Rottneros AB, Väsby, Sweden, will invest 45 million kroner (approximately $6.157 million) to upgrade the soda recovery boiler at its Vallvik market pulp mill in Sweden. The upgrade follows a SEK 77 million project in December to improve evaporator operations. Both projects are part of an effort to boost overall production capacity. The boiler upgrade will take place in the fourth quarter during the mill's annual maintenance shutdown.

The company notes that increased evaporator capacity means that more of the mill's internal process water can be evaporated, which in turn makes it possible to recover and incinerate more organic material. "Put simply, this improvement to the soda recovery boiler increases the capacity for incineration, which increases Vallvik's output of bioenergy," explains Ole Terland, president and CEO.

The Vallvik Mill produces two grades of long-fiber sulfate pulp: fully bleached, ECF, and unbleached sulfate pulp and unbleached kraft pulp. It is permitted to produce 220,000 metric tpy. In 2008 the mill celebrated its centennial as a pulp producer. It employs 180 people.
