  • Abstract:
  • Biogas, a biofuel rich in energy content, primarily comprises methane. It serves as a sustainable alternative to natural gas or liquefied petroleum gas, offering considerable potential as a renewable energy source. Biogas mainly consists of methane (CH4) (50–75%), carbon dioxide (CO2) (25–50%), hydrogen sulfides (H2S), hydrogen (H2), ammonia (NH3) (1–2%), and traces of other gases such as oxygen (O2) and nitrogen (N2). Methane holds the potential to substitute fossil fuels across diverse applications, including heat and power generation, as well as within the transportation sector. It can be produced by the anaerobic digestion of various organic wastes. Anaerobic digestion of organic waste has garnered global recognition for its capacity to mitigate greenhouse gas emissions, decrease reliance on fossil fuel combustion, and support the development of a sustainable renewable energy infrastructure. Organic waste stands out as an ideal substrate for anaerobic digestion, owing to its exceptional biodegradability and elevated water content. Research has shown that anaerobic digestion, which converts organic waste into biogas, is a highly effective method for waste management. This process offers numerous benefits, including the reduction of pathogens and the prevention of odor emissions, thereby addressing key challenges associated with waste treatment. The most influential parameters on biogas production include feedstock characteristics (nutrient contents, particle size, and inhibitory compounds), and Factors influencing the anaerobic digestion process include process configuration, pH levels, temperature, retention time, organic loading rate, agitation, hydrogen concentration, moisture content, and the type of inoculum used. These parameters play crucial roles in determining the efficiency and effectiveness of biogas production from organic waste. Challenges and future perspectives on biogas production from various organic wastes are also discussed to improve the performance of anaerobic digestion technology.
