SANITARY LAND
A sanitary landfill is a waste disposal site or waste site where multiple measures are planned to reduce the problems caused by other treatment methods such as landfills, such as meticulous environmental, economic and social planning and Site selection for site survey and monitoring throughout the life of the landfill impact.
To build a landfill it is important to select the field that provides adequate technical conditions, such as topography, groundwater level and availability of material to cover the garbage.
In a landfill, as well as the placement of garbage, it is packed with equipment and covered with a layer of soil and other materials for later covered with a layer of soil that is about 40 cm thick and deposits another litter of layer and so on until the landfill is given by saturated.
It is an Engineering method for the disposal of solid waste in the soil so that the environmental protection is given by the dispersion of waste in thin layers, compacting the smallest possible volume and covering them with soil at the end of the working day avoiding effects adverse effects on the environment.
In addition, as a way of minimizing the environmental impact and how the implementation of the Kyoto Protocol includes landfill leachate treatments, which are produced by liquid waste, burning of decomposition gases, mainly methane, landfill area for reforestation and odor control . Because untreated confined waste containing a high potential risk to the environment (damage to waterproofing over time), in Europe already have rules that require waste treatment before proceeding to eliminate the potential hazard to both the environment and human health .
