Modern-day households contain several products some of which are very dangerous. Products are made dangerous by the ingredients they are made out of or the materials that make them. Some good examples of household products that have been categorized as hazardous include ammunition, refrigerants, paints, solvents, aerosols, electronics, caustics, certain batteries, pesticides, and automotive wastes among others.
The products named above are only safe when their condition is still good and when proper use is made of them. However, they pose health risks to animals and people when they are misused or expire. That makes it necessary that they are disposed correctly. The aim of this article is to name and discuss some of the main methods of hazardous waste disposal that are currently in wide use in the world.
When proper disposal is done, the wastes offer minimum or no risk at all to people, animals and the environment. On the contrary, improper or poor disposal can be detrimental. For instance, if the materials get their way into underground water sources or into gutters, they may poison water, making it unsafe for human consumption. They also contaminate soil and render it unsuitable for agriculture.
Today waste materials are disposed through many different methods. Recycling, incineration, use of cement, pyrolysis, and landfills are among the methods in common use. Concerned parties encourage people to use recycling because besides being economical, it is eco-friendly. Recycling is the process of finding other applications for products after they fail or cannot perform the original function for which they were defined. The main downside in this method is that it cannot be used in all situations or products.
The second method that is in wide use is incineration. This method involves destroying the harmful materials under very high temperatures. This process takes place inside a special chamber referred to an incineration chamber or incinerators. The materials are reduced to ash, which is harmless and can be disposed with ease without posing a threat to people or the environment.
Incineration has always raised concern because of the harmful gasses that are released into the environment during combustion. That effect has been countered by the development of better incinerators with the ability to eliminate any possibility of emission of gasses into the environment. Modern incinerators also generate energy during combustion to be used to in other processes and systems. Pyrolysis is a version of incineration, but combustion never occurs because the environment is inert.
Hazardous materials have traditionally been disposed in landfills before better methods emerged and that changed. New methods have been adopted because of the seepage of harmful materials into underground water, which occurs in landfills. This kind of pollution is irreversible. However, some places still use this method although to a low level.
Cement has also been found to be effective for treating and disposing hazardous material. It makes disposal easier by solidifying and stabilizing the material. When treated with cement, the characteristics, toxicity, and ability to transmit the contaminant is reduced. The use of cement is however limited.
