Abstract
The controversy involving the final disposal of municipal solid waste in the big cities exists for several years. The recent disaster involving a slurry leak from a regulated landfill in Rio de Janeiro called the attention for an important issue, “What if landfills are not the best alternative for waste treatment?” The environmental and social risks and the shortage of available areas to build landfills increase the demand for new processes to dispose urban waste. Waste-to-Energy facilities that treat the waste thermally and generate electricity and/or steam, close to the consuming centers, meet the search criteria for renewable sources of energy production. Doubly advantageous, they are presented as a solution to both the waste disposal problem and the growing energy demand in the cities. This technology is almost non-existent in Brazil, which opens the way for the research of better alternatives for thermal systems applied to the Brazilian waste. This work presents a sensitivity analysis of a thermo-economic study proposing a waste-to-energy facility to receive the urban waste of Rio de Janeiro (Brazil). Three scenarios were assessed and the energy production costs were estimated and compared with other power generating facilities of different sources (wind, hydroelectric, biomass, etc.). The conclusion shows that the energy produced in the proposed facility, combining waste and natural gas, is competitive with fossil and renewable energy power plants.
