| description | Brazil is the world's largest producer of sugarcane, from which sugar and ethanol are obtained. However, after the production process, waste remains, among which stands out the bagasse, which generates millions of tons annually. The bagasse can be used for many purposes; however, it is important to know its properties in order to make the best use of it. Thus, the present study aimed to evaluate the bagasse's physical, chemical, and anatomical properties, as well as its potential for energy generation and pulp production. The evaluations of the characteristics and potential of bagasse followed the recommendations and standards of the Brazilian Association of Technical Standards [ABNT], the Technical Association of the Pulp & Paper Industry Inc. [TAPPI], and the International Association of Wood Anatomists [IAWA]. Based on the results, a low density (0.048 g/cm3) was observed; high ash (5.8%) and extractives (5.7%) content, and low lignin content (24.5%); and fibers with moderately long length (1.60 mm), the other dimensions being compatible with eucalyptus wood; and regular anatomical quality indicators for paper production. The bagasse has a good energetic potential in nature, and the heat treatment provides a significant gain in this regard. In addition, the bagasse also has good potential for pulp production, with yields similar to those reported for eucalyptus wood, but with a higher reject content, and less viscosity and hexenuronic acids content. In general, sugarcane bagasse has interesting properties and can be better used, either for energy generation or pulp production. |

O Brasil é o maior produtor mundial de cana, a partir da qual se obtém o açúcar e o etanol. Porém após o processo produtivo sobram resíduos, entre os quais se destaca o bagaço, que gera milhões de toneladas anualmente. O bagaço pode ser utilizado para várias finalidades, no entanto é importante conhecer suas propriedades e aptidões para realizar o melhor aproveitamento possível. Desta forma, o presente estudo teve como objetivo avaliar as propriedades físicas, químicas e anatômicas do bagaço, bem como seu potencial para geração de energia e produção de polpa celulósica. As avaliações das características e potencialidades do bagaço seguiram as recomendações e normas da Associação Brasileira de Normas Técnicas [ABNT], Technical Association of Pulp and Paper Industry [TAPPI] e International Association of Wood Anatomists [IAWA]. Com base nos resultados observou-se baixa densidade aparente (0,048 g/cm3); alto teor de cinzas (5,8%) e extrativos (5,7%), e baixo teor de lignina (24,5%); fibras com comprimento moderadamente longo (1,60 mm), sendo as demais dimensões compatíveis com a madeira de eucalipto; e indicadores anatômicos de qualidade regulares para produção de papel. O bagaço apresenta bom potencial energético in natura, e o tratamento térmico proporciona um ganho significativo neste quesito. Além disso, o bagaço também apresenta bom potencial para produção de polpa celulósica, com rendimentos similares aos relatados para a madeira de eucalipto, porém com maior teor de rejeitos, e menor viscosidade e teor de ácidos hexenurônicos. De forma geral, o bagaço de cana-de-açúcar tem propriedades interessantes e pode ser melhor aproveitado, seja para geração de energia ou produção de polpa celulósica.
