  "text": "If on-farm processing of manure is used, in order to reduce emissions of nitrogen, phosphorus, odour and microbial pathogens to air and water and facilitate manure storage and/or landspreading, BAT is to process the manure by applying one or a combination of the techniques given below.\nA description of the techniques is given in Section 4.7.\nTechnique\nApplicability\na\nMechanical separation of slurry. This includes e.g.:\nScrew press separator;\nDecanter-centrifuge separator;\nCoagulation-Flocculation;\nSeparation by sieves;\nFilter pressing.\nOnly applicable when:\na reduction of nitrogen and phosphorus content is needed due to limited available land for manure application;\nmanure cannot be transported for landspreading at a reasonable cost.\nThe use of polyacrylamide as a flocculant may not be applicable due to the risk of acrylamide formation.\nb\nAnaerobic digestion of manure in a biogas installation.\nThis technique may not be generally applicable due to the high implementation cost.\nc\nUse of an external tunnel for manure drying.\nOnly applicable to manure from plants for laying hens. Not applicable to existing plants without manure belts.\nd\nAerobic digestion (aeration) of slurry.\nOnly applicable when pathogen and odour reduction is important prior to landspreading. In cold climates, it may be difficult to maintain the required level of aeration during winter.\ne\nNitrification-denitrification of slurry.\nNot applicable to new plants/farms. Only applicable to existing plants/farms when the removal of nitrogen is necessary due to limited available land for manure application.\nf\nComposting of solid manure.\nOnly applicable when:\nmanure cannot be transported for landspreading at a reasonable cost;\npathogen and odour reduction is important prior to landspreading;\nthere is enough space in the farm for windrows to be established.",
