In search for renewable energy sources, the Brazilian residual biomasses stand out due to their favorable physical and chemical properties, low cost, and their being less pollutant. Therefore, they are likely to be used in biorefineries in the production of chemical inputs to substitute fossil fuels. This substitution is possible due to the high contents of carbohydrates (>40%), low contents of extractives (<20%), ashes (<8%) and moisture (<8%) found in these residual biomasses. High calorific values of all residues also offer them the chance to be used in combustion. A principal components analysis (PCA) was performed for better understanding of the samples and their hysic-chemical properties. Thus, this study aimed to characterize biomasses from the north (babassu residues, such as mesocarp and endocarp; pequi and Brazil nut) and northeast (agave and coconut) regions of Brazil, in order to contribute to the preservation of the environment and strengthen the economy of the region.Keywords: bioproducts; biorefinery; hysic-chemical properties; lignocellulosic residues.Practical Application: The Production of Sustainable Biofuels from the Residues and Wastes of Brazil principally of north of the country with technologies to help reduce the need for fossil diesel imports, improving the security of energy supply. Therefore rapid analytical methods can be used to analysis biomass and waste feedstocks pointing out the more promising candidates.
