The aim of this work was to evaluate the feasibility of a small-scale biorefinery based on sugar cane bagasse for the production of three different chemical products (furfural, xylitol and xylose syrup) from the pretreatment liquor, and the production of MDF fiber boards or electricity generation from the solid residual fraction. A model for a small-sized biorefinery was developed, determining the better scenario based on market prices of the products, production costs and estimation of the payback period for the selected scenario.
