摘要

Climatic conditions such as high precipitation rates play an important role in the degradation of urban solid waste as well as influence the quantity and quality of the leachate generated.rnTaking into account the significant contamination potential of waste effluent, and considering that the understanding of waste behavior is of paramount importance in proper landfill site design, the behavior of urban solid waste is an issue that still requires up-to-date research.rnA large number of developing countries are situated in the southern hemisphere under the influence of tropical weather. In developing countries, the waste generated in some large cities is dumped in open areas, which lack the appropriate engineering infrastructure. This significantly increases the risks of contamination, affecting both the environment and the surrounding population.rnThis paper presents the results of a five year research program carried out at a solid waste landfill in Brasilia, Brazil. Field experimental cells and intermediate scale boxes were used to monitor the geotechnical, geochemical and biological behavior of urban solid waste. Variations in the internal waste temperatures, settlement rates, influence of oxygen diffusion through the waste, presence of aerobic and anaerobic bacteria, and variations in the quality and quantity of ieachate generated were studied.
