The research was developed in an agro-industrial SME in the canton of Junín, Manabí, Ecuador, under a descriptive, analytical and experimental approach aimed at the use of sugarcane bagasse (Saccharum officinarum) as solid biofuel, the generation of the waste was diagnosed by lifting the production process, direct weighing and material balance, and then the bagasse and the briquettes produced were characterized. Artisanal milling was identified as the critical stage of waste generation, with an overall factor of 0.4154 kg of wet bagasse per kg of processed cane, equivalent to 41.54%. Fresh bagasse presented high humidity (46.27-55.73 % bh), volatile matter of 84.16 ± 1.51 % bs and ashes of 3.90 ± 0.91 % bs, evidencing the need for prior conditioning for its energy use. Briquettes were made under a completely randomized design with four treatments defined by the internal matrix:peripheral layer ratio, using 20% cassava starch as a binder. The briquettes obtained registered humidity between 8.89 and 9.69%, volatile matter between 81.83 and 83.23 % bs, ash between 2.14 and 3.22 % and a higher calorific value between 17.91 and 18.40 MJ/kg bs. The statistical analysis showed significant differences between treatments (p < 0.05), and T1 presented the best overall performance by combining lower humidity, lower ash content and high energy quality. These results confirm that sugarcane bagasse constitutes a biomass/by-product with potential for valorization as a solid biofuel in agro-industrial SMEs.
