Comparative assessment of biogas emissions and the chemical composition of filtration waters at damps/landfills of solid municipal waste in the Arctic zone and the regions of central Russia

The authors present the results of a comparative assessment of biogas emissions and chemical composition of filtration waters at facilities of accumulated environmental harm — dumps/landfills of solid municipal waste located in the Arctic and non-Arctic regions of Russia. The analysis shows that biogas emissions at the Arctic sites are approximately 19—23.5 times lower than at sites in constituent entities of the Russian Federation not part of the Arctic zone of the Russian Federation. Sites of accumulated harm in terms of chemical composition of filtration waters and biogas emissions, depending on the stage of biochemical destruction of waste, are in the 4th—5th stages of biodegradation and destruction of waste (phases of stable methanogenesis and assimilation). The authors suggest executive authorities of the constituent entities of the Russian Federation, as well as design organizations to use the research results in the development of measures and technical solutions for the elimination of decommissioned dumps/landfills of solid municipal waste.
