This systematic review evaluates the potential of biogas as a sustainable energy source derived from biomass for renewable solutions. Biogas production involves the anaerobic digestion of organic materials, such as agricultural residues, municipal solid waste, and livestock manure, to generate methane-rich gas for electricity generation, heat production, and transportation fuel. The systematic review study comprehensively examines various aspects of biogas, including its production process, environmental benefits, economic viability, technical considerations, challenges, social impacts, circular economy principles, technological innovations, public perception, policy recommendations, and alignment with global climate goals and Sustainable Development Goals. Key findings indicate that biogas offers significant potential to mitigate greenhouse gas emissions, reduce organic waste pollution, promote sustainable agriculture, and create economic opportunities. However, challenges such as technological limitations, financial constraints, and policy barriers impede the widespread adoption of biogas. Policy recommendations emphasize the importance of supportive regulatory frameworks, incentive programs, and international cooperation to facilitate biogas development. Overall, this systematic review provides understanding into the role of biogas in advancing renewable energy solutions and underscores the need for concerted efforts to realize its full potential in combating climate change and promoting sustainable development.
