Hazardous Waste Management: Can Anyone Do It?
Hazardous waste is one whose properties make it harmful to the environment and human health. These hazardous wastes can be created from many sources, from industrial manufacturing, chemical production, or generated by other types of industries.
These wastes -which can be present in any state- are capable of causing damage due to an inadequate treatment of hazardous waste and their consequences could be really negative. For example, people living near waste disposal sites may be in a very vulnerable position.
For all these reasons,
governments strictly regulate the management of waste and hazardous waste. And
thus be able to remedy existing problems and even prevent future damage. The
destruction of this type of waste must be carried out by a Hazardous Waste Management Authorization.
In this article, we explain the
different forms of hazardous waste treatment that exist to guarantee proper
treatment.
When Waste is considered hazardous?
Not all waste is considered toxic
or dangerous. To have this consideration, they must meet a series of
characteristics.
Although not all the
characteristics are necessary to consider a toxic waste, to be so it must be an
element:
Explosive or easily ignited.
Toxic and
Oxidant
With carcinogenic properties.
The fact of complying with these
properties make waste dangerous and, therefore, its treatment must be special
and qualified.
Types of hazardous waste treatment
There are several types of
hazardous waste treatment. It's always best to reduce the amount of waste at
its source, or even recycle materials that can be productively reused. However,
these measures do not solve the problem of the disposal of this waste.
Hazardous waste treatments are
various, since there are several methods that can be applied:
Chemical method
Some of the chemical treatments
are ion exchange, oxidation and reduction, chemical precipitation and
neutralization. This method is used to transform hazardous waste into non-toxic
gases, by modifying their chemical properties.
For example, cyanide can go
through an oxidation process making this poisonous residue a non-toxic product.
Another chemical process would be the separation of water, which allows
extracting the water from some organic waste, and then eliminating it through
incineration.
Thermal method
This method uses high
temperatures for the incineration of materials. The thermal method can not only
detoxify some organic materials but also completely destroy them.
There are special thermal
equipment used for the incineration of waste in solid, liquid, or sludge state.
Despite its effectiveness, this the method has a downside, and that is that the incineration of hazardous waste by the thermal method can cause air pollution.
Biological method
This is used for the treatment of
organic waste, such as those from the oil industry. One method of treating
biologically hazardous waste is soil cultivation.
This technique consists of mixing
the waste with the soil surface in a suitable area of land. It is possible
that some types of microbes are added in order to metabolize waste and some
nutrients.
There are cases where genetically
modified bacteria are used. Microbes are also used to stabilize hazardous
waste. This process is called bioremediation. It should be noted that these
soils are not suitable for growing food.
Physical method
While the previous methods
manipulate the molecular shape of the waste, the physical treatment consists of
concentrating, solidifying, or reducing the volume of waste. Some of the
processes used are evaporation, flotation, sedimentation, and filtration.
Another process that has become
very popular is solidification, which consists of encapsulating waste in
asphalt, plastic, or concrete. Encapsulation produces a solid mass resistance to
leaching. It is also possible that the waste is mixed with fly ash, water, and
lime to form another type of solid similar to cement.
Who is responsible for the
disposal of hazardous waste?
Carrying out hazardous waste
disposal processes are not something that anyone can do, but you must be trained
for it and have the appropriate certifications for it.
We have all the certifications
and highly qualified professionals that allow us to carry out the tasks of
eliminating toxic and dangerous waste without representing dangers for third
parties.
If you want to get rid of
hazardous waste at an industrial level, always bet on certified companies. This
will ensure not only that they have the appropriate professionals, but that
they have been evaluated and validated by state agencies that are in charge of
controlling the treatment of these discharges. Contact us and left to
professionals treating hazardous waste!
