  • Kyoto mistakes

    The Kyoto Protocol conflicts with a rational view of what short-term climate policy should achieve. Chosen emission reduction targets conflict with individual and social interests, and will therefore be hard to reach. Possibilities to cheat on the agreement are plentiful. Methane emission reduction may help to meet the short-term aims, but does not contribute to the ultimate objective.Keywords: ...

  • Meeting Emission Control Through Improved Actuation

    Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren’t designed using the latest materials and technologies. New technologies can also help to ...

  • Renewable energy and sustainable development in Hungary

    This paper presents an overview of the use of renewable energy in Hungary. It analyses the role of renewables in the sustainable development of the country and in the reduction of greenhouse gas emissions. Although Hungary is rich in geothermal sources, the use of renewable energy sources is not economically viable in the country compared with traditional energy sources. In Hungary, only biomass ...

  • In-situ moisture content measurement of landfill cover using Time Domain Reflectometry

    The amount of methane that vent from landfills is dependent on the physical, chemical and biological components of the soil cover; moisture content and temperature of the soil being the major controlling factors. Previous studies have attempted to correlate moisture content and temperature with methane emission by collecting soil samples from landfill soil covers and analysing it in the ...

  • Climate Change Mitigation and Water

    Both natural and anthropogenic processes contribute significantly to climate change. Among the natural processes are changes in the energy emitted from the sun, the distance between the sun and the earth, and eruptions from volcanoes. The main anthropogenic processes include emissions of greenhouse gasses such as methane (CH4), nitrous oxide (N2O), and ...

  • Effect of methane generation potential and rate constant on the generation of methane from municipal solid waste landfill site: a case study

    The methane generation potential L o and methane generation rate constant k are the two important parameters which have been used for methane generation evaluation. An attempt has been made in the present research paper to evaluate the methane generation at Pirana landfill site of Ahmedabad by varying the values of methane generation potential L ...

  • Options to Reduce Methane Emissions

    This study analyses methane emissions in the EU and strategies to control them. It considers options for the reduction of emissions from each of the main source sectors, agriculture, waste, coal mining and the oil and gas industry, and assesses costs and applicability of the mitigation options available to produce cost curves for reducing emissions. The study also makes projections of methane ...

  • A preliminary study of the application of Background Oriented Schlieren (BOS) for the qualitative imaging of methane emissions from coal

    Methane presents a pervasive risk in most coal mines, its dilution being one of the primary objectives of the ventilation system. Although many different types of detectors and techniques exist for quantifying methane, little is known about the qualitative aspects of methane, such as visualising how this gas flows from coal. Background Oriented Schlieren (BOS) provides a potential method from ...

  • Greenhouse Gas Inventories and Wastewater Treatment Plants

    ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

  • Polish gas from Polish coal: environmental benefits

    The development of coalbed methane gas from Polish coal offers a significant opportunity to reduce noxious pollutant emissions associated with coal combustion. A review of energy supply and consumption within Poland, and of available coalbed methane resources, indicates that use of coalbed methane could eliminate 40-60 million tonnes of sulfur dioxide and particulates from the atmosphere, save ...

  • Mitigating methane emissions from passive landfill vents: a viable option for older closed landfills

    This study investigated the use of biofilters to reduce methane emissions from landfill passive gas vents. Two biofilter designs were evaluated. The two filter designs achieved similar percent oxidation averages. The radial biofilter design, however, obtained a much higher methane oxidation rate. The higher surface area of flow in the radial biofilters decreased the methane influx leading to ...

  • Utilisation of Municipal Solid Waste Compost as landfill cover soil for reducing greenhouse gas emission

    Municipal Solid Waste Compost (MSW-C) was introduced for improving landfill cover soil properties and enhancing methane oxidation. The landfill cover soil was irrigated with leachate for maintaining appropriate moisture content for methane oxidation reaction. It was found that MSW-C was an effective landfill cover material for landfill gas emission control exhibiting the highest Methane Oxidation ...

  • Understanding energy saving and CO2 reduction in wastewater treatment plants

    Wastewater Treatment Plants (WWTPs) have to deal with the issue of energy saving and/or CO2 reduction. Aeration, sludge return, chemical dosing, sludge reduction, sludge digestion, etc. could indeed have some function on this issue. On the other hand, controlled processes of COD and nutrient conversions could also be of benefit to the issue. With this paper, ...

  • Evaluation for the reduction and utilisation of coal mine methane emission with AHP method and decision tree

    We used the analytic hierarchy process (AHP) method to construct an evaluation index system for the reduction and utilisation of coal mine methane (CMM) emission. We used the system to evaluate some coal mines in China and other major coal–producing countries. To simplify the process of evaluation, we established an evaluation model based on the evaluation data and on a decision tree. We ...

  • Greenhouse gas emission potential of the municipal solid waste disposal sites in Thailand

    Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique ...

  • Actively aerated methanobiofilters to control methane emissions from landfills

    Methane (CH4) capture at sanitary landfills for energy recovery is capable of reducing the impact of CH4 on the global atmospheric carbon budget. However, gas capture may only be viable where gas quantities are high enough to warrant economical energy production. Considering the potential global warming impacts, there is a need to ...

  • Voluntary carbon standard offset project registration

    MJB&A is supporting a major natural gas transmission company with the registration of its U.S. carbon offset projects on its natural gas transmission system.  The company is implementing an advanced leak detection and repair project to reduce methane emissions from its natural gas pipeline compressor stations.  This project uses approved baseline methodology AM0023 of the Clean ...

  • The use of methanotrophic applications to control of fugitive methane emissions from the biodegradation of organic waste

    Large amounts of methane (CH4) escapes to the atmosphere through fugitive emissions arising from anthropogenic sources. This is detrimental because the Global Warming Potential (GWP) of CH4 is 25 times that of carbon dioxide (CO2) on a 100 year time horizon. As a result, there has been increasing ...
