“…In Brazil, stillage is mainly used as fertilizer [12] and both dilute and concentrated stillage can be spread on agricultural fields [13]. However, the long-term consequences of such application are not well established [12][13][14][15][16][17]. Gouvêa de Godoi et al [18] have recommended stillage treatment before its use as fertilizer in order to reduce the environmental impact of this practice.…”

“…Another approach extensively studied for stillage disposal is its concentration. Thermal concentration by evaporation [30] and concentration by reverse osmosis (RO) [17] are the technologies that have been used to concentrate stillage. Peiter et al [24] recently compared reverse osmosis, evaporation and forward osmosis for the concentration of an anaerobic biodigested stillage.…”

Direct contact membrane distillation (DCMD) was evaluated as an alternative for the treatment of sugarcane stillage obtained in the bioethanol production process. First, a synthetic stillage solution was prepared in order to study the influence of the main operational parameters of DCMD in the permeate flux, as well as to analyze the separation of volatile components (such as ethanol and acetic acid) and the concentration of non-volatile components presented in the feed stream (sucrose and other salts). Secondly, an industrial sample of sugarcane stillage was treated using DCMD. The highest flux achieved was 13.4 kg/m 2 •h for a transmembrane temperature difference of 55 °C, reaching a recovery degree of 70% with a specific thermal energy consumption of 671 kWh/m 3 . Then, sugarcane stillage was concentrated until 60°Brix. A preliminary economic study was also presented, an estimated cost of 1.25 $ per m 3 of recovered permeate was obtained without any heat integration or DCMD operational optimization. DCMD showed to be suitable for stillage disposal allowing to recuperate the permeate stream as process water (containing mainly water and a low concentration of volatile components) and the concentrated stillage as biofuel to be used in the steam boiler (for producing more energy making the process thermally sustainable) or for ferti-irrigation (for reducing the transportation cost due to the volume reduction).

“…As it can be observed, physicochemical parameters of both samples (V 2017 and V 2018 ) were signi cantly different between them. This variability depends on the sugar cane variety and maturation, the substrate used in fermentation, distillation, and sul tation process that enriches the downstream products with sulfur compounds especially sulfate species(de Godoi et al 2019). This wide range of physicochemical properties represents a challenge to use vinasse as carbon source on PHA production.…”

This work aimed to study the feasibility to use vinasse for polyhydroxybutyrate (PHB) production by Bacillus megaterium. To optimize the culture medium, a Box Behnken design was employed considering carbon (C), nitrogen (N), and phosphorus (Ph) concentrations as independent variables and PHB productivity as the response variable. The productivity decreased when C or N were increased, probably due to the presence of phenolic compounds and the limitation of N for the production of PHB by Bacillus sp. bacteria. An additional experimental design to optimize the C/N ratio and growing conditions (fermentation time and temperature) was carried out. Fermentation time had a statistically significant effect on PHB productivity reaching 10.6 mg/L h. On the other hand, the variability in physicochemical properties of vinasse samples led to significant differences in PHB productivity. Lower productivity values were obtained when vinasse had DBO high values. Therefore, biopolymers production from vinasse is a feasible alternative to valorize this bioethanol by-product.

“…Dados presentes da literatura indicam uma produção de 10 a 15 L de vinhaça a cada 1 L de etanol. Em termos gerais, a vinhaça é um efluente de cor escura, apresenta elevada concentração de matéria orgânica, assim como de potássio e sulfato, elevada cor e salinidade, características ácidas e corrosivas, e elevada temperatura, aproximadamente 85-90°C (CRAVEIRO, SOARES, SCHMIDELL, 1986;SALOMON, LORA, 2009;ESPAÑA-GAMBOA et al, 2011;DE GODOI et al, 2019).…”

“…Na Tabela 1 são apresentados alguns parâmetros físico-químicos da vinhaça de acordo com a literatura de referência. Vale ressalvar a presença de glicerol como importante constituinte da vinhaça, advindos do processo de fermentação do caldo e/ou do melaço, em concentrações de 0,3 a 5,4 g L -1 (DOWD et al, 1994;BONINI, 2012;DE GODOI et al, 2019), responsável pela escolha do glicerol como cossubstrato na codigestão anaeróbia da vinhaça nesta pesquisa, conforme abordado nas seções seguintes. Na etapa de fermentação, no processo produtivo do biocombustível, a adição de ácido sulfúrico resulta na característica ácida do efluente, com variações de pH entre 3,5 e 5,0.…”
