The main objective of this research was to carry out a study of the production of bioethanol using ichu fibers (Festuca dolichophylla) as raw material, a plant that grows abundantly in the high Andean areas of Peru. The operating conditions presented in the proposed industrial scale process design were defined from an experimental methodology on a laboratory scale, in which an ethanol yield equal to 0.035 g ethanol/g ichu was obtained. This methodology consisted of four main stages, which were: alkaline pretreatment of the raw material, enzymatic hydrolysis, fermentation, and distillation for the separation of produced bioethanol. The parameters defined for each of the stages were validated, in order to ensure the repeatability of the process. On the other hand, the simulations of enzymatic hydrolysis and fermentation were carried out with MATLAB R2020a, and the simulation of continuous distillation using COCO simulator v3.4. Besides, the mass and energy balances of each equipment were carried out by numerical calculations with the help of the software COCO simulator v3.4, obtaining a weekly production of 44.36 liters of bioethanol with 70.4% of purity. Although the yield obtained (44.36 L ethanol / 1 ton of ichu), from a technical point of view, is 51.3% lower compared to bioethanol produced industrially from sugarcane juice (91 L ethanol / 1 ton of cane), this could be increased by also taking advantage of the hemicellulose, which constitutes 26.52% of ichu.
