“…Generally, the most commonly used alcohol in transesterification reactions is methanol, since it has some advantages over ethanol, such as easier separation of biodiesel and glycerol, and lower cost in most countries [8,9]. However, Brazil is the leading producer of ethanol from sugarcane, and therefore, ethanol is cheaper than methanol because of the large volume of production [10][11][12]. Allied to this, ethanol is obtained from a clean source, and so it is environmentally friendly to reactions which ethanol is used [13,14].…”

“…The municipality of Sete Quedas has a characteristic focused on agribusiness, its activities in cattle ranching. Thus, the selection of distributed energy generation projects based on biomass can enhance the region's economy, integrating agricultural and livestock production without the need for more land to increase the region's productivity [58].…”

This article aims to propose a multi-criteria model to support decision-making from a portfolio in selecting technologies for Distributed Generation of Energy (DGE) projects based on the characteristics of the geographic space in Brazil. The decision model involves using multi-criteria to support the evaluation, prioritization, and selection of projects under a multistage decision-making process that fits into a strategic management cycle within the energy sector of Mato Grosso do Sul (Brazil). The over-classification techniques Preference Ranking Organization Technique for Enrichment Evaluations (PROMETHEE) II and V were applied under the Value-Focused Thinking (VFT) approach, reflecting the decision-maker or manager preferences among several conflicting criteria in the investment context of sustainable distributed energy generation projects. Based on real data, a numerical application is employed to view the steps of this decision model and illustrate the adequacy and effectiveness in practical issues of portfolio management.

“…Besides, economic allocation had only up to 3% change compared to energetic allocation. There are other possible uses of sugarcane lignocellulosic material (i.e., bagasse and straw), such as in the second-generation ethanol production (Junqueira et al, 2017), in thermochemical pathways for biofuel and bioenergy production (Bressanin et al, 2020(Bressanin et al, , 2021, and as animal feed (Souza et al, 2019;2021b), among others. Other LCA modeling approaches for handling residues and coproducts such as the consequential approach could also lead to interesting insights (Heimersson et al, 2019;Schaubroeck et al, 2021).…”

The implications of bioenergy deployment for sustainable development goals (SDGs) have been gaining importance worldwide, as bioenergy may contribute to other sustainability impacts besides climate change. Decarbonization of the energy sector can promote major co-benefits between Climate Action and other SDGs and lead to important tradeoffs. Life cycle assessment (LCA) methods have been proposed to monitor the SDGs as many of them are closely interconnected but often separately studied.A harmonized application of environmental and social LCA can reveal additional relevant aspects of SDGs. This work proposes an interpretation of combined environmental and socioeconomic LCA impacts by comparing the SDG impacts of electricity from sugarcane biomass with other technological options, which altogether represent 96% of the Brazilian electricity matrix. Our analysis indicates that sugarcane electricity has a higher SDGs score (58 points) compared to coal and oil electricity (42 and 47 points, respectively); however, it is lower than natural gas (78). Sugarcane SDG internal normalization related to the biosphere is very close to natural gas, varying only 3-4 points.On the Economy and Society SDG score, sugarcane electricity is also lower than natural gas. Key areas in sugarcane electricity production that need to be enhanced to better contribute to achieving the SDGs include improving its awareness levels, increasing wages and women representation on the workforce, and promoting measures to decrease work accidents as well as the use of fertilizers and pesticides. This approach may help design specific measures for different value chains for them to significantly contribute to the achievement of SDGs.
