A residue is a scrap produced by man or a material that is unusable after having done a job or accomplished his mission. Therefore, it is necessary to eliminate or recycle the waste so that they acquire a new possibility of use.

He danger , on the other hand, is the risk wave impending contingency Something bad happens. It is possible that the danger is a physical and real threat, or something abstract that the human being understands as potentially harmful.

A hazardous waste Therefore, it is a waste with intrinsic properties that put the Health of the people or that can cause damage to the environment. Some of these properties are as follows: inflammability , the toxicity , the corrosivity , the reactivity and the radioactivity .

Among the most common hazardous wastes are ore particles dragged by the Water and mixed with mud, which come from mines, spills of various substances in surface channels and emissions of toxic gases through chimneys and exhaust pipes.

It should be mentioned that historically, these wastes have not always been considered dangerous; on the contrary they were part of the common waste of various industrial fields and even of private homes. Since there was no regulation that indicated to citizens what to do with these materials, and that there was not enough information about the risks that irresponsible handling could entail, it was normal for them to be poured into bodies of water, such as rivers or the sea, or that they were left in common garbage dumps.

It was based on agreements in favor of environment such as the Rotterdam Convention or the Basel Convention that people began to become aware of this issue, and various countries, both developed and developing ones, undertook the task of legislating the handling of hazardous wastes, as well as their classification and the necessary measures to store them.

Hazardous wastes usually come from: hospitals (they are called biological); from the pharmaceutical industry and the chemical industry; forestry or agricultural activity, given the use of biocides, fungicides and pesticides; mines; the energy industry (certain types of oil); the oil industry (aqueous, bituminous and tar emulsions, among others); textile industry (dyes, oxidized chromium and acids); military industry; scientific research and development centers (reagents and solvents); plastics industry

One of the processes most common for the treatment of hazardous waste is known as inertization and it consists in minimizing the potential risk of the non-recoverable waste until its final disposal.

Yes one industry evade these rules and try to get rid of their hazardous waste in another way (throwing them into a river, for example), there is a great risk of contamination and of damages.

Other types of recognized waste are the following:

* similar to urban: those that are not classified as dangerous and that correspond to waste from commercial stores, offices and private homes;

* inert: are wastes that do not undergo any physical or chemical transformation, that are not biodegradable and that do not produce negative effects on other materials when they come into contact with them. In other words, they cannot generate environmental pollution or have a negative impact on the health of living beings. The level of contaminant type components that they possess, as well as the possibility of separating their insoluble parts from the soluble ones, must be insignificant. The most common are the pieces of glass, the bricks, the concrete and the rubble.

Since the materials used to build all legal products are properly documented, it is possible to check their properties to know if their waste should be considered hazardous.
