Resumo: The aim of this study was to characterise the lignocellulosic fractions of pruning waste from tree species showingpotential for furniture production in Acaraú, Ceará. The experiment was conducted in a completely randomised, split-plot design, withthe plots corresponding to two water regimes (irrigated for one year and irrigated for three years) and the sub-plots to eighttree species, with three replications. The chemical attributes were determined after seven years. Except for the insoluble lignincontent, there was a significant effect from the different species in terms of the chemical properties of the wood. The resultsfor the lignocellulosic fractions show the possibility of developing technological ways of adding value to these waste products,especially considering their lignin content. The different species also showed potential for use in producing cellulose pulp, withthe exception ofHandroant hus impetiginosus due to its high ash content. The results of this study offer new perspectives forfuture research into the use of forestry waste.
