Pellets for energy purposes are produced from various sources, such as residues from sawmills, carpentry, and other waste materials. As industry demands are always increasing, it is necessary to find new sources of biomass suitable for pelletization according to international standards, so that the present research aimed to characterize pellets from 17 sources of woody and agricultural biomass. Physical, mechanical, and energetic characterization was realized, evaluating length, diameter, density, moisture content, ashes, fixed carbon, gross calorific value, durability, and compressive resistance for pellet biofuels from agricultural and forestry sources. Pellets from all sources had moisture content less than 10%. The ash content in forestry residues was lower than 1% (except for laeta oak sawdust), in agricultural residues the values range from 2.12 to 10.54% (except for oil palm fiber). The gross calorific values were higher than 16.5 MJ kg⁻¹. The durability showed the range 73.61–99.15%, and compressive resistance, the range 322–1,729 N mm⁻¹, with oil palm fiber residues registering the lowest value, and laeta oak sawdust the highest. According to these results, pellets from forestry and agricultural sources had good characteristics for industrial and residential uses.

用于能源目的的颗粒由各种来源生产，例如来自锯木厂、木工和其他废料的残留物。由于行业需求不断增加，有必要根据国际标准寻找适合造粒的新生物质来源，因此本研究旨在表征来自 17 种木质和农业生物质来源的颗粒。实现了物理、机械和能量表征，评估了农业和林业来源的颗粒生物燃料的长度、直径、密度、水分含量、灰分、固定碳、总热值、耐久性和抗压性。所有来源的颗粒的水分含量都低于 10%。林业残留物中灰分含量低于1%（橡木锯末除外），在农业残留物中，该值范围为 2.12 至 10.54%（油棕纤维除外）。总热值高于 16.5 MJ kg^-1。耐用性范围为 73.61-99.15%，抗压性范围为 322-1,729 N mm ^-1，油棕纤维残留物的值最低，而橡木锯末的值最高。根据这些结果，来自林业和农业的颗粒具有良好的工业和住宅用途特性。
