Análise do gerenciamento de resíduos sólidos urbanos na cidade de Timbaúba - PE: estudo de caso.

Abstract

The development of Brazilian cities has not kept up with population growth, and several problems related to the lack of management and management of Urban Solid Waste (USW) have been observed. Therefore, the search for solutions to the problems caused by the generation, collection, lack of treatment and inadequate final disposal of solid waste has been one of the main socio-environmental challenges of today. In this context, the present study aimed to analyze the services of collection, transportation and final disposal of MSW generated in the city of Timbaúba - PE. The methodological steps comprised the realization of the simplified environmental diagnosis of these management services, the calculation of the Index of Quality of Landfill Waste (IQR), the quantitative assessment of environmental impacts of negative and significant origin and the proposition of environmental control measures. These steps, in general, were developed from research in the scientific and technical literature, collection of secondary data, field visits and photographic records. According to the results obtained, the conventional collection of SUW generated in Timbaúba - PE presented a wide coverage, reaching a population attendance rate of 100%. The IQR of the SUW final disposal area was 1.6, indicating that the site has inadequate operating conditions. We identified 22 negative and significant environmental impacts related to the evaluated stages of SUW management. The impact index determined corresponded to - 4.65, demonstrating the negative action that the lack of proper management of MSW causes to the biotic, abiotic, and anthropic environments. In conclusion, this study will serve as a guiding document for governmental bodies to develop a SUW management plan in an integrated way in Timbaúba - PE.
