Asbestos Cement Removal and Conversion

Asbestos Removal and Conversion

Removal and conversion of asbestos cement Asbestos cement is a mixture of cement and asbestos. Asbestos usually makes up about 10-15 percent of all material. It is often used as corrugated roofing on sheds, garages and farms. It was also used to make drain pipes, hoses, water tanks and other products. As the cement ages, asbestos, a known carcinogen, may be exposed and pose a health hazard. According to the Ministry of Environmental Protection, there are currently about 85 million square meters of asbestos cement throughout the country - most of it in the form of roofs on private houses and other buildings. Asbestos is a naturally occurring fibrous silicate mineral. Inhaling asbestos can lead to various lung conditions, including mesothelioma, asbestosis and lung cancer. Workers removing asbestos must wear dust masks and disposable protective clothing. After removal, asbestos products are usually buried in landfills. However, asbestos cement can be processed, converting the asbestos into a harmless material. The resulting material can be used as a sustainable aggregate especially useful for road construction. The use of converted asbestos cement aggregate will reduce the need to mine other aggregate materials, and prevent CO2 emissions. CO2 embodied in the aggregate can be arranged on the surface of the road and in other construction.
