Carbon dioxide, methane and nitrous oxide are the major Greenhouse Gases (GHG’s), which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. Therefore, there is immense concern for its abatement or utilization from landfi...
Abatement of methane diffuse emissions by biotrickling filtration using polyurethane foam as carrier
Methane anthropogenic diffuse emissions (below 1 % vv) are important, with a significant contribution of the waste management sector (estimatedaround 21%). Since biological alternatives are especially promising for the treatment of a wide number of gaseous pollutants, a biotrickling filter packed with polyurethane foam was employed to study the abatement of methane (0.2 – 1 % vv) in air emissio...
Tropospheric ozone and black carbon (BC) contribute to both degraded air quality and global warming. We considered ~400 emission control measures to reduce these pollutants by using current technology and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deat...
While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...
In Europe agriculture is an important contributor to emissions of the acidifying compound ammonia (NH3) and the greenhouse gases nitrous oxide (N2O) and methane (CH4). Measures to reduce one of these gases may also have an impact on emissions of the others. This study investigates the effects of control options for NH3, N2O, and CH4 that are available for the European agriculture on the emissio...
Combining policies to remove carbon dioxide (CO2) from the atmosphere with policies to reduce emissions can potentially decrease CO2 concentrations to earlier levels. We model the optimal selection of a dynamic portfolio of abatement, research and development (R&D), and negative emission policies under an exogenous CO2 constraint and with stochastic technological change. We find that near-term ...
Methane abatement pathways in Pd/Rh three-way catalysts have been investigated three scales ranging from a vehicle application size catalyst, model gas reactor and the catalyst powder form. A special test rig was designed for investigation of catalysts, allowing sampling along at discrete spatial locations, which are subject to different feed compositions. Dependent on history chemical environm...
Soil amendments have been proposed as a means to speed the development of plant and soil processes that contribute to water quality, habitat, and biodiversity functions in restored wetlands. However, because natural wetlands often act as significant methane sources, it remains unknown if amendments will also stimulate emissions of this greenhouse gas from restored wetlands. In this study, we in...
