| Tiivistelmä: | This paper provides a case study of the Delphi technique by undertaking a three-round Delphi study to determine a package of best available techniques to reduce nitrogen emissions from a poultry unit under the Integtrated Pollution Prevention and Control Directive (IPPC). Forms of nitrogen addressed included ammonia, nitrous oxide, nitrogen oxides, dusts and nitrate, with the study providing a means to prioritise the pollution concerns of different spatial scales. The study indicated the need for abatement techniques at each stage of poultry rearing and waste management, with particular attention to reduce ammonia emissions, reflecting the priority pollutant concerns. The authors conclude that uncertainties in the Delphi technique limit its suitability as a stand-alone decision making tool. However, the technique proved useful in identifying priority pollutant issues, areas of agreement, disagreement and where information is lacking. |
