TL;DR: In this paper, controlled field measurements of methane emissions at sites in Illinois and California (USA) using a closed chamber technique were conducted. But the results of these experiments were limited.

TL;DR: Although bioreactor landfills have many advantages associated with them, challenges remain, including the persistence of ammonia-nitrogen in the leachate, which is likely a parameter that will determine when landfill postclosure monitoring may end.
Abstract: Although bioreactor landfills have many advantages associated with them, challenges remain, including the persistence of ammonia-nitrogen in the leachate. It has been suggested that ammonia-nitrogen is one of the most significant long-term pollution problem in landfills and is likely a parameter that will determine when landfill postclosure monitoring may end. The fate of nitrogen in bioreactor landfills is not well understood. As more landfills transition operation to bioreactors, more attention must be paid to how operating the landfill as a bioreactor may affect the fate of nitrogen. Processes such as sorption, volatilization, nitrification, denitrification, anaerobic ammonium oxidation, and dissimilatory nitrate reduction may all occur.

TL;DR: In this article, the average total nonmethane organic compound (NMOC) value for the Fresh Kills landfill was 438 ppmv (as hexane) versus the regulatory default value of 4000 ppmv( as hexane). Over 70 individual volatile organic compounds (VOCs) were detected and quantified in the landfill gas samples.
Abstract: The most common disposal method in the United States for municipal solid waste (MSW) is burial in landfills. Until recently, air emissions from these landfills were not regulated. Under the New Source Performance Standards and Emission Guidelines for MSW landfills, MSW operators are required to determine the nonmethane organic gas generation rate of their landfill through modeling and/or measurements. This paper summarizes speciated nonmethane organic compound (NMOC) measurement data collected during an intensive, short-term field program. Over 250 separate landfill gas samples were collected from emission sources at the Fresh Kills landfill in New York City and analyzed for approximately 150 different analytes. The average total NMOC value for the landfill was 438 ppmv (as hexane) versus the regulatory default value of 4000 ppmv (as hexane). Over 70 individual volatile organic compounds (VOCs) were detected and quantified in the landfill gas samples. The typical gas composition for this landfill was dete...

TL;DR: The analysis of data confirms that leachates from both landfills are severely contaminated with organics, salts and heavy metals, however, the organic strength of the leachate collected from the old landfill was reduced due to waste decomposition and continuous gas flaring.

TL;DR: In this article, the authors focused on achievements on landfill leachate treatment by different technology, which contains biological treatment and membrane technology, and predicted the development and prospect of landfill leACHate treatment were predicted.
