Feedlot Odour Modelling R&D Workshop

Odour emissions from feedlots have been a contentious issue for many years and consequently, the subject of significant research. Despite this research, there is a paucity of reliable, quantitative data, measured using acceptable standards, on odour emissions arising directly from beef cattle feedlots. In 2003, it was recognised that recent changes in technology, standards and regulatory guidelines made the need to obtain more reliable and robust data on feedlot odour emissions imperative. The FLOT.323 project was called ‘Development of odour performance criteria for the Australian feedlot industry’ and it was completed in 2004. There were some uncertainties in the conclusions of that study. This uncertainty negated any adoption of the methodology by the state regulatory agencies.

Reviews of the project by two odour modelling experts were undertaken in 2007. These reviews delivered some useful suggestions and identified scope for some additional work and data analysis that could potentially enhance the value of the project. However, after these reviews were completed, the project lost momentum and nothing has happened in the past four years. This new project revisited the outcomes of the original odour project along with the outcomes of the reviews, within the context of the current regulatory environment and thinking on odour measurement and assessment techniques. The process involved an expert’s workshop, held on the 13th May 2011, which engaged the main consultants and researchers working in the feedlot odour modelling area. The outcome of the workshop was recommendations on a program of work that can be implemented to address the identified shortcomings in the original project.
