Download or read book Methane and Climate Change written by Dave Reay and published by Routledge. This book was released on 2010-08-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is a powerful greenhouse gas and is estimated to be responsible for approximately one-fifth of man-made global warming. Per kilogram, it is 25 times more powerful than carbon dioxide over a 100-year time horizon -- and global warming is likely to enhance methane release from a number of sources. Current natural and man-made sources include many where methane-producing micro-organisms can thrive in anaerobic conditions, particularly ruminant livestock, rice cultivation, landfill, wastewater, wetlands and marine sediments. This timely and authoritative book provides the only comprehensive and balanced overview of our current knowledge of sources of methane and how these might be controlled to limit future climate change. It describes how methane is derived from the anaerobic metabolism of micro-organisms, whether in wetlands or rice fields, manure, landfill or wastewater, or the digestive systems of cattle and other ruminant animals. It highlights how sources of methane might themselves be affected by climate change. It is shown how numerous point sources of methane have the potential to be more easily addressed than sources of carbon dioxide and therefore contribute significantly to climate change mitigation in the 21st century.

This book was released on 2018-08-25 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).

Available in PDF, EPUB and Kindle. Book excerpt: Methane is an important greenhouse gas that can cause global warming. The present concentrations of methane are nearly three times higher than several hundred years ago. Today, more than 60% of the atmospheric methane comes from human activities, including rice agriculture, coal mining, natural gas usage, biomass burning, and raising of cattle. Methane affects the stratospheric ozone layer and the oxidizing capacity of the atmosphere, which in turn control the concentrations of many man-made and natural gases in the atmosphere. This book brings together our knowledge of the trends and the causes behind the increased levels of methane. Based on the scientific information on the sources and sinks, and the role of methane in global warming, strategies to limit emissions can be designed as part of a program to control future global warming.

Available in PDF, EPUB and Kindle. Book excerpt: A reasonable case could be made that the scientific interest in catalytic oxidation was the basis for the recognition of the phenomenon of catalysis. Davy, in his attempt in 1817 to understand the science associated with the safety lamp he had invented a few years earlier, undertook a series of studies that led him to make the observation that a jet of gas, primarily methane, would cause a platinum wire to continue to glow even though the flame was extinguished and there was no visible flame. Dobereiner reported in 1823 the results of a similar investigation and observed that spongy platina would cause the ignition of a stream of hydrogen in air. Based on this observation Dobereiner invented the first lighter. His lighter employed hydrogen (generated from zinc and sulfuric acid) which passed over finely divided platinum and which ignited the gas. Thousands of these lighters were used over a number of years. Dobereiner refused to file a patent for his lighter, commenting that "I love science more than money." Davy thought the action of platinum was the result of heat while Dobereiner believed the ~ffect ~as a manifestation of electricity. Faraday became interested in the subject and published a paper on it in 1834; he concluded that the cause for this reaction was similar to other reactions.

This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice production is affected by changing climate conditions and has the dual role of contributing to global warming through emissions of the greenhouse gas methane. Climate change has been recognized as a major threat to the global environment. Because of insufficient field data, rice-growing countries face a problem when trying to comply with the United Nations Framework Convention on Climate Change stipulations to compile a national inventory of emissions and to explore mitigation options. Given the expected doubling in rice production in Asia, the need to evaluate the interaction between climate change and rice production is critical to forming a sound basis for future directions of technology developments by policy makers, agriculturists, environmentalists, rice producers, and rice consumers. The present book comprises two sections. The first part documents a comprehensive overview of the results achieved from an interregional research effort to quantify methane emission from major rice ecosystems and to identify efficient mitigation options. This research report broadens understanding of the contribution of rice cultivation to methane emissions and clarifies that emissions are relatively low, except in specific rice ecosystems, and that these high emissions could be ameliorated without sacrificing yield. The second section shows results from other projects that investigated the role of rice cultivators in field and laboratory approaches. The findings represent inputs for future modeling approaches in the role of rice cultivators. The expanded database generated by other projects is reflected in modeling efforts.

This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is a short-lived greenhouse gas that is released during the production and transport of coal, natural gas, and oil; the raising of livestock and other agricultural practices; and the decay of organic waste in municipal solid waste landfills and some wastewater treatment systems. Although it is short-lived, methane has more than 20 times the atmospheric warming effect of carbon dioxide. However, it is a primary component of natural gas, so efforts to reduce methane emissions can take advantage of technologies that capture and reuse the gas as a fuel, potentially bringing about cost-effective reductions in emissions. The Global Methane Initiative (GMI) is a voluntary international partnership that promotes methane recovery and reuse activities in developing and transition economies. Program partners and funders include national governments, private-sector firms, development banks, and nongovernmental organizations. As a founding member of the partnership, the U.S. government contributes funding and other types of support to GMI primarily through the U.S. Department of State (specifically, its Bureau of Oceans and International Environmental and Scientific Affairs and its Office of Global Change) and the U.S. Environmental Protection Agency. To help gauge the effects and value added of its support for the program, the Department of State requested an evaluation of GMI's activities and outcomes relative to its contributions in fiscal years 2006-2010. The evaluation employed a mixed-methods approach that combined quantitative and qualitative information to document program resources and activities and to illustrate program outcomes, including information from in-country site visits. The report also presents some recommendations for how data collection could be improved to answer more sophisticated questions in the future about the effectiveness of GMI and the value added by the department's contributions.

