Transport mechanisms and emission of landfill gas through various cover soil configurations in an MSW landfill using a static flux chamber technique

The article analyzes the problem of negative impact of landfills for solid municipal waste disposal in the Moscow region. The dynamics of growth of the rate of accumulation of solid municipal waste is considered. The data on the largest operating MSW landfill in the Moscow region were studied. A scheme of geoecological impact and release of landfill gas into the environment has been drawn up. The standards of payment and conversion factors for emissions of pollutants into the air from landfills are given. The types of pollution at the landfills of MSW, as well as ways of negative impact leading to contamination of all components of the environment, were identified.

Solid Waste Landfills

The problems of landfill gas collection and treatment at municipal solid waste landfills are considered. The analysis of the main methods of landfill gas treatment and use is carried out. The characteristic of the gas collection system used at the Kuchino MSW landfill is presented. Installation of a landfill gas treatment system on a flare at the stage of landfill closing will reduce methane emissions by 65 % in comparison with a landfill not equipped with such a system, and the fee for negative impact on environmental objects will decrease by 30 %. Based on the analysis of monitoring studies of landfill biogas emissions from the Kuchino MSW landfill, a decrease in the concentration of pollutants in the landfill gas after its treatment to the MPC level and below was established.

Short Time

A laboratory investigation, supplemented with a theoretical analysis, was conducted to determine the errors associated with the closed flux chamber technique commonly used to determine the surficial gas emissions from landfills. The results indicate that the errors largely depend on the chamber dimensions, including chamber height, surface gas flux rate, and time interval over which the data are collected. Selection of a proper chamber height for a particular flux rate and the use of a short time period for measurement reduce the errors significantly.Key words: landfills, closed flux chambers, surface emission, laboratory investigation, errors.

Ongoing Experiment

While a significant amount of work has been conducted to assess the concentration of pollutants in soils and waterways near land that has been amended with biosolids, a relatively small body of research investigating emissions to atmosphere is available in the literature. Some studies have indicated that while the CO2emissions from soils decrease with fertiliser application, the CH4and N2O emissions might be increased, offsetting the benefit. The objective of the research presented in this paper was to address this gap, by the use of a flux chamber technique to measure soil-atmosphere gas exchanges from the application of biosolids to land. This was done by applying three different types of biosolids to soils and measuring gases at the soil-atmosphere interface. The measurements were taken on areas with three different types of vegetation. The gases were collected using a flux chamber technique and analysed by gas chromatography. The results presented here are preliminary findings of an ongoing experiment. Insignificant variation appeared to occur between different areas of vegetation; however, small variations in gas concentrations were observed indicating a need for continued monitoring of soil-atmosphere gas exchanges to determine the long-term impacts on the atmosphere and the environment.
