Asbestos is very common in Sydney old homes as it was widely used because of its appealing properties. Asbestos is cheap and famous for its insulation properties, sound absorption, fire resistance, and strength. Because of this, many houses built before 1982 especially in the 1950s and 1960s in Sydney has a high probability of containing asbestos.
Laws governing asbestos removal
Due to the harmful nature of asbestos, the Australian government put in place laws that governed the removal and treatment of asbestos.

Asbestos can also be transformed to a harmless silicate glass through recycling. But this requires a thermal decomposition of asbestos in 1000 to 1250 degree Celsius and the end product becomes silicate glass.in an industrial manufacturing process, asbestos and waste containing asbestos can be subjected to a microwave heat treatment to make products such as porcelain stoneware tiles and ceramic bricks.
Geotech drilling and asbestos
