The objective of the present was to characterize the quality of briquettes produced with fines of vegetable coal and bamboo residues, under different formulations. Specific gravity density, bulk density mass, moisture content and speed or rate of thermic degradation were evaluated. Compressive strength and rotation test were applied to the briquettes. Superior and inferior calorific values from briquettes were estimate by adjusted equations. Briquettes produced with the highest percentages of vegetable coal fines presented higher specific gravity, bulk density, ash content and fixed carbon. It also presented resistance to fall and abrasion. Briquettes with higher bamboo residues content presented faster degradation, higher compressive strength, beyond higher volatile matters and calorific value.
