“…An imbalance between energy demand and supply hinders economic development, prosperity, and sustainable growth and seriously affects a country’s water resources, environment, human health, and agricultural output (Jha and Schmidt 2021 ). Even though various vitality plans foresee a bright forthcoming for renewable energy improvement, in the southern part of the globe, 250 million people still rely on traditional energy sources for heating, cooling, lighting, and other daily requirements (e Silva et al 2022 ), the energy area was forced to endure a great surprise throughout the COVID-19 epidemic, impeding the energy alteration (Zhang et al 2021 ).…”

After COVID-19, financing for emerging nation reserves in renewable energy bases was deemed a crucial aspect of sustainable development. Investing in biogas energy plants can be highly beneficial for lowering the use of fossil fuels. Using a survey of shareholders, investors, biogas energy professionals, and active social media participants in Pakistan, this study evaluates the intentions of individual investors to invest in biogas energy plants. The primary purpose of this study is to increase investment intent for biogas energy projects following COVID-19. This study focuses on financing biogas energy plants in the post-COVID-19 era and evaluates the research’s assumptions using partial least squares structural equation modeling (PLS-SEM). The study employed the technique of purposive sampling to acquire data for this investigation. The results indicate that attitudes, perceived biogas energy benefits, perceived investment attitudes, and supervisory structure evaluations inspire one’s propensity to finance biogas vitality plant efforts. The study found a link between eco-friendly responsiveness, monetary benefits, and investors’ actions. The aspiration of investors to mark such reserves was set up to be unpretentious by their risk aversion. Conferring to the facts, evaluating the monitoring structure is the critical factor. The previous studies on investment behavior and other forms of pro-environmental intent and action yielded contradictory results. In addition, the regulatory environment was evaluated to see how the theory of planned behavior (TPB) affects financiers’ objectives to participate in biogas power plants. The consequences of the study indicate that feelings of pride and discernment of energy expansively affect people’s desire to invest in biogas plants. Biogas energy efficacy has little effect on investors’ decisions to invest in biogas energy plants. This study offers policymakers practical ideas on enhancing investments in biogas energy plants.

“…Embora todas as fontes renováveis desempenhem papéis de relevância no contexto energético brasileiro, a obtenção de biogás, tem ganhado atenção nos últimos anos. No entanto, o biogás obtido de dejetos provenientes da pecuária tem se destacado (SILVA et al, 2022).…”

“…It is a complex biological process in which organic raw materials are converted into biogas, by means of a consortium of microorganisms that are sensitive to or completely inhibited by oxygen (Sánchez-Hernández et al , 2013) et al , 2022) Many studies explored the anaerobic digestion process for many different types of biowastes which affect biogas production according to their type, nature, and concentration. These biowastes are chicken manure (Jurgutis et al , 2020(Jurgutis et al , , mahmoud et al , 2022, sewage sludge (Abdel daiem et al , 2021, Jeong et al , 2021, cow manure (Jafari-Sejahrood et al , 2019, McVoitte andClark, 2019), swine manure (de Castro e Silva et al , 2022, Hollas et al , 2021, macroalgal biomass (Farghali et al , 2021), cattle manure (Dong et al , 2019), submerged aquatic plant (Hydrilla verticillata) (Chen et al , 2016), corn stover (Arias et al , 2021), food waste (Anaya Menacho, Mazid, 2022, Muratcobanoglu et al , 2020), vegetable peel (Lahbab et al , 2021, pig manure (Li et al , 2020), sheep manure (Li and Zhang, 2022), wild tree wastes (Mahmoodi-Eshkaftaki and Mahmoudi, 2021), rice straw (Mussoline et al , 2012), Buffalo grass (Sawanon et al , 2022), cotton straw (Wang et al , 2021), poultry manure (Yılmaz and Şahan, 2020).…”

In this study, a medium scale biogas digester has been operated to treat the cattle manure of 50 animals producing about 1000 kg of manure per day. The volume of digester is 200 m 3 and was designed to produce biogas for a 50 kWh/day electric generator and 28 day the hydraulic retention time (HRT) with daily feeding rate 6 m 3 of substrate. From the evaluation results, the daily feeding rate is 5 m 3 and HRT of 40 day. The biogas yield reached 11.51 m 3 /day and the CH 4 and CO 2 concentration ranged from 37 % to 61 % and from 13.3 % to 37.8 %, respectively. On the other hand, a reduction in the organic contents of substrates is explored because of the anaerobic digestion process. These contents are volatile fatty acids (VFAS), carbon to nitrogen ratio (C/N), volatile solids (VS), and chemical oxygen demand (COD), where the maximum reduction percentages of VFAS, C/N ratio, VS, and COD are 78.2 %, 76.7 %, 76.5 %, and 87.0 %, respectively. Furthermore, the concentration of total nitrogen (TN), total phosphorus (TP), total potassium (TK), NO 3 -N, and NH 4 +N achieved an increase in the digestate compared with their corresponding values in substrates, especially TP and TK. From the evaluation results, we can put and illustrate some important issues that may increase the biogas digester efficiency; (1) the biogas purification unit should be fixed and operated to reduce the CO 2 , H 2 S and O 2 contents, (2) The substrate pH, and total solid should be more controllable, (3) The digestates should be treated before use for further benefits and more stable with environment, and (4) a periodically maintenance plan should be followed for improving biogas production and increase the life time of the digester components.
