“…A summary of vinasse composition is presented in Table 1. Sugarcane vinasse is reported to be a nitrogen-deficient medium, which is most composed as acid-insoluble nitrogen (Parnaudeau et al, 2008). Vinasse is also characterized as a feedstock rich in phenolic compounds and melanoidins (FitzGibbon et al, 1998).…”

Vinasse from Sugarcane Ethanol Production: Better Treatment or Better Utilization?

Ethanol production from sugarcane in Brazil is a well-established industry, with relatively simple operations and high yield. The ethanol primarily serves as a renewable fuel blending with gasoline and diesel to increase the energy security in Brazil. Several environmental concerns are emerged around the by-products from this industry. Vinasse, the liquid fraction generated from the rectification and distillation operations of ethanol, is a sulfur-rich, low pH, dark-colored, and odorous effluent, produced at volumes as high as 20-fold of ethanol. Traditional wastewater treatments, such as bioprocessing, advanced oxidative processes, anaerobic digestion (AD), and chemical-based processes, have been applied to vinasse management. Despite most of its utilization being in fertirrigation practices, vinasse may represent a key factor in enhancing profitability and environmental outcomes of a sugarcane-to-ethanol plant. The application of some upgrade solutions to sugarcane-derived vinasse may represent additional sources of energy, production of animal feed components, and reduction in water consumption within a plant. The use of mature technologies, yet not widespread in the sugarcane-to-ethanol industry, could help attenuate environmental concerns. Oxidation and chemical processes, AD, and microbial fermentation have been presented as alternative impactful alternatives to (i) reduce its organic and mineral load, converting it to a feedstock with fewer environmental applications when applied as fertilizer and (ii) to convert organic matter and nutrients to a nutritious biomass, simultaneously increasing water reclamation potential by plants. This mini-review article provides a critical and comprehensive summary of the alternatives developed or under development to vinasse management.

“…Diduga asam karboksilat yang dihasilkan adalah dalam bentuk endapan, namun ada kemungkinan juga asam karboksilat yang dihasilkan terikut di dalam filtrat. Seperti yang dikemukakan oleh Parnaudeu dkk [7], bahwa tidak semua asam hasil hidrolisis akan berada dalam fase padatan, karena sebagian akan tetap berada dalam fase cairnya. Oleh karena itulah, pengujian gugus pada kedua zat ini sekaligus dimaksudkan untuk membandingkan banyaknya asam dan jenis asam yang terdapat pada kedua zat (endapan dan filtrat hasil hidrolisis) melalui pengecekan gugus fungsi.…”

Optimasi Proses Hidrolisis Vinasse Sebagai Bahan Baku Resin Polimer yang Ramah Lingkungan

Vinasse contains some amine, carboxyl and hydroxyl groups in its organic acids. Keywords: vinasse, polymer resin, hydrolysis, coating material PendahuluanResin sintetik seperti phenolic resin, epoxy resin ataupun perpaduan dari keduanya (phenolic-epoxy resin) adalah salah satu contoh polymer resin yang telah lama digunakan sebagai material coating, baik untuk coating furniture, circuit boards maupun untuk coating logam. Hanya saja, resin-resin sintetik umumnya masih mempunyai beberapa kekurangan, antara lain bahan bakunya yang terbatas, bersifat racun, tahan lama dan diperburuk dengan sifatnya yang sukar terdegradasi. Oleh karena itu, maka penelitian-penelitian baru untuk memproduksi polimer resin yang lebih ramah lingkungan sangat diperlukan. Vinasse adalah bahan baku utama yang diharapkan dapat digunakan sebagai bahan coating material.

“…Vinasse, a residue from the sugar-alcohol industry applied to the soil in fertigation of reeds, has a high content of dissolved organic matter, ranging from 10,973 and 14,801 mg L -1 (Benke et al, 1999), and a high capacity of proton donation (Parnaudeau et al, 2008). The incorporation of vinasse to the soil may increase the amount of dissolved organic carbon and change the cations saturation in the soil solution, which directly or indirectly affects the sorption mechanisms (Fernández-Bayo, 2009).…”

Vinasse Effect on Herbicides Clomazone and Tebuthiuron Availability in Different Kinds of Soils

et al. 2015

-The objective of this study was to evaluate the availability of herbicides clomazone and tebuthiuron in the solution in different kinds of soils saturated with water or vinasse. Samples of 30 soils with different characteristics were arranged on trays to the herbicides spraying. Then they were homogenized, placed in plastic cartridges and saturated with deionized water or vinasse, and remaining at rest during 18 hours. Two extractions were made, the first one quantified the presence of the herbicides in the soil solution and in the second one the total extraction of herbicide remaining in the soil was taken to determine the recovery percentage of each herbicide tested. For quantification, a LC-MS/MS system was used, a compound of a high performance liquid chromatograph (HPLC) coupled to a triple quadruple mass spectrometer. Tebuthiuron was more available in the soil with the vinasse addition when compared to water. Vinasse applications resulted in no significant difference in availability of clomazone between treatments. Tebuthiuron showed the highest availability frequencies, and on average of all samples 32.49% were extracted from total herbicide applied, while for clomazone this value was 16.50%.Keywords: sugarcane, mass spectrometry, HPLC, sorption. Palavras-chave: cana-de-açúcar, espectrometria de massas, CLAE, sorção. RESUMO -O objetivo deste estudo foi avaliar a disponibilidade dos herbicidas clomazone e tebuthiuron
