        abstract = {The anaerobic digestion of rotten grape fruit waste presents a viable strategy for mitigating greenhouse gas emissions and generating renewable energy. However, the process is frequently constrained by inhibitory compounds, pH fluctuations, and nutrient deficiencies, which can compromise biomethane yields and process stability. This study undertakes a comprehensive investigation of the synergistic effects of fish waste, prawn peel, bagasse charcoal, and wood ash supplementation on bio-methanation kinetics, methane content, and process robustness. The results reveal that the supplementation of rotten grape fruit waste with fish waste and prawn peel elicited a significant enhancement in biomethane production, concomitant with improved volatile fatty acid (VFA) metabolism and ammonia tolerance. The addition of bagasse charcoal and wood ash further augmented process stability and buffering capacity, thereby mitigating pH fluctuations and promoting a favorable environment for methanogenic archaea. Optimization of the supplementation strategy through response surface methodology (RSM) revealed a synergistic interaction between the supplements, yielding enhanced biomethane production and process stability. The findings of this study provide novel insights into the development of optimized supplementation strategies for enhancing bio-methanation of rotten grape fruit waste, thereby contributing to the advancement of sustainable waste management and renewable energy production.},
