SCA invests in pellet mill to improve environmental performance
Since 1992, wood fuel pellets are produced at the Murbergsviken industrial site in Härnösand. In the drying process, terpenes and resin acids – natural substances in wood - are emitted. When vapour and particles are subject to sunlight, sometimes a refraction phenomenon occurs that makes the vapours look blueish and they may have an odd smell. “We now invest in new technology, a wet electrical filter, to better contain particles and thereby minimize the occasions when blue haze occurs”, says Per-Arne Persson, mill manager at SCA Bionorr.
