“With a strong environmental
profile and a low carbon footprint, we can help our customers reach their environmental goals. Our environmental data will be the new industry benchmark, we will increase tensile strength by more than five per cent, which will help our customers increase their product quality and at the same time reduce their energy use.”

Ekebro explains: “That decision was quite easy for SCA to take. We have produced pulp on the site since 1932, we have all the infrastructure in place, and we have a lot of skilled people here – also, very importantly, it made good financial sense.” The expansion of Östrand comes
at a time of increasing demand for high-quality softwood pulp, which
is the preferred raw material of many tissue producers around the world. Arvid Eriksson, sales director for tissue at SCA, says, “Two things are key to our customers; they want to secure sufficient volumes of certified pulp and they want a top performing product where tensile strength is of particular importance. We do both.
A meticulously planned expansion Plans for expansion at Östrand had been on SCA’s agenda for some time. As long ago as 2004, a new recovery boiler was ordered from Andritz with a unique insistence; it had to be expandable for an imminent capacity increase. “There was never a question of
whether the Helios project would happen,” adds Ekebro. “It was always a case of when. We have been preparing for this expansion
for some time now. “When it came to the recovery boiler, we initially had it designed for higher steam pressure and better efficiency and also with an increased turbine capacity to enable us to produce much more electricity. Crucially, the housing had to be built with a movable wall so we could increase the capacity of the boiler exactly when we needed to.” After the recovery boiler’s
installation and start-up in 2006, the next logical step was a new lime kiln, also supplied by Andritz, which started up in 2011. At the time, this move sparked off discussions into the viability of doubling capacity of the mill and presentations were made to senior management at SCA, who found the content “very interesting”, says Ekebro. “But of course a major evaluation of the complete SCA value chain, 4
