morphology, and structure. The in-depth review also looks at the application of PET membranes in purification and separation processes, particularly in microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and gas separation. To provide insight into the adaptability of PET membranes for various applications, performance parameters such as flux, selectivity, and fouling resistance are also covered. This article investigates the dynamic area of membrane technology, looking at the different improvements and alterations made to enhance PET membrane features. The purpose of this information compilation is to provide a useful tool for future research direction and inspiration for innovative developments in PET membrane design and use for diverse separation processes.
