Sugarcane vinasse (SV) is the main by-product of bioethanol production. It is considered a potential pollutant due to its acidity index and the presence of organic components, suspended solids and heavy metals. High levels of SV production are undoubtedly a threat to the environment and the community in general. The aim of this study was to evaluate the main SV dispositions or treatments, in addition to their applications, by using bibliometric maps for metadata analysis. It was found that the studies related to SV were focused in (i) anaerobic digestion (AD), (ii) fertirrigation, (iii) coagulation/flocculation, (iv) algae, microalgae and fungi, and (v) biohydrogen production. Additionally, it was determined that the most effective treatment for SV was AD, reaching 90% chemical oxygen demand removal efficiency and energy recovery between 85 and 95% as biogas. Finally, the challenges and opportunities facing Latin America with the growing production of SV were addressed, as well as a detailed review of its treatment and/or disposal, including optimal conditions for the production of value-added products.

Keywords : sugarcane vinasse; anaerobic digestion; fertirrigation; coagulation/flocculation; biohydrogen; bibliometric analysis.
