摘要: Abstract This study aimed to determine theoretically, the electrical optimum power of LFG using maximum net benefit (MNB) methodology, and taking into consideration economic, demographic, regional aspects Inter municipal Consortium Micro-region High Sapucai for Sanitary Landfill (CIMASAS, as acronym in Portuguese), that is located southern part State Minas Gerais, Brazil. To this end, prognosis a 20-year period household solid waste generation region was estimated quantified based on population data, order estimate production energy can be generated. From point, thermal plant (TPP) by determined. The results indicated landfill could produce more 66,293,282 m 3 CH 4 (with 997 kW 2036) twenty years there would no economic viability generate from LFG, because Net Present Value (NPV) not positive. smallest achieve minimum attractiveness rate (MAR) 15% should 3,700,000 inhabitants under conditions studied. Considering Brazilian National Electric Energy Agency (ANEEL) Resolutions, it 339,000 with an installed 440 kW. In addition, outcome CIMASAS case-study demonstrated applicability MNB methodology determination TPP power.
