What is asbestos made of?
Asbestos
Asbestos can be recycled by transforming it into harmless silicate glass. A process of thermal decomposition at 1,000–1,250°C (1,800–2,300°F) produces a mixture of non-hazardous silicate phases, and at temperatures above 1,250°C (2,300°F) it produces silicate glass.[101] Microwave thermal treatment can be used in an industrial manufacturing process to transform asbestos and asbestos-containing waste into porcelain stoneware tiles, porous single-fired wall tiles, and ceramic bricks.[102]
