“…The SOAV values found in this study and the related ORE are reasonably comparable with those found by Jung et al (2019) [19]; in fact, the overall average complex odor removal efficiency was 97%. The average SOAV of the biowindow inlet gas was 15,805 uo E /m 3 , with a range of 6393-27,128 uo E /m 3 .…”

“…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].

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.

“…The genus Acinetobacter increased its abundance in the highest methane production and decreased in the final stage (Figure 4). Acinetobacter was the most abundant known sulfur-metabolizing genus and is also found in the consortium of sulfur-degrading bacteria (Jung et al 2019). The Chloroflexi phylum has filamentous morphology that may indicate its potential importance in maintaining the flake structure of anaerobic sludge is responsible for the production of acetate acid (De Vrieze et al 2014) and Kosmotoga belongs to the phylum Thermotogae, which degrades methanol into CO 2 and H 2 in syntrophic association with species of the family Methanobacteriaceae (Amin et al 2020).…”

The vinasse is a residue of ethanol production with the potential for methane production, requiring an allochthonous inoculum. Several microorganisms act in the different phases of anaerobic digestion, and the identification of these microbial communities is essential to optimize the process. The characterization of the microbiota involved in the biodigestion of vinasse was observed in the initial stage (IS), at the peak of methane production (MS) and the end of the process (FS) of the best performance assay by high-throughput sequencing. The highest methane production was 0.78 mmolCH4.gVS.h−1 at 243.7 h in the substrate/inoculum ratio of 1.7, with consumption partial of acetic, propionic and isobutyric acids and an 82% reduction of COD. High microbial diversity was found. The genus Clostridium, Acinetobacter, Candidatus Cloacamonas, Bacteroides, Syntrophomonas, Kosmotoga, the family Porphyromonadaceae and the class Bacteroidia were the most abundant in the maximum methane production. Methane production was driven by Methanobacterium and Methanosaeta, suggesting the metabolic pathways using were hydrogenotrophic and acetoclastic.
