In the present study, anaerobic treatment of food wastes from restaurants of a fermentation industry and methane gas production
yields produced during the treatment were investigated. For this purpose, food wastes with a Total Solid Contents (TS) ratio of 5-
7-10% were digested in a 100l experimental reactor. Batch anaerobic digestion studies were conducted at mesophilic
temperatures (36.5 oC) for 30 days and optimum Volatile Fatty Acids (VFA) and alkalinity values for methane gas production
were ensured. Methane gas production yield was assessed with respect to Total Organic Carbon (TOC) and Chemical Oxygen
Demand (COD) degradation. At the end of the study, methane yield was obtained as 466-501-498 l/kg VS according to initial
mixtures of 5-7-10% TS. Degradation occurred in the interval of 40-46% for COD and in the interval of 25-65% for TOC. As a
result, it was seen that food wastes have high biodegradability and high potential for methane gas production.
