There are various methods of hazardous waste disposal, depending on the type of waste. Household hazardous waste can be disposed of in regular trash cans, but industrial waste must be placed in appropriate containers. Recycling, neutralization, and concrete processing are effective methods, while incineration and landfilling are controversial.
There are many different types of hazardous materials disposal. How hazardous waste is disposed of depends largely on the type of waste on hand. While some waste is considered toxic, others can be recycled and made into another type of product. Before any hazardous waste can be disposed of, the basic types of waste must be clearly defined.
Hazardous household waste includes paints, automotive materials, pesticides, electronics, coolants, mercury-containing items, aerosols, cleaning products, batteries, and radioactive waste. All of these things are considered hazardous materials and each of these items must be disposed of properly. However, many countries around the world lack the budget to set up a separate disposal area for household waste. Therefore, a fair amount of the items listed above can be placed inside a regular trash can. Before disposing of any household waste, it is best to check with your local authorities for the correct method of disposal.
Flammable, corrosive, toxic or reactive industrial waste should be placed in appropriate waste containers. There are special containers for all types of industrial waste, including medical waste. Industries and organizations that do not dispose of waste properly are often heavily fined.
Many types of household hazardous waste can be recycled. Batteries, electronic circuits and other objects can be collected or transformed into new products. Also, some types of industrial waste, such as ash, can be recycled. Another type of hazardous material disposal includes concrete processing. Various materials can be mixed with the concrete to change the properties of the original material. Because cement can reduce the amount of toxins in a material, this process is highly effective.
While most types of hazardous waste cannot be modified, some wastes can be effectively neutralized. During the neutralization process, hazardous elements are removed from the waste itself, creating a different kind of hazardous materials disposal. The result of the neutralization process is a non-toxic material.
Incineration is another type of hazardous materials disposal that was once quite popular, but is no longer the case. The incineration process involves burning hazardous waste until it is no longer harmful. While this method eliminates hazardous waste, it also allows harmful toxins to enter the atmosphere in the form of smoke. Therefore, the incineration technique is being phased out.
Finally, the disposal of hazardous materials may include landfilling. Landfills are large caves, treatment plants, underground shafts, or other earthen openings used as landfills. When waste is buried under a patch of soil, it is thought that this waste will eventually disintegrate. However, this process is highly controversial, as many people do not believe that landfills effectively eliminate waste problems.
