Ensuring that raw materials are efficiently utilized from the start is just as important as recycling. Consequently, resource-economical production is a key concept.
From one tree trunk from SCA’s forest, a full 95% is used, either for products or energy. Since SCA owns sawmills, pulp and paper mills, and manufactures forest-based biofuel, all interact in one efficient system. All grades of wood are used and every part of a tree can be utilized.
The manufacturing processes used are efficient. Wood losses are minimal and residual products are utilized nearly 100%. Wood chips from sawmills become raw material for the pulp mill, while bark and shavings are used as fuel. Residual products from the pulp mills, primarily bark and liquors, also become fuel and are responsible for a large portion of the mill’s own energy requirements.
100% of a tree is used:
36% becomes pulp and paper
23% becomes energy for pulp mill
20% becomes wood products
16% becomes energy to, e.g. heat homes
5% logging residues
