The pulping and papermaking potential of plantation-grown Eucalyptus deglupta from Papua New Guinea. Part 1. Pulpwood characteristics.
The need to consider raw materials for future pulping industries in tropical areas led to an investigation of the suitability of Eucalyptus deglupta as pulpwood. This study examined samples from plantation-grown material of 3 to 20 years of age collected from Keravat, East New Britain Province, Papua New Guinea. This paper reports on the variability of wood properties within tree, between tree and with age. Weighted mean values were calculated for both basic density and fibre length of individual sample trees and for each age class sampled. Other wood properties including anatomical properties having a possible impact on pulp quality were examined. The basic density showed an increasing trend with age. Fibre length increased from pith to cambium and also with increasing age.
