Abstract
Aim. Investigation of the possibility of using modeling of the processes of the impact of the “landfill MSW – environment” system on the air environment to assess and develop solutions to minimize such impacts.
Methodology. The research uses: a systematic approach to modeling the processes of interaction of waste disposal facilities with the environment, calculation and modeling of gas emission processes based on: the values of the specific yield of biogas during the period of its active stabilized generation during methane fermentation and the period of complete fermentation of the organic part of the waste, taking into account the temperature conditions of the area of the object location; annual data on the amount of accumulated waste at the facilities; values of wind speed and direction, the degree of vertical stability of the atmosphere according to the average long-term data of observations of weather stations closest to the objects.
Results. The method of informational, including retrospective, modeling makes it possible to analyze the volumes and dynamics of gas-emission processes of different-age municipal solid waste disposal facilities, to assess and predict their environmental impact.
Research implications. The method of modeling gas emission processes in the MSW landfill – environment system is recommended to optimize eco-safe control of the system at all stages of its life cycle, as well as in case of waste burning.
