Περίληψη

Landfilling is one of the most common ways of municipal solid waste (MSW) disposal indeveloping countries. Air pollutants emitted from landfills contributes to the emission in theatmosphere of greenhouse gases and cause serious problems to the human health. Methaneemission from landfill is serious environmental global concern as it accounts for approximately15 percentages of current greenhouse gas emissions. The current study was focused on thedetermination of air emissions from the Akrotiri landfill site which is located at the Akrotiri area(Chania, Greece). The models used are the triangular model, the stoichiometric model andLandGEM model. These models are used to estimate the total landfill gas production from agiven amount of waste. The models differ on their scientific approach for the quantification onemissions, their complexity and input data requirements. The LandGEM model was selectedfor the determination of more representative assessed landfill gas emission rates. Themaximum biogas production rate by the LandGEM model was calculated to be 1.64× 103 Mgyr-1 and was observed during the year 2008 for the A phase of the landfill, while for the Bphase the maximum biogas production rate was 2.70 × 103 Mg yr-1 and was observed during2014.
