  "text": "In order to reduce dust emissions from each animal house, BAT is to use one or a combination of the techniques given below.\nA description of the techniques is given in Sections 4.3 and 4.11.\nTechnique\nApplicability\na\nReduce dust generation inside livestock buildings. For this purpose, a combination of the following techniques may be used:\n1.\n1.\nUse coarser litter material (e.g. long straw or wood shavings rather than chopped straw);\nLong straw is not applicable to slurry-based systems.\n2.\nApply fresh litter using a low-dust littering technique (e.g. by hand);\nGenerally applicable.\n3.\nApply ad libitum feeding;\nGenerally applicable.\n4.\nUse moist feed, pelleted feed or add oily raw materials or binders in dry feed systems;\nGenerally applicable.\n5.\nEquip dry feed stores which are filled pneumatically with dust separators;\nGenerally applicable.\n6.\nDesign and operate the ventilation system with low air speed within the house.\nApplicability may be limited by animal welfare considerations.\nb\nReduce dust concentration inside housing by applying one of the following techniques:\n1.\nWater fogging;\nApplicability may be restricted by the animal sensation of thermal decrease during fogging, in particular at sensitive stages of the animal's life, and/or for cold and humid climates.\nApplicability may be also restricted for solid manure systems at the end of the rearing period due to high ammonia emissions.\n2.\nOil spraying;\nOnly applicable to poultry plants with birds older than around 21 days. The applicability to plants for laying hens may be limited due to the risk of contamination of the equipment present in the shed.\n3.\nIonisation.\nMay not be applicable to pig plants or to existing poultry plants due to technical and/or economic reasons.\nc\nTreatment of exhaust air by an air cleaning system, such as:\n1.\nWater trap;\nOnly applicable to plants with a tunnel ventilation system.\n2.\nDry filter;\nOnly applicable to poultry plants with a tunnel ventilation system.\n3.\nWater scrubber;\nThis technique may not be generally applicable due to the high implementation cost.\nApplicable to existing plants only where a centralised ventilation system is used.\n4.\nWet acid scrubber;\n5.\nBioscrubber (or biotrickling filter);\n6.\nTwo-stage or three-stage air cleaning system;\n7.\nBiofilter.\nOnly applicable to slurry-based plants.\nA sufficient area outside the animal house is needed to accommodate the filter packages.\nThis technique may not be generally applicable due to the high implementation cost.\nApplicable to existing plants only where a centralised ventilation system is used.",
