Dictionary
Here you can find descriptions of abbreviations and terms that occur in the paper industry.
AOX
Absorbable organic halogens.
BEK
Bleached Eucalyptus Kraft pulp.
BHKP
Bleached Hardwood Kraft Pulp.
BOD
Biological Oxygen Demand, biological method for measuring oxygen-demanding substances.
Bulk
Volume, inverted value for density expressed as cm3/g.
COD
Chemical Oxygen Demand. Chemical method for measuring oxygen-demanding substances
CTMP
Chemi-Thermo-Mechanical Pulp. Development of TMP, where the mechanical pulp is impregnated with chemicals. Stronger than TMP. The term is used in Europe for both bleached and unbleached pulp.
ECF
Elemental Chlorine Free. Sulphate pulp bleached using chlorine dioxide, instead of chlorine gas.
EPIS
European Pulp Industry Sector.
SCM UB
Timber measured under bark, used to measure raw timber.
CHEMICAL PULP
Paper pulp produced by boiling raw timber with chemicals. The pulp can be bleached to a higher brightness and a higher strength than mechanical pulp. Chemical pulp is usually sulphate pulp, but can also be sulphite pulp.
Latency
The deformed condition of pulp fibre.
Lignin
Polymer compound consisting mainly of phenylpropane units; the main binding agent for wood fibre. It comprises about 1/3 of the wood.
MECHANICAL PULP
Pulp produced using a mechanical process for fibre separation and processing. Has a higher level of bulk, stiffness and opacity than chemical pulp. Groundwood pulp, TMP and CTMP/BCTMP are types of mechanical pulp.
LWC
Light Weight Coated. A type of coated paper often used for catalogues and magazines.
NBSK
Northern Bleached Softwood Kraft: bleached longfibre sulphate pulp. The leading indicator of world market prices.
Norscan
Canada, the United States, Sweden and Finland.
NUTRIENT SALTS

Opacity
Degree of opaqueness.
GROUNDWOOD PULP (SGP)
Mechanical pulp based on roundwood as a raw material.
SHIVES CONTENT
Proportion of unseparated fibres found in the pulp.
SULPHATE
Method for producing chemical pulp.
SULPHITE
Like sulphate, but using a different cooking technique, different chemicals and with a different chemical recovery.
TCF
Totally chlorine-free bleached sulphate pulp.
TMP
Thermo-Mechanical Pulp: mechanical pulp produced using a technique in which the chips are preheated with steam, but without chemicals.
ULWC
Ultra Light Weight Coated. Similar to LWC but with a lower grammage.
UKP
Unbleached Kraft Pulp, unbleached sulphate pulp.
GRAMMAGE
Weight of paper per surface unit, expressed as g/m2.
