Sustainable Converting
The UK benefits from Iggesund’s latest sustainable approach to converting
INCOME AND DIVERSIFICATION APPEAL TO UK FARMERS When Iggesund Paperboard’s Workington Mill in Cumbria, UK, took the decision to invest in a biomass boiler in order to switch its energy source from fossil fuels to biomass, it immediately began to plan for its future fuel needs. One project, Grow Your Income, aims to engage and interest local farmers to start growing willow to be delivered as biomass to the mill. The programme has been well received and is growing still. There are many benefits for local
farmers in Cumbria and the Borders, including a secure, long- term regular income and increased farm biodiversity. Working with farmers and landowners is the task of Neil Watkins (pictured), alternative fuels manager at Workington Mill. “We have to appreciate that this
takes time and involves major decisions,” he explains, summing up the four years he has worked with the project so far. “Investing in energy crops is a 20-year commitment so of course people want to feel they are doing the right thing. Interest is growing and the number of farmers planting new SRC willow crops is increasing.” So far the mill has received over
26,000 tonnes of willow chips added in to the fuel mix, which is more than expected early on in the project. It also has a growing list of farmers and landowners who are planning to plant willow within the Grow Your Income programme this year and in 2017. “And that only involves a small
fraction of the planted areas we’ve helped to create, because it takes three years to reach the first harvest,” adds Ulf Löfgren, the Mill’s managing director, who helped to initiate the whole project. “From 2016 onwards we’re expecting more volumes but we’ve already received more biomass from energy crops than we expected.” The project was launched due to
a dramatic shift in the energy supply at the Mill. The company invested £108 million to build a new biomass-fuelled CHP plant, which went online in March 2013. Overnight the mill’s fossil carbon emissions were reduced to zero. At the same time the mill’s need for pure biomass went up by 500,000 tonnes a year. The mill had already secured a suficient biomass supply for the next several years but wanted to plan for the long term. Iggesund saw the opportunity to develop a new source of biomass in
INCREASED PRODUCTION AND DEVELOPMENT FOR INCADA “More stable quality, increased production and totally new conditions”. Those were the aims when Iggesund Paperboard’s Workington Mill in Cumbria, UK (seen below), was given a major rebuild this spring. The oldest part of the board machine, the press section, was replaced with cutting-edge technology. The rebuild has increased the machine’s capacity by 20,000 annual tonnes and is a cornerstone for further quality improvement. “These are the immediate effects but in the longer term the new press
section means we have a more advanced platform for our continued development work, which will be decisive for our future competitiveness,” comments Bengt Löfroth, technical strategy oficer at Workington Mill. Today Iggesund is said to be the only remaining paperboard mill using virgin fibre in the British Isles. It has a high technological standard and is a
SRC energy crops. The company is part of the Holmen Group, one of Sweden’s biggest forest owners, therefore the combination of knowledge and resources for the harvesting of forest raw materials were readily available. On this basis the company
developed an offer to farmers. Iggesund takes responsibility for harvesting and transporting the crop, while also guaranteeing farmers a return on their investment, which is index linked during the contract period, currently 22 years. Iggesund Paperboard has been
one of Workington’s biggest employers since the end of the 1980s. Since 2000 the company has invested almost 200 million pounds to develop its paperboard manufacturing process. Three years ago Iggesund made one of its smaller investments over the years – it planted an energy crop on the 10 hectares of land surrounding the mill. The crop will be harvested for the first time this winter. “We’re keen to show people that
we believe in growing energy crops and we also want a demonstration facility so we can show visitors exactly how it’s done,” Watkins concludes. “And we’re counting on making a profit from it, too.”
good demonstration of paperboard’s environmental advantages over other materials. In 2013 the switch from fossil natural gas to using biomass as its energy source meant an instant reduction of fossil carbon emissions by 190,000 tonnes per year, the equivalent of taking 65,000 cars off the road. “We’re constantly looking for ways to become more eficient and save on
the resources we use,” Löfroth adds. “What we’ve just done now means that we will reduce our energy consumption by almost 10 per cent – which is an achievement in itself.” Incada is the folding box board produced at Workington. It is made of
virgin fibre and is built to have a stiffness that makes it a preferred packaging material among companies looking for good protection with low weight.
