The raw materials commonly used to produce pulp and paper in Brazil are woods from planted forests. Although with tremendous potential, the use of non-wood fibers is inexpressive. This study thus aimed to evaluate the use of sugarcane bagasse and bamboo to produce pulp and paper via physical, chemical and anatomical characterization, and to verify the influence of its properties on the process and the final product. Anatomical analysis of the fibers was performed (length and width from fibers and vessels, lumen width and cell wall thickness), as well as chemical component analysis (cellulose, hemicellulose, lignin, extractives and ash) and basic density of the materials. Moreover, felting rate, Runkel, Mulsteph and Boiler indexes, flexibility coefficient and wall fraction were generated. Results showed that both materials differed statistically in chemical properties, except for lignin content; density and anatomical properties, excluding vessel width and felting rate. Bamboo presented higher values ​​cellulose (52.96%), minerals (2.34%), density (0.461 g/cm³), wall fraction (67.84%) and Runkel (2.11), Mulsteph (0.90) and Boiler indices (0.81) values, whereas sugarcane bagasse presented higher hemicellulose (17.63%), extractives (12.81%) and flexibility coefficient (46.19%) values. Most properties were similar to those observed in raw materials commonly used for this purpose. Therefore, these two materials have potential for use in the pulp and paper industries.
