ABSTRACT: The world’s population is growing, and development is expanding quickly, which has increased the demand for energy supplies. Developed nations have incorporated renewable energy sources into their policies for a sustainable future. Alternative and renewable kinds of energy have been developed due to the growing concerns about the sustainability of our world. One example is the creation of biogas using waste (such as sewage sludge, forest residues, agroindustry, and food processing). It is mainly composed of methane and carbon dioxide.
