Division DEFINITIONS

United Kingdom

For the purpose of these BAT conclusions, the following definitions apply:

Term used	Definition
New plant	A plant first permitted on the site of the installation following the publication of these BAT conclusions or a complete replacement of a plant on the existing foundations of the installation following the publication of these BAT conclusions.
Existing plant	A plant which is not a new plant.
Major refurbishment	A major change in design or technology of a plant/abatement system and with major adjustments or replacements of the process units and associated equipment.
New dust abatement system	A dust abatement system first operated on the site of the installation following the publication of these BAT conclusions.
Existing dust abatement system	A dust abatement system which is not a new dust abatement system.
Non-condensable odorous gases (NCG)	Non-condensable odorous gases, referring to malodorous gases of kraft pulping.
Concentrated non-condensable odorous gases (CNCG)	Concentrated non-condensable odorous gases (or ‘strong odorous gases’): TRS-containing gases from cooking, evaporation and from stripping of condensates.
Strong odorous gases	Concentrated non-condensable odorous gases (CNCG).
Weak odorous gases	Diluted non-condensable odorous gases: TRS-containing gases which are not strong odorous gases (e.g. gases coming from tanks, washing filters, chip bins, lime mud filters, drying machines).
Residual weak gases	Weak gases that are emitted in ways other than through a recovery boiler, a lime kiln or a TRS-burner.
Continuous measurement	Measurements using an automated measuring system (AMS) permanently installed on site.
Periodic measurement	Determination of a measurand (particular quantity subject to measurement) at specified time intervals using manual or automated methods.
Diffuse emissions	Emissions arising from a direct (non-channelled) contact of volatile substances or dust with the environment under normal operating conditions.
Integrated production	Both pulp and paper/board are produced at the same site. The pulp is normally not dried before paper/board manufacture.
Non-integrated production	Either (a) production of market pulp (for sale) in mills that do not operate paper machines, or (b) production of paper/board using only pulp produced in other plants (market pulp).
Net production	(i) For paper mills: the unpacked, saleable production after the last slitter winder, i.e. before converting. (ii) For off-line coaters: production after coating. (iii) For tissue mills: saleable production after the tissue machine before any rewinding processes and excluding any core. (iv) For market pulp mills: production after packing (ADt). (v) For integrated mills: Net pulp, production refers to the production after packing (ADt) plus the pulp transferred to the paper mill (pulp calculated at 90 % dryness, i.e. air dry). Net paper production: same as (i)
Speciality paper mill	A mill producing numerous paper and board grades for special purposes (industrial and/or non-industrial) that are characterised by particular properties, relatively small end use market or niche applications that are often especially designed for a particular customer or end-user group. Examples of speciality papers include cigarette papers, filter papers, metallised paper, thermal paper, self-copy paper, sticking labels, cast coated paper, as well as gypsum liners and special papers for waxing, insulating, roofing, asphalting, and other specific applications or treatments. All of these grades fall outside of the standard paper categories.
Hardwood	Group of wood species including e.g. aspen, beech, birch and eucalyptus. The term hardwood is used as opposite to softwood.
Softwood	Wood from conifers including e.g. pine and spruce. The term softwood is used as opposite to hardwood.
Causticising	Process in the lime cycle in which hydroxide (white liquor) is regenerated by the reaction Ca(OH)₂ + CO₃ ^2– → CaCO₃ (s) + 2 OH^–
