Emission and Neutralization of Methane from a Municipal Landfill-Parametric Analysis

Abstract

An attempt was made to estimate the annual production of CH4 at a municipal waste landfill site in Poland. As a matter of fact, the extent of the unorganized emission of CH4 from the landfill surface was approached based on the adopted mathematical model. The Ward agglomeration method for cluster analysis and the Pearson coefficient were employed to evaluate the distance-based similarity measure and to optimize methods for estimating methane emissions from a landfill as well as to verify the input parameters for the model. In order to calculate the content of biodegradable organic parts in the waste, morphological tests of the landfilled waste were performed. Physical quantities, measurements and the actual amount of the landfilled waste as well as the volume of CH4 neutralized in a collective flare were implemented in the model, respectively. The model-based findings and experimental outcome demonstrated stable gas production in the landfill with a high CH4 content. On the other hand, a rather low efficiency of the landfill passive degassing installation indicated the necessity to design and develop its active counterpart with the prospective application of the generated biogas for energy production in a cogeneration system.

Physicochemical indicators of the influence of a lined municipal landfill on groundwater quality: a case study from Poland

“…The leakage could also cause negative impact on aquatic environments near the landfill, which can be affected by leachate, even from lined landfill facilities. The above-mentioned factors may also result from unintentional failures at the landfill (Ciuła et al 2020).…”

Modelling the Migration of Anthropogenic Pollution from Active Municipal Landfill in Groundwaters

“…As the input data for pollution migration models, the results of modeling pollution emissions into the air can be applied, based e.g. on the IPCC model, containing the parameterization of the landfill [45]. According to El Mansouri et al [46], the main limitation in the development and implementation of these models is the quantification of flow parameters and transport phenomena.…”

Impact of Compressed Natural Gas (CNG) Fuel Systems in Small Engine Wood Chippers on Exhaust Emissions and Fuel Consumption

“…The adaptation of IC engines to combustion of gaseous fuels may become a contemporary scientific trend as to the use of biogas [90][91][92]. Biogas obtained from the decomposition of, e.g., sewage [93], organic municipal waste [94,95], animal faeces [96], agricultural and food industry waste [97,98] and plant materials [96,97,99], can be used by plants processing these materials to propel their machinery and equipment [100,101]. Biogas is a mixture of gases characterized by a varied composition, but it can be purified to bio-methane and then meet the quality standards of natural gas [102].…”
