In this work, version 12 of the tool available on the EPA website was used. The metric for emissions results is relative to the measurement of one ton of CO 2 equivalent (MTCO 2eq ). Based on the waste characterization presented in Table 2 it was possible to develop different scenarios to different solid waste management practises. The mass of waste used will be the estimated production in 2040 acording to population projection and waste generation presented in Fig. 6. As 2.17% of the waste is recycled, the baseline scenario (Fig. 7) will consider this part of recyclables and the landfill of organic waste and of the tailings. It will be analyzed 3 scenarios according to Fig. 8; Fig. 9 and Fig. 10. Table 2:
