Odour monitoring in an anaerobic digestion plant

In the latest years the problem of odour emissions has got an increasing emphasis, due to the expansion of urban areas with the consequent approach of the settlements to the industrial areas and the increase of public awareness towards environmental issues. Odours do not cause toxic effects to human health. However they can cause symptoms in both physiological (as respiratory problems, nausea and headaches) and psychological levels. In this article, the results of odour monitoring emissions in an anaerobic digestion plant fed with dedicated crops in which there is a feeding/mixing tank uncovered are presented. The role of this tank concerning the odour emissions is the object of the paper.
