The product 'sulfate pulp, bleached', also called bleached kraft pulp, is a type of bleached, chemical, wood-containing pulp. It represents Elemental Chlorine Free (ECF) and Totally Chlorine Free (TCF) kraft pulp. The product bleached sulfate pulp represents a mix of softwood pulp, hardwood pulp and eucalyptus pulp. Softwood pulp is made from coniferous trees, most typically from different species of pine and spruce. Hardwood pulp is made from non-coniferous trees, in Nordic countries primarily of birch. Eucalyptus hardwood pulp is made exclusively of eucalyptus species. Sulfate pulp fibres from softwood fibres are long and slender and are used to give the paper and board products their strength properties. Sulfate pulp fibres from hardwood short and can be rounder and their number per gram of pulp is much larger; they give the end product its smoothness, softness and optical properties like opacity. The pulp, or fibres from the wood are separated in a kraft cooking process in a so-called fibre line. In a recovery line, the chemicals used in the cooking process are recovered to be used again and energy is produced. The third process is effluent treatment where gaseous and liquid discharges to the environment are continuously minimized and monitored. Bleached sulfate pulp is used for the production of tissue (toilet paper), graphic papers , specialty products, packaging, fluff pulp, viscose, and CMC.
