EVALUATION OF SOME GREENHOUSE GASES EMISSIONS FROM LANDFILL MODELS OF MUNICIPAL SOLID WASTE

Major greenhouse gases emissions (GHGs) that cause diseases and global warming evaporate from waste disposal in landfills. For this reason waste management skills in landfills have to be revised, otherwise the magnitude of ozone layer will decrease even more and the global warming consequences will get more obviously on the environmental scale. The resent situation on waste disposal and GHGs from European Union landfills were analyzed in this article. According to survey made in one Lithuanian landfill, the average amount of municipal biodegradable waste is 58%. The research study describes current GHGs emissions quantitative analysis from five laboratory scale municipal solid waste landfill models with different conditions. Conditions in all columns were differed by changing the inlet and outlet flows of air, water/leachate, and probiotics. The object of research is the accumulation of hydrogen sulfide (H2S) and oxygen (O2) from municipal solid waste landfill models. After analysis and assessment of emitted GHG’s from the municipal solid waste landfill models, the landfill model with the lowest emissions was identified. Suitable landfill model’s condition parameters helps to reduce greenhouse gas emissions and shorten landfill aftercare period.
