Asbestos is in many ways an ideal construction material: tough, light, durable, fire-resistant, and very cheap. Asbestos, once known as the “magic mineral”, has been widely used as a constituent in buildings and building materials, machines, transport vehicles, and consumer products. Asbestos has a known historic use going back at least 4,500 years. Asbestos is the collective term for naturally occurring silicate minerals with a crystalline structure and a fibrous character. Total bans on asbestos use have introduced in over 50 Countries, including those in European Union, Japan, Australia, and South-Africa. In spite of bans, the total global use of asbestos lies still at the level of about two million metric tons a year.
