Abstract

In this study, anaerobic digestion was used to manufacture biogas from food waste. To improve production digester performance and biogas generation, chicken manure and slaughterhouse waste were added. The Bach feeding system with two digesters was followed by a laboratory fermenter. Bones were put to the second fermenter after the first fermenter was loaded boneless. The anaerobic digestion of food waste was simulated using two steps of Aspen Plus. According to experimental data, the first reactor generated the most gas on the seventh day, with 0.357 liters, while the second digester produced 0.24 liters. Aspen Plus simulation findings showed 42.38% CO2, 5.8% traces, and 50.82% methane. This illustrated how closely the biogas's composition matched that of the traditional.
