This study investigated the effects of cellulose sponge media as biocarriers on methane (CH4) production in two upflow anaerobic sludge blanket (UASB) reactors treating fresh landfill leachate. UASB I was operated with anaerobically acclimatized sludge supplemented with propionate-cultured sludge, while UASB II contained the same inoculum augmented with 20 % (v/v) cellulose sponge media. Luffa-based cellulose sponges, derived from agricultural waste, are environmentally benign and serve as low-cost biofilm carriers. Experiments were conducted under four organic loading rate (OLR) conditions: 66.96, 47.01, 27.07, and 6.78 gCOD/L d. Results showed a positive correlation between OLR and CH4 production, with maximum CH4 yields of 17,185 mL/d in UASB I and 28,917 mL/d in UASB II at the highest OLR (66.96 gCOD/L d). Incorporation of cellulose sponge media enhanced microbial attachment and diversity, thereby improving methanogenic activity and overall CH4 recovery. These findings demonstrate that plant-based biofilm carriers such as luffa-derived cellulose sponges can improve UASB performance in treating landfill leachate. The study highlights the valorization of agricultural waste-derived materials for sustainable biogas production and effluent quality improvement. The novelty of this study lies in the application of cellulose sponge in the anaerobic treatment of high-strength landfill leachate. This study specifically examined the potential of luffa-derived cellulose sponge as a biofilm carrier under anaerobic conditions, with the dual objectives of enhancing biogas production and improving effluent quality. © 2026 Elsevier Ltd
