The global energy crisis is a critical issue today, particularly given the threat of depletion of nonrenewable energy resources such as fossil fuels. As a result of this problem, it is critical to consider the use of renewable energy resources such as biomass energy. As a result, this work develops a mobile unit of biogas (1000 L) to be used for biogas production based on lab-scale (25 L) experimental results. At the start of this study in the winter, a small scale fermenter is used to ensure the production of biogas, which is observed after 20 days. Then, as feedstock, 25 kg of cow manure and other animal and agricultural wastes are used. Following that, a fixed digester with an agitator is designed to produce biogas; additionally, a floating dome digester and a fixed brush digester are used to produce biogas. For lab-scale and large-scale units, the biogas production rate is approximately 35 and 140 L/kg VSS, respectively. The presented method is simple, requires no mechanical or electrical components, is easily constructed, and produces gas at a low cost
