Piggeries have the potential to cause odour impacts and as such, odour is an important consideration at all stages of piggery planning, construction, and operation.

Accurate odour data and models are needed to accurately predict odour emissions, and as such, provide clarity during the planning and development of new or expanded piggeries. Additionally, ensuring piggeries are planned with correct odour and separation distances will reduce odour-related complaints from neighbours.

While current modelling uses the best available modelling practices, the models are largely reliant on data that is now over twenty years old and so may not accurately reflect odour in modern piggeries. This project set out to validate odour these modelling techniques and technologies.
