“…Additional technological approaches proposed for the management of vinasse include the cultivation of microbial biomass for the production of protein-rich cells (Pires et al, 2016;Santos et al, 2016), which may also be coupled to the recovery of different bioproducts, such as bioemulsifiers (Colin et al, 2016;Oliveira and Garcia-Cruz, 2013), enzymes (Kahraman and Gurdal, 2002), and lipids (Fernandes et al, 2017). The recycling of vinasse into the fermentation step has also been shown as an efficient destination for this HSW, aiming at the production of fuel ethanol (Navarro et al, 2000) and spirits (Menezes et al, 2013).…”

Sugarcane vinasse has been widely used as a soil fertilizer in the Brazilian sucro-alcohol industry for recycling potassium and water. However, the potential negative effects from long-term soil fertirrigation represent a major drawback regarding this practice, whereas the application of biodigestion represents an efficient method for reducing the polluting organic load and recovering bioenergy from vinasse. Regardless of the predicted use for vinasse, an understanding of the potential of each option is imperative, as the seasonal alterations in the inorganic/organic fractions of vinasse directly affect its management. In this context, this study presents a detailed compositional characterization of sugarcane vinasse from a large-scale Brazilian biorefinery throughout the 2014/2015 harvest to assess the environmental effects (due to fertirrigation) and to estimate the biogas energetic potential. Calculated inputs of organic matter into soils due to vinasse land application were equivalent to the polluting load of populations (117-257inhabha) at least 2-fold greater than the largest Brazilian capital cities (78-70inhabha). Two-phase biodigestion could efficiently reduce the polluting load of vinasse (23-52inhabha) and eliminate the negative effects from direct sulfide emissions in the environment. However, a high risk of soil sodification could result from using high doses of Na-based alkalizing compounds in biodigestion plants. Finally, the optimized recovery of bioenergy through biogas (13.3-26.7MW as electricity) could supply populations as large as 305 thousand inhabitants, so that over 30% of the surplus electricity produced by the studied biorefinery could be obtained from biogas. Overall, applying biodigestion in the treatment of vinasse provides important environmental and energetic gains. However, the benefits of reducing the polluting organic load of vinasse through bioenergy recovery may lose their effect depending on the alkalizing strategy, indicating that the proper use of chemicals in full-scale biodigestion plants is imperative to attain process sustainability.

Molasses is a by-product from the raw sugarcane industry with vast applications in the production of ethanol biofuel. A good knowledge of the rheological properties of this raw material is of crucial importance when designing and optimizing unit operations involved in processing it. The present work thus aims to study the rheological behavior of molasses at solid concentrations ranging from 20 to 70 o Brix and temperatures between 21 and 988C using a concentriccylinder rheometer. Experimental results showed Newtonian behavior in concentrations of 20 and 40 o Brix and pseudoplastic behavior in concentrations of 50 and 70 o Brix. For these results, the Power Law models presented the best fitting results. In addition, the dependence of the flow behavior index and the flow consistency index of the Power Law model on temperature and solid concentration was also successfully modeled through a polynomial model and an Arrhenius-type equation, respectively.

“…Although the historical, cultural and economic context of cachaça, its production is related to several environmental problems especially related to effluents and residues (Menezes, Alves, Valeriano, & Guimarães, 2013;Rosa & Martins, 2013). Vinasse, the main residue originated from distillation, is produced in concentrations ranging from 8 to 10 liters per liter of product (Oliveira, Andrade, Faria, Evangelista, & Morais, 2009), characterized as an acidic suspension, with high chemical oxygen demand, dark brown color and unpleasant odors (Jiang et al, 2012;Christofoletti, Escher, Correia, Marinho & Fontanetti, 2013).…”

Vinasse is the main waste of the productive activity of fermentative processes for ethanol and cachaça production due to the large volume generated, but little is known about the composition of vinasse from alembic cachaça. The present study evaluated the influence of the sugarcane variety (RB867515, RB966928 and RB855453) and management (conventional and organic) on the mineral composition of vinasse from alembic cachaça in a randomized block design with four parcels. Vinasse samples were evaluated for pH and concentrations of carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, copper, manganese and zinc and carbon/ntrogen ratio. There was a significant effect of management only on three elements of the vinasse composition, C, K and Mg. Regarding the variety, there was a significant effect only on Ca and Mg concentrations in the varieties RB867515 and RB855453. The sugarcane variety and management had little influence on the composition of vinasse from alembic cachaça. The average concentration of macro-and micronutrients of the vinasse samples indicates that it can be used in fertigation due to the rich composition in macro-and micronutrients when compared to the cachaça or ethanol vinasse compositions reported in literature, especially N, P, K, Ca, Mg, S, Fe and Cu.Influência do manejo e da variedade de cana-de-açúcar sobre a composição mineral da vinhaça de cachaça de alambique RESUMO. A vinhaça é o principal resíduo da atividade produtiva dos processos fermentativos para a produção de etanol e cachaça devido ao volume gerado, no entanto pouco se conhece sobre a composição da vinhaça de cachaça de alambique. O presente trabalho avaliou a influência do manejo (convencional e orgânico) e da variedade (RB867515, RB966928 e RB855453) sobre a composição mineral da vinhaça de cachaça de alambique em experimento com blocos ao acaso com quatro parcelas. As amostras de vinhaça foram avaliadas quanto ao pH e concentrações de carbono, nitrogênio, fósforo, potássio, cálcio, magnésio, enxofre, ferro, cobre, manganês e zinco, e relação C/N. Houve efeito significativo do manejo somente sobre a concentração de três nutrientes da composição da vinhaça: C, K e Mg. Em relação à variedade, houve efeito significativo somente nos teores de Ca e Mg nas variedades RB867515 e RB855453. O manejo da cana e a variedade tiveram pouco efeito sobre a composição da vinhaça de cachaça de alambique. A concentração média de macro e micronutrientes das amostras de vinhaça de cachaça de alambique a torna fortemente recomendável para uso em fertirrigação devido à composição rica em macro e micronutrientes quando comparada à composição da vinhaça de cachaça ou de bioetanol relatada na literatura, destacando-se N,
