“…By contrast, the average SOAV of the gas emitted from the biowindow surface was 1586 uo E /m 3 , with a range of 297-4526 uo E /m 3 . The results achieved by the biofiltration systems are similar to those found by Lee et al (2018) [3], ranging between 95.4-99%, and Capanema et al, (2014) [12], showing a removal efficiency close to 100% even with a grate variability of odor inlet load.…”

“…Sulfur compounds had the highest RE value of 99.03% for biofilter and 98.88% for biowindows. These results are confirmed by Lee et al (2018) [3], which showed a great performance (98.8-99.1%) and concluded that biocovers had significantly high removal performances during all seasons. In terms of ORE, the results confirmed the high percentages found for the RE, as shown in Table 7.…”

“…The effect of the degradation of organic waste in landfills leads to landfill gas (LFG) emission, in particular methane (CH 4 ) and carbon dioxide (CO 2 ) [2]. In addition, non-methane volatile organic compounds (NMVOCs) and inorganic compounds lead to complaints from local citizens about the bad smells as well as health problems [3]. The NMVOCs include aliphatic compounds (alkanes and alkenes), aromatic hydrocarbons (benzene, toluene, ethylbenzene, etc.…”

“…Biofiltration systems are emerging technological solutions for the removal of methane and odors from LFG [13,14] when flaring is no longer feasible, which include different types, such as: biofilters [15,16]; biocovers [13,17,18]; and biowindows [17,19]; Based on previous small-scale studies [3,20], pilot scales of biocovers have been carried out to study methane removal [18,21,22]. In addition, studies on odor reduction [14,23] and simultaneous reduction of odors and methane [3,24,25] were also performed.…”

Biofiltration systems are emerging technological solutions for the removal of methane and odors from landfill gas when flaring is no longer feasible. This work analyzed and compared two full-scale biofiltration systems: biofilter and biowindows. The emission mitigation of methane, non-methane volatile organic compounds (NMVOCs) and odors during a two-year management and monitoring period was studied. In addition to diluted methane, more than 50 NMVOCs have been detected in the inlet raw landfill gas and the sulfur compounds resulted in the highest odor activity value. Both systems, biofilter and biowindows, were effective for the oxidation of methane (58.1% and 88.05%, respectively), for the mitigation of NMVOCs (higher than 80%) and odor reduction (99.84% and 93.82% respectively). As for the biofilter monitoring, it was possible to define the oxidation efficiency trend and in fact to guarantee that for an oxidation efficiency of 80%, the methane load must be less than 6.5 g CH4/m2h with an oxidation rate of 5.2 g CH4/m2h.

Land ll is an important anthropogenic source of greenhouse gases (GHG). Aiming at methane mitigation through the use of a cover layer in the form of fugitive emissions, this study investigated the methane passive bioxidation in a Brazilian land ll in bio lters under two conditions: control column (packing material using a 60 cm land ll cover soil with ≅0.8% organic matter) and enriched column (packing material using 45 cm land ll cover soil and 15 cm mixture of cover soil plus compost with ≅6% organic matter). The biogas was collected from a vertical drain pipe of a four-year-old cell and injected into the base of the columns with a high inlet loading (1000 g CH4 .m -².d -¹ at standard temperature and pressure conditions) in the upward ow mode. Ten campaigns were carried out for six months in order to determine the e ciency of the methane oxidation in each column. Parameters related to the biogas oxidation were also determined, such as soil temperature and moisture content and nutrients content in both lter beds. The oxidation global e ciencies were higher in the enriched column throughout all campaigns, with »71 and »95% for the control and enriched columns, respectively. Our study demonstrated that the use of substrates with high organic matter content and low cost (such as the compost) in land ll cover layers might present high e cacy in the reduction of methane fugitive emissions. Land ll is an important anthropogenic source of greenhouse gases (GHG). Aiming at methane mitigation through the use of a cover layer in the form of fugitive emissions, this study investigated the methane passive bio-oxidation in a Brazilian land ll in bio lters under two conditions: control column (packing material using only land ll cover soil with ≅0.8% organic matter) and enriched column (packing material using 45 cm land ll cover soil and 15 cm mixture of cover soil plus compost with ≅6% organic matter). Biogas was collected from a vertical drain pipe of a four-year-old cell and injected into the base of the columns with a high inlet loading (1000 gCH4.m-².d-¹) in upward ow mode. Ten campaigns were carried out for six months in order to determine the e ciency of the methane oxidation in each column. Soil temperature, moisture and nutrients content in both lter beds were also determined. The oxidation global e ciencies were higher in the enriched column throughout all campaigns, with »71 and »95% for the control and enriched columns, respectively, demonstrating that this technology can be applied even in land lls where there is no energy recovery from biogas (as in most land lls in developing countries). Our study demonstrated that the use of substrates with high organic matter content and low cost in land ll cover layers might present high e cacy in the reduction of methane fugitive emissions. Even operating in eld-scale conditions, the results of this study were comparable to those obtained with bio lters on lab-scale (under controlled operational conditions).
