GC–MS/O methodologies are broadened to improve ecological validity.
A Community Odour Wheel for untrained individuals is implemented.
A combined online and workshop based community engagement structure is proposed.
Common language between all stakeholders in environmental malodour provides many advantages.
A survey investigating the relationship between odour impact, wellbeing, odour observation, and perception, is implemented.
It was found that odour impact was determined by a small number of factors including distance, odour legislation, and odour annoyance.
Factors such as odour frequency also play a role in determining odour impact.
The implications of this research and the techniques used are discussed.
Odorous emissions from wastewater biosolids processing can cause nuisance impacts to the surrounding community. Odour Wheels are an effective tool for environmental odour management, but have yet to be provided for wastewater biosolids processing. Emissions throughout the biosolids processing from eight wastewater treatment plants, each with different unit operation configurations, were surveyed to identify odorants present and their olfactory properties. Chemical and olfactory methods identified a range of odorants and odours emitted throughout biosolids processing.
