| Abstract | Biogas production by anaerobic digestion is a potential technique for waste management and reduce carbon footprint. Heat capacity and fuel efficiency of biogas make it as an interesting alternative to the depleting nonrenewable fuels. The full potential of anaerobic digestion is not realized yet due to operational difficulties, government policies and people acceptance. This review focuses on the bottle necks in the biogas production technology and highlights some of the recent technology that can be adopted to achieve circular economy in biogas sector. In a waste to energy perspective, the presence of recalcitrant lignocelluloses in the available biowaste is discussed. Various pretreatment techniques used to convert these recalcitrant materials to suit anaerobic digestion are compared. Microalgal culture techniques for waste treatment and biogas upgradation are seen as a promising strategy towards clean energy. In many cases the impurities present in the biogas limit its usage. Hence, more emphasis for biogas upgradation by adopting advanced methods like facilitated transport in a nanocellulose membrane is needed. Implementation of biogas as an alternative to fossil fuels has both technological and policy related barriers. Biogas helps to attain sustainability development goals proposed by the United Nations. This review discusses the technological aspects of biogas production alongside the application of biogas to attain sustainability in the fuel sector. In various sections, we highlight the technical difficulties in biogas production, solutions for those problems, and potential of biogas technology in achieving sustainable goals. |
