It is called dump to the space in which you can pour things . This verb (pour), meanwhile, refers to spill a liquid or to throw some kind of element . For example: "They found an unexploded grenade in a San Pablo landfill", “The environmental organization recommended sealing the landfill”, "The weir of the dike is about to pass".
The most common landfill use is linked to final trash bin ; This is why landfills are also known as landfills or dumps. exist authorized landfills for the governments , who choose the deposit site according to environmental, social and economic issues and then control its operation. Others, however, are clandestine dumps that arise spontaneously.
It is important to note that landfills, whether controlled or clandestine, always generate contamination . When the waste decomposes, toxic gases can be released into the atmosphere. The decomposition can also affect the groundwater that is often consumed by the residents of the area.
In addition to the names mentioned above, landfills are also known as landfills or dumps, and we can classify them in different ways. In broad strokes, we must distinguish between the following two types:
* clandestine : This is a site where a group of people decide to dispose of their solid waste, without taking into account the issues that they care for. environment . As can be deduced, a clandestine landfill is a serious source of pollution, which inevitably results in epidemics and other social disorders. They are usually established in natural sinks or depressions;
* urban or municipal : It is the one that the municipal government chooses after having carefully studied the relevant social, environmental and economic aspects. This type of landfill is also called sanitary or checked, and his impact in the environment it depends on the effectiveness of the measures taken by the body responsible for its creation.
To minimize pollution, authorities must proof the surface from the landfill, ensuring that pollutants do not reach the natural soil and groundwater. On the other hand, it is important that the biogas generated by the decomposition of the garbage is recovered.
The concept of biogas , meanwhile, refers to a combustible gas that originates in nature or in certain devices as a result of the reactions that biodegrade organic matter. When oxygen is not present, that is, when we are in an anaerobic environment, microorganisms act in such a way that this phenomenon occurs.
Another name by which this compound is known is gas of the swamps, because in these spaces a biodegradation of plant residues takes place that can be perfectly compared with the one mentioned in the previous paragraph.
A hydraulic dump , on the other hand, it is the structure that allows the passage of water in a dam . The purpose of these landfills is to ensure the structure of the dam and make the water level not vary too much.
The joint use of hydraulic dumps and gates can make a course of water remain navigable.
The latest novel by John Irving, an acclaimed American writer, "Avenue of the mysteries", tells the story of two brothers, Juan Diego and Lupe, who are raised in a landfill. They are called" the garbage boys "because they are in charge of sort out trash and make a living like that. The descriptions of the environment in which these two children live are detailed and chilling and invite us to think about the miserable lives that many people have in the world and the consequences of economic neoliberalism in the pyramid of social classes.
