Asbestos is a naturally occurring mineral that was once widely used in the construction industry. It was added to building materials to make them stronger and more fire-resistant. However, it was later discovered that asbestos can pose serious health risks, particularly when it is disturbed and the fibres become airborne. Breathing in asbestos fibres can cause lung diseases, such as mesothelioma and asbestosis.

Because of these health risks, asbestos must be disposed of properly. The UK government has strict regulations for the disposal of asbestos, and failure to comply with these regulations can result in fines and other penalties. As a hazardous substance, asbestos must be handled carefully and disposed of in specially designated facilities.
