ABSTRACT:
Nowadays, the world is in a period of waste accumulation in large quantities. Many companies worldwide produce thousands of effluents whose alternative uses are still unclear. For example, vinasse is the most important liquid waste produced mainly by the distillery industry. However, several alternatives for vinasse management have emerged in recent years. The aim of this review was to collect information about the conventional and non-conventional technologies for vinasse management. The proposed methodology was to group the technologies according to two large groups: physical-chemical and biological processes. In many countries, fertigation of the sugarcane crops is one of the most applied technologies for sugarcane vinasse management. In addition, there are other technologies to address this problem such as: concentration by evaporation, combustion, livestock feed production, gasification, vermicomposting, yeast production, biogas production and recycling in fermentation. Thus, new studies and green non-conventional methods have been developed aiming at vinasse recycling. Some of them are membrane and electrochemical processes from a physical-chemical point of view and biohythane production, dark fermentation and bioremediation as biological alternatives.

Keywords: vinasse management, biological process, physicochemical process, conventional, non-conventional.
