Evolution of biogas production potential of waste macroalgae collected from Marmara sea together with organic wastes

In this study; it is aimed to use macroalgae collected from coast of Marmara Sea and organic wastes taken from market place as useful products. In this context, bio methane potential (BMP) reactors are set up in three different systems within macroalgae and organic wastes. In the first system, the effect of different S/M (substrate/microorganism) ratios on biogas formation was investigated. In the second system, the effect of temperature on the reactors with the best results in the first system was investigated. Reactors were operated temperatures at 35, 45 and 55o C. In the last system, the effect of pretreatment on biogas formation was investigated. The highest amount of methane obtained in the first system were measured in reactors C2-35 and C3-35 with 167 L CH4/kg VS and 197 L CH4/kg VS, respectively. In the second system, 15 L CH4 /kg VS and 17 L CH4/ kg VS were measured for the C2 and C3 reactors, respectively. In the last system, the biogas and methane yields obtained in the C2-K35 reactor were measured as 282 Lbiogas/kg VS and 154 L CH4/kg VS, respectively. In the C3-K35 reactor, the biogas and methane yields obtained were measured as 287 Lbiogas/kg VS and 147 L CH4/kg VS, respectively.
