The wastewaters of three agro-industries in Eskişehir, namely cake production, cheese-making and beet molasses alcohol distillery industries, were studied for their potential for anaerobic treatment and methane generation. biochemical methane potential experiments were conducted for different initial chemical oxygen demand concentrations both with and without a basal medium. the results revealed that nutrient and trace metal suplementation is vital for the anaerobic treatment of the wastewaters studied. anaerobic methane generation was found to be 1062 ml ch4/g cod (12.7 l ch4/l wastewater) for the cake production wastewater, 366 ml ch4/g cod (10.98 l ch4/l wastewater) for the cheese whey, and 222 ml ch4/g cod (6 l ch4/l wastewater) for the alcohol distillery wastewater. the results indicated that anaerobic treatment was possible for all of the wastewaters studied and the produced biogas had a high methane content.
