In this paper, we fill the gap in the literature by identifying a negative relationship between fuel ethanol consumption and CO2 emissions, building on a sample of 17 European countries covering seven years, from 2010 to 2016. Based on a Panel Smooth Transition Regression approach we show that countries with high levels of income inequality have difficulties in avoiding environmental degradation by promoting policies and regulations for more intense use of biofuels. Furthermore, we bring strong empirical evidence suggesting that biofuels could be an alternative in the future to reducing CO2 emissions. In our opinion, this non-linear analysis could provide the scientific basis for authorities, especially the European Commission to promote environmental policies to a specific country with different levels of carbon emissions rather than to the entire group.

“…[ 87] Corn and grain can be classified as starch-based materials. Their widespread use in biomass-to-ethanol processes [46,113] results in the availability of great amount of both corn-and grain-based stillage. Eskicioglu et al [103] evaluated the anaerobic potential of whole stillage from a dry-grind corn-based ethanol plant by continuous-flow digesters under both thermophilic and mesophilic conditions.…”

Abstract:In the last decades the increasing energy requirements along with the need to face the consequences of climate change have driven the search for renewable energy sources, in order to replace as much as possible the use of fossil fuels. In this context biomass has generated great interest as it can be converted into energy via several routes, including fermentation and anaerobic digestion. The former is the most common option to produce ethanol, which has been recognized as one of the leading candidates to substitute a large fraction of the liquid fuels produced from oil. As the economic competitiveness of bioethanol fermentation processes has to be enhanced in order to promote its wider implementation, the most recent trends are directed towards the use of fermentation by-products within anaerobic digestion. The integration of both fermentation and anaerobic digestion, in a biorefinery concept, would allow the production of ethanol along with that of biogas, which can be used to produce heat and electricity, thus improving the overall energy balance. This work aims at reviewing the main studies on the combination of both bioethanol and biogas production processes, in order to highlight the strength and weakness of the integrated treatment for industrial application.

“…Dentre os biocombustíveis de maior interesse econômico, o etanol vem se destacando há vários anos. Esse combustível é produzido, principalmente, a partir de matérias-primas açucaradas como o caldo extraído da cana-de-açúcar e o extrato da beterraba sacarina, bem como de biomassas amiláceas como milho, mandioca e trigo (PATNI et al, 2013). Nas últimas décadas as tendências sinalizam para o desenvolvimento de tecnologias alcooleiras que permitam o aproveitamento de resíduos agroindustriais e florestais, de modo sustentável (BALAT, 2011;LIMAYEM;RICKE, 2012;PEREIRA Jr. et al, 2008), pois , sabe-se que as culturas tradicionais, como milho e cana-de-açúcar não podem suprir demanda global de produção de bioetanol, devido ter em valor primário na alimentação humana e animal (SARKAR et al, 2012).…”

Composition, enzymatic saccharification and fermentability of jatropha cake for bioethanol production

et al. 2017

ResumoA torta de pinhão-manso (Jatropha curcas L.), coproduto do processo de obtenção do biodiesel, apresenta um percentual significativo de carboidratos poliméricos em sua composição. Uma estratégia atraente para o aproveitamento dessa biomassa seria a biotransformação de seus carboidratos para a produção de etanol. Nesse contexto, o presente estudo teve por objetivo avaliar a composição da torta de pinhão-manso, bem como promover a otimização do processo de sacarificação enzimática da fração amilácea contida na torta e avaliar, também, a fermentabilidade do hidrolizado enzimático para produção de bioetanol. O planejamento experimental utilizado seguiu um modelo Composto Central Rotacional (CCR), cujos fatores avaliados foram o tempo de hidrólise e a concentração de enzima amilolítica, resultando em rendimento hidrolítico de 90%. O processo fermentativo realizado com Saccharomyces cerevisiae e o hidrolisado amiláceo derivado da torta de pinhão-manso apresentou valores de eficiência fermentativa de 100%. O uso da torta de pinhão-manso para produção de bioetanol pode ser uma estratégia eficiente se associada à cadeia produtiva do biodiesel como forma de agregar valor a um coproduto abundante e como alternativa para produção de uma fonte de energia renovável.Palavras-chave: biomassa; etanol; fermentação; hidrólise; Jatropha curcas L.
