Characterisation of odour masking agents often used in the solid waste industry for odour abatement.
Odours from waste management facilities, wastewater treatment plants and composting areas have become a major nuisance issue for operators. In addition to facing regulations which tend to become more stringent, operators are also facing increased public pressure due to complaints from neighbours resulting in the temporary shutdown of such plants, therefore the elimination of atmospheric odours is becoming a major industrial objective. Many commercial odour control products are available on the market, however, very little is known concerning their real efficiency and mechanism of action. This paper will present the results from the study of 19 agents collected in various countries. The products were first characterised both in terms of their chemical composition and sensory properties. Selected products with different modes of application were then submitted to a study of their efficiency at the pilot-scale level. The results from one product test showed no significant difference in their odour removal efficiency as determined by olfactory and chemical analysis of the emission before and after application of the odour control product.
