“…All the landfills, which were described in more detail in previous studies (the Glatved landfill was also presented under the name of Reno Djurs), were still in service and at that time only received low-organic waste fractions for permanent disposal (Mou et al, 2014;Mønster et al 2015). They had different ages and provided waste data from various starting years of disposal until year 2012.…”

“…From 2006 to 2012, several field measurements of wholesite CH 4 emissions at the four Danish landfills (as well as at some specific landfill cells) were conducted using the tracer dispersion method (Scheutz et al, 2011a;Mønster et al, 2014Mønster et al, , 2015. In comparison to A values, measured results were used to test and to evaluate the applicability of the revised Afvalzorg model for Danish landfills receiving low-organic waste fractions.…”

“…However, these measurements have surface footprints that are too small to account for whole-site LFG emissions because the material disposed of at landfills and the areal emission pattern can hardly be considered homogeneous (Börjesson et al, 2000;Scheutz et al, 2009;Trégourès et al, 1999). Over the past decade, a tracer dispersion method has been developed and proved to be more reliable and reproducible than other measurement approaches (Abichou et al, 2010Galle et al, 2001;Goldsmith et al, 2012;Scheutz et al, 2011b); resent studies have established the method as a reliable and accurate approach for quantifying whole-site fugitive landfill CH 4 emissions (Mønster et al, 2014(Mønster et al, , 2015.…”

“…Whole-site fugitive CH 4 emissions at the same landfills were measured by applying the tracer dispersion method (Mønster et al, 2015). Based on actual waste data of four Danish landfills, annual and normalized CH 4 generations to the amount of disposed waste (kg CH 4 /ton waste) from the beginning of disposal until year 2020 and year 2100 at the four landfills were estimated by three FOD models (using both default and revised parameter values).…”

Methane (CH 4 ) generated from low-organic waste degradation at four Danish landfills was estimated by three first-order decay (FOD) landfill gas (LFG) generation models (LandGEM, IPCC, and Afvalzorg). Actual waste data from Danish landfills were applied to fit model (IPCC and Afvalzorg) required categories. In general, the single-phase model, LandGEM, significantly overestimated CH 4 generation, because it applied too high default values for key parameters to handle low-organic waste scenarios. The key parameters were biochemical CH 4 potential (BMP) and CH 4 generation rate constant (k-value). In comparison to the IPCC model, the Afvalzorg model was more suitable for estimating CH 4 generation at Danish landfills, because it defined more proper waste categories rather than traditional municipal solid waste (MSW) fractions. Moreover, the Afvalzorg model could better show the influence of not only the total disposed waste amount, but also various waste categories. By using laboratory-determined BMPs and k-values for shredder, sludge, mixed bulky waste, and street-cleaning waste, the Afvalzorg model was revised. The revised model estimated smaller cumulative CH 4 generation results at the four Danish landfills (from the start of disposal until 2020 and until 2100). Through a CH 4 mass balance approach, fugitive CH 4 emissions from whole sites and a specific cell for shredder waste were aggregated based on the revised Afvalzorg model outcomes. Aggregated results were in good agreement with field measurements, indicating that the revised Afvalzorg model could provide practical and accurate estimation for Danish LFG emissions. This study is valuable for both researchers and engineers aiming to predict, control, and mitigate fugitive CH 4 emissions from landfills receiving low-organic waste.Implications: Landfill operators use the first-order decay (FOD) models to estimate methane (CH 4 ) generation. A single-phase model (LandGEM) and a traditional model (IPCC) could result in overestimation when handling a low-organic waste scenario. Site-specific data were important and capable of calibrating key parameter values in FOD models. The comparison study of the revised Afvalzorg model outcomes and field measurements at four Danish landfills provided a guideline for revising the Pollutants Release and Transfer Registers (PRTR) model, as well as indicating noteworthy waste fractions that could emit CH 4 at modern landfills.

“…Elbir et al (2007) predicted odor levels' concentrations around a meat packaging and rendering plant using CALPUFF. Many other studies have successfully examined dispersion modeling in landfills (Leonardos 1996;Schiffman and Williams 2005;Ubeda et al 2010;Zhu et al 2013;Mønster et al 2015). Ubeda et al (2010) examined the impact of the odor from a landfill and waste treatment facility through the application of two dispersion models: geographic information system (GIS) tools and a commercial bi-Gaussian atmospheric dispersion model.…”

This study used the CALPUFF modeling system to study the impact of an area's geophysical and meteorological conditions on the dispersion of nonmethane organic compounds (NMOCs) into the atmosphere from the 17-year-old Barka Landfill. Barka Landfill is located in Barka, Batinah, in the north of the Sultanate of Oman. It receives waste from nearby regions such as Nakhal, Seeb, and Wadi Al-Maawel, affecting the town of Barka with landfill gas (LFG) pollution. The present study was conducted to evaluate the impact of the air dispersion of one group of NMOC gases on Barka and the region around it. The top five values of the concentrations with different average time periods, namely 1, 3 and 23 h, were compared with the allowable emission rate defined by the US Environmental Protection Agency (EPA). The results demonstrated that the present integrated modeling system (consisting of a 3D diagnostic CALMET model and Lagrangian puff dispersion CALPUFF model) could be utilized as a useful tool for evaluating the top five peak values of the NMOC emissions of the different time periods.
