Dimensionamento de um aterro sanitário de pequeno porte para a cidade de Martinópole-Ceará

Abstract

In recent years, the appeal of society towards sustainability and the preservation of the environment has been growing. The sanitary landfill has proved to be an excellent way for the final disposal of urban solid waste (USW). Within this technique, there is a wide variety of mechanisms that can be applied in order to isolate the waste and its decomposed from the environment, in order to preserve it and avoid a series of environmental impacts. The present work had as objective to exhibit some techniques of dimensioning of sanitary landfills. As a methodology, data referring to a small city in the state of Ceará were selected, to dimension the most important components of a USW landfill. With population and waste generation data, it was possible to obtain the total weight of waste to be sent to the small sanitary landfill throughout its useful life, which together with climatological data, geotechnical data, among others, allowed the elaboration of the dimensioning of landfill components, such as: the trench, the waterproofing system, the leachate drainage system, the surface runoff drainage system, the gas drainage system and the surface protection layers. The results presented here will serve as a basis for future works and will help in the design of engineering practices for urban solid waste landfills.
