Abstract	Odour emissions are a major environmental issue, in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time and the climatic conditions, as well as the subjectivity of the odour perception are the elements that have delayed their regulation. For this reason there are few international laws that set the limits of odour emissions from industrial sources and/or define the criteria of quality related to the smell. In particular, there are currently no regulations that deal with this problem in Italy. Analytical techniques such as the use of surrogate chemical markers (i.e. H2S or NH3) as well as the chemical analysis of odorous mixtures by chromatographic techniques (i.e. GC-MS) can be used for continuous assessment, but are limited due to usually being compound specific, which may not always relate to olfactory perception. Whereas olfactory assessment offers an accurate measurement of olfactory annoyance. However, the cost, potential subjectivity and time restrictions (due to being laboratory based) make them unsuitable for continuous assessment in terms of air quality monitoring. In this study, a novel tool based on a highly innovative on-site analytical instrument (Portable GC-MS Hapsite, Inficon) was used to identify and characterize the volatile substances that cause odour annoyance and the main sources in a composting plant. At the same time, this work identified odours key compounds and investigated the relationship between their concentration measured by GC-MS analysis and the performances of the plant. The main chemical substances responsible for the olfactory annoyances were also identified. In conclusion, odour abatement system (static biofilter) efficiency was tested in terms of reduction of both key compounds and quality composition clean gas. The results highlight the applicability of this tool in directly monitoring odour emissions in terms of air pollution management. 38 different substances are detected; of these almost half were found to be smell relevant components and the ones responsible for the typical smell of composting plants. Limonene and 2-Butanone are identified as key compounds connected to the specific production process.
