Asbestos recycling creates safe cement substitute

Asbestos Garage Roof Removal

A demonstration project to recycle asbestos-containing products into a safe reusable material has been declared a success.

As written on The Construction Index, Thermal Recycling claims to have shown that its Calmag material is an effective cement substitute.

Calmag is made from cement roof sheets containing chrysotile asbestos. Thermal treatment changes the chemical and physical composition of the asbestos, producing an asbestos-free material that is then crushed. The end product can be used as a sustainable aggregate that is particularly useful for road building, it is suggested.
