“…(1) ), with an efficiency of 38%, reaches 0.0028 MWh/m 3 of vinasse. This value is 20% lower than that obtained by Silva dos Santos et al (2018) , and equal to the result reported by Moraes et al (2014) . Vinasse production from the ethanol production process, estimated as 15 L per each liter of ethanol produced, for the sugarcane crop area in ARC, São Paulo, Brazil (513,123.30 ha for 2017/18 harvest season), accounted for 2.38 × 10 7 m 3 /year, for the assumption yield of 85 L of ethanol per ton of milled sugarcane.…”

This study evaluates the benefits of mineral fertilizers replacement for biodigested vinasse. Data from experimental anaerobic digestion (AD) of vinasse were applied to support the analysis. Based on previous experiments, this assessment assumed that vinasse production could reach 2.38 × 10 7 m 3 /year generating around 66,585 MWh/year of electric energy from biogas burning in the Administrative Region of Campinas (ARC). This amount of energy could supply more than 103,000 inhabitants and avoid 35,892 tCO 2eq /year (from electric energy replacement). The biodigested vinasse might also reduce the total N, P, and K mineral fertilizers demand per hectare of sugarcane crop in 30%, 1%, and 46%, respectively, avoiding additional greenhouse gas emissions of 111,877 tCO 2 eq/year. There is no biodigested vinasse surplus for a moderate fertigation rate of 100 m 3 /ha, complying with local environmental laws related to nutrients excess side effects in areas destined to sugarcane crop. Notwithstanding, a Geographic Information System analysis for a small adjacent area to ARC indicated nine different fertigation rates, ranging from 50 to 100 m 3 /ha. Even though the general analysis for ARC shows high NPK replacement levels, the fertigation practices should be subsidized for robust soil analysis and adequate to safe environmental levels. A management tool can be designed using the results here presented to subsidize investments for AD widespread adoption by the sugarcane industry to catch a reasonable practice from the economic and environmental perspectives.

“…The authors found a maximum landfill biogas installed capacity of 1.2 GW by 2045. Silva dos Santos et al [10] projected a biogas power installed capacity potential between 4.5 and 6.9 GW, considering cattle manure as the largest untapped potential for biogas production (around 170 mcm/day or 3.8 GW).…”

Modelling cost-effective pathways for natural gas infrastructure: A southern Brazil case study

Currently, natural gas in Brazil represents around 12.9% of the primary energy supply, with consistent annual growth during the last decade. However, Brazil is entering a time of uncertainty regarding future gas supply, mainly as import from Bolivia is being renegotiated. As such, diversification of gas supply sources and routes need to be considered. Energy systems and infrastructure models are essential tools in assisting energy planning decisions and policy programmes at regional and international levels. In this study, a novel combination of a simulationbased integrated assessment model (MUSE-South_Brazil) and the recently-developed Gas INfrastructure Optimisation model (GINO) is presented. The Brazilian region represented by the five southern states served by the Bolivian gas pipeline (GASBOL) has been investigated. Modelled projections suggest that regional gas demand would increase from 38.8 mcm/day in 2015 to 104.3 mcm/day by 2050, mainly driven by the increasing demand in the industry and power sectors. Therefore existing regional gas infrastructure would be insufficient to cover future demands. Three different renegotiation scenarios between Brazil and Bolivia were modelled, obtaining distinct costoptimal infrastructure expansion pathways. Depending on the scenario, the model expects gas demand to be covered by other supply options, such as an increase in pre-salt production, LNG imports and imports from a new Argentinian pipeline.

“…É importante salientar o papel da Resolução Normativa nº 482/2012 (ANEEL, 2012) e sua revisão, a Resolução Normativa nº 687/2015 (ANEEL, 2015). De acordo com as resoluções, a energia ativa injetada pela unidade consumidora com microgeração ou minigeração distribuída pode se converter em créditos junto à distribuidora local, sendo posteriormente compensada com o consumo de energia elétrica pelo sistema (Pin et al, 2018;Santos et al, 2018), uma vez que a venda pela tarifa do mercado cativo não seria capaz de viabilizar o empreendimento. Dessa maneira, o contexto de aplicação das resoluções atua como instrumento fundamental de auxílio na viabilidade deste tipo de empreendimento.…”

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.
