Valmet: Valmet-supplied LignoBoost plant now handed over to Stora Enso's Sunila mill in Finland

Valmet Corporation's press release on October 6, 2015 at 11:00 a.m. EET

Stora Enso's Sunila mill is now running the Valmet-supplied LignoBoost lignin
separation plant. As the last part of the handover process, the lignin dryer,
was taken over by the Stora Enso team on September 15, 2015. The LignoBoost
plant is integrated with the pulp mill to separate and collect lignin from
the black liquor. This is a significant step in transforming the Sunila mill
towards an innovative and customer focused biorefinery. The plant has been
running since January 2015 and production has been ramped up during the year.

"Through the lignin extraction process we have replaced a great amount of
natural gas with the dried lignin produced in the new LignoBoost plant, and
by doing that reduced our carbon dioxide emissions. We are developing this
new product and working together with our customers to start external sales,"
saysSakari Eloranta
, Senior Vice President, Operations and Investment Projects, Stora Enso

"This is the second commercial scale LignoBoost plant in the world. We
continue to develop this technology, as we see a great potential in utilizing
lignin in various uses. Lignin powder can be used as raw material at the mill
for firing or it can be converted into other materials and products. Lignin
separation will at the same time improve the environmental performance of the
mill," saysAnders Larsson
, Director, Bio materials, Pulp and Energy business line, Valmet

LignoBoost lignin separation technology

LignoBoost is one of Valmet's biotechnology solutions that responds to the
growing interest for utilizing bio-based raw materials. LignoBoost is
Valmet's patented method of extracting lignin from Kraft Pulp process' spent
cocking chemicals, the black liquor. By treating the black liquor with
carbon-dioxide and a strong acid the lignin is precipitated, which is then
washed and dried. Lignin is an organic polymer and has a heating value
similar to carbon. Lignin is besides cellulose and hemi cellulose the most
common material in wood.

In addition to LignoBoost, Valmet has several bio initiatives including
products such as bio coal, solutions for second generation ethanol, pyrolysis
oil as well as direct and indirect gasification of biomaterials.
