Ethanol plays a crucial role in Brazilian and global contexts, serving as a viable and sustainable alternative to fossil fuels. Brazil stands out as a leader in ethanol production, particularly from sugarcane, thereby establishing itself as a benchmark in industrial sustainability. The country's large-scale production of this biofuel boosts the nat...

The demand for new products derived from agro-industrial residues has increased recently. Furthermore, vinasse, a wastewater from ethanol production, needs treatment to be reused in the sugarcane industry, reducing industrial water consumption. This study performed vinasse filtration with charcoal from industrial sugarcane residues and used the fil...

The industrial production of bioethanol takes place through the fermentation process by the action of selected yeasts in a favorable environment generated by the high concentration of sugar in the must. For the process to occur properly, it is essential to minimize the presence and action of microbial contaminants, which enter the process compromis...

A limitação das reservas mundiais de combustíveis fósseis, a instabilidade do preço desses combustíveis e a preocupação em diminuir as emissões de gases de efeito estufa, intensificaram o interesse em novas pesquisas em fontes de energia. Uma alternativa encontrada foi o incentivo ao uso do etanol, produzido de diversas fontes, como a cana-de-açúca...

The reuse of wastewater produced in industrial processes is important to contribute to reducing the use of water obtained from natural resources. Vinasse, one of the most important byproducts in ethanol production, could be reused in ethanolic fermentation. However, its use can cause problems during the fermentation process. This work aimed to eval...

O reuso das águas residuárias, produzidas nos processos industriais, contribui para reduzir a utilização de água de recursos naturais. A vinhaça, um dos subprodutos mais importantes na produção de etanol, poderia ser reutilizada na fermentação etanólica, no entanto, apresenta restrições por inibir as leveduras durante o processo fermentativo. O obj...

The traditional industrial fermentation process to obtain bioethanol takes place in a favorable environment not only for the action of yeast, but also for the development of undesirable microorganisms that end up compromising production by consuming the raw material, producing inhibitory substances, altering the ideal conditions. of the process, me...

Few studies address how to measure the impacts of the sugar-energy industry on the environment and human health. Thus, in this paper, an index (Iepa) to evaluate the impacts of the sugar-energy manufacturing process on the well-being of ecosystems and human society is proposed. The proposed index was developed from: (1) the environmental impact pot...

The generation of large volumes of vinasse during the production of biofuel ethanol is a challenging problem since inappropriate application of the byproduct as an agro-fertigant can give rise to contamination of soil and watercourses and cause harm to aquatic life. The aims of the study were(i) to evaluate an alternative strategy involving the gen...

Alcohol‐free beer with isotonic properties is getting more popular and its production can be carried out by different production strategies; however, interrupted fermentation is still a challenge. Therefore, the objective of this study was to develop a low‐alcohol isotonic beer (<0.5% v/v) by interrupted fermentation. Moreover, the major objective...

Understanding sugarcane ( Saccharum spp.) response to multiple pest injury, sugarcane borer ( Diatraea saccharalis ) and spittlebug ( Mahanarva fimbriolata ), is essential to make better management decisions. Moreover, the consequences of both pests on the sugarcane raw material quality have not yet been studied. A field experiment was performed in...

Despite the importance and characteristics sugar-energy industry, the specialized literature does not present studies to analyze specifically the human toxicity of residues and by-products generated by this industry. Therefore, the objective of this article is the proposal of an unprecedented Human Toxicity Potential Index (Htpi) applied to the sug...

Production of low alcohol craft beer by stopped fermentation

This article aims to analyze the environmental performance of the plants belonging to sugar energy plants of the River Mogi Guaçu Basin. With the identification of waste and byproducts generated at each stage of sugar and ethanol production process, were identified the potential impacts and carried out a quantitative estimation of the relative envi...

Resumo This study aim to compare the action of antimicrobials: hop extract, oregano essential oil (OEO) and chlorine dioxide during the fermentation process. For this purpose, three studies have been conducted. In the first two studies, control treatment, Kamoran® (3 mg L⁻¹), oregano oil (0.5%) and hop extract (10 mg L⁻¹) were used. In the third e...

O objetivo deste trabalho consiste em apresentar um estudo comparativo entre os metodos FMEA e HAZOP aplicados ao ambiente de fabricacao do bioetanol. O trabalho desenvolve, na forma de indicadores categoricos congruentes com a logica fundamental dos chamados “metodos de analise de causas raizes de problemas”, oito criterios com vistas ao confronto...

The sugarcane borer, Diatraea saccharalis (F.) (Lepidoptera: Crambidae), is a key pest of sugarcane (Saccharum spp.). While dam- age caused by this pest has increased in the past 20 yr, studies investigating the insect–plant interactions are still lacking. More- over, there is no information about the consequences of borer damage on the parameters...
