“…Branches and sticks of Ilex paraguariensis show similar density, average of 0.406 g cm − 3 . Bamboo density average observed in this study corroborate those found by Vale et al [25] who analyzed B. vulgaris in different positions (bottom, middle and top) with one and three years of age. The authors obtained mean values varying between 0.505 and 0.609 g cm − 3 over height, individuals were studied at three years of age, while Brito et al [26] reported density 0.687 g cm − 3 .…”

“…Average values of the different bamboo species did not differ statistically from those found in mate sticks. Bamboo species showed higher volatile content, when compared to the values observed by Rambo et al [11], Vale et al [25] and Rousset et al [32], the authors found values of 81.08, 78.14 and 80.13%, respectively. Sette Junior et al [35] found 82.2% volatile content for the sample of Eucalyptus grandis x Eucalyptus urophylla hybrid.…”

“…In general, the higher the fix carbon content, the better the quality of material for burning, as this fuel will burn more slowly and with less flame formation [18,26]. Rambo et al [11], Vale et al [25] and Rousset et al [32] found a fix carbon content of 17.20, 17.66 and 17.75%, respectively, in different bamboo species.…”

Fossil fuels are being replaced by clean energy sources. Lignocellulosic biomass is considered an eco-friendly alternative, as it is a renewable raw material with high energy potential. In this context, the aim of this study was to determine the biomass energy properties of three bamboo species and mate. Thus, three species of bamboo (Bambusa vulgaris Var. Vittata, Dendrocalamus asper and Phyllostachys aurea) and Ilex paraguariensis co-products (branches and sticks) were performed. The particle size, basic density, moisture content volatiles content, ashes content, fix carbon, gross and net calorific value and energy density of these biomasses were evaluated. The biomasses analyzed here were considered suitable for energy purposes, in general, these presented volatile content between 75 and 85 %, fixed carbon content between 15 and 25% and ash content close to 1%. Average fix carbon content of all analyzed biomass was 16.13%. Ash content of Phyllostachys aurea, branches of Ilex paraguariensis and Dendrocalamus asper presented lower values, average of 1.63%. Bambusa vulgaris and Ilex paraguariensis sticks presented higher values, average of 2.65%. Phyllostachys aurea presented gross calorific value higher than, average of 19.35 MJ kg− 1. Bambusa vulgaris, Dendrocalamus asper, Ilex paraguariensis branches and sticks presented statistically equal values. Bambusa vulgaris, Dendrocalamus asper, Phyllostachys aurea showed net calorific value higher to the other analyzed materials and did not present statistical difference. Basic energy density of Phyllostachys aurea was higher to bamboo species. Ilex paraguariensis showed the lowest values with no statistical difference for branches and sticks. Article highlights Knowledge of biomass properties enables the use of residues in bioenergy production as an eco-friendly alternative. Bamboo and Mate co-products have desirable characteristics and potential to produce bioenergy. The energetic performance of bamboo biomass was superior when compared to the branches and sticks of Ilex paraguariensis.

“…A densidade básica média para o bagaço e bambu foi de 0,146 ± 0,024 g/cm³ e 0,461 ± 0,070 g/cm³, respectivamente. Esses resultados estão em concordância com trabalhos realizados por Tomazello Filho & Azinni (1987), Silva & Morais (2008), Santi (2015) e Vale et al (2017), que encontraram densidades variando entre 0,090 e 0,160 g/cm³ para o bagaço, e 0,450 e 0,710 g/cm³ para o bambu. A densidade do bambu é aproximadamente 3,2 vezes maior que a densidade do bagaço.…”

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.

“…The recognition of the great industrial potential of bamboos was not sufficient to create a considerable use of these species in Brazil, especially due to the lack of technical knowledge about them. In order to change this situation and stimulate the study, the cultivation and the use of bamboos in Brazil, the National Policy for the Incentive of Bamboo M anagement and Cultivation was established in 2011 (Do Vale et al 2017;Sette Junior, 2017;Brant et al 2019), instituted by Law number 12,484 /2011 (Brasil 2011).…”

Despite of the wide use worldwide, the industrial potential of bamboo species in Brazil is not much investigated. However, some encouragement to revert this situation was created in last few years. The aim of this research was to evaluate the technological characteristics of the Bambusa vulgaris biomass for the production of pulp by the kraft process. The technological characteristics of the raw material were determined by the basic density, the chemical composition and the morphology of the fibers. The cooking process was carried out with the application of eight charges of active alkali, in 90 minutes of heating time and 60 minutes in the maximum temperature of 170ºC. All analyzes were also executed with the Eucalyptus spp. and the Pinus spp., in order to make a complete comparison among the species Bambusa vulgaris and the two most used raw materials for the pulp production in Brazil. The Bambusa vulgaris presented a higher basic density, lower holocellulose content and a higher total extractive content. Its fibers have intermediate length and wall thickness, similar to the Eucalyptus spp. and the Pinus spp. Considering the kraft pulping process, the species Bambusa vulgaris demonstrated to be easier to delignify besides presenting almost zero reject content and smaller consumption of active alkali. However, the Eucalyptus spp. and the Pinus spp. obtained the best yields, the lowest specific consumption of raw material and better selectivities.
