Biogas, a mixture of methane and carbon dioxide, is produced through the anaerobic digestion of organic materials where microorganisms, under oxygen-free conditions, convert organic materials through four stages: hydrolysis, acidogenesis, acetogenesis, and methanogenesis. This renewable and sustainable energy source significantly contributes to reducing dependence on fossil fuels, decreasing greenhouse gas emissions, managing organic waste effectively, and preventing soil and water pollution. In this study, the ADM1 model was used to simulate the conversion of organic materials into biogas, with simulations conducted using Aspen Plus and MATLAB software. The system simulated consists of two...
