“…As of May 2022, we have collected 10 studies. In Tamashiro et al [13], it was concluded that sugarcane vinasse's wastewater as an additive in the manufacture of concrete in replacement of water creates more excellent resistance to compression. In Hashemi et al [146], the authors cultivated a first-stage Neurospora intermedia in wastewater from sugarcane vinasse and cheese whey; in a second stage, the effluent from the mushroom culture was di-gested anaerobically to produce biomethane, thus having treated vinasse.…”

“…However, the incorporation of vinasse excessively into the soil modifies the pH and conductivity, causing toxicity to the environment where it is poured [11], approximately 100 times more than domestic wastewater [8]. It is estimated that for each liter of ethanol, 10 to 15 L of vinasse are produced [5,12], from 12 to 18 L [13], about 12 L [14,15]; 15 L [16], or from 9 to 14 L [17], depending on the use or not of a recirculation process in the distillery, the richness of sugars in molasses, the quality of the fermented must, and the operating conditions in the distillation columns, among other factors. Of these studies, 85.71% consider within their estimate that 12 L are generated from vinasse for each liter of ethanol (see Figure 2).…”

Post-Industrial Use of Sugarcane Ethanol Vinasse: A Systematic Review

et al. 2022

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.
