Investigação das técnicas de impermeabilização de aterros utilizadas no estado do Paraná

Abstract

Landfills can become a major problem for the environment, with contamination of surface water and groundwater, and for public health, with the spread of disease. These problems are often associated with poor management and poor execution. One of the steps in the implementation of landfills which, if carried out in an inadequate manner, will cause serious damage, both environmental and population, is waterproofing. When considering the problem of solid waste management in developing countries and, together with environmental preservation, this work studies possible solutions regarding the sealing of landfills and the damages caused by the inadequate execution of it. In addition to the bibliographical research, technical visits were carried out in sanitary landfills in Paraná, for the qualitative evaluation of the projects through interviews. In this way, landfill 2 was considered more appropriate. In sanitary landfill 1, some inadequacies were found related to the absence of the Municipal Solid Waste Plan, damaged fences, lack of a rainwater drainage system and the occurrence of residues discovered outside the service front. Landfill 3, which is still considered a Controlled Landfill, also has damaged fences and debris discovered outside the service front, in addition to the presence of waste pickers and the absence of a gas drainage system as negative points.
