Rendimento em madeira serrada e quantificação de resíduos de três espécies tropicais - itaúba (Mezilaurus itauba), angelim pedra (Hymenolobium petraeum Duck) e cupiúba (Goupia glara)

Abstract

The objective of this work was to collect data and technical information regarding the yield of sawn wood and quantification of residues of the tropical species Itaúba (Mezilaurus itauba), Angelim Pedra (Hymenolobium petraeum Ducke) and Cupiúba (Goupia glabra). Twenty logs were selected, with 8 from Itaúba, 5 from Angelim Pedra and 7 from Cupiúba. It was verified that among the 3 species studied the Angelim stone was the species that presented the highest yield 58.5%, and the species that presented the lowest yield was Cupiúba 41.6%, because it had the presence of logs and was the one that presented the largest residue generation during the unfolding operation. The study shows that there is no significant difference with income for Angelim Pedra and Itaúba, differing only in Cupiúba.
