Start-up for Iggesund Paperboard new recovery boiler

Iggesund Paperboard’s new recovery boiler and turbine is set to start at
Iggesund Mill. At almost 240 million Euro, this is the mill’s largest investment
ever.

“It feels terrific that the project has come to a successful conclusion, and
that we’ve done so within the projected time frames,” comments Björn Kvick, head
of Iggesund Paperboard.

The recovery boiler is the “heart” of a sulphate pulp mill and serves this
function at Iggesund Mill, which produces the world’s leading quality
paperboard, Invercote. The boiler is built to withstand higher pressure than any
other recovery boiler in Europe. This increased pressure makes it possible to
generate more electricity. The new turbine should be able to supply 520 GWh/year
and in the longer term also make Iggesund Mill completely self-sufficient in
electricity.

Concurrently with the inve stment in its recovery boiler in Sweden, Iggesund
Paperboard is also investing 123 million Euro in a biofuel boiler at the mill in
Workington, England. Both investments will help reduce fossil carbon emissions
from the mills.
