Análise da área de disposição final de resíduos sólidos do município de Gilbués - PI

Abstract

The emergence of new technologies with the Industrial Revolution promoted the economic expansion, which with the practicality in industrial production also contributed to the generation of more jobs and a better quality of life for the people, thus causing the rural exodus of the population that lived in the countryside to the city. With the population growth proportionally, there is still an increase in the consumption of products and consequently the generation of Urban Solid Waste (RSU). In this way, in view of the environmental problems generated by the incorrect handling of solid waste, the present work has the objective of analyzing the final disposal area of solid wastes of the Municipality of Gilbués, Piauí. By means of on-site visits, he obtained the data for the calculation of the Land Quality Index (IQR), in which the methodology adopted by Companhia Ambiental do Estado de São Paulo -CETESB (1998) was used, since it is one of the most used and consists of the application of a standardized checklist subdivided in three steps: characteristics of the place, implanted infrastructure and operational conditions. In the item characteristics of the place it was notable that the area only complies with the norm established in NBR 13.896 ABNT, (1997) in relation to the distance of the water body with 250 m greater than the 200 m established by law, however it does not fit in relation to the proximity of population centers, since it presents a distance of 350 m, with a minimum of 2000 m, in relation to the access road, it has a distance of 15 m to 25 m, smaller than the established 200 m. In terms of infrastructure in the area, the sub-items did not score, and thus had an inefficiency with respect to the analyzed parameters. Regarding the Operating Conditions implemented in the place when observing the general aspects of the area, it was evaluated as inadequate, as it does not follow the characteristics that should exist. Regarding the final disposal area of Gilbués-PI MSW, the following scores were obtained in relation to the Characteristics of site 9, already in the Infrastructure Implementation the value was 0 and in Operating Conditions 3. With the results presented after the calculation of the IQR, the final area of the RS of Gilbués-PI is considered inadequate because it presented an extremely low value of 0.92, being considered as an open dump, presenting a flawed system and inefficient. Therefore, it is necessary to implement public policies aimed at minimizing this environmental degradation, adopting appropriate measures in the case the introduction of a landfill, which can meet the existing needs in accordance with current legislation regarding the proper management of waste produced in each municipality.
