Odour and VOC impact assessment and air quality monitoring program at a municipal solid waste landfill

The scope of this paper is to present and compare the results of (1) an extensive odour, VOC and H2S impact assessment, and (2) a complete odour, VOC and H2S air quality monitoring program at a municipal solid waste landfill (MSWL). This study was conducted over a year, with an unprecedented amount of cross-assessment techniques and data points on a 1.3 million tonnes per year MSWL. All potential landfill emission sources were characterized for odours, VOCs, CH4 and H2S using a set of over 150,000 onsite samplings & measurements. An air quality monitoring program included continuous odour, CH4 and H2S monitoring, a 12-day-frequency VOC sampling campaign, and a 24h/7d odour survey at the nearest receptors. This paper will present the standardized methodologies used and comparative results from each independent assessment program.

Municipal Solid Waste Landfills

Landfill mining is a prospective tool for the recycling of valuable materials (waste-to-material) and secondary fuel (waste-to-energy) from old, therefore more or less stabilised municipal solid waste landfills. The main target of Horizon 2020 ‘SMARTGROUND’ R&D was improving the availability and accessibility of data and information from both urban landfills and mining dumps through a set of activities to integrate all the data – from existing sources and new information retrieved with time progress – in a single EU database. Concerning urban landfills, a new sampling protocol was designed on the basis of the current Hungarian national municipal solid waste analysis standards, optimised for landfill mining. This protocol was then applied in a sampling campaign on a municipal solid waste landfill in Debrecen, Hungary. The composition and parameters of the landfilled materials were measured as a 12-year timescale. The total wet and dry mass of the valuable components possible for utilisation was estimated.

The aim of this study was to assess the microbiological and chemical air quality in a municipal solid waste landfill and its inhabited surroundings, in a particular context in which Romania struggles with the incapacity to comply with its environmental commitments. The research was conducted on a landfill near the capital Bucharest between November 2018 and September 2019. To evaluate the chemical (oxygen, carbon dioxide, methane, hydrogen sulfide, ammonia and carbon monoxide–MX6 iBrid™ Détector multigas) and microbiological (airborne bacteria and fungi–aspiration method) parameters, eight sampling points were established, located both on the perimeter of the landfill and within its surroundings. CO and CH4 were not detected in any of the sampling points, during the study period; O2 was in normal values 20.09–21.05%; CO2 had a maximum average concentration of 620 ± 215; H2S had values between 0.1 and 5.0 ppm only in the sampling points inside the landfill; NH3 was present only once in a single sampling point with values between 1.0 and 3.0 ppm. The microbiological results provide an overview of the total plate count and total fungal count, with no significant differences between the level of contamination inside the landfill and within its surroundings (p > 0.05). Ten bacterial species and fungi from six genera have been identified. It was also found that the number of microorganisms in the air was significantly lower during the winter, spring and early summer months compared with the late summer and autumn months (p < 0.05).
