Kraft Pulping Properties of Acacia mearnsii and Eucalyptus grandis Grown in Zimbabwe
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: A. Muneri --- , AustraliaPulpwood samples from 8-year old Acacia mearnsii and Eucalyptus grandis plantations grown in Zimbabwe were evaluated for kraft pulping, bleaching and papermaking properties. The possibility of co-pulping the two species was also investigated. -
A Comparison of the kraft pulp properties of P. elliottii and the P. elliottii x P. caribaea var. hondurensis hybrid grown in Queensland, Australia
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: T.K. Stanger --- Shaw Research Centre, South Africa M. J.P. Shaw --- Shaw Research Centre, South Africa R. Braunstein --- , South Africa D.G. Nikles --- , AustraliaThe interspecific hybrid between P. elliottii var. elliottii and P. caribaea var. hondurensis has recently been accepted for planting operationally as an alternative to P. elliottii by Sappi in South Africa. Some concerns have been expressed as to the suitability... -
Study on the Prepressing of Flakeboard Containing Waste Paper
Item type: Journal Article • Journal: South African Forestry Journal • Authors: Günther Gerischer --- Faculty of Forestry, Rep. of South Africa Dave Reeves --- Faculty of Forestry, Rep. of South AfricaThe purpose of this study was to determine whether the strength properties of a composite board containing waste paper as a core material, could be improved by the prior prepressing of the core material before pressing the product to final... -
Measurement of cellulose content, Kraft pulp yield and basic density in eucalypt woodmeal using multisite and multispecies near infra-red spectroscopic calibrations
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: GM Downes --- , Australia R Meder --- , Australia H Bond --- , Australia N Ebdon --- , Australia C Hicks --- , Australia C Harwood --- , AustraliaPrevious descriptions of multisite and multispecies near infra-red (NIR) spectroscopic calibrations for predicting cellulose content (CC) and Kraft pulp yield (KPY) in eucalypt woodmeal demonstrated that large, single calibrations provide precise predictions for a wide range of sites and species... -
Developing and evaluating a multisite and multispecies NIR calibration for the prediction of Kraft pulp yield in eucalypts
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: GM Downes R Meder C Hicks N EbdonOver recent years the application of near infra-red (NIR) spectroscopy to the prediction of wood properties has been demonstrated in many proof-of-concept studies. Previous work has demonstrated that NIR measurements can be used to predict basic density from woodmeal, chainsaw... -
The impact of mechanical log surface damage on chip size uniformity during debranching and debarking Eucalyptus pulpwood logs using a single-grip harvester
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Jaco-Pierre van der Merwe --- Department of Forest and Wood Science, South Africa Pierre Ackerman --- Department of Forest and Wood Science, South Africa Reino Pulkki --- Department of Forest and Wood Science, South Africa Dirk Längin --- , South AfricaMechanised harvesting operations are becoming more prevalent in South Africa with the realisation that motormanual and manual harvesting operations pose significant health and safety risks to workers. The damage inflicted by single-grip harvester feed rollers and delimbing knives on log... -
The impact of log surface damage caused by harvester Eucalyptus debarking on pulp value recovery
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Jaco-Pierre van der Merwe --- Department of Forest and Wood Science, South Africa Reino Pulkki --- Department of Forest and Wood Science, South Africa Pierre Ackerman --- Department of Forest and Wood Science, South Africa Dirk Längin --- Mondi Ltd, South AfricaMechanised harvesting operations are growing in popularity in South Africa, as motor-manual and manual harvesting operations pose significant health and safety risks to workers. Potential damage inflicted by single-grip harvester feed rollers and delimbing knives on the log surface during... -
Sawn-timber and kraft pulp properties of Pinus elliottii × Pinus caribaea var. hondurensis and Pinus patula × Pinus tecunumanii hybrids and their parental species
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: André Nel --- Shaw Research Centre, Sappi Forests Research, South Africa Francois S Malan --- Retired, South Africa Ron Braunstein --- Sappi Technology Centre, South Africa C Brand Wessels --- Department of Forest and Wood Science, South Africa Arnulf Kanzler --- Shaw Research Centre, Sappi Forests Research, South AfricaA study was undertaken to evaluate the quality of the timber produced by Pinus elliottii × Pinus caribaea var. hondurensis (PECH) and the Pinus patula × Pinus tecunumanii low elevation (PPTL) and high elevation (PPTH) hybrids and their parent species... -
Characterisation of eucalypt wood from trees with dieback for production of Kraft pulp
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Ana Paula Câmara --- , Brazil Graziela Baptista Vidaurre --- , Brazil Suellen Rios Martins --- , Brazil João Gabriel Missia da Silva --- , Brazil Humberto Fantuzzi Neto --- , Brazil Jean Carlos Lopes de Oliveira --- , Brazil Amélia Guimarães Carvalho --- , Brazil José Cola Zanuncio --- , Brazil Leandro de Siqueira --- , BrazilDieback, resulting from abiotic stress, compromises the development of trees and the quality of wood. The objective of this work was to characterise the wood and cellulosic pulp produced from young eucalypt wood with dieback. Eucalyptus grandis × Eucalyptus urophylla...
