“It always takes time to fine tune a new piece of equipment and we’ve also made some smaller investments to optimise our return from the recovery boiler,” explains Olov Winblad von Walter, Manager of Iggesund Mill. “Now we’re getting close to achieving the potential we expected.”
The mill’s environmental improvements are not limited to carbon dioxide. Emissions of sulphur have also been cut by 82%, nitrogen oxides by 19% and particulates by 90% – all compared with 2011, which was the last year the old recovery boiler was operating. A conscious decision on operating strategy and investments in process stages that previously used fossil fuel oil have also contributed to the radical reductions in air-borne emissions.
Iggesund Mill is not the only component of the Holmen Group to succeed with its environmental work. Between 2013 and 2014 carbon dioxide emissions per tonne of manufactured paperboard and paper products within the Group were cut from 123 kilos to 67 kilos. This is almost 50 per cent and demonstrates clearly that the Group has taken yet another step to reduce the climate impact of its own operations.
