Management of urban solid waste in the city of Manaus-AM. Thermal characterization for power generation

Abstract

With a population of two million inhabitants, Manaus – AM has undergone a considered industrial development and consequent urban development, resulting in a significant increase in the need for urban energy and in the control of waste generated. All municipal solid waste (MSW) is currently deposited in landfills, causing health problems to the population, contamination of soils, rivers, and groundwater. This article proposes the use of incineration to recover energy from urban solid waste to produce electricity in the metropolitan region of Manaus - AM. Energy characterization tests were carried out on MSW collected from various neighborhoods of the city, such as: gravimetry, thermogravimetry (TGA), immediate analysis, elemental analysis and superior calorific value (PCS) tests. Finally, the lower calorific value (PCI) 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 the fuels cataloged in the bibliography such as lignite, kiln-dried firewood and coconut shells (17,000 kJ/kg), Coal, (15,000 KJ/Kg), showed promise in a future decision-making for the treatment of MSW by incineration.
