Content• What animals are we talking about
• Key environmental issues
• Animal welfare
• Whole chain concept
• How to come to BAT:• housing systems• landspreading of manure
• Conclusions
Slide 4
Poultry:• Chicken laying hens and broilers
• (Turkeys, ducks and Guinea fowls)
Pigs:• Mating and gestating sows• Farrowing sows • Weaned piglets• Growers/finishers

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 11
Whole chain concept
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
Iron or plastic slatted floor
Deep pit
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: 2003Total 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
