This dissertation study is a pilot-scale research aiming at to determine the biogas production potential of vegetable-fruit waste, which is a significant category of waste especially in the major cities. In the context thereof, Ankara vegetable-fruit market waste, which had not been studied previously, were used. Two-period, seasonal vegetable-fruit waste samples for the summer and winter months were collected in the scope of the study. The total humidity, ash, volatile substance, lower and higher calorie values, Sulphur (S), Nitrogen (N), Carbon (C), Hydrogen (H), and Oxygen (O) values were measured for the collected samples using standard methods. Methane production and biogas production potential were theoretically assessed in line with the experimental results. In accordance with the analysis results and theoretical computations it was seen that the lower and higher calorie values of the Ankara vegetable-fruit market waste varied between 3122-3638 kcal/kg, and 3438-3929 kcal/kg respectively. Furthermore, the C/N ratio in the vegetable-fruit market varied in between 8.3 21.3 interval. Compared to the findings reported in the relevant literature, the results of the study suggested that biogas production potential of the Ankara vegetable-fruit market waste was at a high level.
