Control of Odour and Dust from Chicken Sheds: Evaluation of windbreak walls

Abstract

Odour from tunnel ventilated broiler sheds has the potential to cause odour impacts. Meat chicken
producers are under pressure to reduce odour impacts and need cost-effective solutions. Windbreak walls have been proposed as an affordable technology that may improve the dispersion of odours from tunnel ventilated broiler sheds, in turn reducing odour impacts. Unfortunately, the actual efficacy of windbreak walls to improve dispersion has not been properly assessed.
This research was important because of a growing need to increase knowledge and improve understanding of windbreak walls for enhancing dispersion from tunnel ventilated sheds. This need was being driven by pressure on the chicken meat industry to adopt odour control technologies/practices, and a lack of evidence to support the theoretical efficacy of windbreak walls.
