UNLABELLED BACKGROUND A modified laboratory-scale upflow anaerobic sludge blanket (UASB) reactor was used to obtain methane by treating hydrous ethanol vinasse. Vinasses or stillage are waste materials with high organic loads, and a complex composition resulting from the process of alcohol distillation. They must initially be treated with anaerobic processes due to their high organic loads. ...

In Brazil, the degradation of nutrient-poor Ferralsols limits productivity and drives agricultural expansion into pristine areas. However, returning agricultural residues to the soil in a stabilized form may offer opportunities for maintaining or improving soil quality, even under conditions that typically promote carbon loss. We examined the use of biochar made from filtercake (a byproduct of ...

Biogas production from sugarcane waste has large potential for energy generation, however, to enable the optimization of the anaerobic digestion (AD) process each substrate characteristic should be carefully evaluated. In this study, the kinetic challenges for biogas production from different types of sugarcane waste were assessed. Samples of vinasse, filter cake, bagasse, and straw were analyz...

BACKGROUND During hydrous ethanol production from the sugar refinery industry in Mexico, vinasse is generated. Phenolic compounds and melanoidins contribute to its color and make degradation of the vinasse a difficult task. Although anaerobic digestion (AD) is feasible for vinasse treatment, the presence of recalcitrant compounds can be toxic or inhibitory for anaerobic microorganism. Therefore...

This research aims is the agroindustrial wastewater treatment by an electrochemical device called Microbial Fuel Cell (MFC), which produces electricity while to metabolize the wastewater. The behavior of biofilme formed at reticulated carbon vitreous/Shewanella putrefaciens/vinasse solution interface as anode, was studied by electrochemical measurements. The polarization curves against the carb...

Vinasse that has high COD and total solid content is bottom of distillation from unit of bioethanol production Vinasse treatment using anaerobic digestion produced biogas. This research used anaerobic digester-laboratory scale at room temperature and batch system. The purpose of this research was investigation the effect of total solid content to biogas production rate from vinasse, pH profil a...

This article presented an innovative data of feasibility to produce Arachidonic acid (ARA), as added-value Polyunsaturated Fatty Acids (PUFA), among other lipids from Mortierella elongata, using simulated low cost sugarcane wastewater, vinasse, as a carbon source. Data from lipids quantification by total lipids extraction and by lipid classes was presented. M. elongata was able to produce 156.4...

The application of fresh vinasse waste is still controvertion. objective this research was to determine the effect doses given on land chemical characteristics for soil quality. It conducted in a randomized block design with 4 3 replications. There were kinds doses, namely 75,000, 150,000, 225,000 and 300,000 litres/ha. control administration 0 litre vinasse, which sampling carried out at begin...
