Currently, depositing municipal waste in landfills is the dominating method in Lithuania. A large amount of landfill leachate is the main environmental problem. Municipal waste landfill leachate is characterized by high biochemical oxygen demand (BOD) containing a number of heavy metals and concentration of organic compounds. The colmatation of landfill leachate collection systems is another burning problem that occurs due to certain characteristics of leachate such as suspended solids, an increase in calcium and magnesium concentrations and vital activity of microorganisms. Therefore, it is necessary to examine conditions affecting these parameters. The paper presents and analyses the characteristics of experimental data, assesses the factors having the greatest influence on recent development and introduces the measures that should be taken into account so that to the ensure optimal operation of the systems for collecting municipal waste landfill leachate. Article in Lithuanian. Santrauka Pagrindinis atliekų tvarkymo būdas Lietuvoje yra jų deponavimas sąvartynuose. Viena iš svarbiausių aplinkosauginių problemų – dideli susidarantys sąvartyno filtrato kiekiai. Komunalinių atliekų sąvartynų filtratui būdinga didelis biocheminio deguonies suvartojimas (BDS), filtrate taip pat nemažà sunkiųjų metalų bei organinių junginių koncentracija. Svarbu išskirti ir tokią problemą kaip sąvartyno filtrato surinkimo sistemų kolmatacija, pasireiškianti dėl tam tikrų filtrato savybių: skendinčiųjų medžiagų, kalcio ir magnio koncentracijų padidėjimo ir mikroorganizmų gyvybinės veiklos. Būtina įvertinti sąlygas, turinčias įtakos šių parametrų kitimui. Pateikti minėtų savybių eksperimentinių tyrimų duomenys ir analizė. Įvertinta, kokie veiksniai turi didžiausią įtaką filtrato parametrų kitimui, pavyzdžiui, tai, jog bendrasis kietumas (kalcis ir magnis) lemia pH didėjimą, t. y. terpės šarmėjimą. Be to, išanalizuota, kokių priemonių reikėtų imtis optimaliam komunalinių atliekų sąvartyno filtrato surinkimo sistemų veikimui užtikrinti.

Landfills have been identified as one of the major sources of greenhouse gas (GHG) emissions and as a contributor to climate change. Landfill facilities exhibit considerable spatial and temporal variability of both methane (CH4) and carbon dioxide (CO2) rates. The present work aimed to evaluate the spatial distribution of CH4 and CO2 and their δ13C isotopic composition originating from a municipal landfill site, to identify its contribution to the local GHG budget and the potential impact on the air quality of the immediate surroundings in a short-term response to environmental conditions. The objective was met by performing direct measurements of atmospheric CO2 and CH4 at the selected monitoring points on the surface and applying a binary mixing model for the determination of carbon isotopic ratios in the vicinity of the municipal waste landfill site. Air samples were collected and analysed for isotopic composition using flask sampling with a Picarro G2201-I Cavity Ring-Down Spectroscopy (CRDS) technique. Kriging and Inverse distance weighting (IDW) methods were used to evaluate the values at unsampled locations and to map the excess of GHGs emitted from the landfill surface. The large off-site dispersion of methane from the landfill site at a 500 m distance was identified during field measurements using isotopic data. The mean δ13C of the landfill biogas emitted to the surrounded atmosphere was −53.9 ± 2.2‰, which corresponded well to the microbial degradation processes during acetate fermentation in the waste deposits. The calculated isotopic compositions of CO2 (δ13C = −18.64 ± 1.75‰) indicate the domination of biogenic carbon reduction by vegetation surrounding the landfill. Finally, amounts of methane escaping into the air can be limited by the appropriate landfill management practices (faster covers active quarter through separation layer), and CH4 reduction can be achieved by sealing the cover on the leachate tank.
