The study aimed to determine the optimum proportion of corn cob biomass material and binder for the production of fuel briquettes. Three levels of binding agent (10%, 15%, and 20%) and three particle sizes (<2.2 mm, 2.2-3.2 mm, and >3.2 mm) were applied in the experiments. The physical and thermal properties of the fuel briquettes were characterized in terms of density, shatter resistance, breaking strength, and burning time. Results showed that a mixture of 20% binding agent and <2.2 mm particle size of corn cob biomass material exhibited the best formulation with a bulk density of 0.30 g cm-3, compression strength of 241.62 N, and shatter resistance of 99.25%. The potential energy density obtained for corn cob-based fuel briquettes was about 7890 MJ m-3. Ten pieces of the produced briquettes can boil 500 mL of water in nearly 6 minutes. The mean burning time was 34 minutes and 16 seconds. [ABSTRACT FROM AUTHOR]
