Division DEFINITIONS AND ACRONYMS
United Kingdom
For the purpose of these BAT conclusions, the following definitions apply:
| Term | Definition |
|---|---|
| COD | Chemical oxygen demand; the amount of oxygen needed for the total oxidation of the organic matter to carbon dioxide (normally in reference to analysis with dichromate oxidation). |
| Continuous measurement | Continuous determination of a measurand using a permanently installed ‘automated measuring system’ (AMS) or ‘continuous emission monitoring system’ (CEM). |
| Continuous press | A panel press that presses a continuous mat. |
| Diffuse emissions | Non-channelled emissions that are not released via specific emission points such as stacks. |
| Directly heated dryer | A dryer where hot gases from a combustion plant, or any other source, are in direct contact with the particles, strands or fibres to be dried. The drying is achieved by convection. |
| Dust | Total particulate matter. |
| Existing plant | A plant that is not a new plant. |
| Fibre | Lignocellulosic components of wood or other plant materials derived by mechanical or thermo-mechanical pulping using a refiner. Fibres are used as the starting material for the production of fibreboard. |
| Fibreboard | As defined in EN 316 i.e. ‘panel material with a nominal thickness of 1,5 mm or greater, manufactured from lignocellulosic fibres with application of heat and/or pressure’. Fibreboards include wet process boards (hardboard, medium board, softboard) and dry-process fibreboard (MDF). |
| Hardwood | Group of wood species including aspen, beech, birch and eucalyptus. The term hardwood is used as an opposite to the term softwood. |
| Indirectly heated dryer | A dryer where the drying is exclusively achieved by radiation and conduction heat. |
| Mat forming | The process of laying out particles, strands or fibres to create the mat, which is directed to the press. |
| Multi-opening press | A panel press that presses one or more individually formed panels. |
| New plant | A plant first permitted at the site of the installation following the publication of these BAT conclusions or a complete replacement of a plant following the publication of these BAT conclusions. |
| NOX | The sum of nitrogen oxide (NO) and nitrogen dioxide (NO2), expressed as NO2. |
| OSB | Oriented strand board, as defined in EN 300 i.e. ‘multi-layered board mainly made from strands of wood together with a binder. The strands in the external layer are aligned and parallel to the board length or width. The strands in the internal layer or layers can be randomly orientated or aligned, generally at right angles to the strands in the external layers’. |
| PB | Particle board, as defined in EN 309 i.e. ‘panel material manufactured under pressure and heat from particles of wood (wood flakes, chips, shavings, saw-dust and similar) and/or other lignocellulosic material in particle form (flax shives, hemp shives, bagasse fragments and similar), with the addition of an adhesive’. |
| PCDD/F | Polychlorinated dibenzo-dioxins and -furans |
| Periodic measurement | Measurement at specified time intervals using manual or automated reference methods. |
| Process water | Waste water derived from processes and activities within the production plant, excluding surface run-off water. |
| Recovered wood | Material predominantly containing wood. Recovered wood can consist of ‘reclaimed wood’ and ‘wood residues’. ‘Reclaimed wood’ is a material predominantly containing wood derived directly from post-consumer recycled wood. |
| Refining | Transforming wood chips into fibres using a refiner. |
| Roundwood | A wood log. |
| Softwood | Wood from conifers including pine and spruce. The term softwood is used as an opposite to the term hardwood. |
| Surface run-off water | Water from precipitation run-off and drainage, collected from outdoor log yard areas, including outdoor process areas. |
| TSS | Total suspended solids (in waste water); mass concentration of all suspended solids as measured by filtration through glass fibre filters and gravimetry. |
| TVOC | Total Volatile Organic Compounds, expressed as C (in air). |
| Upstream and downstream wood processing | All active handling and manipulation, storage or transport of wood particles, chips, strands or fibres and of pressed panels. Upstream processing includes all wood processing from the point that the wood raw material leaves the storage yard. Downstream processing includes all processes after the panel leaves the press and until the raw panel or the value-added panel product is directed to storage. Upstream and downstream wood processing do not include the drying process or the pressing of panels. |
