AB - Waste management in the Republic of Serbia is based on landfilling. As a  result of such year-long practice, a huge number of municipal waste landfills  has been created where landfill gas has been generated. Landfill gas, which  is essentially methane (50-55%) and carbon dioxide (40-45%) (both GHGs), has  a great environmental impact which can be reduced by using landfill gas in  cogeneration plants to produce energy. The aim of this paper is to determine  economic and environmental benefits from such energy production. For that  purpose, the database of cogeneration potentials (CP) of 51 landfills in the  Republic of Serbia (RS) was created. Amount of landfill gas generated at each  municipal landfill was calculated by applying a first order decay equation  which requires the data about solid waste production and composition and  about some landfill characteristics. For all landfills, which have over  100,000 m3 each, a techno-economic analysis about building a CHP plant was  conducted. The results have shown, that the total investment in 14 CHP plants  with payback period of less than 7 years amounts € 11,721,288. The total  nominal power of these plants is 7 MW of electrical power and 7.9 MW of  thermal power, and an average payback period is about 61 months. In addition,  using landfill biogas as energy source in proposed plants would reduce  methane emission for 161,000 tons of CO2 equivalent per year. [Projekat  Ministarstva nauke Republike Srbije, br.
