: The increasing rate of oil and gas production has contributed to a release of oil-in-water emulsion or mixtures to the environment, becoming a pressing issue. At the same time, pollution of the toxic cigarette butt has also become a growing concern. This study explored utilization ofcigarette butt waste as a source of cellulose acetate-based (CA) polymer to develop phase inverted membrane for treatment of oil/water emulsion and compared with commercial polyvinylidene difluoride (PVDF) and polysulfone (PSF). Results show that CA-based membrane from waste cigarette butt offers an eco-friendly material without compromising the separation efficiency, with a pore size range suitable for oil/water emulsion filtration with the rejection of >94.0%. The CA membrane poses good structural property like established PVDF and PSF membranes with equally asymmetric morphology. It also poses hydrophilicity properties with a contact angle of 74.5°, lower than both PVDF and PSF membranes. The pore size of CA demonstrates the CA is within the microfiltration range with a mean flow pore size of 0.17 µm. The developed CA membrane shows a promising oil/water emulsion permeability of 180 L m-2 h-1 bar-1 after five filtration cycles.However, it still suffers a high degree of irreversible fouling (>90.0%), suggesting potential future 34 improvements in terms of membrane fouling management. Overall, this study demonstrates a sustainable approach to addressing oil/water emulsion pollution treated CA membrane from cigarette butt waste
