“…The content of the digestion mixture affects the mixing process taken place in anaerobic digestion. 74 One advantage of mixing is the tendency to allow uniformity in the digester or reactor. 70 The kinetics of anaerobic digestion and biological processes increases with respect to mixing.…”

The authors reviewed the future prospects and previous studies on anaerobic digestion technology for biogas production and highlight the solutions to problems relating to construction and maintenance of biogas digesters, which can now be accessed in a single paper. It is the aim of the review to provide insight into the use, process and application of anaerobic digestion as an appropriate technology for biogas production from peer reviewed literature. Recent studies have shown that the microbial communities and metabolic pathways involves in anaerobic digestion are influenced by temperature. Their metabolic activities increase significantly with increase in temperature. Therefore, the findings of the review reveal that temperature is a major parameter for biogas production due to its influence on metabolic activities involved in anaerobic digestion. Hence, there is the need for insulation as well as external heating to maintain temperature stability and to avoid temperature fluctuations. More also, the anaerobic digestion technology for production of biogas is a viable option that can supplement as well as reduce the usage of non-renewable energy sources such as fossil fuel. The detailed information addressed in this study would increase biogas energy mix as well as mitigating climate change. Therefore, the study recommends the use of biogas as a clean energy for the purpose of power generation, cooking and heating.

“…However, only a few MSWMS involve a biogas plant, e.g., in Poland, only six. The high costs and/or complexity of the logistical operations have hampered full-scale implementation [9,10]. However, waste to energy via biogas seems to be an idea that could become a viable option for countries and cities nowadays.…”

This study investigated the applied methods for the collection and treatment of an organic fraction of municipal solid waste with anaerobic digestion (AD), including the effects of selective waste collection system introduction. As the research area, data from a waste treatment plant, which collects waste from about 260,000 inhabitants, was used as the selected waste management plan. Biowaste stream management was emphasized. Thus, research on energy recovery and the characteristics of digestate (nutrient and heavy metals content) obtained from biowaste AD was performed. The results of the studies and their quantitative data were interpreted. A significant discrepancy between the assumptions and the actual situation was revealed (up to 20% year-on-year regarding biowaste). An underestimation of the amount of waste when planning was noted. AD ensures energy recovery from biowaste, which can cover facility electricity needs and material recovery. The digestate might find agricultural usage and become an ecological product. The content of nitrogen (1.5%dry matter), phosphorus (0.55%dry matter), potassium (1.0%dry matter), and organic carbon (16.0%dry matter) indicate a positive impact on crops. Furthermore, it can improve the economic balance, by replacing costs with sales revenues.

“…However, despite a large amount of literature found on MSW management systems, converting waste to energy obtained from the biomass chain → biogas → electricity and/or heat receives little attention. This could be explained by the incumbent high costs and/or complexity of the logistical operations that may hinder scale implementation [14][15][16].…”

Cities around the world should prioritize the management of municipal solid waste (MSW). For this to be effective, there is a strong need to buildup a complex system that involves social, economic, and environmental processes, leading to a supply chain (SC). The actors involved in dealing with MSW—from suppliers, collectors, distributors, industries, and managers—should be engaged in strategic planning. This paper focuses on alternative energy solutions and uses existing SC models of managing MSW, as well as the existing literature, to identify successful stories in cities like Bergen and Tønsberg in Norway, London in UK and Barcelona in Spain and draw a conceptual framework for city officials in Romanian municipalities (but not only) to innovate—and convert MSW in biogas to be used in delivering public services, i.e., public transportation. The article shows that when the innovation is accepted and well implemented by all actors, the benefits for the citizens and the municipality are considerably higher than by using conventional methods of collecting and depositing MSW. The proposed approach is also relevant for implementing the EU environment policy, where delays are usually observed (as the case for Romania).
