This paper refers to a Municipal Solid Waste (MSW) compressibility study of waste disposed of in small scale sanitary landfills in the municipality of Presidente Lucena in the State of Rio Grande do Sul, Brazil. The research aims at the application and development of settlement prediction models based on settlement data collected on site. The studies we...

Settlement evaluation in sanitary landfills is a complex process, due to the waste heterogeneity, time-varying properties and influencing factors and mechanisms, such as mechanical compression due to the load application and creep, and physical-chemical and biological processes caused by the wastes decomposition. Many empirical models of analysis and lo...

The use of soil-bentonite mixtures for sanitary landfill liners with the purpose of retaining pollutants is becoming very common. This work shows the results of hydraulic conductivity and shear strength tests performed with soil-bentonite mixtures with bentonite contents of 3%, 5% and 7%. Additionally, shear strength test results carried out with a mixt...

The article consists of the application of a new rating methodology for final disposal of urban solid waste (USW) by evaluating the conformity of geotechnical and environmental aspects during the implementation and operating processes. The IQS was proposed when introducing the concepts of Environmental Management, in accordance with ISO 14001, to the La...
