Abstract

The bioethanol that is produced worldwide is mostly obtained from agricultural crops such as sugarcane and corn. However, it has negative environmental effects, so the option of producing bioethanol from agricultural waste arises. This work evaluates the feasibility to produce second generation bietanol from oranges residues (peel and bagasse) produced in the province of Chapare, Bolivia. The estimation is carried out from the reducing sugars, determined by the DNS method, individual sugars, determined by HPLC, produced by acidic and enzymatic hydrolysis of the residues. Similarly, the amount of ethanol produced by fermentation of the samples is quantified. Regarding the results obtained, the best alternative in terms of bioethanol production is the enzymatic hydrolysis. An economic and environmental impact evaluation are also included considering the production of bioethanol from real orange residues.
