Slide 8 Farm activities: Farm management Feeding strategy Rearing of animals: housing systems Collection and storage of manure On-site treatment of manure Landspreading of manure
Slide 9 Key environmental issues Emissions to: air (ammonia) soil and groundwater (N, P) Energy and water Waste
Slide 10 Animal welfare Water for the animals Housing systems cages versus free range systems for laying hens litter based systems for pigs materials for enrichment for pigs and chickens light, heating/cooling, ventilation, ….
Slide 12 How to come to BAT How to come from Chapter 4 Chapter 5 A tool for the BAT-assessment Reference system (few data + climate conditions) Applied for assessing: housing systems for pigs housing systems for layers and broilers air abatement systems in housings
Slide 14 Housing systems; pigs Reduce manure pit Remove manure Flush with liquid part Cool manure surface Use smooth surfaces
Slide 15 Housing systems; pigs The conclusions in Chapter 5: BAT Conditional BAT; odour BAT for systems that are already in place Split view from one Member State Littered systems
Slide 16 Housing systems; laying hens Conventional cage housing: Ban on new: 2003 Total ban: 2012
Slide 17 Housing systems; laying hens The conclusions in Chapter 5: Conventional cage housing BAT: quick removal of manure quick removal and drying of manure Conditional BAT
Slide 18 Housing systems; laying hens The conclusions in Chapter 5: Enriched cage concept is the only alternative BAT assessment not possible Non-cage housing BAT, although higher ammonia and dust emissions
Slide 19 Housing systems; broilers Reference: simple closed building with litter; no cage The conclusions in Chapter 5: BAT Conditional BAT; the Combideck system BAT for systems that are already in place
Slide 20 Landspreading of slurry BAT for applying slurry to arable land: Injection Bandspreading + incorporation < 4 hours
Slide 21 Landspreading of slurry Split view: Bandspreading with / without incorporation Not BAT: Conventional broadcasting No consensus on: Improved broadcasting + incorporation
Slide 22 Landspreading of solid manure BAT for applying solid manure - from pig and poultry - to arable land: Incorporation < 12 hours Split view on pig and poultry manure: Incorporation < 24 hours
Slide 23 Conclusions The TWG reached a high degree of consensus on the BREF document and on the BAT-conclusions Five split views were reported A useful document for the permitwriter The Province of Zeeland is offering you practical help in your permitwriting processes
Slide 24 Conclusions A whole new ‘living’ area for the EIPPCB
