Waste management in Serbia is based on its disposal. The negative impact of landfill gas (LFG) on the environment can be significantly reduced through its collection, adequate processing and further use as fuel for cogeneration of gas plants. Biomass energy that originates from municipal solid waste landfills is now used as an efficiently fuel from renewable energy sources.Biogas is produced by anaerobic treatment of the organic mass of municipal waste. Landfill gas generated as a result of anaerobic digestion of biomass in digesters of landfill plants is basically methane CH4 (50-55%), carbon dioxide CO2 (40 - 45%) and non-methane volatile compounds, nitrogen suboxide N2O and nitrogen oxides NOx.This paper presents a model and defined quantities and composition of landfill gas at the landfill "Kulagića Ada" in Kraljevo. Based on the measurements performed on 10 biothorns of the landfill, a satisfactory percentage of methane of 56% in the landfill gas was established, and thus the possibility of its use as fuel in cogeneration engines.Using the software package ,,Ukraine LFG mod. v1” in Excel environment we received an hourly biogas production of 205 m3/h as well as recommendations for the selection of the appropriate type and power of gas cogeneration engines.
