Evaluating Different Aspects of Biogas Production in Anaerobic Digesters

The key strategies to develop an alternative energy source instead of fossil fuels are outlined to compensate for current energy needs and to decrease environmental concerns such as high volume of waste pollution and global warming. So the economy and technologies largely depends on consistent renewable source with environmental criteria of biomass and actually biogas. Biogas technology is associated with certain limitations in addition to the many advantages. So that energy production is a difficult task without having stopping elements in which the alternative concepts is necessary to ensure sustainable development with accessible technologies. Further advances in technology led to renewed and deeper interest in biogas production, while it has great effects in reducing major economic problems in the world. The current review addresses the limiting factors and evaluation of recent technological advances associated with various aspects of biogas production such as the use of sustainable feedstocks, microbial and enzyme dynamics, optimization parameter and dissociation process to enhance this technology. Enzymatic bioassay and efficient microbial identification enables the energy of anaerobic digestion to be significantly enhanced. Therefore, optimization of different parameters to accelerate biogas production during anaerobic digestion has been preferred to pre- and post-anaerobic digestion. In spite of the development of multi-step digestion schemes in order to succeed in the separation process, further research is needed to achieve better system performance.
