The production of ethanol from cashew apple bagasse is attractive in terms of the energy balance and reducing emissions and may therefore be used as a Supplementary material for ethanol production in Brazil. Xylitol, a high-value polyalcohol, may be produced by the reduction of d-xylose derived from hemicellulose fraction of lignocellulose, which has applications in the medical, odontological, food and cosmetic industries [5] and [6]. It has a similar sweetness to sucrose [7] and can be employed in specific diets for people with special caloric needs, such as diabetics [8].
