​Massive expansion works are being carried out at Södra Cell Värö pulp mill in Varberg, Sweden. Once completed, the mill will rank among the world's largest softwood sulphate pulp makers.

The expansion involves increasing current annual production capacity of 425,000 tonnes to 700,000 tonnes.

Valmet, a leading global developer and supplier of services and technologies for the pulp, paper and energy industries was commissioned by Södra Cell Värö to deliver the entire project and chose COWI to provide project planning for large parts of the expansion.

Replacing fossil fuel in society

The production of pulp generates a lot of energy, and the mill supplies some of it to the municipality as an alternative to fossil fuels.

The expansion will enable Södra Cell Värö to increase its supply of this green energy.

New technologies

Södra Cell Värö itself is already independent of fossil fuels for normal operation. Apart from increase higher pulp production, the expansion will also make the mill even more energy-efficient.

"With the expansion, new technologies and equipment are introduced, making the production more environmentally friendly and less energy-consuming," says Uno Olsson, Forest Industry Marketing Manager at COWI.

Expansion while operating

The mill will be in operation during most of the expansion:

"Our work is greatly complicated by the fact that the mill will be in full operation while we work. For instance while we modify and replace different equipment. The mill will only close for very few days, making this much more challenging than a greenfield project," says Olsson.

COWI's services

COWI’s provides electrical and instrument planning of the cooking and white liquor-plant as well as plant design of the fibre line.

The assignment is expected to run until September 2015 and the expanded mill is planned to come online during the third quarter of 2016.
