“…In many of these countries, the need for excessive governmental subsidies has resulted in installing this technology only during the specific periods where these tariffs offer the highest return of investment. Therefore, it is a priority to give a feasible solution to all the different factors extensively analyzed by several authors and to the difficulties that the digestion process encounters to become a successful alternative for waste management [14][15][16].…”

Anaerobic digestion is traditionally used for treating organic materials. This allows the valorization of biogas and recycling of nutrients thanks to the land application of digestates. However, although this technology offers a multitude of advantages, it is still far from playing a relevant role in the energy market and from having significant participation in decarbonizing the economy. Biogas can be submitted to upgrading processes to reach methane content close to that of natural gas and therefore be compatible with many of its industrial applications. However, the high installation and operating costs of these treatment plants are the main constraints for the application of this technology in many countries. There is an urgent need of increasing reactor productivity, biogas yields, and operating at greater throughput without compromising digestion stability. Working at organic solid contents greater than 20% and enhancing hydrolysis and biogas yields to allow retention times to be around 15 days would lead to a significant decrease in reactor volume and therefore in initial capital investments. Anaerobic digestion should be considered as one of the key components in a new economy model characterized by an increase in the degree of circularity. The present manuscript reviews the digestion process analyzing the main parameters associated with digestion performance. The novelty of this manuscript is based on the link established between operating reactor conditions, optimizing treatment capacity, and reducing operating costs that would lead to unlocking the potential of biogas to promote bioenergy production, sustainable agronomic practices, and the integration of this technology into the energy grid.

“…For the assessment of creditworthiness, several studies have shown that, even in the renewable energy sector, financial operations have the characteristics of legal isolation and isolation of financial flows [121,122]. These characteristics assimilate financing operations in renewable energy to pure project financing operations (PFOs), conducted on special purpose vehicles (SPVs).…”

The biogas sector in Europe and Italy is attracting growing investment, combining agricultural activity, the circular economy, and renewable energy production. Firms in the sector widely use debt capital and, for this reason, there is a need to evaluate the structure of investments, financing, and debt service capacity calculated by applying interest coverage ratios (ICRs). ICRs are widely used by banks in granting loans, and calculation of ICRs allows managers and policy makers to correctly evaluate firms’ performance in the sector. In this research, based on a sample of 160 observations, the structure of investments and sources of financing of firms in the biogas sector, operating in northern Italy, are analyzed. ICRs are calculated with different approaches to establish which ICRs provide the most reliable results in the application. The research analyzes the correlations and highlights significant differences between ICRs. The research highlights some important findings: (a) the NWC is negative in 109 out of 160 observations and, therefore, constitutes a source of financing in the majority of observations; (b) ICRs based on EBITDA and CF are above the threshold value of “1” in 143 and 145 observations, respectively, while ICRs based on EBIT, OCF, and UFCF are above the threshold value of “1” in 132, 133, and 122 observations, respectively. The research allows the conclusion that the ICRs based on EBITDA and CF tend to overestimate results; ICRs based on EBIT, OCF and UFCF are preferable, and can therefore be applied by managers, banks, and policy makers and be used as debt covenants. For the calculation of the repayment of the NFP, the research has highlighted that ICRs in which the cost of the debt is deducted from the numerator are preferable. The research can thus be usefully applied and expanded to other territories, or by considering a larger sample with the aim of inferring conclusions of general validity.

“…The development of the biogas industry is influenced by a wide range of political, economic, and social variables, including regulations in the areas of energy, the environment, agriculture, banking, and education, among others. Both effective coordination between the decision-makers from the aforementioned domains and active participation of the professionals and associations of profile in the process of policy creation is necessary for the growth of this relatively new economic sector [26].…”

A promising sustainable method for generating energy from municipal, industrial, and animal wastes is biogas. The development of biogas can be combined with plans to enhance sanitation, lessen indoor air pollution, and cut greenhouse gas emissions. In addition to providing a techno-economic feasibility analysis of biogas plants, this research intends to identify technical and non-technological constraints preventing the widespread use of biogas in India. Different waste, renewable energy, and urban regulations have an impact on the distribution of biogas. Therefore, specific obstacles to India's current rural and urban biogas systems were identified. The findings demonstrate that there are significant differences in the nature and significance of obstacles amongst biogas systems due to variations in technological maturity, feedstock quality and availability, supply chain, awareness level, and policy support. The developed excel model also provides a full perspective of the economic factors used to assess the viability of a biogas plant project. Users may assess numerous situations and decide on the best course of action for their investment in the biogas sector by using a comparison and analysis technique.
