Valorization of Waste Food Industry for Producing Second Generation Bioethanol

The aim of this report is to introduce a simulation model of the process of obtaining second-generation bioethanol from waste food industry (rice husk and whey), using Aspen HYSYS simulator in stationary state. The objective is to add value to this waste for the production of sustainable biofuels, helping to solve two problems shortages of oil and the generation of effluent dairies. The model includes the steps of hydrolysis, fermentation and separation of bioethanol generated from lignocellulosic waste (rice husk) in combination with whey, achieving the equipment design and operating conditions to reach a production of bioethanol of 7.57 t/h with a purity of 91.9% w/w from 28.89 t/h of pretreated biomass and 88 t/h whey.
