The recovery boiler flue has always dominated the skyline in the classic pulp mill picture. But at Sodra, another majestic feature is competing for attention within the pulp mill's landscape -- the wind turbine. Energy has always been an issue for the pulp and paper industry but uncertainty about energy supply and cost has deepened, and environmental concerns have intensified to the point where energy has become the issue. Sodra has arguably taken rather more drastic action than its peers in tackling the energy problem by transforming itself from an energy consumer to an important energy producer. The year 2008 will be the first year in which Sodra Cell's combined pulp operations produce more electricity than they consume, with sales back to the grid of 100 GWh. There are three potential revenue sources from Sodra Cell's energy generation strategy: generating surplus electricity for sale to the national grid; refining renewable energy forms such as lignin; and seffing process heat for local heating systems.
