The mahogany fruit shells underwent a torrefaction process to produce charcoal briquettes using Cornick industry wastewater as binder and a charcoal briquette machine. The density and shattering index of the four treatments, with charcoal-to binder ratios of 65:35 (T1), 60:40 (T2), 55:45 (T3), and 50:50 (T4), ranged from 0.5146 g/cm3 to 0.5608 g/cm3 and from 0.6333 to 0.9827, respectively. Subsequently, energy efficiency testing was conducted on the mahogany fruit shell briquettes. The water boiling time varied from 16.57 minutes to 32.42 minutes, while the water evaporating time ranged from 29.48 minutes to 40.55 minutes. Moreover, the mass of briquettes used varied from 55 grams to 74.67 grams, and the maximum temperature of the stove ranged from 138.67 to 171 degrees. The treatment that exhibits the most favorable performance is 50:50 (T4), as it demonstrates an exceptional capacity to expedite the boiling and evaporation of water when compared to other treatments. Furthermore, its shattering index is high among the other treatments. This study compares Treatment 50-50 with the standard briquette to determine any significant differences in their physical characteristics and energy efficiency parameters. The standard briquette differs significantly from Treatment 50-50 in terms of density and shattering index. The standard briquette is denser than Treatment 50-50, and Treatment 50-50 performs better in shattering index. When it comes to energy efficiency, the only significant difference is in water boiling time, with Treatment 50-50 boiling water faster than the standard briquette. Therefore, Treatment 50-50 can be considered as an alternative to the standard briquette.
