 Metso Corporation : Metso-supplied world's first commercial LignoBoost plant
                 successfully starts up at Domtar in the USA

Metso Corporation's press release on April 30, 2013 at 11:00 a.m. local time

Domtar has successfully started up a commercial-scale LignoBoost(TM) lignin
separation plant at its Plymouth, North Carolina mill, in the USA. This is the
first commercial installation of a LignoBoost plant in the world and the
technology is supplied by Metso.

The LignoBoost plant is integrated with the pulp mill and separates and
collects lignin from the pulping liquor. This provides the Plymouth NC mill
with numerous benefits. Lignin is a high-quality bio-based alternative to
fossil fuel based materials. Separation of a portion of the mill's total
lignin production also off-loads the recovery boiler, and allows an increase
in pulp production capacity.

Domtar's production of BioChoice(TM) lignin began in February with a targeted
rate of 75 tons a day. A wide range of applications and markets for BioChoice
lignin are being developed including fuels, resins, and thermoplastics. Having
lignin available in large quantities and high quality from the Domtar plant
will help develop the future lignin market for the industry.

"The technology has been developed by Innventia in Sweden, in association
with Chalmers University of Technology. Metso purchased it and is furthering
the development. We continue to work together to refine the technology to
develop new lignin applications in partnership for current and future
customers. LignoBoost has generated a great deal of interest in the pulp &
paper industry globally and this is a major breakthrough for all parties
involved in this first-of-a-kind project," says Gene Christiansen, Senior
Manager, Business Development Innovations at Metso's Power business line for
North America.
