Iggesund’s fossil-free mill: The vision is within reach

/INS. “We’re getting close to the vision of a fossil-free mill that we’ve lived with and that has driven our investments for a long time,” says Mill Director Olov Winblad von Walter. “Our new recovery boiler, which came on line in spring 2012, is getting better and better as we fine tune it, and our increasing pulp production is also boosting our energy production.”

For a while in mid-April Iggesund Paperboard’s Swedish paperboard mill, Iggesund Mill, was able to operate solely on bioenergy and also supply almost all its own electricity needs. Another important aspect in the vision for Iggesund Mill is that emissions to air and water should be so low that Iggesund is among the global leaders among comparable manufacturers. Yet another goal is that a minimum of by-products will go to landfill.

Iggesund Mill is one of the world’s integrated paperboard mills with the highest level of investment. When it started up the new recovery boiler was the mill’s biggest investment to date, at a cost of about EUR 250 million. The boiler enabled the mill to gradually increase its annual pulp production from what was then 350,000 tonnes to 420,000.

“Our sulphate process for pulp production means that we separate out the cellulose fibres that comprise half the mass of a log,” Winblad von Walter continues. “The other half consists of the wood’s binding agent, which is mostly an energy-rich substance called lignin. We burn this in the recovery boiler and it produces enough steam and electricity to cover more than 90 per cent of our energy needs.”

A fossil-free energy supply is not the only benefit from Iggesund’s new recovery boiler. After the boiler had been fine tuned, it turned out that particle emissions from the mill, which were already low, had been halved. Sulphur emissions, which contribute to the acidification of surrounding land, have also fallen by more than 80 per cent from what were already low levels.

Just over a year ago Iggesund’s board mill in Workington, England, radically changed its own energy source. From having run on fossil natural gas, the mill switched to using biomass. Achieving this required the investment of about EUR 122 million in a new biofuel boiler. Today the mill operates solely on biofuel and in addition to covering its own energy needs it also supplies fossil-free electricity to the UK electricity grid.

“One of the goals driving our investments is long-term sustainability, and the investments in both Iggesund and Workington are the result of that approach,” explains Staffan Jonsson, head of Group Technology at the Holmen Group, to which Iggesund belongs.

The Holmen Group is one of the world’s 100 most sustainable companies according to the UN sustainability index, the Global Compact Index.

Iggesund

Iggesund Paperboard is part of the Swedish forest industry group Holmen, one of the world’s 100 most sustainable companies listed on the United Nations Global Compact Index. Iggesund’s turnover is just over €500 million and its flagship product Invercote is sold in more than 100 countries. The company has two brand families, Invercote and Incada, both positioned at the high end of their respective segments. Since 2010 Iggesund has invested more than €380 million to increase its energy efficiency and reduce the fossil emissions from its production.

Iggesund and the Holmen Group report all their fossil carbon emissions to the Carbon Disclosure Project. The environmental data form an integral part of an annual report that complies with the Global Reporting Initiative’s highest level of sustainability reporting. Iggesund was founded as an iron mill in 1685, but has been making paperboard for more than 50 years. The two mills, in northern Sweden and northern England employ 1500 people.

The Iggesund Mill

Making the world’s best paperboard is easy. You need water, carbon dioxide and sunlight to grow a seedling into a tree. Then you need sustainable forest management that can deliver first-class timber. There must be a pulp mill and a paperboard mill, and then distribution channels to get the paperboard to everyone who wants to use it. Most important of all, though, to the manufacture of Invercote are the skilled professionals who do their best – people who are proud of what they achieve and do not compromise on the quality of their work. Iggesunds Mill has traditions stretching back to 1685. Throughout that time dedicated individuals have done their utmost to use the renewable forest to benefit other people.

A world-class mill

Iggesund Mill (including Strömsbruk Mill) in Sweden is one of the most advanced, fully integrated pulp and paperboard mills in the world. Not least thanks to our long term majority owner, we have very well invested mills. There are many benefits having an integrated saw mill – we manage raw material together and we can use all the waste from their production to either make pulp or energy. In return we feed the saw mill with steam used to dry the timber. At Iggesund Mill, 100% of the pulp used to make Invercote is produced on location and pumped wet to the board machine. This means that we use no market pulp. Not drying the pulp preserves some mechanical properties of the fibres.

This advanced technology – hundreds of metres of paperboard machines – is controlled by employees with various forms of special expertise. The machines work around the clock and year round to produce tonne after tonne of dazzling white paperboard. Technical perfection and numerical control processes are all well and good but for excellent results you also need team spirit and a good working atmosphere. Invercote’s unique properties are the result of the interplay between expertise, a positive spirit and cutting-edge technology.

Actively investing in bioenergy

In 2012 the new recovery boiler was inaugurated at Iggesund Mill, an investment made possible by the long term perspective of our majority owner. With it in operation, the mill produces all the heat it needs, and can also provide district heating to the nearby community. It also produces nearly all the electricity needed for the mill, and is connected to the grid to be able to output excess electricity if needed. As the new boiler was trimmed into operation, it drastically reduced a lot of emissions between 2013 and 2014: fossil CO2 by >85%, particles by ~45% and sulphur by ~35%

With the installation and trimming of the new recovery boiler, emissions to air have reduced drastically from already low levels – graph being updated shortly. Measurements have shown that only 1% of particles in the air of Iggesund village comes from the mill. The majority of particles comes from domestic fire places and cars.

Care for our customers and their businesses

Paperboard must be there when the customer needs it. All the quality features in the world are meaningless if the deliveries don’t arrive in time. Delivery precision is a high priority. A maritime transport system guarantees overseas customers receive shipments with the lowest possible environmental impact. The service doesn’t stop there. Every tonne of Invercote comes with access to documentation and knowledge about how to make best use of the paperboard. The knowledge and market-based technical support provided by Iggesund, help customers to achieve dazzling end results and optimal production economics.
