This research aimed to analyze the quality of briquettes made from mixtures of bamboo waste, cellulosic pulp residues and charcoal fines wastes under different formulations. Determined were: the moisture content, bulk density and the calorific value of briquettes. Briquettes were subjected to compressive strength tests and rotation and chemical analysis. The results were interpreted by univariate and multivariate analysis. Briquettes produced only with charcoal wastes fines showed higher values of bulk density and compressive strength and lower friability. Briquettes produced with bamboo waste and coal chaff showed higher moisture content, volatile materials content and calorific value. Briquettes produced from cellulose residues showed higher levels of fixed carbon and ash content. In general, briquettes produced from lingo-cellulosic waste presented characteristics for bioenergetics use, however qualitative and quantitative studies of combustion gases are recommended, when the objective is use for food cooking.
