This study aimed at investigating the binderless densification of biomass for the production of a durable solid biofuel by mixing cassava rhizome, sugarcane bagasse, and sugarcane straw. Six different treatments were applied with specific percentages of these three biomass feedstocks for the densification in a lab-scale press with heating of 120 °C. Three blend treatments and three 100% material treatments (without mix) were analyzed. Achieved briquettes were examined via various tests including proximate analysis, volumetric expansion, compression test, and energy index to assess the mechanical and energetic properties. Results indicated that the mixtures are suitable for the production of briquettes and treatment B2 was the best blend for briquette production. This study suggested that binderless densification of biomass can be achieved with the mixing of cassava rhizome, sugarcane bagasse, and sugarcane straw, which will support the development of qualified solid biofuels without the cost of binders.

本研究旨在通过混合木薯根茎、甘蔗渣和甘蔗秸秆来研究生物质的无粘合剂致密化，以生产耐用的固体生物燃料。使用这三种生物质原料的特定百分比应用六种不同的处理方法，以在加热为 120 °C 的实验室规模压机中进行致密化。分析了三种混合处理和三种 100% 材料处理（无混合）。获得的煤球通过各种测试进行检查，包括近似分析、体积膨胀、压缩测试和能量指数，以评估机械和能量特性。结果表明，该混合物适合生产型煤，处理 B2 是生产型煤的最佳混合物。
