Estudo sobre pneus inservíveis coletados no município de Campo Mourão - PR para aproveitamento energético

Abstract

The reuse of scrap tires as an alternative fuel is one of the main forms of final disposal in Brazil. This study aimed to quantify the generation of scrap tires in the municipality of Campo Mourão - PR, between the years 2011 and 2024, and evaluate their energy use. To this end, information was collected on the quantity of waste tires removed from the collection point, the calorific value of the tire, the energy generated for each kg of waste tire in cement kilns, from the company responsible for receiving and storing this waste, as well as the company licensed for transportation and final disposal. The results demonstrated that, in the period analyzed, a total of 4,417.91 tons of waste tires were collected in the municipality, which were destined for co-processing in cement industries, with the years 2013, 2015 and 2023 being the ones that generated the most energy to power the kilns, and in 2013, 407 tons, powered the kiln for 81.4h. In 2015, 392.01 tons fed 78.4h and in 2023, 357.98 fed the ovens for 72h. It was also possible to verify that 145,791.03 kg of CO2 were no longer emitted during the period, due to co-processing. It is concluded that the study showed that, over the years, the municipality of Campo Mourão - PR has played a relevant role in the implementation of the co-processing technique, collaborating with the environmental policies of the State of Paraná and Brazil.
