ABSTRACT: Lignocellulosic residues resulting
from agricultural activities and urban centers cause pollution. A possible
solution to this problem is to combine these residues with woody plants to
produce particleboards. The purpose of this study was to evaluate decay
resistance, coating and burning properties and the change of color caused by
accelerated weathering of particleboards manufactured with a combination of 3
woody species used for commercial reforestation in tropical areas (Cupressus lusitanica, Gmelina arborea and Tectona grandis), pineapple (Ananas
comosus) leaves from the crown and the plant (PL), empty fruit bunch of Elaeis guineensis (EBF) and tetra pak
packages (TP). According to the results, the mixtures of T. grandis and EFB were classified as moderately resistant and
other mixtures (woody species and PL or TP) were classified as slightly
resistant. The finish performance test determined that the mixtures with TP
presented the best performance, followed by the mixtures with oil palm
components and the mixtures composed of pineapple leaves. Regarding lacquer consumption, no
differences were found between the mixtures. The combustion test determined
that particleboards with TP and EFB showed the highest resistance to
combustion, while pineapple presented the lowest resistances to combustion. In
the accelerated weathering exposure test, the mixtures of the three species with
TP showed the best performance in accelerated weathering. Contrariwise, the
mixtures with pineapple leaves showed the lowest resistance to accelerated
weathering. Oil palm particleboards presented lower resistance to weathering
than TP, though higher than pineapple leaves’ resistance.
