Asbestos is found in homes and buildings due to its widespread use in the 20th century, and when asbestos fibers are disturbed, the mineral can become deadly. Asbestos recycling can convert the material into a harmless glass, but it is not common today. Keep in mind, this type of asbestos removal and repurposing should be left to professionals.

Can Asbestos Be Recycled?
Short Answer: Yes

Asbestos recycling occurs when the material is transformed into completely safe silicate glass at very high temperatures. The glass can then be used to make ceramics and stoneware.

That said, asbestos recycling should never be attempted without an asbestos professional. Inhaling asbestos fibers can cause mesothelioma, a rare and deadly cancer, as well as other asbestos-related diseases.

If you have an older home or office building and suspect it contains asbestos, do not try to remove it yourself. Contact your local hazardous waste center to find an asbestos recycling center or asbestos recycling plant near you.

Why Recycle Asbestos?

Asbestos recycling is not an easy process, and costs are very high. That said, there are many important benefits.

Benefits of asbestos recycling include:

  • Asbestos recycling saves valuable landfill space, as the material won’t get sealed and buried
  • The glass created from asbestos recycling can be used to make new products, such as those used in roads or construction
  • After the asbestos recycling process, the material is no longer toxic, which reduces the chances of mesothelioma and other asbestos-related diseases to occur

How to Recycle Asbestos

The process for recycling asbestos waste is an alternative to the “wrap and bury” method used for traditional asbestos abatement.

The steps involved in asbestos recycling include:

  1. Removing the asbestos-containing material
  2. Washing the material in a hot base solution followed by acid to dissolve the asbestos fibers
  3. Melting and vitrifying the solution to create glass or ceramic material (the extremely high temperatures used in this process destroy the asbestos fibers)
  4. Recycling the glass or ceramic

Recycling and Asbestos Products

Asbestos was used widely from the 1930s to the 1970s to make thousands of products. Because it was cheap, versatile, and resistant to fire, asbestos was commonly used in the military, especially on U.S. Navy ships. It was also used in countless industries and in homes.

As asbestos-containing products are used or damaged, asbestos fibers are released into the air. Inhaling or swallowing these fibers can be deadly, especially later in life.

Did you know?

Asbestos was used so commonly that millions of people were exposed to the deadly material.

Asbestos-Containing Products in Vehicles

Due to its heat-resistance, asbestos was used in auto parts that involve constant friction.

Asbestos could be found in these vehicle products:

  • Brake pads and linings
  • Clutch linings
  • Fume hoods
  • Heat seals
  • Hood liners
  • Transmission plates

Asbestos-Containing Products in Navy Ships

Every U.S. Navy ship built before the 1980s contained asbestos to reduce the risk of fires. Neither the U.S. military nor the general public knew asbestos was dangerous, as asbestos product manufacturers hid the deadly truth for decades.

Asbestos was considered perfect for insulation in steam pipes and fuel lines. Since asbestos is non-conductive, it was used to coat miles of electrical cables.

Asbestos could be found in these vehicle products:

  • Cement powder and mortar mix
  • Deck and floor tiles
  • Electrical cables and coatings
  • Fuel lines
  • Gaskets
  • Insulation
  • Meters
  • Pumps and hydraulics
  • Paint and wallboard
  • Sealants and adhesives
  • Soundproofing materials
  • Steam pipes
  • Valves

Non-military ships made before the 1980s also contained many asbestos-based products.

Asbestos-Containing Products in Buildings

Before regulations on asbestos began to occur, it was commonly used in the construction of buildings and homes as insulation.

Because it is fireproof, asbestos was used in:

  • Cement
  • Drywall
  • Floors
  • Heating equipment
  • Insulation
  • Paint
  • Roofing shingles
  • Siding
  • Tiles

There is no safe level of asbestos exposure, and even a single fiber can cause mesothelioma or other illnesses decades later. For this reason, if you own a home or building made before the 1970s, it is a good idea to find out if asbestos is present.

