Asbestos was commonly used in construction materials due to its fire-resistant and insulating properties. It is a naturally occurring mineral. Nevertheless, it was later detected that inhaling asbestos fibres could be dangerous and cause serious health issues such as mesothelioma (a type of cancer that affects the lining of the lungs and abdomen), lung cancer, and asbestosis (a chronic lung disease that causes scarring of lung tissue).
Therefore, it is extremely important to dispose of asbestos properly to prevent the release of asbestos fibres into the air, which can be inhaled and cause health problems. Improper disposal of asbestos can also contaminate soil and water, posing a risk to the environment and potentially spreading the material to new locations.
To ensure the safe disposal of asbestos, it is recommended to hire a licensed asbestos abatement professional to remove and dispose of the material. The professional should follow proper procedures associated with asbestos collection. It is important to contain the asbestos fibers as well as prevent their release into the environment during removal, transportation, and disposal.
How do professionals handle and dispose of asbestos?
Asbestos is a hazardous material that must be handled and disposed of with care to avoid releasing toxic fibers into the air.
Here are the steps that professionals typically follow to handle and dispose of asbestos:
- Identification: Before handling or disposing of any material suspected to contain asbestos, the professionals have it tested by a qualified professional to confirm its presence.
- Planning: Once the presence of asbestos has been confirmed, a plan for handling and disposing of it is developed. This plan considers the type and condition of the asbestos-containing material, the location, and the safety precautions that will be necessary to protect workers and the environment.
- Preparation: Before beginning the removal work, professionals prepare the work area by sealing off all doors, windows, and other openings to prevent the spread of asbestos fibers. They wear protective clothing, including a protective suit, gloves, and a respirator.
- Safety protocols in the work zone: The HVAC system is disabled, and a HEPA vacuum is used for cleaning after the completion of the abatement. A decontamination enclosure system is installed for workers to remove their contaminated tools, clothes, and shoes.
- Removal: Asbestos-containing materials are carefully removed, taking care not to break or damage them, which could release fibers into the air. Depending on the type of material and its condition, professionals use specialized tools and techniques to remove it, such as wetting it down to reduce dust.
- Disposal: Asbestos waste is disposed of in special asbestos disposal facilities, which are designed to prevent the release of fibers into the environment. The waste is packaged and labeled properly, then transported to the facility in a manner that complies with all relevant regulations.
An attempt to handle asbestos without proper training and equipment can be extremely hazardous and should be avoided.

Recycling
Microwave thermal treatment is a process that uses microwave energy to convert asbestos into a more stable, non-friable material, such as ceramic bricks or porcelain tiles. This process works by heating the asbestos-containing material to high temperatures using microwave energy, which causes the asbestos fibers to break down and re-form into a ceramic material.
The process is typically carried out in a specially designed microwave oven, which is capable of generating the high temperatures required to convert the asbestos. The oven has multiple safety features, including insulation and shielding, to prevent exposure to hazardous asbestos fibers.
Once the asbestos-containing material has been subjected to microwave thermal treatment, it is typically ground into a fine powder, which is then molded into the desired shape and fired to produce ceramic bricks or porcelain tiles. The resulting material is much more stable and non-friable than the original asbestos, making it safe for use in construction and other applications.
Overall, the microwave thermal treatment of asbestos is an effective and efficient way to convert this hazardous material into a more stable, non-toxic form, while minimizing the risks associated with exposure to asbestos fibers.
