A landfill is a place for the disposal of waste or garbage in which intends to take multiple measures to reduce the problems caused by other methods of treatment such as garbage dumps, these measures are, for example, the meticulous study environmental, economic and social from planning and site selection to site survey and monitoring throughout the life of the landfill impact.
To build a landfill is important to select the field that provides adequate technical conditions such as, topography, level found groundwater and availability of material to cover garbage.
In a landfill, as will placing trash, it is packed with equipment and covered with a layer of soil and other materials to subsequently covered with a layer of soil that is around 40 cm thick and this deposit another layer garbage and so on until the landfill is given by saturated.
It is an engineering method for the disposal of solid waste in the ground so that environmental protection is given by the spread of waste in thin layers, compacting the lowest practical volume and covering them with soil at the end of workday preventing adverse effects on the environment.
In addition, as a way to minimize environmental impact and how implementation of the Kyoto Protocol include landfill leachate treatments, which are produced by liquid waste, burning of decomposition gases, mainly methane, plantes reforestation area landfill and odor control. Because confined untreated waste containing a high potential danger to the environment (damage to the waterproofing in the course of time), in Europe already have rules requiring treatment of waste before proceeding to remove the potential danger both to the environment and human health.
