Conversion of biowaste to biogas: A review of current status on techno-economic challenges, policies, technologies and mitigation to environmental impacts

Abstract Anaerobic Digestion (AD) could be a promising methodology to convert biowastes to sustainable fuel for applications like power generation, heating, drying, cooling and so on. Forceful amendment in technologies, government policies, social behavior and economic aspiration cause vital analysis of those factors for successful generation of energy from biowastes. To accomplish the need, the current review deals with the status of biowastes utilization, biowaste conversion technologies and influencing parameters of the conversion process. This paper conjointly reviews totally different pre-treatment and co-digestion ways that improve the effectiveness of AD. Moreover, the economic merits of these well-studied technologies are summarized and compared in terms of autoclave performance, environmental advantages, and the status of real-world applications.
