Industry Innovations
 Historical –
Adapted processing technologies to fit
natural raw materials
 Current –
Wood supply altered to better fit current
processing technologies
 Future
Wood supply and processing
technologies altered in concert
4
Co evolution of Raw Materials &
Processing Methods: Low Lignin Trees
 Positive Impacts -Reduced cost of pulp production and
improved pulp quality
 Negative Impacts –
Reduced ability of mill to supply its
own energy needs
5
Low Lignin Trees & Energy Generation
Technologies on -- Kraft Linerboard Costs
CURRENT
 Recovery Boiler
Linerboard cost
optimum closer to
20% than 15%
Weighted pulp yield
for 20% lignin 68%
FUTURE
 Black Liquor Gasification
Linerboard cost optimum
closer to 12-15%
Weighted pulp yield for
15% lignin 75%

Clonal Selection
 Preferred Outcrossing
Distribution of Individuals
 Oldest pedigrees three
generations
 Quantitative traits
 Combinations of
multiple genes/alleles
# Genotypes
 No inbreds
 Asexual capture &

Key Barriers to –
Improved Germplasm
 Cost effective clonal
seedling production
 Rapid cycle breeding
 Controlled flowering
 Early estimation of
phenotypes
 Societal acceptance of
genetically engineered
trees
 Sterility
 Gene discovery
 Molecular markers
 Models for fiber properties
 Low cost, rapid,

nondestructive methods for
wood and fiber property
estimation
 Knowledge of genes that
when modified improve
processing synergies and
value of end products
Knowledge of synergies
between wood, fiber, paper
and processing
technologies
12
Alternative Co evolutionary
Ideas for -- New Tree Materials
 New wall layer arrangements to affect need
for refining and influence fiber-fiber bonding
Thin S1 layer
Altered arrangement of S1 layer
 Super efficient wood and fungal pairs for
ultra-rapid biopulping
 Novel biosynthesis of alternative polymers
in secondary wall that promote bonding
