The word residue (originating in Latin residŭum) describe the material that loses utility after having fulfilled its mission or served to perform a certain job. The concept is used as a synonym for garbage for referring to waste that he man has produced.
For example: “We ask tourists to collect their waste and not to dirty the beaches”, "The city no longer knows what to do with the tons of waste generated by its inhabitants", “The teacher taught me that it is very important to recycle waste to help the environment”, "The guard challenged me because I threw the waste on the ground".
A residue, says the theory, is any element that is considered as a waste to which it is necessary to eliminate . It is assumed, therefore, that the residue has no economic value. Although the waste is usually accumulated in landfills or buried so that the decomposition process is completed there without affecting the environment, in recent years the recycling , which consists of recovering the waste to transform them into an object with a new useful life. When an individual throws away a plastic bottle, said container can decompose and generate environmental pollution, or be recycled through a treatment that allows the material to be reused.
When talking about waste as a synonym for garbage, it is necessary to underline the fact that there are various classifications for that one. Thus, taking as a pillar what is the origin and origin of it we find the fact that the waste can be domiciliary, commercial, industrial, hospital or urban.
In the event that the aspect that is taken into account is the composition of the garbage, it can be categorized as:
Organic waste. They are those that are composed of wastes of biological origin.
Inorganic wastes, those that have no biological origin but industrial or artificial.
Dangerous residues. Chemical substances of corrosive type, acids or radioactive waste are some of the garbage that are included in this typology and that must be treated with special care as they can seriously endanger the health of citizens.
To this classification, a fourth type of waste should be added, which is what is called a mixture. As the name implies, it is characterized because it is the result of the combination of various kinds of garbage.
For the math , residue is a concept that identifies the remainder that is obtained after dividing to two figures of the set of the whole numbers . This is the digit that results from the difference between the dividend and the product of the divisors by the quotients. That is to say: Rest = Dividend - (Divider x Quotient).
If the dividing operation concludes with a remainder equivalent to zero, it is considered as a division exact . However, if the rest is nonzero, the division is inaccurate .
Also, to all of the above, we have to add the existence of an expression that uses the term we are analyzing. It is "power residue." With this concept, what is referred to is the set of powers, powers or matters that the autonomies of a country do not attribute to the central government or to the government of the relevant region.
