“…Renewable energy refers to the energy from the existing energy flow in the ongoing natural processes. In other words, it is defined by the ability to renew itself more quickly than the exhaustion rate . The important point is that it is not possible to consume renewable energy resources permanently.…”

Summary This study aims to assess global investment alternatives with respect to renewable energy. Within this framework, five different renewable energy types (biomass, hydropower, geothermal, wind, and solar) are determined as investment alternatives. Moreover, eight different criteria are selected by considering the four different dimensions of balanced scorecard. Additionally, the fuzzy‐based decision making trial and the evaluation laboratory under the hesitancy (HF‐DEMATEL) model are taken into the account to weight these dimensions and criteria and the technique for order the preferences by the similarity to the ideal solution with the fuzzy hesitant methodology (HF‐TOPSIS) is considered to select the alternatives of renewable energy investments. The novelties of this study are to propose an integrated model and provide the balanced scorecard–based evaluations of global renewable energy investment alternatives. The findings show that learning and growth and customer are the most important dimensions for the investment on renewable energy. It is also identified that market potential, product customization, and technological development are the most significant criteria for this situation. On the other side, solar and wind energy are the most important renewable investment alternatives. These results explain that technological improvement should be maintained, and customer expectations should be met by the companies. Furthermore, solar power plant and wind power plant should be developed in the countries. For this purpose, governments should give necessary incentives to the investors, such as allocating appropriate lands. These actions can attract the attentions of the potential investors for these renewable energy alternatives. Owing to this issue, it can be possible to increase the capacity of electricity productions in the countries with a potential minimum cost.

“…Today, despite the ever-increasing environmental concerns over the dependency on non-renewable energy resources, the major global energy systems still depend on fossil fuels (Florio et al, 2019;Lim & Biswas, 2019;Nosratabadi et al, 2019;Sharma, Ansari, Pal, Singh, & Lalhriatpuia, 2019;Škapa & Vochozka, 2019;Tabesh, Feizee Masooleh, Roghani, & Motevallian, 2019;Torabi, Hashemi, Saybani, Shamshirband, & Mosavi, 2019). However, because of environmental concerns, the world is shifting towards renewable energy resources (Afsharzade et al, 2016;Baena-Moreno et al, 2019;Eder & Mahlberg, 2018;Lyytimäki, 2018;Nethengwe, Uhunamure, & Tinarwo, 2018;Rosa et al, 2018;Vochozka, Maroušková, & Šuleř, 2018). Consequently, we have also been witnessing major technological advances in renewable energy systems (Baranyai, Mosavi, Vajda, & Varkonyi-Koczy, 2017;Imani, Zalzar, Mosavi, & Shamshirband, 2018;Moeini, Ahmadpour, Mosavi, motivation to move towards using various types of solid wastes for the purpose of energy production (Dabe, Prasad, Vaidya, & Purohit, 2019;Lino & Ismail, 2018;Tiwary, Spasova, & Williams, 2019;Vuppaladadiyam, Zhao, Memon, Soomro, & Wei, 2019a, 2019b.…”

The main innovation of the study is the use of a novel energo-environmental approach for investigation of biogas production, and analysis of the amount of methane and biogas produced in terms of energy production and global warming potential (GWP). Two types of reactors (laboratory-scale and semi-industrial reactors) were prepared for biogas production to perform a detailed study and for exact consideration of treatments in terms of production. Based on the results, the maximum methane production in the laboratory-scale set-up was related to a carbon/nitrogen (C/N) ratio of 30 at mesophilic temperature (35,967 ml/kg volatile solids). Accordingly, the C/N ratio in the semiindustrial reactor was considered to be 30; methane production was equal to 14/489m3 at loading rates of 237.5, 2.580 and 234.92 kg for cow manure, wheat straw and water content, respectively. The maximum biogas production occurred on day 65, from the viewpoint of energetic analysis. The highest daily net electricity production occurred on day 12, with a positive energy balance. However, considering GWP effects in the production and use of biogas, it would be better to stop production on day 48, in which case methane production would be equal to 77% of the final limit of biogas production.

“…Uma das maneiras de tratar a água residuária é através da utilização de reatores anaeróbios de fluxo ascendente e manta de lodo -UASB (em inglês, Upflow Anaerobic Sludge Blanket), considerado um dos melhores processos de tratamento anaeróbio desenvolvidos até hoje (Stazi e Tomei, 2018). O uso destes reatores para tratamento do esgoto doméstico tem se tornado cada vez mais comum especialmente em paises na América Latina e Índia (Rosa et al, 2018). De acordo com Chernicharo (2006), o uso de reatores anaeróbios é uma tecnologia consolidada em países quentes como o Brasil, onde praticamente todos os estudos de viabilidade de tratamento de efluentes incluem reatores anaeróbios como uma das principais opções.…”

Com o crescimento demográfico intensificou-se os problemas ambientais em decorrência do aumento na geração de efluentes líquidos. Desta forma torna-se fundamental a busca por alternativas sustentáveis na redução dos impactos. Neste cenário o presente trabalho tem como objetivo analisar o potencial energético e a viabilidade econômica do aproveitamento de biogás gerado em reator UASB no tratamento de efluentes originados pelo Município de Itaúna-MG, possibilitando o planejamento energético no período de 2018 a 2038. Estimou-se a projeção da população para este período e o dimensionamento do reator conforme as projeções de efluentes lançados. A produção média calculada de metano e de energia total produzida foi de 1.899,4 m3.dia-1 e 39,3 GWh, respectivamente. O investimento total necessário foi de R$ 1.301.508,53, possibilitando a viabilidade econômica do projeto. A partir deste projeto é obtida a redução dos impactos ambientais consoante a geração de energia renovável.
