Type: article
Abstract: The present study evaluated the impact of chemical pre-treatment on biogas and methane generation from corn and wheat stalks. Three types of animal manure were used as a source of bacteria (cow, cattle and ostrich manure). Chemical treatment using sodium hydroxide led to an increase in biogas and methane generation from wheat and corn stalks, where the increase for wheat stalks pretreated with cow, cattle and ostrich manure was (468.28; 469.08%), (242.51; 230.39%), (317.90; 295.77%) respectively compared to the untreated sample. As for corn stalks, the increase for biogas and methane with the same wastes above was (345.28; 444.59%), (230.90; 291.20%), (277.99; 297.011%) respectively compared to the untreated sample. With a correlation coefficient of more than 96, the findings also demonstrated that the values that were measured and the values that were derived by using the modified Gompertz model were in accord with one another
