Complaints due to odour annoyance have become a major issue for wastewater treatment plant, waste management, landfill, intensive livestock and other industrial operators as the repeated release of unpleasant odorous emissions can constitute a nuisance to a local population. Traditionally, odour management has been maintained by the use of buffer distances between industry and receptors or by the installation of odour abatement systems that both collect and disperse the emission or treat the emission to acceptable level to limit receptor impact. With the expansion of suburbia and the associated encroachment, residents and industry are coming into closer proximity than in the past. This interaction is unpredictable, complex and difficult to address. Integrated odour impact management approaches involving improved measurement and understanding of odorous emissions, their impact on local receptors, treatment performance and integration in local community relations programs are needed to meet the potential impact due to population growth and increasing global urbanisation.
