“…For example, the existence of a given shock in a market, even a local shock, will affect prices in the other market. Finally, policies related to tariffs or to change export quotas, which have been the subject of recent negotiations, tend to affect the speed of price alignment (Castañeda‐Ayarza and Godoi, 2020) 14 …”

“…Despite the importance of both countries in the global supply of ethanol, recent studies have focused only on their local markets, analyzing the dynamics of ethanol prices 7–12 . Ethanol markets in Brazil and the USA are interconnected due to trade (Debnath et al ., 13 2017), and 90% of imported Brazilian ethanol comes from the USA (Castañeda‐Ayarza and Godoi, 14 2020), implying that deeper analysis of the topic is relevant, to understand the connections between the markets.…”

Two different fractal regression methodologies were employed with the aim of understanding the relationship between prices of ethanol produced in the USA and Brazil, the most important producers of ethanol. These methodologies, which have the advantage of giving us information about the relationships between different timescales, could also provide interesting and important information about this particular market. Our results suggest, first, some differences in the basic price in these markets, and second, a positive relationship between prices (as expected) but not a one‐to‐one relationship. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…During the 1990s, the US government had mentioned methanol used under Clean Air Amendment Act 9 ; similarly, the Chinese government's effort and support resulted in it becoming the world's largest producer of methanol. 10 The government of India has promoted the production and use of green methanol through crops of farmers. 11 A similar effort has been made to promote ethanol by the government of India recently, which cleared policies related to ethanol to get 20% blending till 2025.…”

Alcohols are oxygenated renewable fuels responsible for low carbon emission and high H/C ratio. In the present study, a blend of methanol, ethanol, and n-butanol in equal proportion by volume (E-MEBANOL) is tested as a sustainable fuel for SI engines under variable compression ratio (CR) and ignition timing (SOI). The performance of the engine is found to improve by increasing CR as well as advancing the SOI, as the brake power (BP), brake thermal efficiency (BTE), and volumetric efficiency are found to increase by increasing CR to 15 from 11 at an advanced SOI of 24°CA before top dead center (BTDC) from 16°CA BTDC by 17.54%, 17.47%, and 10.53% respectively. Similarly, combustion is also enhanced with increasing CR and advancing SOI as the peak cylinder pressure (Pmax), and maximum net heat release rate (NHRmax) are found to increase by 60% and 27.64%, respectively, while positions of these peaks are advanced by 17°CA and 18°CA respectively by increasing CR from 11 to 15 and SOI advanced to 24°CA BTDC. The flame development period (CA10) increases with advancing SOI and decreases with increasing CR, while the flame development period (CA10-90) and total combustion duration decrease with both increasing CR and advancing SOI. The CO & HC emissions improve with increasing CR and advancing SOI, while NOx increases drastically, but EGT decreases continuously.

“…Os processos industriais, e, sobretudo, o alto consumo de combustíveis fósseis foram apontados como principais responsáveis pela emissão de gases de efeito estufa (GEE). Aliados aos problemas climáticos, o esgotamento das fontes tradicionais não renováveis de energia e a instabilidade no preço do petróleo preocupa os mercados globais e impulsiona buscas constantes por fontes alternativas e renováveis de energia que atendam a demanda mundial (CASTAÑEDA-AYARZA; GODOI, 2021;DIAS et al, 2018;RAJESH BANU et al, 2021;VIEIRA et al, 2020).…”

“…Atualmente no mercado mundial, Brasil e Estados Unidos ocupam posições de destaque no campo da produção de biocombustíveis, em 2017 produziram 60 e 27 milhões de m³ de etanol representando 85% da produção mundial e 75% do consumo de etanol. Em 2019, foram produzidos mundialmente aproximadamente 125 milhões de m³ de etanol e estima-se que em 2024 a produção chegará a 134 milhões de m³ (CASTAÑEDA-AYARZA; GODOI, 2021;HOARAU et al, 2018).…”

ResumoO consumo de recursos fósseis visando a geração de energia intensifica a emissão de gases de efeito estufa (GEE), que por sua vez pressionam negativamente as mudanças climáticas globais. Diante da urgente necessidade de redução de emissões de GEE, utilizar combustíveis de fontes renováveis e menos poluentes é uma alternativa viável sob os pontos de vista ambiental, econômico e energético. No Brasil, o principal biocombustível produzido é o etanol de cana-de-açúcar. Contudo, neste processo é gerada a vinhaça, um subproduto que devido à alta carga orgânica, concentração de nutrientes e acidez tem grande potencial poluidor. Com o objetivo de elencar as possibilidades de uso da vinhaça foi feita uma revisão bibliográfica integrativa, considerando, após pré-seleção, 19 achados primários voltados à aplicação da vinhaça como insumo. Como conclusão foram elencados a digestão anaeróbia visando a obtenção de biogás, a utilização como fonte de nutrientes para o desenvolvimento de organismos e posterior extração de biomassa, ácidos orgânicos, álcoois e enzimas, assim como a tradicional aplicação in natura como fertilizante e suas variantes.