This book was released on 2018-06-20 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in-depth insights into the most recent developments in different areas of microbial methane and methanol utilization, including novel fundamental discoveries in genomics and physiology, innovative strategies for metabolic engineering and new synthetic approaches for generation of feedstocks, chemicals and fuels from methane, and finally economics and the implementation of industrial biocatalysis using methane consuming bacteria. Methane, as natural gas or biogas, penetrates every area of human activity, from households to large industries and is often promoted as the cleanest fuel. However, one should not forget that this bundle of energy, carbon, and hydrogen comes with an exceptionally large environmental footprint. To meet goals of long-term sustainability and human well-being, all areas of energy, chemicals, agriculture, waste-management industries must go beyond short-term economic considerations and target both large and small methane emissions. The search for new environment-friendly approaches for methane capture and valorization is an ongoing journey. While it is not yet apparent which innovation might represent the best solution, it is evident that methane biocatalysis is one of the most promising paths. Microbes are gatekeepers of fugitive methane in Nature. Methane-consuming microbes are typically small in number but exceptionally big in their impact on the natural carbon cycle. They control and often completely eliminate methane emission from a variety of biological and geothermal sources. The tremendous potential of these microbial systems, is only now being implemented in human-made systems. The book addresses professors, researchers and graduate students from both academia and industry working in microbial biotechnology, molecular biology and chemical engineering.

This book was released on 2025-07-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2023 shattered global climate records as the warmest year in the modern record, bringing with it devastating impacts on human and natural systems. Methane emissions, about 60% of which come from human activities, are a major contributor to global warming, second only to carbon dioxide (CO2). Methane is relatively short-lived in the atmosphere but is 80 times more potent than CO2 at trapping heat over a 20-year period. Together with reducing CO2 emissions, rapid and sustained reductions in methane emissions are critical to limit both near- and long-term warming in future decades. But given the many barriers to achieving needed emissions reductions at scale, researchers are exploring the potential of technologies to remove methane from the atmosphere. A Research Agenda Toward Atmospheric Methane Removal is the first report of a two-phase study to assess the need and potential for atmospheric methane removal. This report identifies priority research that should be addressed within 3-5 years so that a second-phase assessment could more robustly assess the technical, economic, and social viability of technologies to remove atmospheric methane at climate-relevant scales. The research agenda presented in this report includes foundational research that would help us better understand atmospheric methane removal while also filling knowledge gaps in related fields, and systems research that seek to address what developing and/or deploying atmospheric methane removal at scale would entail. A Research Agenda Toward Atmospheric Methane Removal also assesses five atmospheric methane removal technologies that would accelerate the conversion of methane to a less radiatively potent form or physically remove methane from the atmosphere and store it elsewhere.

Download or read book Co-conversion of Gaseous Carbon Dioxide and a High Strength Aqueous Organic Contaminant (phenol) to Methane Via a UASB Reactor written by Ana Argelis Ávila Moltó and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: More economical and efficient means are required to decrease or to recover greenhouse gases (GHG) exhausted into the environment, and to decrease the amount of wastewater that is degrading the water bodies worldwide. Therefore the objective of this research is to develop a system that will treat both carbon dioxide and a high strength wastewater; for this purpose an Up-flow Anaerobic Sludge Blanket (UASB) reactor was used. Previous studies showed that carbon dioxide could be converted to methane with organic acids. In this study, the addition of carbon dioxide will act as the co-substrate needed in order to treat higher concentrations of the toxic pollutant phenol in wastewater without any recirculation of the effluent. This is based on previous studies that showed that higher concentrations (1260 mg/L phenol) can be treated if a co-substrate is added. An anaerobic biomass used for this experiment was taken from two reactors treating sucrose and acetic acid. Then, it was acclimated by increasing stepwise the concentration of phenol, while reducing the concentration of sucrose and/or acetic acid. Methanogenic activity tests were performed to evaluate the toxicity limits of phenol toward the biomass. Two sets of two reactors were used. The first set contained the biomass acclimated with sucrose; the second set contained the biomass acclimated with acetic acid. Control reactors had phenol added as the carbon source; whereas in the other reactors, carbon dioxide was added as the co-substrate. The parameters monitored were chemical oxygen demand, volatile suspended solids, methane content of the biogas and production, phenol concentrations, alkalinity, and dissolved carbon dioxide. It was shown that both CO 2 and phenol could be degraded in an UASB reactor with reduction values that ranged from 86-88% and 86-94% respectively. Total COD reduction ranged from 92-97% and methane content in the biogas ranged from 64-70%. The biomass showed a steady organic content throughout the experiment after a sudden decrease during the acclimation period. Overall, the reactors with the best performances were R4 (acetic acid-fed biomass with CO 2) and R2 (sucrose-fed biomass with CO 2) although this last one showed some performance similarities with R3 (acetic acid-fed biomass without CO 2) and the reactor which was more prone to loading shock was R1. Carbon dioxide, a waste gas, poses a great advantage in the anaerobic process since it was proven to be a good co-substrate in the biodegradation of a high strength wastewater, with a higher methane recovery. Adding carbon dioxide to UASB reactors in order to boost degradation instead of releasing it to the environment is a good remediation proposal.
