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. Solid waste management and energy demand are becoming major challenges due to rapid urban growth. Biogas energy production can meet energy needs and assist in managing biodegradable waste. It can be produced from the organic portion of municipal solid waste in landfills and used as a substitute energy source in cities. Urbanized and industrialized areas suffer from severe environmental issues that produce organic residues. It can be used as fuel for cogeneration systems, vehicle mobility, home heating, and other uses. This research aims to assess biogas’s production potential and potential for use as a substitute energy source in urban and rural settings.
