What Does dump Mean
It is called landfill to the space in which they can pour things . This verb (pour), meanwhile, refers to spilling a liquid or throwing some kind of element . For example: “They found an unexploded grenade in a São Paulo landfill” , “The environmental organization recommended sealing the landfill” , “The dam's landfill is about to overflow” .
The most common use of the landfill is linked to the final deposit of the garbage ; that is why landfills are also known as garbage dumps or dumps. There are landfills authorized by governments , which choose the deposit site according to environmental, social and economic issues and then control its operation. Others, on the other hand, are clandestine dumps that arise spontaneously.
It is important to note that landfills, whether controlled or clandestine, always generate pollution . When waste decomposes, toxic gases can be released into the atmosphere. Decomposition can also affect groundwater, which is often consumed by residents of the area.
In addition to the names mentioned above, landfills are also known as landfills or landfills, and we can classify them in different ways. Broadly speaking, we must distinguish between the following two types:
* clandestine : it is a place in which a group of people decide to dispose of their solid waste, without having taken into account the issues that they do to care for the environment . As can be deduced, a clandestine landfill is a serious source of contamination, which inevitably leads to epidemics and other social upheavals. They generally settle 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 controlled , and its impact on the environment depends on the effectiveness of the measures taken by the body responsible for its creation.
To minimize contamination, authorities must waterproof the surface of 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 , for its part, refers to a combustible gas that originates in nature or in certain devices as a result of 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 swamp gas , because in these spaces a biodegradation of plant residues takes place that can be perfectly compared to that mentioned in the previous paragraph.
A hydraulic spillway , on the other hand, is the structure that allows the passage of water in a dam . The purpose of these weirs is to ensure the structure of the dam and to ensure that the water level does not vary too much.
The joint use of hydraulic weirs and gates can make a watercourse remain navigable.
The latest novel by John Irving, an acclaimed American writer, " Avenue of 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 sorting the garbage and thus making a living. 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 in the world have and the consequences of economic neoliberalism in the pyramid of social classes.
