Abstract
The purpose of this study is to analyse the energetic potential of the vinasse coming from the distillation of rum. 10 to 15 l of vinasse are obtained for each unit of alcohol. This is being used as fertilizer for the cultivation of sugar cane. Three samples are analysed for physical, chemical and fuel properties: raw vinasse, its distillate and residue. The results demonstrated that raw vinasse can be used as an additive to liquid fuels with a calorific value of approximately 792 kJ/kg and a boiling point above that of flammability, which flavours the non-formation of vapours. The amount of solid waste present could be detrimental to atomization inside furnaces or its flow through combustion chambers, so it must be pre-treated.
Highlights
The decarbonisation of the electricity production sector [1] and the energy transition [2] in the search for achieving the millennium goals [3], have encouraged to explore new renewable energy sources and the use of biofuels that produce less environmental impact

Summary
The decarbonisation of the electricity production sector [1] and the energy transition [2] in the search for achieving the millennium goals [3], have encouraged to explore new renewable energy sources and the use of biofuels that produce less environmental impact. One of the options for its production is from industrial organic waste [5], among these, the vinasse from the manufacture of rum [6]. The raw alcohol is obtained, as well as other by-products, such as vinasse. The Vinasse is considered as a waste, and is discarded as it is not useful for the distilleries. This material contains a large organic load that can become a contaminant if not properly treated, and is used for irrigation or fertilization of some crops [7]. The present study shows the results of the physical, chemical and energy potential analysis of vinasse as a by-product of rum manufacturing.
