Management of urban solid waste in the city of Manaus-AM. Thermal characterization aimed at generating energy and ending landfills and open dumps

With a population of two million inhabitants, Manaus – AM has undergone considerable industrial development and consequent urban development, resulting in a significant increase in the need for urban energy and the control of waste generated. All urban solid waste (MSW) is currently landfilled, causing health problems for the population, contamination of soil, rivers and groundwater. This article proposes the use of incineration to recover energy from urban solid waste to produce electrical energy in the metropolitan region of Manaus -AM. Energy characterization tests were carried out on MSW collected from various neighborhoods in the city, such as: gravimetry, thermogravimetry (TGA), immediate analysis, elemental analysis and higher calorific value (PCS) tests. Finally, the lower calorific value (IPC) was determined. The high percentages of recyclable materials, above 50%, combined with PCI values, presenting values ​​between 15,000 and 19,000 kJ/kg on dry days, calorific value equivalent to fuels cataloged in the bibliography as Lignite, Kiln-dried firewood and Coconut shells (17,000 kJ/kg), Mineral coal, (15,000 KJ/Kg), showed promise in future decision-making for the treatment of MSW by incineration.
