http://dx.doi.org/10.5902/198050988454The present study evaluated the energy reuse potential of the wooden residues and its derivatives generated in the industrial furniture stave of Ubá, Minas Gerais state, Brazil. Reconstituted panels of MDF (medium density fiberboard), particleboards and plywood were characterized and classified. A research carried out in 11 furniture plants verified that the wooden residues represent more than 90% of the solid wastes. Besides of this the large amount generated, no integrated action was identified to the management of the residues, neglecting its environmental and sanitary risks, as well as its energy use potential. However, the moisture and calorific power of the residues demonstrated a high potential energy use through the briquette production. The gases generated by combustion of the residues did not presented toxic substances above the limits of Brazilian legislation. However, the leached ashes of the residues of agglomerated BP (low pressure) and FF (finish foil) presented high chromium concentrations, classifying them as Class I (dangerous), according to ABNT/NBR 10004/2004.
