Many dangerous materials and products are contained in modern-day households as lifestyles and demands change over time. Products contain many ingredients that have the potential of being harmful and dangerous if the right steps are not taken in eliminating them from the house setting. Some of the materials that most states categorize as hazardous in the home setting include solvents, aerosols, electronics, ammunition, refrigerants, paints, certain batteries, pesticides, automotive wastes, and caustics 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.
Incineration is another method that is used widely. It involves destroying materials through burning at extremely high temperatures. The equipment used for the process is called an incinerator or an incineration chamber. The end result is ash, which is harmless and easier to get rid of without causing any harm to people, animals, and the environment.
A lot of harmful gasses are emitted into the environment as the materials burn, and that has always raised concern. However, with recent advancements in technology, incinerators have been developed with capabilities of preventing emission of harmful gasses. In addition, such incinerators can generate energy from the combustion process to power other systems. Pyrolysis is similar to incineration only that the process occurs in an inert environment to prevent combustion.
Before the emergence of better methods, landfills were the traditional way through which hazardous materials were disposed. Technological advancements and the adverse effects of landfills prompted new methods to be developed. Harmful materials seep into underground water reservoirs, causing contamination and pollution which can never be reversed. Although limited, landfill usage is still ongoing in certain countries and states.
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.
