“…Methanobacterium and Methanosaeta drive the treatment of vinasse and methane production, so the metabolic pathways used are hydrogenotrophic and acetoclastic [139]. In Kiani Deh Kiani et al [140], the authors report that biogas production from vinasse is possible using a static granular bed reactor.…”

Vinasse is a toxic pollutant if it is poured into the ecosystem indiscriminately; despite this, it integrates components that make it valuable in nutrients and water. However, its use has been questioned due to the costs involved in its purification. This systematic review focuses on the valorization of vinasse from the studies performed for its post-industrial use. Trends in vinasse management and bioproduct development were analyzed. The PRISMA statement was used as a formal guide for collecting and analyzing 131 studies from 2018 to 2022. We determined that biological processes are the most used to obtain the benefits of vinasse, obtaining up to three post-industrial bioproducts. While it is true that there is a predominant trend of studies focused on the generation of biofuels, it must be noted that the beginning of the sucro-alcohol chain was the agricultural field. In this sense, we determine that 14% of the studies treat vinasse for agricultural reuse purposes, so, under Circular Economy principles, the reincorporation of vinasse into the agricultural field to take advantage of its goodness in nutrients and minerals as a sustainable and eco-efficient alternative should be a research trend that accelerates the consumption of vinasse generated in alcohol distilleries.

Sugarcane vinasse has been widely reported due to the improper management that pollutes the environment. In this study, a combined coagulation and sequencing batch bio lm reactor (SBBR) seems to be a novel improvement for the treatment of sugarcane vinasse. This research focused on the optimal conditions of coagulation and SBBR and determined the abatement e ciency of sugarcane vinasse in combined sequential wastewater treatment. The coagulation process destabilizes the colloids in the aggregation and separates the supernatant by sedimentation and ltration, resulting in the maximum COD reduction (79.0 ± 3.4%) and decolorization e ciency (94.1 ± 1.9%) under the optimum conditions. Sequencing batch reactor (SBR) is a ll-and-draw activated sludge system, whereas SBBR is an integrated SBR that suspends activated sludge and connects growth processes into a biocarrier-lled system. SBBR showed great synergistic degradability, decreasing 86.6 ± 4.3% COD concentration and 94.6 ± 3.8% decolorization at 3.0 g/L of substrate loading concentration. Furthermore, kinetic studies of SBBR revealed that the rst-order kinetic model was the best tting model. The SBBR reaction was further investigated by ultraviolet-visible spectrophotometry (UV-Vis). Then, SBBR followed by the coagulation process (SBBR-CP) achieved 97.5% of COD reduction and 99.4% of decolorization, which was better than the coagulation process followed by SBBR (CP-SBBR). This nding provides new insight into developing e cient combined sequential wastewater treatments in sugarcane vinasse.
