Governments have invested heavily in biofuels due to the growing demand for them as fossil fuel substitutes, as well as challenges with national security, increasing farmer income, implementing new and cutting-edge technologies, and environmental and health concerns. Despite the agriculture industry having many potential facilities and producing a sizable number of crops each year, a lot of trash is regrettably abandoned or thrown in the environment without according to environmental laws. As a result, economical and technological advancements are crucial to the development of biogas and other environmentally acceptable renewable energy sources. Because producing energy in the absence of obstructions might be difficult, biogas technology has both advantages and disadvantages. In order to ensure sustainable development, it is vital to update present technology. More advancements have turned focus to biogas production techniques, which may greatly lessen potential worldwide economic problems. The goal of the current study was to assess recent technological developments as well as various aspects of biogas production, such as the use of sustainable raw materials, microbial dynamics, and enzymatic activities, as well as optimization parameters and segregation processes, to improve this technology and investigate potential inhibitors.
