Waste is those objects that we produce in our daily activities when they lose their usefulness or value, but they can be recycled and then reused.
On the other hand, wastes are those that once finished their use can no longer be reused and become dangerous elements when discarded in a careless way.
In Mexico, the Official Mexican Standard "NOM-052-SEMARNAT-2005" establishes that waste is those that can no longer be reused and is highly harmful in any of its states (solid, liquid, gaseous or pasty), for be corrosive, reactive, explosive, flammable, toxic and biological-infectious, and that due to its way of handling can present a great risk to the environment and the health of the population.
There are various types of hazardous waste.
It is said to be corrosive when they can undergo chemical reactions and release toxins. Most are acids or bases such as nitric acid, sulfuric acid, nitric acid, chromic acid and sodium hydroxide among others.
The reagents are nuclear waste that emit beta and gamma radiation, which within 5 minutes of coming into contact with air ignites without the need for any other alternative source.
The explosive waste They are what are capable of producing a triggering reaction or decomposition on its own or when exposed to high temperatures, for example: peroxides, dynamite, insecticides, acids and pesticides, to name a few.
The toxic waste such as cyanide, medicines, heavy metals, paints, solvents, dyes, lacquers and several of the same type, they are dangerous for health and the environment, since given their composition, when disposing of them they cannot be reused and they end up in inappropriate places causing environmental disasters.
The flammable they refer to that substance capable of causing fire by friction, absorption or spontaneous chemical changes, such as alcohol and phosphorus. And finally, there are biological-infectious ones, which are those that are generated during activities in contact with human and animal health in hospitals, laboratories, veterinarians and research centers. An example of these are surgical supplies, used syringes, organs or tissue parts, and animal carcasses.
Hazardous waste can pollute water resources and contaminate the water, as also the air; or even by contact create very serious allergic reactions and intoxication in humans and animals.
In Mexico, more than 85 thousand tons of waste and residues are collected daily, which is enough to fill the Azteca Stadium, which are mainly generated in homes, buildings, streets and parks. It is estimated that said waste is composed of: 32.6% hazardous waste, 31% organic waste, 14.2% paper and cardboard, 9.8% garden waste, 6.6% glass and 5.8% plastic.
Now that you have this information, we invite you to separate trash of your home or work by types of waste, so that when the garbage truck passes you can differentiate them and they are separated in an appropriate way so that it is easier for them to recycle many of these wastes and minimize their impact on the environment.
In the case of hazardous waste, there are waste collection and management centers in all municipalities and delegations of Mexico to receive all types of materials, which are separated, classified or reused.
Hazardous waste is a public health issue, as its effects directly or indirectly pose a health risk. If you know about companies close to you that contribute to the pollution of the environment with the generation of industrial waste of this nature, you must notify the authorities so that they can inspect it and determine if their management plan is adequate. or if they present a risk to your community.
