Summary:The present work has as goal to evaluate prospectively alternative of transformation in the "5 de Septiembre" sugar industry, located in Cienfuegos, for a superfine alcohol biorefinery. Two alternatives were taking into account; the first one was the installation of a distillery for a capacity of 500 hl/d of superfine alcohol, using the molasses and 10% of the filters juice coming from the sugar mill, as complement of the stage of fermentation, and also a plant of biodiesel production starting from microalgae biomass and of mud separated in the sugar mill and another installation of a distillery for a similar capacity of 500 Hl/d of superfine ethanol using molasses, the filters juices and microalgae hydrolysate. For the second alternative, it intends a distillery where saving of 67 % for the molasses, and 22.73 % for the water, these results are experimentally obtained. The most feasible alternative obtain 5 years of payback period, 21 % of an IRR and U$D 37104 419.21 of NPV.
