Análise comparativa do índice de qualidade de resíduos em municípios do extremo Sul do Piauí

Abstract

The growing generation of solid waste has become a global challenge, with significant impacts on the environment and public health. The study addresses the analysis of the final disposal areas of solid waste in three municipalities in the extreme south of piaui: corrente, monte alegre and riacho frio. The selection of these areas considered the number of inhabitants and logistical issues. Using the methodology of cetesb of the year 2022, site visits were conducted and applied a standardized form to collect information for the calculation of the waste quality index (iqr), divided into 41 parameters. The results revealed inadequate conditions in these areas, indicating that they can be classified as open dumps. In response to this finding, measures are proposed for the implementation of landfills, as required by law, such as law 12,305 of 2010, which determined the end of dumps. In addition, it emphasizes the importance of adequate funding of waste management to invest in sustainable technologies, such as recycling and energy use, to reduce the amount of waste sent to landfills and minimize environmental impacts. It is also suggested alternatives for the final disposal of solid waste in small and medium-sized municipalities, such as the creation of waste centers riados and formation of tescios between municipalities. In addition, it highlights the need for environmental education programs to raise awareness of the population about the importance of proper waste management
