Co-digestion is an efficient way to utilize different substrates to achieve better methane production and waste management. In this study, anaerobic co-digestion of vinasse (V), pomace (P) and aniseed (A) at 13 different ratio combinations were evaluated from the point of methane production performances. The methane production potentials of aniseed, vinasse, and pomace were determined as 444.1, 367.9, and 116.8 mL CH4 g−1 VSadded, respectively. The highest synergistic and antagonistic effects were obtained as 1.09 and 0.81 along with the 205.8 mL CH4 g−1 VSadded and 257.1 mL CH4 g−1 VSadded methane production potentials from the co-digested samples having ratios as A:V:P = 0:70:30 and A:V:P = 20:60:20, respectively. The co-digestion of aniseed with vinasse showed a positive impact on the methane production compared to pomace added co-digestion methane potentials. Addition of vinasse to pomace as a co-substrate improved the methane productions. The methane contents of produced biogas ranged between 56% and 67%. First Order, Cone, Modified Gompertz, and Reaction Curve models were applied to predict the methane production potentials. The R2values were calculated between 0.914 and 0.999 for the models. The ratio of A:V:P = 33:33:33 for the evaluation of alcohol distillery wastes from raki production by anaerobic co-digestion found as an appropriate option due to providing utilization of all wastes and adequate methane production. The findings of this study provided useful information for the evaluation of alcohol distillery wastes as a renewable energy source and gave a perspective about the practical application of the co-digestion process for industry as a waste management alternative.
