“…This finding indicates that the pilot-scale biocover boxes performed very well and were able to oxidize most of the injected methane in the spring, summer and fall, but not the winter. These results are consistent with the reported methane removal efficiencies byDuan et al (2022) andNelson et al (2022).…”

This research investigated the performance of biocover materials in mitigating methane emissions through column experiments, pilot-scale testing, and numerical simulation.Laboratory column experiments were used to evaluate the impact of different CH4 loading rates on the performance of biocover materials, including food waste compost, yard waste compost, and peat moss in reducing methane emissions. In the second part of the research study, the methane removal performance of two biocover materials (i.e., food and yard waste composts) were examined under different temperature conditions using laboratory column experiments. A numerical model was also validated and used to develop a better understanding of the material properties, gas transport mechanisms, CH4 oxidation processes, and overall impact on methane removal efficiency under different CH4 loading rates and temperatures. In the third part, the performance of different biocover materials, including food waste compost and yard waste compost, in mitigating methane emissions was investigated using outdoor pilot-scale biocover systems exposed to seasonal temperature variations over a 400-day period in Ottawa, Canada. Results of this study indicated that the CH4 removal efficiency in the column tests at 22°C was greater than 96.6% when the loading rate was below 96 g m -2 day -1 . It was also found that the oxidation rate was affected by temperature as the CH4 removal efficiency at 8 o C decreased by 70% of CH4 removal efficiency at 22 o C. The pilot-scale test also proved that CH4 removal efficiency was influenced by seasonal temperature variations as the removal efficiency was limited during the winter season, but it approached to 100% CH4 removal in the summer season at a CH4 loading rate of 45 g m -2 day -1 . The findings also indicated that the oxidation capacity was limited not only by the maximum CH4 oxidation rate, but also the biocover PrefaceThe work reported in this PhD thesis, entitled "Performance of Different Biocover Materials in Mitigating Methane Emissions from Landfills in Cold Climates", was conducted at the Department of Civil and Environmental Engineering at Carleton University with Professors Mohammad Rayhani, Paul Van Geel, and Cole Van De Ven as co-supervisors. The content of the PhD thesis follows an integrated format, where the main works are presented as three papers prepared for scientific journals.

“…Waste management is nevertheless regulated in the EU (Scheutz et al, 2009;Bourn et al, 2019;Fjelsted et al, 2019;Daugėla et al, 2020), and net land waste disposal emissions decreased by 46 % between 1990(European Environment Agency, 2020, primarily through diverting organic waste away from storage in landfills (European Commission, 2020). Landfill emission mitigation is gaining traction (Mønster et al, 2019;Bogner et al, 2008) by curtailing organic waste reaching landfills (Shams et al, 2017) and by recuperating the methane produced on site as biogas (Scheutz et al, 2009;Duan et al, 2021). Although landfill biogas can be flared (Tratt et al, 2014), biogas collection and use for heat and electricity production is being implemented more and more (Bogner et al, 1995;Riddick et al, 2018;Themelis and Ulloa, 2007).…”

Abstract. Landfills are a significant source of fugitive methane (CH4) emissions, which should be precisely and regularly monitored to reduce and mitigate net greenhouse gas emissions. In this study, we present long-term, in situ, near-surface, mobile atmospheric CH4 mole fraction measurements (complemented by meteorological measurements from a fixed station) from 21 campaigns that cover approximately 4 years from September 2016 to December 2020. These campaigns were utilized to regularly quantify the total CH4 emissions from an active landfill in France. We use a simple atmospheric inversion approach based on a Gaussian plume dispersion model to derive CH4 emissions. Together with the measurements near the soil surface, mainly dedicated to the identification of sources within the landfill, measurements of CH4 made on the landfill perimeter (near-field) helped us to identify the main emission areas and to provide some qualitative insights about the rank of their contributions to total emissions from the landfill. The two main area sources correspond, respectively, to a covered waste sector with infrastructure with sporadic leakages (such as wells, tanks, pipes, etc.) and to the last active sector receiving waste during most of the measurement campaigns. However, we hardly managed to extract a signal representative of the overall landfill emissions from the near-field measurements, which limited our ability to derive robust estimates of the emissions when assimilating them in the atmospheric inversions. The analysis shows that the inversions based on the measurements from a remote road further away from the landfill (far-field) yielded reliable estimates of the total emissions but provided less information on the spatial variability of emissions within the landfill. This demonstrates the complementarity between the near- and far-field measurements. According to these inversions, the total CH4 emissions have a large temporal variability and range from ∼ 0.4 to ∼ 7 t CH4 d−1, with an average value of ∼ 2.1 t CH4 d−1. We find a weak negative correlation between these estimates of the CH4 emissions and atmospheric pressure for the active landfill. However, this weak emission–pressure relationship is based on a relatively small sample of reliable emission estimates with large sampling gaps. More frequent robust estimations are required to better understand this relationship for an active landfill.
