Intensive animal production presents many challenges to environmental management, both for animal producers and for government personnel charged with environmental protection. Potential emissions of pollutants to the atmosphere, soil and water may emanate from a variety of sources at the site of production facilities, as well as from off-site areas, such as agricultural land on which manure is applied. The European Union's "IPPC Directive" (EU 96/61/EC) requires integrated pollution prevention and control by a variety of industries including pig and poultry producers. IPPC must be achieved through the use of "best available techniques" (BAT). Through a comprehensive literature review, onsite examinations, and consultations with international experts and producers, we developed a list of candidate BAT for the Irish pig and poultry producers that must comply with EU 96/61/EC. These techniques include, among other things, environmental management systems (EMS), feed modification, rapid removal of manure from production facilities, and biofiltration for ammonia and odour control. Except for siting criteria and the implementation of an EMS, which should be adopted by all producers, candidate BAT are a set of techniques from which producers may choose to achieve environmental goals. The techniques are organised according to major production steps.
