The first market targeted was lignin as a replacement for PF resins in wood products. Future markets include rigid PU foams and thermoplastics.

Looking at other products-for
example, polyurethane foam-lignin
can replace up to 25 percent of polyol.
With depolymerized lignin, the substitution rate can be much higher. Hence,
a main focus of FPInnovations' work is
the development of cost-effective lignin
depolymerization approaches.
Other added-value possibilities include
lignin-based polymers being used as dispersants (textile, wallboard and concrete
applications) or as flocculants, for example,
in sludge dewatering and suspended solids
removal from effluent streams to replace
petroleum-based flocculants. "In the next
few years, we will try to bring these innovations to an industrial level," says Paleologou.
"We are working to create a lignin culture."
When asked to compare LignoForce with
other technologies, Paleologou says other new
processes give good quality lignin in the acid
form. "With respect to the equipment needed,
we feel that we have an advantage on system
footprint. On the operating cost side, we significantly lower carbon dioxide consumption.
Another important advantage of our system is
the elimination of sulphur compound emissions from both process and product."
Huge strides have been made recently in
what was originally called the forest biorefinery. Maybe it is time to move on from that generalized term as specific products have been
successfully brought to market. As Paleologou
points out, the developments in nano-technology and lignin are inter-related. "We developed a lot of building blocks at FPInnovations
over the last 10 years. We took the tree apart
and now we are trying to put it back together
in the optimum forms-for example, using
cellulose nanocrystals in lignin-based phenolic resins.
"Conventional fibers, cellulose nanocrystals,
cellulose filaments, lignin-they are all now
available commercially. How can we put them
together again in different forms and shapes to
address different market needs?"
