The use of lignocellulosic wastes for biorefinery adds value to biomass not used for cellulose pulp manufacturing. This papers presents the chemical and physic-chemical characteristics of eucalyptus biodeteriorated by xylophagous fungi. Samples of roots, stem, branches and leaves originated from the same tree and naturally attacked by white rot fungi, have been provided by a manufacturer. These samples have been processed into sawdust, and the fraction under 40 mesh has been submitted to analysis. The amount of ash, extractives, Klason lignin, soluble lignin, pentosans and holocellulose has been determined. Calorimetric and thermo gravimetric analysis have been carried out and spectrograms in the infrared have been taken. The samples of root, branch and steam have similar calorific value and thermo gravimetric behavior as the others. Root, branch and steam may be used for lignin extraction aiming at specific products synthesis.
