“…As it was shown in a previous study, Methylocystis parvus appeared to be the dominant CH 4 -degrading bacteria in a biofi lter used to treat CH 4 [21]. This bacteria is mesophilic with an optimal range of temperature for growth between 23-25°C and 31-34°C [33].…”

Landfi ll gas emissions contribute to the greenhouse effect due to the presence of methane (CH 4 ). CH 4 emissions from old and small landfi lls can be reduced by using biofi ltration. The objective of this study was to optimize parameters that control CH 4 removal in a biofi lter. Temperature is one of the important parameters as well as the amount of nutrient solution (NS) supplied. The effects of the carbon dioxide (CO 2 ) concentration on CH 4 biofi ltration were also studied. Four biofi lters using an inorganic fi lter bed were studied under similar conditions: an inlet CH 4 concentration of 7000 ppmv and an air fl ow rate of 0.25 m 3 /h. A NS was supplied daily. The temperature was varied from 4°C to 43°C. The highest performance was obtained in the range of 31-34°C with an elimination capacity (EC) of 30 g CH 4 /m 3 /h for an inlet load (IL) of 80 g CH 4 /m 3 /h. The effect of the amount of NS supplied to the biofi lter at ambient temperature was also analyzed. The EC was 23 g CH 4 /m 3 /h for both 101 L NS /m 3 V bed /d and 34 L NS /m 3 V bed /d, but it fell to 17 g CH 4 /m 3 /h at 17 L NS /m 3 V bed /d. CO 2 concentrations were varied from 650 to 18,500 ppmv and no effect was noticed on the EC which remained constant at 18 g CH 4 /m 3 /h for an inlet load of 72 g CH 4 /m 3 /h.

“…In fact, some fi lter beds already contain the necessary macro and micronutrients to maintain an adequate microbial population [20]. However, an extra-addition of NS is needed in certain cases, particularly for inorganic fi lter bed [21].…”

“…Most cultured methanotrophs have whole-cell half saturation constants (K s ) for methane of ~1-10 µM (750 -7500 ppmv assuming equilibrium between aqueous and gas phases at 30°C), and thus, the atmospheric methane concentration, 1.7 ppmv, results in negligible methane consumption rates. This is one of the reasons why past approaches for atmospheric methane removal have focused mainly on source reduction where methane is in very high concentrations ( >7000 ppm) (Melse and Van der Werf, 2005;Nikiema et al, 2005). Here, we evaluated the feasibility of using biofiltration systems to accommodate methanotrophic activity to remove methane from lower concentrations of methane (i.e., < 6000 ppm).…”

“…Many of these devices have been successful in suppressing further increases in atmospheric methane concentration, but significant amounts of methane are still being emitted (IPCC, 2007). In response, recent research has considered methods to not only reduce methane emissions (Melse and van der Werf, 2005;Nikiema et al, 2005), but also to remove methane already in the atmosphere.…”

The overall objective of this project, "Strategies to Optimize Microbially-Mediated Mitigation of Greenhouse Gas Emissions from Landfill Cover Soils" was to develop effective, efficient, and economic methodologies by which microbial production of nitrous oxide can be minimized while also maximizing microbial consumption of methane in landfill cover soils. A combination of laboratory and field site experiments found that the addition of nitrogen and phenylacetylene stimulated in situ methane oxidation while minimizing nitrous oxide production. Molecular analyses also indicated that methane-oxidizing bacteria may play a significant role in not only removing methane, but in nitrous oxide production as well, although the contribution of ammonia-oxidizing archaea to nitrous oxide production can not be excluded at this time. Future efforts to control both methane and nitrous oxide emissions from landfills as well as from other environments (e.g., agricultural soils) should consider these issues. Finally, a methanotrophic biofiltration system was designed and modeled for the promotion of methanotrophic activity in local methane "hotspots" such as landfills. Model results as well as economic analyses of these biofilters indicate that the use of methanotrophic biofilters for controlling methane emissions is technically feasible, and provided either the costs of biofilter construction and operation are reduced or the value of CO 2 credits is increased, can also be economically attractive. 3 TABLE OF CONTENTSABSTRACT 2 EXECUTIVE SUMMARY 6

Composting is a proven technology for releasing the economic value of kitchen wastes. Following our previous efforts to expand and modify a novel, pilot-scale two-stage oxidative-reductive treatment technology for future implementation as a full-scale tower system, the objective of this work was to examine this scrubber tower system using the optimal operational scenario observed in our previous bench-scale experiments and with two different scrubbing liquid flow rates to allow for its subsequent application at full-scale. As the pH values ranged from 4.0 to 6.0 and from 10.0 to 11.5 in the acidic and alkaline scrubbers, respectively, and the total chlorine concentration ranged from 10 to 95 mg/L as Cl in the acidic scrubber, odor control treatment efficiencies of more than 95% were observed using this treatment technology. A slightly enhanced performance was obtained when a lower scrubbing liquid flow rate being employed, possibly due to the additional contact time between the scrubbing liquids and odor-causing substances in the composting gases. Although a higher scrubbing liquid flow rate increased the possibility of leaking chlorine into the treated gases, which affected the performance of this technology, stronger pH variation and chlorine consumption at the lower scrubbing liquid flow rate indicated the importance of controlling sufficient levels of scrubbing liquid in the system to maintain the treatment efficiency. The results provided insights regarding the use of this treatment technology for minimizing the adverse impacts associated with kitchen waste composting, including the emission of substances that may cause health and/or environmental concerns.
