These values are presented in Table 9. Table 9: Economic analysis of the biogas energy use Investiment (U$) O&M (U$/year) Revenues (U$/year) NPV 2,208,332.09 260,522.14 427,844.10 -139,886.28 The energetic use of biogas from MSW failed to present satisfactory values. The revenues from the sale of energy generated over the lifetime of the project do not exeeced the capital investments and operational costs. It is revealed by a negative NPV values. © 2022 Global Journals 1 Year 2022 62 Global Journal of Science Frontier Research Volume XXII Issue ersion I VI ( H ) Energetic Potential of the Biogas from Urban Solid Waste Generated in the Jacareí Municipal Landfill, Brazil
