Odour impact assessment of a large municipal solid waste landfill under different working phases

Abstract

<p>Odours are among the main causes of complaints in regards to environmental issues for a variety of plants, including landfills. The emissions from landfills can affect the quality of life and negatively influence the area nearby. To protect people living in the surroundings from excessive odour exposures, different environmental protection practices may be implemented. In order to optimize technical and economic aspects, various configurations should be taken into account. In this view, the odour dispersion modelling represents a suitable tool to simulate different scenarios. In the present study, the odour impact from a large landfill located in Borgo Montello (Lazio Region, Italy) has been assessed by a dispersion model. Different operating conditions were simulated, in view of minimizing the odour annoyance during the phase of temporary closure of an area of the investigated plant. The Calpuff model was selected as it is well recognized among the preferred models for assessing the long range transport of pollutants. The Odour Emission Rates, inputs to the model, were calculated based on the results of dynamic olfactometry. The outputs from the dispersion model were investigated to define the best measures for the control of the odour emissions during the most impactful operations.</p>

Electronic Noses and Their Applications for Sensory and Analytical Measurements in the Waste Management Plants—A Review

“…It was concluded that the landfill is mainly responsible for odor nuisance caused by the plant and that closing this particular odor source will significantly improve air quality nearby. Indeed, dynamic olfactometry in combination with dispersion models is a useful tool for the optimization of odor mitigation strategies [55], but a great care must be taken when developing these models as recent studies suggest that modeling choices may lead to a variance in the resulting odor concentrations at receptors differing by up to a factor 3 [56].…”

“…The operation of municipal waste landfills has negative impact on the environment through, among others, the emission of pollutants into the air. The available literature includes a number of studies on these issues (Capelli and Sironi 2018, Cheng et al 2020, Cheng et al 2019, Duan et al 2021, Fang et al 2012, Forastiere et al 2011, Giusti 2009, Heyer et al 2013, Jiang et al 2021, Ko et al 2015, Le Bihan et al 2020, Liu et al 2019, Long et al 2017, Lou et al 2015, Lucernoni et al 2016, Meišutovič-Akhtarieva and Marčiulaitienė 2017, Naddeo et al 2018, Sonibare et al 2019, Tagliaferri et al 2020, Yao et al 2019, Zhang et al 2021. The main cause of the emission of odor-generating substances from landfills is municipal waste deposited in a landfill, which undergoes three main processes: biodegradation of the organic substance contained in the deposited waste (biogenics), direct volatilization of compounds (xenobiotics), and biological or chemical reactions between waste contained in the deposit and reaction products (Duan et al 2021).…”