Testing Your Home for Asbestos

Testing for asbestos in your home can help reduce the chances of exposure. Although asbestos fibers are virtually harmless if left alone, once they are disturbed, they enter the air and can be easily inhaled or ingested. Then, they can cause decades of irritation and even cancer later on.

You may want to get your property tested for asbestos if:

  • You’re carrying out a DIY remodeling project
  • A natural or manmade disaster disturbed the building’s structure
  • The structure was built before 1980
  • You notice crumbled, worn, or broken asbestos-containing materials

Once you know whether the toxic mineral is in your home, removal and possibly even asbestos recycling may be required. Please note, however, asbestos testing and abatement MUST be performed by a professional.

Here are a few other things to remember if you believe your home may contain asbestos.

Avoid Damaged Asbestos

Don’t go into any part of your home that contains damaged asbestos-based products. If you aren’t sure if asbestos is present, leave the area alone and treat it as though it is.

Don’t Use At-Home Testing Kits

At-home testing kits allow you to take a sample and send it to a lab to test for asbestos. That said, the Environmental Protection Agency (EPA) recommends using accredited professionals to test for asbestos.

The main reason for not using at-home kits is that most untrained people are unable to tell if something may contain asbestos. A trained professional, however, knows how to test areas without disturbing the asbestos fibers, which could worsen contamination.

Don’t Remove Asbestos Yourself

While it is legal to remove asbestos from your home in some states, you may put yourself at risk of exposure without proper training. It is best to not attempt removal or asbestos recycling under any circumstances.

Removing Asbestos From Your Home

If asbestos recycling or removal is required for your home, there are generally two types of asbestos professionals you may need.

  1. Asbestos Inspectors: Those who inspect homes and buildings to assess the likelihood of asbestos, take samples, and advise on corrections needed
  2. Asbestos Contractors: Those who make repairs or handle asbestos removal

Once you know whether the toxic mineral is in your home, removal and possibly even asbestos recycling may be required. Please note, however, asbestos testing and abatement MUST be performed by a professional.

Tips for Working With Asbestos Professionals

While working with a professional on asbestos recycling or removal projects, there are several things to consider.

Some tips to keep in mind include:

  • Use an accredited asbestos inspector
  • Have any suspicious materials tested by a laboratory
  • Fill out a construction and demolition waste acceptance form
  • Be sure the test results are available as needed

Asbestos Recycling vs Abatement

Asbestos abatement is the sealing and removal of asbestos-based products. It is currently much more common than asbestos recycling.

Recycling asbestos costs three times as much as standard removal. Contractors also need additional approval from the EPA if they want to pursue asbestos recycling, making the process more complex.

Asbestos Removal and Disposal Laws

As the dangers of asbestos-containing products became widely known starting at the end of the 1970s, the U.S. government began passing laws to ensure the mineral would be properly removed and disposed of.

Some laws dictating asbestos use and removal include:

  • Toxic Substances Control Act (TSCA)
  • Asbestos Hazard Emergency Response Act (AHERA)
  • National Emission Standards for Hazardous Air Pollutants (NESHAP)

Although asbestos laws and regulations are common, they are still widely debated.

Is Asbestos Banned?
Short Answer: No

Despite the health risks that asbestos exposure is known to cause, there is not a full ban on asbestos, even today.

In 1989, the EPA made a final ruling on the Asbestos Ban and Phase-Out Rule, banning most asbestos-containing products. However, the regulation was overturned in 1991, with dozens of products still being manufactured today.

Asbestos Recycling Recap

The main thing to remember about asbestos recycling or removal is to never attempt it yourself. The material is deadly, and there is no safe level of exposure.

Some other important things to remember include:

  • Asbestos recycling turns dangerous asbestos fibers into a harmless glass, but it is not yet common due to costs.
  • Always go to a professional for asbestos recycling or removal.
  • Use caution and assume asbestos is present anywhere it is suspected. Inhaled asbestos fibers cannot be expelled from the body, causing health problems, such as the deadly cancer mesothelioma.
  • Although asbestos is still not banned in the United States, it is highly restricted, and its use and removal are closely regulated.
