From pine and groin to hard pieces of concentrated bioenergy;
Sawdust is transported from SCA's local sawmills to pellets plants. Tractors stack the sawdust and continuously feed the loading dock at the plant. The sawdust is then ground to a fine powder while hot flue gas is used to dry the material. The dried and finely ground powder is then pressed through a hole matrix and converted into pellets. When the pellets are pressed through the matrix they are about 100 degrees celsius. They are then cooled to suitable storage temperature. After storage, the pellets are screened and delivered to customers.
SCA's wood fuel pellets have values exceeding Class 1 from the Swedish Standards Institute and European Standard. The pellets are manufactured from FSC-certified sawdust. All consumer pellets are labelled with the Bra Miljöval eco-label. SCA is also certified to sell a certain volume of ENplus.
The Härnösand pellets plant is certified according to the ISO 14001 environmental management system and the ISO 50001 energy management system.
Pellets are an eco-friendly product and qualify as climate neutral. A domestic, renewable fuel that is part of nature's ecocycle and does not produce new carbon dioxide into the atmosphere.
SCA's pellets are moreover climate-smart, as production uses almost exclusively sustainable energy. The sawdust dryer in Härnösand is operated using bioenergy – the fine sawdust that was screened and set aside between storage and delivery. The electricity used in Härnösand and Stugun is from wind power, generated on SCA's own forest land. The pellets plant in Luleå is connected to SSAB and the drying process uses part of SSAB's local energy surplus, which means pellets can be manufactured with limited environmental impact.
Waste heat from the pellets plant in Härnösand is also delivered to the district heating grid.
All pellets transportation is optimized to minimize environmental impact.
