	abstract = {The fractionation of sugarcane bagasse (SB) by hydrothermal pretreatment (HP, autohydrolysis) followed by alkaline extraction (AE) and advanced oxidative pretreatment (AOP) for production of second-generation ethanol and biogas was investigated. The AOP of SB was optimized using a Doehlert design, varying the applied H2O2\&nbsp;load, liquid-to-solid ratio (LSR), and time. The responses evaluated were yield (Y), residual cellulose (RC), delignification (DE), and enzymatic conversion (EC). The AE of SB pretreated by HP led to 61.8\%\&nbsp;DE\&nbsp;(using 0.2 mol L-1\&nbsp;NaOH). This high lignin removal enabled substantial savings of H2O2\&nbsp;in the AOP. The optimized AOP conditions led to 78\%\&nbsp;Y, 82.2\%\&nbsp;RC, 42.7\%\&nbsp;DE, and 88.9\%\&nbsp;EC\&nbsp;(overall glucose yield of 60.9\%). Fermentation of the enzymatic hydrolysate with\&nbsp;Saccharomyces cerevisiae\&nbsp;yielded 190.8 Lethanol tonSB-1. Biogas production by anaerobic digestion of residual liquid streams of the pretreatment steps yielded 27.46 NLCH4 kgSB-1. An energy balance was estimated for the SB fractionation.},
