Quality of Life - 5.3.2 The Forestry-Wood Chain
Second Annual Progress Report - January 2002
- Abstract
Objectives
The overall aim of this project is to improve paper quality and production efficiency
thorough a more selective utilisation of European wood resources, focusing on Norway Spruce and
virgin pulp fibres for products based on mechanical pulp.
Results
Expected results:
- new knowledge on the variability of wood and fibre properties within and between forest
stands and trees in different regions of Europe
- new models for the prediction of these wood and fibre properties in trees and stands, adapted
to the growth conditions in different regions of Europe
- new knowledge on the cause and effect relationships between wood and fibre properties and
pulp properties, developed through laboratory refining of wood samples with well-defined
properties
- new industrial assortments of wood raw material, adapted to the production of newsprint
and LWC paper (lightweight coated) in different European regions. The criteria for the selection
of wood for the different assortments will be wood and fibre properties, processing potential,
availability in the feasible harvesting area and costs
- further development and validation of the selection criteria through pilot plant trials of 15-20
of the wood assortments above, showing especially high potentials in different regions
- verification of the general applicability of the results and the benefits for the participating mills
through full-scale mill trials of different industrial wood raw material assortments in different European
regions
- project workshops and reports for the participating companies, open papers and reports and an
open seminar at the end of the project.
Milestones
- Samples and forest data available
- List of "wood types" from different European regions with specific properties, based on wood
and fibre measurements and laboratory refining. Project workshop number 1
- Evaluated results from pilot plant trials. Project workshop number 2. Evaluation of the
potential application in the mills and by the process supplier, before starting the full-scale tests.
- Results from all research activities and application tests in mills available. Conference.
Benefits and Beneficiaries
Expected Benefits
- new data on the variability within and between European regions of wood and fibre properties
of importance for pulp and paper production, especially for the production of TMP (thermo mechanical
pulp) for newsprint and LWC paper (lightweight coated).
- new models for the prediction of these properties within and between trees and stands.
- new knowledge on the production of TMP from different wood raw material resources, based
on both refining of wood samples with well defined properties in the laboratory, pilot plant trials on
selected logs and full scale tests in mills.
- new industrial wood raw material assortments, with increased potentials for product quality
and new in I uniformity and overall production efficiency, considering fibre properties in trees,
processability, availability and costs in different regions of Europe.
- formation of a basis for future development of market driven allocation of forest resources
to the most suitable mill and product, in relation to the benefits and costs.
Beneficiaries
- The results are primarily useful for all European pulp and paper production, not only for
papers based on mechanical pulps.
- The results are also useful for the forestry sector and to some extent also for the sawmill
industry
- They may also be adapted to other softwood species than Norway Spruce.
- The data and models as well as the methodology developed will be a basis for further
research.
